9th , 1938
Gas had been used a great deal in the First World War and many soldiers had died or been injured in gas attacks. Mustard gas was the most deadly of all the poisonous chemicals used during World War I. It was almost odourless (could not be smelt easily) and took 12 hours to take effect. It was so powerful that only small amounts needed to be added to weapons like high explosive shells to have devastating effects.
There was a fear that it would be used against ordinary people at home in Britain (civilians).
In 1938, the British Government gave everyone, including babies, gas masks to protect them in case the Germans dropped poison gas bombs on Britain. The government had planned for tens of thousands of deaths in London alone.
With 1939 and the outbreak of war, these masks were issued to the public in cardboard boxes with strict instructions that they be carried at all times, without exception. Fines would be imposed if you were caught without your respirator.
