The Air Raid Precaution Act of 1937 presented a statutory duty on local authorities to provide shelter and anti-gas precautions for their community. The policy allowed for protection by personal gas masks and domestic air raid shelters, most commonly Anderson shelters. In addition, local government were also responsible for siren warnings, first aid and rescue services, firefighting, gas decontamination and enforcement of blackout regulations by ARP wardens and civil police.
Here are two figures from the Taylor & Barrett Decontamination Unit set both wearing black decontamination protective suits with white gas masks and gloves. One is holding the brush in their right hand with a bucket at their feet and the other has a cupped hand to hold a hose.
both figures are in very good original condition with only very minor paint loss.
