Crystalline Silica – Hazards and Respiratory Protection

Crystalline silica is ubiquitous in various fields of activity, such as construction, quarries, glass works or even foundries. alveolar powder In its form, it poses a real danger to the health of workers when inhaled. Our experts tell you this harmful dust features and to be used will demonstrate respiratory protection equipment.

Dangers of silica

What is crystalline silica?

Silica is an element found in many minerals in different forms, especially in crystalline or amorphous form. Its pure form crystallizes under different temperature and pressure conditions. Among them: quartz , tridymite And cristobalite is found .

Crystalline silica is a common element in the earth's crust. Indeed, sand, granite, concrete, stone, etc. It is also found in many mineral-based construction materials such as. less than 5 micrometers Respirable alveolar powder of crystalline silica (defined by its ability to reach the lung alveoli), having a size smaller than (microns), produced by many professional activities . A real thing when inhaled health hazard creates .

Health effects

Crystalline silica, known It is classified as a human carcinogen (group 1) . Exposure to and inhalation of such dust A lot It may cause health problems:

skin irritations
eye inflammation
bronchitis
emphysema
tuberculosis
immune system damage

Mines and quarries

Silica: regulation and prevention

Regulations

Hazards caused by the presence of crystalline silica in many occupational activities strict regulations It leads to . In France and Europe, exposure to this substance is limited by law to certain levels.

Occupational exposure limit value over 8 hours
Crystalline silica :	OEL mg/m3
alveolar quartz dust	0.1mg/m3
alveolar cristobalite dust	0.05mg/m3
alveolar tridymite dust	0.05mg/m3

Additionally, since 1997 crystalline silica has been classified as a carcinogen by IARC (WHO International Agency for Research on Cancer). This classification, and its recognition by various national authorities, allows employers to identify certain CMR agents (carcinogenic, mutagenic or toxic to reproduction) requires regulatory obligations.

Preventing the danger of silica

Dangers of crystalline silica and in the face of applicable regulations, prevention plays an important role in various applications exposed to such respirable dust. This dust in working environments Many arrangements can be made to minimize its formation. Among these collective protection and security measures we note:

wet job
workstations isolation
Use of dust extraction cabinets
mechanization of hazardous work
risk assessment
working atmosphere control
enhanced monitoring of exposed workers
thorough cleaning of exposed areas
Use of PPE (personal protective equipment)
Proper care of PPE used

Finally, in addition to these preventive measures, such as asbestos respiratory protection, concerned persons (employees, workers) need to be systematically informed about the risks posed by the presence of crystalline silica.

Silica protective equipment

Crystalline silica exposure prevention methods should be accompanied by personal protective equipment. respiratory protection mask use and dust jacket Wearing it ensures that exposure to danger is minimized.

Silica respiratory protection mask

In addition to various precautionary measures, to ensure the safety of workers exposed to crystalline silica into fine particles It is also important to wear a specially adapted respiratory protection mask.

GVS Elipse mask

Nowadays ultrafine particles There are very few dust masks that can filter . In fact, most gas mask filter manufacturers offer equipment that filters particles in the 1 to 0.6 micron range. Breathable crystalline silica powder with a diameter of less than 5 microns Since particles up to 0.3 µm are regularly present, these are not filtered out by protective devices. Exposure to such particles requires the use of very high-performance filters.

For this purpose, our experts recommend the use of the GVS Elipse mask with P3 filter.

This respiratory protection mask is ergonomic, easy to use, very comfortable to wear and high precision filters has . GVS mask technology, HESPA® (High Efficiency Synthetic Particulate Air Filter) multilayer pleated filter uses . These P3 filters have a minimum efficiency of 99.95% or greater for 0.3 micron particles. They have a Nominal Protection Factor (PNF) of 40 (reducing dust concentration between the outside and inside of the mask by 40%). These filters are effective up to a maximum of 50 times the OEL. All these features make this mask ideal for protection against alveolar crystalline silica dust.

Powered air-purifying respirators for long-term operation

Choosing the Right Fall Protection

Working at heights can have dramatic consequences and requires special skills, especially in terms of safety and standards. Many professionals in companies are exposed to a major risk on a daily basis: falling from a height. Nowadays, the market is filled with many models of fall protection harnesses. From the standard seat belt to the more complete model, which one should you choose for the best protection?

Protection against danger of falling

Once an employee is exposed to the risk of falling, the employer is obliged to identify the risks in order to identify preventive measures to protect the employee. In France, individual protection complements collective protection. Both types of protection are essential and complementary to ensuring a safe working environment. By “collective protection” we mean all fixed installations: floor markings, non-slip floor coverings, installation of handrails, etc. In addition to these devices, Personal Protective Equipment (PPE) is used to ensure worker safety by eliminating or reducing risks at the source. In case of risk of falls, fall protection becomes essential and should be applied regardless of the activity. Fall protection is becoming essential PPE for professionals and companies working at heights (scaffolding, roofs, work platforms, ladders, etc.).
3 basic components of fall protection: fall arrest harness, anchor point, attachment system.

safety belt

A fall arrest harness should be worn during any work at height. It complies with NF EN 361 standard and can be adjusted for every operator thanks to its adjustable straps and buckles. There are many types of harnesses available, each for a different use.

Ports

The attachment point can be fixed (type A) or movable (type B, for example a tripod). For greater safety, it is recommended that the port be located above the user to reduce drop and pendulum effects. It must be able to stop and restrict the operator in case of falling from a height.

