Exposure to ________ materials may cause freeze burns and frostbite.

Exposure to ________ materials may cause freeze burns and frostbite.

• A. Cryogenic
• B. Corrosive
• C. Radioactive
• D. Flammable

Answer: (A)

Exposure to cryogenic materials can cause freeze burns and frostbite because these substances are stored and used at extremely low temperatures. When skin comes into contact with these ultra-cold liquids or vapors, the rapid loss of heat freezes tissue, leading to ice crystal formation inside cells, tissue damage, and potential deep frostbite. Even brief contact can be serious, and protection is essential—insulated cryogenic gloves, face shields, and proper handling procedures help prevent these cold injuries. Corrosive materials cause chemical burns, not freezing injuries. Radioactive materials can cause radiation burns or other health effects, not typically frostbite. Flammable substances can burn due to ignition, but frostbite isn’t the result of exposure to fire or heat.
