Both equipment were to be present on the troop members during battle. The masks became effective in being able to sustain phosgene gas, through its added hexamine to sodium phenate solution which acted as an absorbent to the phosgene gas. The PH helmet was used throughout early 1916 by the British troops in which was designed to be tucked under the shirt of the wearer. While the respirators acted as the first line of defense in some British troops, other Canadian and some British troops were still subjected to the earlier and less effective anti gas masks, the PH helmet. The use of the small box respirators had lowered mortality rates significantly for this reason the creation and usage of the mustard gas, a vesicant that burned the skin, was introduced as the new weapon of chemical warfare in 1917.Ĭanadian troops began to receive small box respirators in late November 1916. 85% of the fatalities that occurred due to chemical weapons, was from the phosgene mixed chlorine gas. Soldiers that were affected by the gas, did not recall feeling symptoms until hours later. Psychological impacts of the gas had resulted in unexplained anxiety attacks which would cause men to tear off their gas masks to breathe correctly exposing them to the gas. Phosgene was up to six times as potent than chlorine and did not suggest any urgent symptoms that was associated with the coughing and discomfort that chlorine did. The situation became problematic on the introduction of the mixed phosgene and chlorine as phosgene is colorless and smells of freshly cut hay. Chlorine was readily detected in battles as the gas tainted a yellowish green cloud and had a pungent odor. British anti gas helmets were appointed to repel the chlorine gas issues later presented when the helmets could not withstands the effects of the phosgene gas. The gas was later used against British Troops on the Western Front in Flanders in December 1915. It was placed into specialized cylinders that released into a dense cloud that settled in enemy trenches to draw soldiers out from protected areas. German scientists at the Kaiser Wilhelm Institute developed the weaponized chlorine gas. The first use of phosgene and chlorine gas was on 19 December 1915 whereby it was used against French and Canadian units in the Second Battle of Ypres. The mask was created to provide reliable protection against chlorine and phosgene gas. The small box respirators were introduced into the British and Imperial forces on the Western Front (World War I) in 1916. Members of the Irish Guards conduct a test with P helmets before going into combat. The canister, which was oval shaped, contained cotton and wire gauze filters to retain any poisonous substances. The rubber hose is around 30 cm in length and is made of vulcanized stockinette fabric making the hose flexible and strong. The mouthpiece is joined by a brass tube to the rubberized hose leading to the canister. The mask contains an internal mouthpiece with an exhale valve made of black rubber consisting of a flange to fit both mouth and teeth. A circular wired nose clip with rubber covered jaws sits between the internal region of the eyes. The circular eye pieces are set in metal rims that are consistent of celloid which is sealed on with rubber sealant. Khaki cotton tape, located in the middle of forehead region of the mask, connects to black elastic strips from the cheeks to ascertain a suitable fit for the carrier. The respirator mask is light in weight and is made from khaki cotton fabric that is plated with a thin layer of black rubber. The small box respirator consists of a face mask made of rubberized fabric connected by a rubber fabric hose to a canister made of tinplate containing a chemical absorbent. Light and reasonably fitting, the respirator was a key piece of equipment to readily protect the respiratory health of soldiers on the battlefield. Death rates were high with exposure to both the mixed phosgene chlorine and mustard gas, however with soldiers having readily available access to the small box respirator, death rates had lowered significantly. A later and more toxic gas, Mustard Gas, was created by Germans and was a vesicant that burnt the skin of individuals that were exposed to it. The respirator offered a first line of defense against the gas. In late 1916, the respirator was introduced by the British with the purpose to provide reliable protection against chlorine and phosgene gas. The small box respirator was the initial compact version of the recent gas mask. A British soldier wearing the Small Box Respirator during World War I