Linked fall arrest system

A linkage and/or energy absorption system connects the harness to the anchor point. Attachment and energy absorption systems come in different forms: safety rope, retractable fall arresters, etc…

3 tips for choosing the right fall arrester

Decline factor

When the anchor point is at or above the seat belt anchor point, the operator is safe. However, if an energy absorber is not used when the drop factor is equal to 1, the impact can be severe and range from 900 to 200 daN. When the drop factor is equal to 2, the attachment point is located at or below the operator's feet.

This is the minimum required vertical free fall distance of 6.5 meters without obstacles. This height is calculated as follows: A+B+C+D

A = Total length of fall arrest device used
B = stopping distance according to the fall arrest device used
C = Height from the fall arrest attachment point of the seat belt to the user's feet
D = 1 m safety margin required by the standard

minimum clearance

pendulum effect

Pendulum fall occurs when the user is close to the fall risk zone without being fixed vertically to the anchor point.

The risk of injury increases due to the user's uncontrolled shaking after falling.

Fall arrest safety belts

“Economy” fall arrest harness NUSL1ECO and NUSL2ECO

NUSL ECO harnesses are “entry level” fall arrest harnesses for occasional use or heavily soiled jobs. The NUSL1 ECO harness has only one rear anchor point on a “D” suitable for working on scaffolds or platforms. NUSL2 ECO also has a sternal attachment point on the webbing loops to be attached.

Suitable for the following industries : aerial work platforms, roof, steel construction, construction
Conforms to the following standard : EN 361

Pack & Go fall arrest harness

Pack & GO is a fall arrest harness with integrated carrying bag. It is comfortable to wear and the integrated storage bag makes it particularly practical. It has 2 attachment points: 1 sternal point on a textile buckle and 1 dorsal point on a metal “D”. Complies with EN361 standard (personal protective equipment against falls from height).
Suitable for the following industries : construction, steel construction, scaffolding, aerial work platforms, roofing

VIT'O TEC is a fall arrest and rescue harness for use in confined spaces. An extension strap has a back attachment point and a sternum attachment point with two textile buckles for fall arrest and rescue. It also includes a special ergonomic belt for wearing the self-rescue mask.
Suitable for the following industries : sanitation
Conforms to the following standards : EN 361, EN 1497

Ports

There are different anchor points, each with their own type of use. However, all anchors must provide a safe fall arrest system and comply with the EN 795 standard.

Available ports

For the first time in a season, you can be sure that the structure will be built very solidly to support the weight of the user. As is known, the structure can withstand up to 12 kN (approximately 1.2 tons) and can support human maximum impact and/or superior energy up to 600 daN. Anchor point selection can be: lifelines, equine rings, four-leaf clovers, etc…
Choosing the location of the attachment point is also important because it is definitely a risk factor of the parachute for the user.

safety tripod

To make your choice easier, we recommend PPE that complies with the 2016/95 Directive and the EN 795 B standard.

The safety tripod should also be made of reinforced aluminum legs and telescopic construction to allow the operator to adjust the length of the unit.

Most often the tripod comes with a self-retracting fall arrester with rescue winch, lifting winch (optional), cable swivel pulleys under the tripod head, and a carrying bag.

Connecting fall arrest systems

Energy absorbing (EN 355) lanyard (EN 354) is a connection system consisting of a lanyard and two connectors up to 2 m. Elastic lanyards offer extra comfort due to their elasticity. For example, a belt lanyard will be 40% shorter in the retracted position than a standard belt lanyard. The system ensures that the operator's movements are safe and limited around the anchor point.

Retractable fall arresters

Fall arresters are available in different lengths of straps or cables. On the one hand, the strap fall arrester is specifically designed for work at height (AWP, scaffolding, roofing, etc.) with a short attachment length (2 to 5 meters). It is very lightweight and is equipped with a high-density polyethylene rope that can be automatically retracted. On the other hand, the cable fall arrester is heavier and bulkier than the webbing reel. It is equipped with a very strong steel cable and is especially designed for difficult or serious areas such as manholes (risk of cutting) or narrow spaces.

Fall arrest equipment standards

NF EN 354 : Mooring ropes (max. length: 2 m)
NF EN 355: Energy absorbers
NF EN 358: Work positioning systems
NF EN 360 : Automatic fall arrest system
NF EN 361, NF EN 358, NF EN 813, NF EN 1497: Full fall arrest safety belts
NF EN 362: Connectors
NF EN 795 : Anchor points (type B)

Good to know this:

The manufacturer's instructions are mandatory and must be written in French
The regulatory “CE” marking must be affixed to every product
Instructions must include a reference to Regulation (EU) 2016/425
harnesses should be checked every 12 months

You must protect yourself!

When you know that 10% of work accidents in France are caused by falls from height, protection becomes and should be a priority. Don't neglect other PPE such as safety shoes, helmets and protective gloves. These can always protect you. Security is priceless and should not be taken lightly. a deliberate
No pun intended, but don't fall off the train and choose the equipment that best suits your needs!

Biogas Analyzer For Waste Management And Recycling

biogas production – through plants or digesters – and recycling is encouraged, but biogas remains a factor in global warming. These production, purification and evaluation processes are therefore with biogas monitoring devices requires appropriate control and follow-up. Fixed and/or portable equipment for the safety of employees in power plants, treatment and production centers biogas analyzers are required.

Biogas composition and its effects on health

Biogas consists of various gases with different properties. These include methane ( CH4 ), the primary gas that makes up 50% to 70% of biogas; This is a flammable gas used primarily in power plants (gas turbine). Biogas also contains hydrogen sulfide (H2S), a poisonous gas, and carbon dioxide, an asphyxiating gas.

