Did air raid shelters contain asbestos?

Yes, many air raid shelters built during and after World War II contained asbestos. Asbestos was commonly used for its fire-resistant properties and insulation capabilities. This posed health risks, as exposure to asbestos fibers can lead to serious respiratory diseases, including asbestosis and mesothelioma. Proper safety measures and regulations regarding asbestos have since been implemented to mitigate these risks.
