![]() One of the most notable gas masks used during WW1 was the British Small Box Respirator or SBR designed in 1916 and the German GM-15 mask. The allies soon added filter drums to their respirators as well. soon as troops learned that gas was in their area, they had to put on masks. Finally, towards the end of the war the in 1916, the Germans added larger air filter drums to their respirators containing gas neutralizing chemicals. From a medical standpoint, World War I was a miserable and bloody affair. The hood fitted the head to the shoulders and had a mica window. It had a wool flannel hood entirely soaked in a solution called the Hypo solution, which was a mixture of sodium hyposulfite, sodium bicarbonate and glycerine. The result was the 'British Hypo Helmet' or, officially, the 'British Smoke Hood'. Next, since there were limitations of the Black Veiling Respirator it focused British attentions on a more effective and operationally practical replacement. Suffering in later years from chemically-induced illnesses and disabilities, they would sometimes fight unsuccessfully to have medical claims approved, having failed to document their injuries at the time.After the first gas attacks by the Germans the British made crude masked made of cotton and a long cloth that was dipped in a solution of bicarbonate of soda (known as the black veil). Many soldiers never reported their multiple minor gassings, which, at the time, were not immediately debilitating. There were approximately one million gas casualties to all armies during the war, 12,000 of them Canadian. In the last year of the war, soldiers of all armies struggled across battlefields often choked with gas. It attacked the skin and blinded its victims, thereby defeating existing gas masks and respirators.īy the Armistice, chemical shells made up 35 percent of French and German ammunition supplies, 25 percent British and 20 percent American. ![]() The Germans unleashed mustard gas in the summer of 1917. Phosgene, introduced in late 1915, was nearly invisible and much more lethal than chlorine. By 1917, chemical shells, projectors, and mortars could deposit dense gas barrages on enemy lines, or behind them on supply routes, reserve trenches, or gun batteries. Fighting on the Chemical Battlefieldĭeadlier gasses and more reliable delivery systems were introduced later in the war. ![]() The British responded with their own chlorine attacks in September 1915, during which a change in wind direction resulted in more than 2,000 British soldiers being gassed by their own chemicals. ![]() But the introduction of increasingly effective gas masks and other precautions helped counter the German advantage. With the introduction of poison gas, many contemporaries feared that the Germans had discovered a war-winning weapon. After several days of chaotic and brutal fighting, the Ypres position remained in Allied hands. The gas shocked but, while some troops fled in panic, the Canadians held their ground. With the wind blowing over the French and Canadian lines on 22 April, they released the gas, which cooled to a liquid and drifted over the battlefield in a lethal, green-yellow cloud. Results of Gas at YpresĪt Ypres, Belgium, the Germans had transported liquid chlorine gas to the front in large metal canisters. The first large-scale use of lethal poison gas on the battlefield was by the Germans on 22 April 1915 during the Battle of Second Ypres. ![]()