It consists of (CO2) and water vapor (H2O). Since it consists mostly of methane, biogas is primarily It is a flammable and flammable gas. . Due to the presence of hydrogen sulfide, it is also is poisonous and corrosive . Anaerobic fermentation can cause discomfort to humans. It also refers to bacteria and particles. Therefore, the presence of biogas must be measured and monitored continuously ; usually a ; usually a

Brief exposure to high concentrations does not cause death. Symptoms of this type of exposure include respiratory and eye irritation. In case of chronic exposure, organ failure affecting the digestive system (abdominal pain) and the brain (chronic fatigue) may occur.

Covid-19 And CO2 Monitors

At the beginning of the school year, faced with the coronavirus and its aerosol mode of transmission, CO2 monitoring and especially in schools, offices and all occupied spaces and especially in schools, officesdCO2 covid sensor is proving to be an effective solution. Measurement of carbon dioxide in occupied indoor spaces, in ambient air and in all occupied spaces the presence of polluting aerosols It makes it possible to evaluate and ventilate a room accordingly. The GTC Industrial team, experts in gas detection, examines this type of monitoring equipment and offers the ideal solutions for occupied spaces: CO2 detection column And indoor air quality CO2 sensor .

Why should we measure carbon dioxide in a room?

CO2 and indoor air quality

For example, the presence of carbon dioxide in a full room of a school, office or administration is normal. This gas is naturally released by the human body. Because, the more people in a room, the greater the concentration of CO2 in the ambient air and reduces indoor air quality. At the same time, certain activities, such as singing or physical activity, also increase the gas concentration level.

Although this does not depend on the presence of gas, indoor air quality (IAQ) can be conveniently measured by measuring the CO2 concentration in a room . Measuring this gas is the easiest way to understand the air quality in a room and evaluate the quality of ventilation. When the concentration is very high (above 1000 ppm) indoor air is not considered healthy. Then the room should be ventilated (window opening, ventilation, etc.).

Dangers of carbon dioxide

Sınıf, ofis veya toplantı odası gibi yoğun bir kapalı alan doğal olarak bir CO2 konsantrasyonu içerir. Ancak, ortam havasında bu gazın 2000 ppm’den fazla olması durumunda, karbondioksitin sağlık üzerinde anında zararlı etkileri vardır:

Decreased mental abilities (difficulty concentrating and making decisions, etc.)
Physiological disorders (headache, increased respiratory rate, watery eyes, tremors, sweating, etc.)

Therefore, in a closed room Health effects from carbon dioxide and poor air quality are significant . In addition to these reasons, monitoring CO2 in ambient air is also proving useful in the fight against coronavirus.

Against coronavirus: CO2 measurement in a closed area

Covid-19 aerosols and CO2

Covid-19 is transmitted in 3 different ways: by spread of droplets, direct or indirect contact and aerosols. Aerosols are particles that are released into the ambient air when a person breathes or speaks. They are very fine droplets (less than one micron in diameter). of these particles several hours in the ambient air of a room There is a high probability of it hanging. They pose a contamination risk when the person spreading them becomes contaminated with the SARS-CoV-2 virus.

There is a high probability of it hanging. Since humans emit aerosols just as they emit carbon dioxide, the CO2 air quality indicator can be used to determine the presence of pathogens in a room. Therefore, high target gas concentrations pose a contamination risk when a person is contaminated with the SARS-CoV-2 virus. presence of aerosols implies (whether or not it is contaminated with Covid-19).

Carbon dioxide monitoring to reduce the risk of Covid-19

Covid-19 aerosol contamination Health authorities, faced with monitoring ensure good ventilation in occupied rooms advocates and presents it as the first line of defense against the virus. Because CO2 monitoring as an indicator of indoor air quality, determine ventilation needs It is the perfect solution for .

A continuously operating carbon dioxide detector in an occupied area A continuously operating carbon dioxide detector in an occupied area It will help. When the gas concentration becomes too high, the detector signals danger to the occupants of the room (acoustic and/or visual light alarm, depending on the selected device). The room should be ventilated by opening windows, doors or activating a ventilation cycle. Refreshing the air of the room discharging aerosols It will then ensure that the risk of Covid-19 contamination is lower.

CO2 detector for schools, offices and occupied spaces

Many carbon dioxide detectors on the market are extremely complex. Between a portable CO2 detector, a fixed detector, different sensor types and different measuring ranges, choosing, using and maintaining a gas monitor for a classroom, a business, an office or different rooms can be particularly challenging. With a clear need for carbon dioxide monitoring for indoors Faced with each other, two pieces of equipment stand out as efficient solutions: the CO2 detection column on one side and the CO2 sensor for monitoring indoor air quality on the other.

CO2 COVID sensor and air quality analyzer

Easy to use and highly intuitive, the HTRAM CO2 sensor (transmission risk air monitor) monitors indoor air quality by displaying the carbon dioxide level, temperature and relative humidity (hygrometry) in the room.

This air quality analyzer CO2 level It has a display, an integrated audible alarm and a color display (red, yellow, green) to indicate the level of contamination risk. This device is complete, discreet, practical and inexpensive. It runs on batteries for 10 hours (can be charged via USB plug) and can therefore be easily moved from one room to another. This air quality analysis equipment is used to identify contamination risks And It is undoubtedly the preferred ally for ventilating a room, office or classroom.

A CO2 light column

The Werma CO2 detector column is a measuring device in the form of an LED traffic light. Gas concentration in the ambient air in the tower indicated by different LEDs:

LED column signals

LED color	carbon dioxide concentration	Action
Green	less than 1000 ppm
Yellow	Between 1000 and 2000 ppm	ventilation required
Red	more than 2000 ppm	ventilation requirement
flashing red	more than 3000 ppm	ventilation requirement, health risk

Use of this CO2 monitoring device in the context of the Covid-19 pandemic Use of this CO2 monitoring device in the context of the Covid-19 pandemic With infrared CO2 sensor Thanks to this integrated visual warning device, the air renewal quality of a room is easily addressed and Risk of contamination from viruses such as SARS-CoV-2 is reduced . Indoors, the installation of this equipment associated with social distancing, N95 or FFP2 masks, ideally FFP3 masks against Covid-19, will provide maximum protection against the virus.

