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 five figures from the Taylor & Barrett Decontamination Unit all wearing black decontamination protective suits with cream gas masks and gloves. One is holding the brush in their right hand with a bucket at his feet, one is holding a gas detector probe, one has a cupped hand to hold a hose, one has a spade and the last a broom.
Although these are marked Taylor & Barrett they are heavier so not sure if later or recast. Figures all in very good condition with only very minor paint loss.
