Factory talks about how to clean air respirator

Air respirators, also known as gas-filled gas masks, are sometimes referred to as fire masks. It uses a compressed gas cylinder as the source of gas, but the cylinder contains compressed air. Widely used in fire protection, chemical, shipbuilding, petroleum, smelting, warehouse, laboratory, mining and other departments, for firefighters or emergency ambulance personnel to safely and effectively extinguish fire in various environments such as smoke, poison gas, steam or oxygen deficiency. Rescue and relief work.

How to clean the air breathing apparatus?

The outer layer of the air purifying respirator often accumulates a lot of dust, bacteria and other pollutants in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the outer layer contaminated dirt will be Inhaled directly to the face, and become a source of infection. When the mask is not worn, it should be folded into a clean envelope and folded close to the side of the nose and mouth. Do not hang it in the pocket or hang it around your neck.

If the air purifying respirator is wetted by the exhaled hot air or saliva, its role in blocking the pathogen will be greatly reduced. Therefore, usually a few masks are usually prepared for replacement, and should be changed once a day. Wash with boiling water for 5 minutes.

Air-purifying respirators should be cleaned and disinfected daily. Both gauze masks and air filter masks can be sterilized by heating. The specific approach is:

1. Cleaning. Gently lick the gauze mask with warm water and soap. The bowl-shaped mask can be gently brushed with a soft brush and then washed with water. Please note that you should never use force, because if the latitude and longitude gap of the gauze is too large, the effect of anti-stopping droplets will be lost.

2. Disinfection. Place the cleaned mask in a 2% peracetic acid solution for 30 minutes or boil in boiling water for 20 minutes or in a steamer for 15 minutes, then allow to dry. This method is suitable for gauze masks and bowl masks.

3. Check. Before using it again, you should carefully check whether the mask and mask are still intact. For the gauze mask and mask, you can take the light transmission method, that is, take the light before the light to see if there is any obvious light spot, and the middle part and the edge part are transparent. Is the rate consistent? If there is any doubt, it is necessary to replace it with a new one. In any case, masks and masks are generally updated after 3 to 7 washes, and masks of exceptional quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to the regular replacement of the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it should be replaced after 7 to 14 days. This mask can not be used after cleaning.
