Tips: How to use a gas mask to know the protective effect?

We all know that wearing gas masks can prevent the inhalation of toxic gases. How can gas masks protect against colorless and odorless gas? Will wearing gas masks inhale toxic gas? To help everyone better understand gas masks and feel gas masks? The protective effect, Xiao Bian today introduced the experience of the protective effect of gas masks.

The basic point of using gas masks is to ensure airtightness. Therefore, to feel the protective effect of gas masks, we must feel the airtightness of gas masks. After wearing masks, block the entrance of gas masks by hand. Then breathe to see if you can breathe in air. This is how gas masks are tested for airtightness. Once you have determined that there is no problem with airtightness, you can use gas masks to get into the gas environment.

In the use of gas masks in hazardous environments, we need to pay attention to the protection time of the filter parts. Due to different environments, the time for protection of the filter parts is also different. During use, gas masks with good protective effect will not smell odors. Breathing smoothly, if it feels that the respiratory resistance increases, it means that the toxic components have absorbed quite a lot of toxic gas components and the protective effect is reduced. At this moment, we must immediately withdraw from the working environment.

In general, gas masks with poor protection have poor air tightness. The protection time will also be very short, and even unable to provide effective protection, therefore, we must choose the regular qualified products for everyone to purchase gas masks.
