How to use a smoke mask

In general, few people use smoke masks in daily life, but people in special positions, such as those who come into contact with chemicals or firefighters, may often use smoke masks. But you should pay attention to and understand the correct way to use smoke masks? Then we will give you a detailed introduction below. We hope that after understanding these methods, you will have a correct grasp of the use of this mask.

1. When using a mask, wear it from the chin upwards, adjust the headband appropriately, put on the mask, block the air inlet of the filter box with your palm and inhale hard. If the mask fits tightly against the face without leakage, the mask is airtight and you can work in dangerous drug-related areas;

2. After using the mask, wipe off sweat and dirt from all parts, especially the lens, exhalation valve, and inhalation valve. If necessary, rinse the mask with water and clean the gas filter box.

3. If used in areas with infectious viruses, the mask and filter cartridge can be wiped with 1% peracetic acid disinfectant, but the filter cartridge cannot be soaked or put into water to prevent it from becoming ineffective. And after disinfection with disinfectant, it should be wiped with clean water and dried before use;

4. Before using the mask, you should first check whether all parts of the mask are intact, whether the breathing valve piece and the bottom of the breathing valve are sealed, whether the filter box is tightly connected to the main body, and whether the filter material in the filter box is loose. The mask must be worn straight, covering the mouth and nose, with no gaps on either side of the nose. The mask straps must be fastened securely and adjusted so that the mask is not loose, does not squeeze the face and nose, and does not leak air.

The above is a method and technique for using smoke masks. I hope everyone has a more comprehensive understanding of this common sense. Although we may not use it often in our lives, when you know these usage methods, you will not be in a panic in an emergency.
