Meaning:
A gas mask is a protective device worn over the head and face to prevent the inhalation of gases, vapors, or particulate matter from the surrounding environment. It is typically made of rubber or a similar material and features a filter cartridge or canister to remove contaminants from the inhaled air.
Origin:
Gas masks have been in use for over a century, with the first prototypes appearing in the late 19th century. They were initially developed for military use to protect soldiers from chemical warfare agents, such as chlorine gas during World War I.
Over time, gas masks have also been adapted for civilian use in various industrial, hazardous materials, and emergency response scenarios. They are commonly found in workplaces where exposure to hazardous substances is a risk, such as in construction, manufacturing, and laboratory settings.
In recent years, gas masks have also become part of personal protective equipment (PPE) for individuals living in areas prone to environmental disasters, such as chemical spills or volcanic eruptions.
