A gas mask is a protective breathing device that filters out airborne toxic chemicals and smoke particles. This type of equipment is often used by military personnel and first responders who must enter hazardous environments that can be filled with toxic gases or dangerous particulates.
A mask is worn over the nose and mouth, and it consists of an elastic polymer with adjustable straps that fit over a variety of facial sizes. There are also various filters that can be connected to the mask to remove harmful contaminants from the air that is drawn in when the wearer inhales.
The mask is often attached to a canister that contains the filter and a supply of oxygen. There are also other types of respirators that require a connection to a pressurized tank of oxygen that the wearer must breathe through via hoses. Some of these devices are used in mining or other industries, while others are designed to provide protection for civilians in a hazardous environment.
When properly maintained and used, a gas mask can provide effective protection against toxic chemicals and smoke. However, it is important to understand the limitations of a gas mask before you purchase one for your own use.
A basic model that resembles the modern design of a respirator was invented in 1847 by Lewis Phectic Haslett, according to the website First Facts. His early prototype allowed for inhalation through a mouthpiece and outflow of air through a vent. His invention was a forerunner of the gas mask that was developed in 1916 by Edward Harrison, Bertram Lambert and John Sadd. This large box respirator was issued to troops in February and August of that year.

Although some older gas masks contained chrysotile or crocidolite asbestos, most modern models do not contain this substance. However, they should still be kept in a clean and dry place, away from extreme heat or cold, to ensure they continue to work as intended. They should also be regularly inspected to make sure there are no tears or holes in the filter and that the sealing rings are intact. Eventually, any of these components may need to be replaced. A gas mask should not be used if the filter or sealing rings have been exposed to chemicals, are no longer in good condition or if they have a leak. For these reasons, it is important to maintain your gas mask and replace its filters regularly.
