The outer layer of industrial dust masks often accumulate a lot of dust, bacteria and other dirt in the outside air, and the inner layer blocks the exhaled bacteria and saliva. Inhaled into the human body when directly touching the face, and become a source of infection. When the mask is not worn, it should be folded into a clean envelope, and the side close to the nose and nose should be folded inwards. Do not stuff it into your pocket or hang it around your neck.
If the industrial dust mask is wetted by exhaled heat or saliva, its effect of blocking germs will be greatly reduced. Therefore, you should prepare as many masks as possible for replacement. You should change and wash it once a day. When washing, it should be scalded with boiling water for 5 minutes.
Industrial dust masks should insist on daily cleaning and disinfection. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:
1. Cleaning. First, gently rub the gauze mask with warm water and soap. The bowl-shaped mask can be gently brushed with a soft brush dipped in detergent, and then the user can wash it off with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing the droplets.
2. Disinfect. Put the cleaned mask in a 2% peracetic acid solution for 30 minutes or boil in boiling water for 20 minutes or steam in a steamer for 15 minutes, then dry it for use. This method is used for gauze masks and bowl masks.
3. Check. Before using it again, you should carefully check whether the masks and masks are still intact. For gauze masks and masks, you can take a light transmission inspection method, that is, take a look 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, masks and masks are generally replaced with new ones after 3 to 7 times of cleaning. Masks of particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to regularly replace the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it will be replaced after 7 to 14 days. This mask cannot be cleaned and then reused.