These equipment are now used in schools , public spaces , local government areas and even used successfully in many public areas such as Covid-19 screening and vaccination centres.

A simple CO2 detector for occupied spaces

The effectiveness of the Werma CO2 detection column depends not only on the simplicity of its bright display. Actually, In order to adapt as best as possible to all audiences and locations affected by the indoor air quality problem, this equipment maximum performance and simplicity Designed for .

CO2 monitoring column, integrated and with pre-calibrated infrared sensor comes together. The device is ready for immediate use, all you have to do is plug it into a regular electrical outlet. Ideally placed in the middle of the room at a height of less than 2 meters, it very clearly shows the constant concentration of carbon dioxide and the need for ventilation when necessary.

This is ready to use for IAQ CO2 monitoring and signaling device occupies the equivalent of a class . Installing several detectors will check the carbon dioxide concentration level in larger areas such as shops, gyms, warehouses or open offices.

Why Are Refrigerant Leaks Detected?

Refrigerant leak detectors Its use makes it possible to protect against refrigerant hazards, while at the same time ensuring the proper operation of equipment, its productivity and reducing the operating costs of cold production facilities. Leak detection, and more generally the control of refrigerants, responds to a variety of challenges in all areas of the refrigeration industry.

Refrigerant leak detection for safety

Danger of leaking refrigerants

There are many refrigerants classified into different types: the former freon CFC and HCFC gases (R12, R123, etc.), the most common HFCs and HFOs (R32, R410a, R1234yf, etc.) and natural refrigerants (CO2, NH3). , hydrocarbons). All these gases used for cold production are dangerous. For refrigerant leak, healthcare and infrastructures potentially hazardous gas concentration levels leads to .

The main dangers of refrigerant leaks are:

Suffocation : Many refrigerants are heavier than air. When a refrigerant leak occurs, gas replaces breathable air in a closed, unventilated space. At certain concentration levels, anyone present is exposed to a variety of health effects that can lead to death by asphyxiation.
Fire and explosion: Some refrigerants, such as ammonia and propane, are flammable and explosive when in contact with an ignition source. The use of pressurized coolers also poses a risk of explosion.

In the face of suffocating, flammable and explosive gases, refrigerant and freon leak detection helps ensure everyone's safety. Monitoring for leaks and the presence of refrigerant gas in air-conditioned environments, near refrigerated racks, refrigerated warehouses, cold rooms, etc. It makes it possible to prevent hazardous exposure of staff, stakeholders, customers, visitors and the public. Installation of refrigerant leak detection systems It also contributes to ensuring the safety of refrigeration plants and infrastructures.

Environmental impact of refrigerant

While natural refrigerants, hydrocarbons (HC) and some HFOs are not very polluting, HFC, CFC and HCFC gases are particularly hazardous to the ozone layer. Environmental impact of refrigerant leaks, This requires monitoring and controlling the use of gases. Leak detection in all refrigeration plants immediately treats gas leaks as soon as they are detected, thus reducing emissions to the atmosphere. helps reduce emissions.

Leaking refrigerant: a loss of efficiency

Any refrigerant leak in the cold production installation, service or production interruption may cause . All refrigeration equipment is designed to operate optimally with a precise refrigerant charge. Underloading caused by refrigerant leaks from the device or the cold circuit immediately leads to malfunction and energy overconsumption. Leakage may also cause potential personal injury.

Low loading of cold production equipment therefore, it may result in a decrease in productivity and a general shutdown of the device, which may result in loss of production or service. Whether it is an air conditioning malfunction or an interruption in the cold system in a warehouse or process plant, the use of a detector or a complete refrigerant detection system provides insight and interfering with upstream makes it possible.

Detect refrigerant leaks to reduce costs

Reduce refrigerant cost

Refrigerant leakage, which is not an unusual occurrence in any circuit, replacement and refilling of refrigerant requires .

These additional operating expenses are not insignificant. On a supermarket scale, on average each year 20% to 25% of refrigerant is lost due to leaks It is estimated.

Considering the price factor (increasingly higher for the most polluting fluids), installing a detection system and a refrigerant leak management protocol provides real financial gains by reducing refrigerant purchases.

Reduce energy consumption

For example, a common situation, especially in the commercial refrigeration industry, is a refrigerant leak in an installation. 10% to 45% more power consumption in cooling equipment is to lead.

Energy overconsumption is not very costly and trivial at the scale of supermarkets, air-conditioned areas or large refrigeration plants.

Control of cold equipment using refrigerant detection devices, both by charging energy excess It ensures both prevention and immediate maintenance of the equipment when a leak is detected.

Compliance with regulations

National and international regulations regulate the use of refrigerants. These regulations aim to control and reduce the environmental impact of these gases. Because, checking for refrigerant leaks It is a necessity in many countries. In France, failure to comply with refrigeration regulations can result in imprisonment of up to 2 years and a fine of 75,000 euros.

In most cases, compliance with these instructions, equipment operation and periodic regulatory leak checks It is facilitated by the use of refrigerant detection systems for .

It is facilitated by the use of refrigerant detection systems for .

Various measuring and monitoring devices make it possible to control the correct operation of refrigeration equipment. In all areas of the refrigeration industry refrigerant leak detection provided by portable gas detectors and fixed installations.

