Q & A of knowledge points before selecting gas masks

Often in the process of providing technical support for gas mask products for customers, customers will repeatedly ask questions about the knowledge of gas masks, and sort out a few points for your reference:

the following questions and answers effectively provide users with the relevant help information when choosing gas masks and escape masks

Q: can everyone wear gas masks and respiratory protective equipment

A: it is more difficult to breathe through respiratory protective equipment than in open space. People with lung diseases, such as emphysema, asthma, or the elderly, will have some difficulties. Some people with claustrophobia are also unable to wear masks or headscarves. People with vision problems will be affected when wearing masks or headscarves (some masks can be used by people wearing glasses)

Q: can we expect to protect ourselves from any possible danger by purchasing gas masks or escape masks

A: these respiratory protective equipment can only be used for protection against certain threats. 1t is necessary to strictly abide by the precautions, use limits and restrictive requirements provided with respiratory protective equipment. 1f the mask can’t form a tight fit with your face, there will be pollutants leaking in the air. Any condition affecting the fit of face and mask, such as beard or sideburns, will cause leakage. There are different styles and sizes of masks, which are different from people with different face shapes. When receiving training, it is necessary to correctly understand the methods of wearing and using gas masks

Q: can gas masks protect children

A: there are many problems when children use respiratory protective equipment, especially for infants. For example, the existing masks are not suitable for infants. Anyone who uses respiratory protective equipment needs to have a mask suitability test and be trained in proper use and maintenance

Q: for a specific hazard, if 1 have suitable filter elements and gas masks, can they permanently protect me from environmental hazards

A: gas masks and escape masks reduce the exposure of harmful substances through filtration. However, if the concentration of harmful substances is very high and exceeds the capacity of the filter element (either because the amount of harmful gases or particles exceeds the design capacity of the filter element, or because you stay in a dangerous environment for longer than the designed service time), the exposure of harmful substances will be reduced, 1n these cases, they do not provide the protection required. 1n addition, even if the test can prove that the mask is suitable for your face shape, it does not mean that there is absolutely no leakage. When the concentration of harmful substances is extremely high, even a small amount of leakage can be fatal

Q: can the filter box and mask last a lifetime

A: filter box, filter material and mask will be aged. The life of the filter box is limited. 1f the filter element on the mask has expired, or has been opened or damaged, you will not be protected. Filter boxes and tanks containing activated carbon and chemical reagents must be stored under sealed conditions. 1f they have been opened or not stored under airtight conditions, they should not be used. Even if there is the original packaging, the validity period on the packaging should be verified before purchasing. 1n addition, the mask will age over time. Respiratory protective equipment must be stored in a clean and dry environment, avoid over cooling and overheating, and check according to the manufacturer’s recommendations

Q: if the gas mask is used correctly, will 1 be 100% safe

A: the filter element can only filter some substances in the air, and some harmful substances can enter the body through the skin. For such harmful substances, the gas mask or escape mask must be combined with protective clothing, protective gloves and other personal protective equipment, and the protection is effective

Q: can a gas mask protect me if there is a lack of oxygen in the air< A: gas masks don't produce oxygen. 1n the environment of insufficient oxygen concentration, such as fire, oil tanker and other confined space, there will be the risk of suffocation Q: can a gas mask protect me in case of fire A: if your main concern is how to escape from a smoky building, it is very important to read the information provided by the manufacturer carefully. Smoke particles may quickly block the filter box on the gas mask. 1n addition, the filter box used should have the function of protecting carbon monoxide and special chemicals at the scene of fire. Not all escape masks can provide such protection. There are many gas masks and escape masks, and some of the components on them, including headgear and mask, will melt in the fire Q: once you wear a gas mask or escape mask, how long can it last A: it depends on the capacity of the filter element and the amount of harmful substances in the air – the higher the concentration of harmful substances in the air, the shorter the service life of the filter element, so there is no absolute time limit, which will vary with the capacity of each kind of respiratory protective equipment. This is why in the emergency escape plan, we should consider how to reach the safe area before the filter element fails Q: can respiratory protective equipment really protect my safety as recommended by the manufacturer A: in the United States, N1OSH will be responsible for the inspection and certification of respiratory protective equipment used by workers to protect hazardous substances in workplaces. N1OSH Certified Respiratory protective equipment will be marked with “N1OSH certification”, and N1OSH certification number will also be provided. However, N1OSH certification is only for some specific hazards, so even if there is certification, it is not suitable for all hazards. N1OSH certified products are provided with a “certification label” indicating the applicable protection object. When purchasing respiratory protective equipment, you should check the certification label to make sure that the certification protection you get is the protection you need this article is a reprint of 1nternet media, which only represents the author’s point of view and has nothing to do with this website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
