Mask cleaning with disinfectant wipes

At least, mask cleaning It can be done using a solution of water and a non-aggressive detergent (according to the manufacturer's recommendations) or appropriate disinfectant wipes. However, this practice has some disadvantages: it requires close attention to the expiratory valves and mask sealing, but above all it does not guarantee complete disinfection in every corner of the mask.

Good mask cleaning practices

Good practice for cleaning PPE masks, which are more complex to apply, involves several steps, ranging from high water washing to bagging the mask after washing and disinfection. After the mask is washed with a large amount of water, it is placed in a special washing machine using a special cleaning and disinfection product with a suitable temperature program for perfect cleaning and hygiene. It is then dried at temperature to ensure the elimination of any germs or bacteria. After drying, it is individually sealed and packaged, proving that it is healthy and suitable for use.

Banning practices

Some reflexes and unwise advice encourage cleaning techniques that can damage a PPE mask, such as using aggressive detergents, talcum powder or glass cleaning products for the visor. These products should be avoided because they pose risks of dermal transmission, inhalation, and material degradation. If the mask is being washed by hand, it is important to proceed gently to avoid damaging fragile elements of the mask such as the sealing skirt, panoramic visor, exhalation valve or phonic membrane.

Also note that gas mask filters cannot be cleaned, a passage through water will render them unusable. don't forget .

The decree of 19 March 1993 requires periodic inspection and control of category III PPE by an approved maintenance center once a year to verify their proper functioning.