Portable refrigerant leak detectors

Different models of portable gas detectors has . In the context of refrigerant use, the most commonly used portable equipment is leak detectors. These detectors are dedicated to the detection of refrigerants, such as the Tru Pointe IR refrigerant leak detector . They usually include a flexible probe to perform checks and long battery life.

Leak detection, It can also be performed using the PGM IR refrigerant leak analyzer (GD connection), which offers unmatched performance with a 1ppm detection threshold. this device , a refrigerant circuit Ideal for controlling refrigerated racks and installations of all sizes with great precision.

Conventional portable single gas detector natural refrigerants Available for use. A portable CO2 detector is actually used in facilities containing carbon dioxide. PPE (personal protective equipment) olarak kullanılabilir . Bu cihazlar örneğin Covid-19 aşılarının soğutulmuş taşınmasında CO2 tehlikesine karşı kullanılır .

In facilities operating with natural refrigerants and hydrocarbons such as propane, butane, isobutane and ammonia Workers can also be equipped with flammable gas detectors to ensure their safety.

Fixed refrigerant detection systems

A fixed freon detection system Its installation enables continuous monitoring of any cold production facility. Installation of fixed gas detectors is sometimes even meets obligations arising from refrigerant regulations .

Constant detection of refrigerant leaks, It is performed by one or more fixed detectors connected to a gas detection controller. This control unit acts as the brains of the system and triggers alarms as well as servo controls such as ventilation systems and remote alarm signals.

Some fixed equipment, such as the MGS 450 refrigerant detector, can be used as stand-alone equipment. They have an integrated audible and visual alarm signal to alert you in case of danger, without the need for a controller connection.

Regulation: Battery room safety requirements

Securing a battery charging room The regulations set out numerous measures for . The order dated May 29, 2000 and Decree No. 2006-646 dated May 31, 2006 regulate the use of lead-acid batteries. A special battery room is mandatory for charging lead-acid batteries of electric cars and cars with a direct current power of 50 kW onwards. . This regulatory obligation is the first safety requirement against hydrogen emissions, fire and explosion hazards.

Regulations for the charging room also include eyewash, acid holding tank, hazardous area indicator, fire extinguishers, fireproof floor, waterproof coating for dirty water, fire doors and IP55l lighting. It also requires safety design and equipment.

Safety regulations also limit the presence of hydrogen to 1% of the volume of the battery chamber. Requires the presence of mechanical ventilation. In addition to this requirement, in the event of a ventilation failure automatic shutdown of chargers It is mandatory. Finally, there is a button to activate ventilation and stop battery charging urgently. hydrogen measuring unit must exist.

Additionally, to ensure everyone's safety, personnel working in or near the battery room must be authorized to intervene and must be trained on potential hazards.

In compliance with ATEX standards and regulations, a charging room for electric cars must have an ATEX classification (zone 1 or 2). ATEX zoning requires maximum precautions an explosive atmosphere expresses its existence. In logistics, handling or manufacturing environments, a battery room situation with concentrations of hydrogen in the air is a ATEX zone creates .

Minimizing explosion risks All equipment brought and operated in an ATEX classified area must be approved for . Therefore, for example, a battery charging room must be equipped with an ATEX-certified mechanical ventilation and gas detection system.

Dry Ice Danger (CO2 Risk) in the Logistics Chain of the Covid-19 Vaccine

Dry ice and Covid-19 vaccines

New Covid-19 vaccines

After the flu mask, hygiene measures and various containment measures, new Covid-19 vaccines It includes the variety of tools necessary to combat the pandemic. By the end of 2020, after months of development and clinical trials, several vaccines are being approved or are already in use by various national health authorities around the world.

Different Covid-19 vaccine technologies will be available, but some of the first vaccine solutions, including solutions such as the Pfizer-BioNTech vaccine based on Messenger RNA (mRNA), have a common challenge: maintaining storage temperatures. Indeed, to maintain their effectiveness against the virus, some of the vaccines produced to date must be stored down to -70°C or even -80°C. It requires an ultra-low storage temperature.

dry ice cold chain

To maintain the effectiveness of the vaccine To maintain storage at a temperature of -70 °C is a real logistical challenge for manufacturers, carriers and healthcare professionals. This temperature restriction poses a challenge for the organization of mass vaccination policies: vaccination centres, storage centres, hospitals, pharmacies or medical offices. cold chain of the vaccine must be able to protect.

Unlike conventional vaccines, which require a storage temperature as low as -4°C, Covid-19 vaccine serum cannot be stored in medical freezers or conventional refrigerated transport. When faced with this constraint, various solutions are applied: cryogenic units, ultra-cold freezers, transport under nitrogen or kuru buz . Among these solutions, most specialist refrigeration carriers prefer dry ice to guarantee the cold chain throughout the shipment of Covid-19 vaccines.

of dry ice ease of production and its ability to adapt to many environments make this technique particularly effective for storing vaccines. It is also a commonly used technique for storing meal trays in aviation.

Dry ice hazard: CO2

What is dry ice?

Dry ice is simply carbon dioxide (CO2) is the solid state. It is made by compressing CO2 at very low temperature to produce blocks of dry ice or small sticks or granules.

The temperature of dry ice is -78.5ºC . It therefore makes it possible to produce cold very quickly and participate in the maintenance of the cold chain. It is used in various fields such as dry ice cleaning, food and pharmaceutical freezing, IT, chemicals, funeral homes, dermatology, winemaking, fire fighting equipment, refrigerated transportation or even pest control.

CO2 risk in vaccine cold chain

Dry ice, especially in the cold chain of Covid-19 vaccines cooling and protection feature Although it is popular for its reasons, it still carries some dangers.

