Gas Masks and Filters
By Ross Bainbridge Gas masks and filters are used to protect the body from the harmful affects of chemical and biological agents. Many chemicals like chlorine, hydrogen cyanide, phosgene, mustard agent and others were used during World War I. These caused a number of causalities among allied forces and created the need for protective masks. Since then gas masks have evolved and protect against all types of known chemical and biological agents. Gas masks use different techniques to protect the user. But the common components like face piece, hood, eyepieces and filters are present in almost all masks. The most basic mask uses the filtration technique. Pollutants generally have larger particles than oxygen and by using a fine mesh these can be kept out. The only drawback is that air supply is also restricted in this process. The other process uses the absorbing qualities of certain chemicals such as activated charcoal to control the harmful agents. Such masks have limited use, as they are able to absorb only a few chemicals. The present day masks use the method of chemical neutralization. These masks contain chemical filters that neutralize the harmful chemicals present in the air. Some of these also have tubes for drinking water, communication system and winterization kits to prevent fogging during cold weather conditions. These masks provide adequate protection only to the face and internal organs. Chemicals have now been developed that affect the skin and may be used in future terror attacks and war zones. A protective body suit attached to the mask is a good option to counter the harmful affects of such chemicals. Chemical and biological agents have been used in the past and will be used again. The armed forces, along with other researchers, are working together to improve the quality of existing masks and develop new protection systems. This will help them operate in troubled areas without risking their lives. Gas Mask provides detailed information on Gas Masks, Military Gas Masks, Surplus Gas Masks, Gas Masks For Sale and more.
