How to clean industrial protective masks?

There are various types of industrial protective masks, and the selection must be based on different job requirements and working conditions.

　　
The outer layer of industrial protective masks often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt on the outer layer will be directly contaminated. It becomes a source of infection by inhaling the body when close to the face. When the mask is not worn, it should be folded into a clean envelope, and the side close to the nose and mouth should be folded inward. Don't just put it in your pocket or hang it around your neck.
　　
If industrial protective masks are moistened by exhaled heat or saliva, their effectiveness in blocking germs will be greatly reduced. Therefore, as many masks as possible should be prepared for replacement. They should be changed and washed once a day. When washing, it should be scalded with boiling water for 5 minutes.
　　
Industrial protective masks should be cleaned and disinfected every day. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:
　　
Clean. First rub the gauze mask gently with warm water and soap. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then rinsed with clean water. Please be careful not to rub it hard, because if the warp and weft gap of the gauze is too large, it will lose its anti-dropping effect.
　　
disinfect. Soak the cleaned mask in a 2% peroxy-2 acid solution for 30 minutes or boil it in boiling water for 20 minutes or steam it in a steamer for 15 minutes, and then dry it for later use. This method is suitable for gauze masks and bowl-shaped masks.
　　
examine. Before using again, you should carefully check whether the masks and face shields are still intact. For gauze masks and face shields, you can take the light transmission inspection method, that is, take the light in front of the lamp to see if there are obvious light spots. Is the rate consistent? If in doubt, replace it with a new one. In any case, face masks and masks are usually updated after 3 to 7 cleanings, and masks of particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to regular replacement of the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it must be replaced after 7 to 14 days. This type of mask cannot be reused after cleaning.
