My special interest object is a 'general civil respirator' issued to the British people in the Second World War. These mass-produced objects have come to symbolize life in the UK, even though it has never been used in action: the much-feared poison gas bomb attacks never materialized. There are gas masks for adults, children, babies, horses … and even dogs. There are also complete gas mask hood systems for families.

Gas masks first became standard military equipment after the Germans pioneered chemical warfare on the Western Front of the First World War at the Second Battle of Ypres in 1915. The first gas masks for use in warfare were developed during the First World War when the German military pioneered the use of chlorine as a weapon – the original WMD.

The first gas masks were simple filters of damp cotton and were soon superseded by cloth bags soaked in chemicals. By the end of that conflict, the pattern for modern gas masks had been established, with a face mask, eye-pieces, a chemical filter, and a container.

In 1934, the British government asked its scientists at the Porton Down laboratory to design a civilian respirator that could be mass-produced at a unit cost of two shillings. The result was the General Civilian Respirator, familiar to the Second World War generation and to later generations from films, photographs, and stories of the period.

The following describes gas masks, including all fully assembled air purifying masks, that can be used to protect the lungs from harmful atmospheres.

(1) Gas mask that can be mounted front or backward.

A gas mask that includes a complete facepiece, breathing tube, canister at the back or front, canister harness, and all associated connections. You can buy gas masks via https://www.gasmaskpro.com/.

 

(2) Chin-style gasmask.

A gas mask that includes a complete facepiece, a canister, and any associated connections.

(3) Escape gas mask.

A gas mask that is used to escape from dangerous atmospheres. It consists of a mouthpiece or facepiece, a canister, and any other connections.

Gas masks are further described according to the type of gases or vapors against which they are intended to provide respiratory protection.

Approval can be given for acid gases and organic vapors in general or for specific acids gases or organic vapors.

Not to be used against gases or vapors that have poor warning properties (except where MSHA and Occupational Safety and Health Administration standards allow such use) or those that generate high heats or react with sorbent material in the canister.

The use of the gas mask could be restricted by factors like lower explosive limit, toxicological consequences, and fit of the facepiece. The applicant must specify in the instructions for selecting, using, and maintaining the gas mask any limitations on the gas mask's service life or sorbent capacities.
