Filtering respiratory protection devices<\/strong>\u00a0Its efficiency\u00a0mainly depends on the choice of filter that monitors the gases, vapors and particles present. Depending on the activity sectors and the gases that are likely to be present there, different\u00a0gas mask filters<\/strong>\u00a0Provides effective respiratory protection:\u00a0particle filters<\/strong>\u00a0(fine dust, aerosols, viruses and bacteria),\u00a0anti-gas filters<\/strong>\u00a0(organic and inorganic vapors, acids, ammonia and mercury vapors),\u00a0combined filters<\/strong>\u00a0(gas and particles),\u00a0CO\/NO filters<\/strong>\u00a0And\u00a0Reactor \/ Nuclear filters<\/strong>\u00a0(Iodine 131 and radioactive methyl iodide).<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Gas filters<\/h3>\n
\n

There are different types of gas mask filters for each category of gas mask and depending on the nature of the\u00a0gases or vapors. Each breathing cartridge is labeled with a letter and a specific color for each gas or gas family in accordance with the European standard EN 14687.<\/p>\n

Gas mask filter categories:<\/h3>\n
\n

Air purification respiratory filters are grouped according to efficiency categories according to EN143 and EN143\/A1 standards.<\/p>\n

Maximum allowable concentrations of toxic substances:<\/p>\n

\u2013 Half mask respirator: 50 times OEL<\/p>\n

\u2013 Full face mask respirator: 2000 times OEL<\/p>\n

Class 1 (lower efficiency): Canister filter (e.g. A1) \u2013 small capacity, gas content below 0.1% by volume<\/p>\n

Class 2: Cartridge filter (e.g. ABEK2) \u2013 medium capacity, gas content below 0.5% volume<\/p>\n

Class 3:\u00a0%<\/strong>\u00a0For a gas ratio of less than 1 volume<\/p>\n

Particle filter<\/h3>\n

There are different particle filter classes for gas mask filters:<\/p>\n

\u2013 P1 class filters \u2013 low efficiency, this stops at least 80% of the aerosol (under 20% penetration)<\/p>\n

\u2013 Class P2 filters \u2013 medium efficiency, intercepting at least 94% of this aerosol (under 6% penetration)<\/p>\n

\u2013 P3 class filters \u2013 high efficiency, stops at least 99.95% of this aerosol (under 0.05% penetration)<\/p>\n<\/div>\n

Combined filters (gas and particulate)<\/h3>\n
\n

As the name suggests,\u00a0combined gas mask filter both\u00a0<\/strong>gases<\/strong>\u00a0It also stops particles. These filtered breathing cartridges are heavier but more efficient than aerosol or gas cartridges. Air first enters through a particle filter (also a pre-filter) and then passes through a gas filter.<\/p>\n

Combined gas and particle filters also provide safety against paint droplets and gases. These respiratory protective cartridges are mostly used in liquid spraying jobs.<\/p>\n<\/div>\n

Air filtering respirator usage limits<\/h2>\n
\n

Never use filtered respiratory personal protective equipment in the following situations:<\/strong><\/p>\n

\u2013 Ambient oxygen rate is below 19%<\/p>\n

\u2013 In closed areas or places with poor ventilation: tanks, tunnels, boat docks\u2026<\/p>\n

\u2013 If the substance concentration is unknown or directly hazardous to life or health (IDLH)<\/p>\n

\u2013 When the substance concentration exceeds the permissible concentration or filter capacity<\/p>\n
