Which item is part of LOX PPE?

• A. Cuffless coveralls
• B. Rubber Coated, cotton-duck, impermeable apron
• C. LOX Boots
• D. Clean Dry Gloves

Answer: (C)

Working with liquid oxygen requires gear that protects you from extreme cold and keeps all contact with the liquid or its vapors dry and safe. Boots designed for LOX are made to insulate the feet and provide a moisture barrier, so the skin doesn’t freeze or sustain frostbite if liquid oxygen splashes or condenses on footwear. They also help prevent oils or greases from coming into contact with the LOX, which is critical because LOX is a strong oxidizer and any contamination can create hazards.

The other items don’t address the LOX-specific hazards as directly. Cuffless coveralls offer body coverage but don’t provide the dedicated cryogenic protection for feet. An impermeable apron protects the torso from splashes but leaves the feet unprotected and isn’t the standard LOX PPE item. Clean dry gloves are important, but the question points to the footwear as the defined LOX PPE piece in this context.
