What You Should Know About Gas Masks
It is natural that with the threat of biological or chemical terrorism comes a lot of talk about gas masks. Before making the decision to buy and use a gas mask it is important to understand the technology behind the different types of available equipment.
It is also important to understand that a gas mask alone will not give adequate protection from biological or chemical contamination. Even the use of a protective suit will only give some protection from airborne contaminants. Contact us to buy masks and protective suits.
The least effective type of gas mask is known as a half-mask air-purifying respirator. These cover the nose and mouth allowing the user to breathe through the filtration system of the mask. However, many chemical and biological agents use the eyes as an entry point, causing contamination.
A more effective type of mask is known as a full-face air-purifying respirator. These Gas masks provide a clear face mask or clear eye pieces that protect the eyes, as well as the nose and mouth. The issue with these air-purifying respirators is that they may leak from either a poor fit or from a crack or hole on the mask.
Anyone considering using this type of gas mask should consider that the constant flow of air through the filter means that the filter needs more frequent replacement.