First of all, dry ice is an extremely cold solid that can cause severe burns. It is a solid that sublimes above -78.5ºC and returns to the gas form carbon dioxide (CO2), a potentially dangerous gas when inhaled.

Colourless, odorless and invisible gaseous carbon dioxide, is a heavy gas that replaces oxygen and therefore a real one in closed spaces. creates a risk of anoxia.

Exposure to carbon dioxide from dry ice

When dry ice is used, carbon dioxide is released in gaseous form, the possibility of exposure of various persons to this gas. Contains . Packers, carriers, warehousers and healthcare system workers in the Codiv-19 vaccine distribution logistics chain are subject to a risk of exposure similar to the CO2 hazard in viticulture, for example.

Almost imperceptible to humans, CO2 gas released in a closed space replaces oxygen. One kilogram of dry ice produces approximately 500 liters of carbon dioxide gas. Depending on the configurations of equipment used to transport and store the Covid-19 vaccine, carbon dioxide concentrations available can have serious effects on the health of staff. Indeed, from a concentration of 1% in air, CO2 causes respiratory distress, at 3% heart rate and respiratory system disturbance, and above 5% unconsciousness which can lead to death. Therefore, the potential exposure of various workers in the dry ice cold chain of the Covid-19 vaccine can be assessed, for example, in ambient air by a portable CO2 detector. It means monitoring CO2 concentrations.

CO2 detector to secure the cold chain of COVID-19 vaccines

Beyond traditional personal protective equipment such as special gloves and safety glasses used when working with dry ice, the Covid-19 vaccine supply chain requires the use of CO2 detection equipment.

Taşınabilir CO2 dedektörü

Since the dry ice cold chain of the COVID-19 vaccine brings together many workers, the ideal safety solution is the use of a portable carbon dioxide detector. Equipment such as the iGas CO2 detector makes it easy and efficient to monitor carbon dioxide concentrations in ambient air. In the event of a dangerous CO2 concentration, the device will alert its user with a strong audible, visual and vibration alarm. Therefore, the provision of a portable detector will ensure the safety of transporters, warehouse workers, doctors, nurses or other people involved in the presence of dry ice.

Fixed CO2 detector

Use of dry ice to preserve the Covid-19 vaccine, Controlling CO2 risk It can also integrate fixed gas detectors for Connected to a gas control unit, a network of fixed detectors or an autonomous fixed CO2 detector, it will ensure the safety of workers in Covid-19 vaccine storage warehouses.

Additionally, the cold chain of the Covid-19 vaccine uses dry ice but also uses other cooling techniques to maintain a very low temperature. Especially in various refrigeration and ultra-cold equipment refrigerants participates in the sanitary logistics chain. Therefore, refrigerant gas leak detectors are essential for the safety and optimal operation of facilities, such as cold stores.

February 2021: New OELs

New OELs come into force in February 2021

Decree numbered 2020-1546 dated December 9, 2020, published in the Official Gazette at the end of 2020, for certain chemical substances. new binding OELs determines . Therefore, the regulation protecting exposed workers is being amended for 9 articles, 5 new OELs are being integrated and will come into force on February 1, 2021.

New binding OELs : wood dust, monomeric vinyl chloride, hexavalent chromium and its compounds, refractory ceramic fibers classified as carcinogenic, silica (quartz, cristobalite and tridymite alveolar dust).
Binding OELs vary : Acrylamide, Bromoethylene, 1,3-butadiene, 1,2-epoxypropane (propylene oxide), formaldehyde, hydrazine, 2-nitropropane, ethylene oxide, o-toluidine.

What are binding OELs?

Occupational exposure limit value (OEL), which determines the maximum exposure level (time-weighted average) to hazardous substances for worker health It is a measure of protection. For some chemicals binding OELs R. 4412-149 of the French Labor Code. It is defined in the article. These safety measures are divided into two exposure periods for certain substances: long term OEL – TWA (during 8 hours of exposure) and short term OEL – STEL (15 minutes of exposure).

Unlike indicative OELs, binding occupational exposure limit values It forces employers to comply with these worker protection measures. Compliance with these regulations, such as gas masks may result in the use of personal respiratory protective equipment. In many cases, these safety requirements also apply to portable, fixed gas detectors or such as the use of reagent tubes. for measuring gases and chemicals It requires the implementation of protocols and solutions .

Compliance with new February 2021 OELs

Gas detection equipment compatibility

Made in OELs on February 1, 2021 As part of these changes, some gas detection equipment uyumlu olması gerekiyor . Whether it is a portable gas detector or a fixed detector, the monitoring device will need to be reconfigured.

For example, for long-term OEL:

The alarm threshold of the formaldehyde detector will drop to 0.3 ppm
The alarm threshold of the hydrazine detector will drop to 0.01 ppm
And the alarm threshold of the ethylene oxide detector will drop to 1 ppm

Where necessary, a combination of gas controllers , fixed transmitters and portable gas monitoring devices with software update together restructuring will be required. Finally, relevant portable devices and fixed gas detectors must be recalibrated following the February 1, 2021 OEL change.

For some lines of connected equipment, such as Blackline Safety gas detectors, threshold changes can be made remotely for the brand's entire fleet of devices in a few clicks, without going to a calibration station.

Reminder about respiratory protection and OELs

The new OELs provide, first of all, a reminder of the dangerousness of exposure to these substances, and secondly, they provide a reminder to all stakeholders to deal with these hazards. Reminds us that respiratory protection solutions are available. By treating OEL compliance as a minimum prevention goal, many measures can be taken to minimize risks. Preventive measures should be taken . With this in mind, teams can be provided with a variety of respiratory protection equipment to improve safety levels.

Therefore, February 2021 will be included in the new OEL list. When we look at it, we can see that wearing a dust mask provides additional protection against the dangers of exposure to silica and wood dust.

