Pronunciation: [ɡˈazmask] (IPA) 
The word "gasmask" can be spelled as two separate words, but when used as a noun to describe a protective device worn over the face to filter air breathed in, it is typically spelled as one word. The spelling of the word is straightforward, with the "gas" portion representing the first syllable, spoken as /ɡæs/, and the "mask" portion representing the second syllable, spoken as /mæsk/. Together, the word is spoken as /ˈɡæsˌmæsk/.
A gas mask is a protective device designed to cover the face and provide a barrier between the wearer and harmful airborne chemicals, gases, or particles. It consists of a mask made of rubber or other suitable materials that completely covers the face from the forehead down to the chin. The mask is equipped with a filtering system that typically includes activated charcoal or other types of filters to purify the air inhaled by the user.
Gas masks are primarily used in situations where there is a potential threat of inhaling toxic, irritating, or contagious substances. They are often employed by emergency responders, military personnel, and individuals working in hazardous environments. The mask is secured to the face with adjustable straps or seals to ensure a tight fit and prevent contaminant leakage.
Modern gas masks may also feature additional components like a transparent visor or eyepieces for improved vision, a microphone and speaker system for communication, or a special port for drinking water. Some advanced models are even equipped with built-in sensors to detect and monitor the concentration of hazardous substances in the surrounding environment.
In summary, a gas mask is a protective device worn over the face to shield the wearer from harmful airborne substances. It utilizes a filtration system to remove or neutralize toxic or dangerous gases, chemicals, and particles, and is commonly used in industrial, military, and emergency settings.
The term "gasmask" is a compound word derived from two individual words: "gas" and "mask".
The word "gas" stems from the Greek word "khaos" meaning "empty space" or "void". It was adopted into Latin as "chaos" and ultimately made its way into English with the meaning of "substance in a gaseous state".
The word "mask" can be traced back to Middle French, where it referred to a covering for the face. This usage can be connected to the verb "masquer" (to disguise) or "masque" (masquerade).
Combining these two words, "gasmask" originally referred to a protective mask designed to prevent the wearer from inhaling harmful gases, particularly in the context of warfare or industrial environments.
