In a situation where dangerous chemicals are released into the air, a gas mask can protect you from them. A gas mask is a breathing device that includes a tight-fitting facepiece and filter cartridges attached to it via straps. A protective hood may be included in some models. The filters clean the air and do not add oxygen (unless connected to an oxygen tank).
A person wears a gas mask by putting it over their head and sealing it tightly around their mouth, nose, and ears with the straps. It is important to make a good seal because it is through this that harmful substances can be drawn in. It is also important that the user follows all instructions and cautions carefully.
There are several types of filters for a gas mask, and each type of filter offers protection against different chemical or biological hazards. The filter type must match the hazard to be counteracted. For example, there are no all-purpose filters for chlorine or mustard gases, which are different from each other. Moreover, the mask and filters can be used only when the person is wearing protective clothing and is in a room that is not open to the outside environment.
In addition to chemical agents, some gas masks are designed for use against biological and particulate substances. Airborne toxic materials can either be gases or particles, and both need to be neutralized with the correct filter. Biological filters require specific bacteria to be effective, while particle filters are often made with activated carbon.
Gas masks have a long history and were originally developed to protect miners working in the vicinity of volcanoes and from other sources of poisonous air, such as carbon monoxide and smoke. More advanced models were developed during World War II, and the United States military still issues them to its troops today.
Some military-grade gas masks offer features that are not found on civilian-grade options. For example, some feature a bayonet connection that makes it easy to attach the filter canister and provides a stronger fit. They are also built to resist dirt, aging, fogging, and scratches. These features are especially important for people who will be wearing the mask for extended periods of time.