Similarly, the use of a gas mask, whether a half mask or a full face mask, can better deal with the danger of substances affected by OEL changes. However, choosing the right gas mask filter is essential. For example, this would include using a class P3 filter for maximum filtration protection against dusts (wood, silica), using a type AX filter for protection against ethylene oxide, and using a type K gas filter for protection against formaldehyde and hydrazine. Wearing a powered air-purifying respirator using the appropriate filter will provide more comfortable filtering protection (breathing effort on the filter is made by the machine, not its user).

Finally, occupational exposure limits set by law Beyond all supplied air breathing apparatus solutions allow workers to work in contaminated atmospheres well beyond the OEL. In an area contaminated above the OEL, the use of a supplied air respirator will provide breathing air from a completely independent source. Likewise, wearing a SCBA (self-contained breathing apparatus) will completely isolate its wearer from polluted air thanks to the breathing air cylinder attached to the respiratory protection mask.

FFP2 Mask against coronavirus

At the beginning of 2021, FFP2 mask is becoming increasingly popular in the fight against the spread of Covid-19 . This air-purifying respiratory protective equipment that provides a high level of protection is still not well known to the general public. We are evaluating this type of mask and its use in the face of the coronavirus outbreak.

Covid-19 and FFP2 mask

Faced with Covid-19 and its more contagious variants, health authorities in different countries have taken action to limit the increased risk of transmission. FFP2 leans towards wearing masks. In Austria, they have now become mandatory in transportation, shops and service places. Germany has also made wearing this type of protective mask mandatory.

In France, the Supreme Council of Public Health recommends the wearing of high-performance category 1 disposable masks (according to standard EN 14683) for the general public. At the same time, HCPH recommends that the FFP2 mask be used only for healthcare personnel performing invasive procedures and performing manipulations of the respiratory tract.

What is an FFP2 mask?

Surgical mask VS FFP2 mask

FFP2 mask in combating the Sars-CoV-2 epidemic To understand why it is popular, it is necessary to understand the difference between a surgical mask and respiratory protective masks in the FFP category.

Surgical masks that meet the NF EN 14683 standard are, as the name suggests, primarily designed for medical use. Depending on their type (I, II or IIR), they prevent the spread of droplets but they do not prevent inhalation of aerosols (very fine particles suspended in the air). However, through aerosols Risk of infection with Covid-19 It is important. It is one of three modes of transmission of Sars-CoV-2 (others include: contact with respiratory droplets, respiratory secretions, coughing and sneezing, and contact with an infected person or surface).

Respiratory protection masks classified as FFP according to NF EN 149 standard, It is designed to protect against the finest particles found in the ambient air, especially aerosols. They are therefore currently valuable to prevent Covid-19 contamination as much as possible.

FFP2 protection

Designed with multi-layer innovative filtering materials disposable FFP2 masks It is easy to use, affordable and provides protection against viral particles such as Covid-19.

FFP2 mask with an infiltration rate of less than 8% It is a respiratory protection that filters at least 94% of aerosols. It is a respiratory protection mask that is widely used in many environments and complies with the NF EN 149 standard ( American N95 mask or similar to KN95 for South Korea). Outside of the medical environment, this PPE (personal protective equipment) is used in various industries for woodworking, metalworking or waste disposal. Indeed, FFP2 protection provides a high level of security against various elements such as droplets and aerosols from very fine wood, metal particles, welding fumes, paint, varnish and viruses.

FFP (For Filtering Face Particles) protection are available as disposable masks but are also available as gas mask filters. For example, combination filter cartridges such as A2-P3 protect against organic and inorganic gases and vapors and solid and liquid microparticles with boiling points above 65°.

Contrary to popular belief, a FFP2 PPE does not always take the form of a duckbill mask . In fact, the FFP2 qualification depends not on its shape, but on the level of protection against particles and aerosols. The FFP2 level of protection can be attributed to many types and forms of equipment. A duckbill, shell, medical, consumer, disposable, reusable or dustproof mask can achieve this qualification. The same applies to other filtered respiratory protection equipment, such as full gas masks or powered air-purifying respirators, which can be equipped with anti-particle protection filters up to FFP3 level.

Some FFP2 masks can be equipped with an exhalation valve . Wearing non-powered air cleaning (filtering) respiratory protective equipment requires a respiratory effort proportional to the level of protection of the equipment. Therefore, a valveless FFP2 mask contains resistance during inhalation and exhalation. No matter which mask shape you choose, the exhalation valve will allow exhaled air to escape more easily. Therefore, this PPE with valve provides great comfort to the user . For this reason, respiratory protection with integrated valves is generally more popular for tough jobs (sanding, spray painting, etc.).

Which FFP2 mask for Covid-19 protection?

To optimize the use of this PPE, which is important for optimal protection against Covid-19 is to choose a mask shape that fits the face properly. At the same time, for maximum protection disposable FFP2 masks should be preferred and replaced regularly.
Finally, wearing valved PPE provides genuine comfort and remains an effective protection solution for the wearer, but is likely to allow aerosols emitted by the wearer to escape into the ambient air.

Should I choose FFP3 mask?

FFP3 mask, Provides respiratory protection that filters at least 99% of aerosol with less than 2% inward leakage. This type of equipment is maximum protection level creates . The use of an FFP3 mask as protection against respiratory Covid-19 contamination may seem relevant or even necessary in certain situations. However, installing this type of protection often has a significant respiratory effort It is important to remember that it is subject to Therefore, it is often difficult to wear this equipment all day without feeling uncomfortable. To solve this problem of breathing resistance when wearing an FFP3 mask, some manufacturers are expanding their research efforts and offering increasingly comfortable equipment. For example, filtration specialist GVS, with minimal breathing resistance developed the F31000 FFP3 mask, which provides maximum protection. The same goes for the manufacturer Dräger, which optimizes protection and comfort with the CoolSAFE filtration technology of its X-plore 1900 dust mask.

