What are the problems that can not be ignored by using gas masks?
First of all, when we buy gas masks (HAIGU), we must make clear the nature, concentration and oxygen content of the air in the operating environment. We should not buy blindly until the environment conditions are clear. Depending on the type of protection, to see whether it meets the requirements of the operating environment. There are many kinds of gas masks, some of which have the function of dust protection, some of them only have the efficacy of anti gas, and do not consider the use of environmental needs, and use gas masks indiscriminately, so that they can not play an effective role in security protection. There are gas masks, filter parts are protected by different types, different filter parts, shielding gas types are different, according to the actual situation to choose.
Finally, we need to pay attention to how to wear gas masks. The gas mask and not to head a so simple, must read the instructions carefully before operation, according to the method of wear operation, carefully check the tightness of the mask is good, if there is damage, to prevent poisoning work.
Second, the use date of the filter. The filter piece is the core component of the gas mask, and the function of the gas mask is mainly reflected in the filter piece. Once the filter is invalid, the gas mask will be meaningless. Therefore, we must pay attention to the timely replacement of invalid filter parts, and then pay attention to the proper maintenance of filter parts.
In addition, it should be noted that when the concentration of gas is greater than the specified range of use or the oxygen content in the air is less than 18%, no self absorption filter respirator (or respirator) can be used. Direct gas masks provide tolerance to toxic gas with a volume concentration greater than 0.5%.
