Gas Masks

Britain decided to issue gas masks to everyone living in britain, because they feared that poison gas was going to be used on their people. Luckily though, there were never any poisonous gasses used in WWII. Babies were given different gas masks then Adults. In efforts to help detect if their was a gas attack, the tops of mailboxes were painted a special coat of paint to help detect if there were any gasses. The government also created gas identification squads. The squads would consist of chemists, and they were to identify what gas was used if there was an attack. People were instructed  by the government to carry their gas masks everywhere. If there was an air raid attack, people outside were told to put their gas masks on immediately. They were afraid that the Germans were going to drop blister gas or mustard gas. Blister gas cause severe burning of the skin. Mustard gas is similar. There were also decontamination squads formed to help treat victims in a poisonous gas attack. 

We will never really know how effective their system was, because there never was a gas attack.