It should also be noted that the selected respiratory protection mask should be worn and used in accordance with the recommendations of health authorities. Whether it is a surgical, FFP2, FFP3 mask or a traditional gas mask there are many precautions that need to be taken. Moreover, while essential for optimum protection, correct fit of the mask on the face is still too often neglected.

CO2 Danger in Bars and Restaurants

Little known to the public and professionals, used in beer dispensers and carbonation machines dangers of carbon dioxide is often underestimated. In fact, restaurants, bars and breweries are constantly CO2 tanks for serving draft beer and soft drinks stocks . Inhalation of high CO2 concentrations accumulated in closed spaces where gas cylinders are located causes many sudden accidental deaths every year.

Carbon dioxide in bars and restaurants

CO2 and beer

Beer, very commonly consumed in bars and restaurants, is a carbonated beverage that contains carbon dioxide. In alcoholic beverages such as champagne, cider or beer, natural fermentation is what produces the CO2 in the beverage. Once in the drink, the goal is to not allow the customer to escape until they consume it. beer tap And CO2 filling This is exactly where it comes into play.

Although beer is the oldest man-made beverage in the world, the beer tap was only invented at the end of the 18th century. The first beer taps were manual. You had to pump to see the beer come out. Nowadays they are cooled and pressurized.

The working principle of the system is simple: carbon dioxide (or more rarely nitrogen) is stored in a cylinder and passes through a pump to get to a pressurized vat. So when you turn on the tap, beer gushes out, driven by CO2. The liquid leaving the keg is immediately replaced with CO2 and the beer loses no gas.

CO2 and soft drinks

In catering, bars and other drinking establishments, venues are often with a professional carbonation machine is equipped. This equipment is also known as carbonated water machine or carbonated drink dispenser. They enable mixing (syrup/water) and carbon dioxide They include it to make sparkling sodas or sparkling water.

A professional mineral water machine, a water inlet, a syrup dispenser (if available) and a food grade CO2 cylinder It works with . Practical, economical and easy to use, this equipment can be found in many fast food establishments, bars and restaurants of all sizes.

CO2 cylinder: Risk of gas in restaurants and bars

Food grade CO2 cylinder: storage and use

In bars and restaurants, the use of a professional beer tap or carbonation machine requires the addition of carbon dioxide. This additive is suitable for 2 to 10 kg , a food-grade CO2 tank that may or may not be refillable It is made by . A 10kg CO2 tank can serve 70 kegs of beer or 2,100 liters of soft drinks.

While CO2 cylinders are common in bars, breweries, and restaurants, the danger they pose is not obvious to most managers and stakeholders in drinking establishments. Indeed, equipment failure, poor maintenance or misuse of these cylinders can cause serious damage to all those involved in the business. may cause a serious risk.

For all restaurants and bars Storage of CO2 cylinders The question arises. We often observe improper storage in cellars, sheds, reserves or poorly ventilated rooms (especially likely to be confined spaces prone to gas accidents).

CO2 crash in bars and restaurants

worldwide in breweries, bars and restaurants CO2 accidents due to carbon dioxide are very common. Unfortunately, many fatal accidents occur every year.

For example, in a cellar of 4 × 3 meters A 10 kg carbon dioxide cylinder if completely discharged, this would result in a CO2 concentration of over 16% by volume in the room. Like refrigerants, carbon dioxide is a gas that fills a volume by replacing oxygen. Because risk of drowning, is the main danger associated with the use of food grade CO2 cylinders. Stocks in bars and restaurants are particularly prone to this risk, but accidents can also occur when carbonation machines and beer taps malfunction or tanks are used improperly, causing CO2 leaks. may come .

CO2 danger in restaurants and bars

A CO2 leak can lead to a particularly dangerous concentration of the gas for everyone in the facility. Indeed, carbon dioxide is an odorless, colorless and mostly harmless gas when at normal concentrations (0.03%) in the air, but at higher concentrations it very quickly becomes dangerous.

CO2 detection in bars and restaurants

The use of CO2 cylinders requires taking into account its risk. Avoid CO2 hazards in bars, brasseries or restaurants Various measures must be implemented to ensure maximum protection against

Firstly, these CO2 cylinders should be stored in a well-ventilated room to avoid any accidental carbon dioxide accumulation. Secondly, in the ambient air Monitoring the CO2 level.

Fixed CO2 detector in bars and restaurants

In a bar or restaurant, the installation of a fixed CO2 detector is the optimal solution to protect people who may be exposed to very high concentrations of this gas. A fixed gas detector such as the MGS450-CO2 will be ideally placed in the cylinder storage area (vaults, reserves, etc.).

It is a security solution that will protect the place 24/7. Sound and light signaling integrated into the control unit will warn the user before he or she is in danger.

Portable CO2 detector in restaurants and bars

Besides the installation of a fixed gas detector, the use of a portable CO2 detector is an interesting alternative for monitoring carbon dioxide concentrations in drinking water utilities.

This personal protective equipment will keep its user safe when changing CO2 cylinders or doing any work on the beer dispenser or beverage machine. Using a portable gas detector will provide real-time measurement of CO2 exposure and provide an accurate indication of the carbon dioxide concentration in the room.

Many portable CO2 detectors with different advantages may be suitable, such as the small, inconspicuous and very popular iGas CO2 single gas detector or the X-am 5600 multi-gas detector which can monitor 6 gases simultaneously.
