What personal protective equipment is essential when transferring cryogenic liquids?

• A. Rigid chemical splash goggles only
• B. Cryogenic gloves and face shield
• C. Standard cotton gloves
• D. No PPE required

Answer: (B)

Transferring cryogenic liquids poses two main hazards: extreme cold that can cause rapid frostbite on skin and splashes or vapors that can injure the eyes and face. To safely manage both, you need protection that is specifically designed for cryogenic temperatures and splash exposure. Cryogenic gloves are built to withstand the extreme cold and prevent liquid from soaking through to the skin, protecting the hands and wrists. A face shield (or equivalent eye/face protection) guards the eyes and face from splashes and cold vapors. Relying on only rigid chemical splash goggles leaves the hands unprotected against the severe cold, and standard cotton gloves offer no protection against cryogenic temperatures. No PPE at all is unsafe for handling such hazardous materials. The combination of cryogenic gloves and a face shield provides the necessary, practical protection for this task.
