Which item is NOT LOX PPE?

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

Answer: (C)

When working with liquid oxygen, the gear you use must protect you from both the extreme cold and the risk of ignition in an oxygen-rich environment. Items chosen as LOX PPE are designed to act as a barrier between skin and LOX, prevent contamination, and stay compatible with cryogenic conditions. LOX Boots are built to withstand cryogenic exposure and provide good traction, reducing the chance of slips on wet or icy surfaces around LOX spills. Cuffless coveralls keep the body fully covered and minimize entry points where LOX might contact skin, while also avoiding the hazards that cuffs can pose in a splash-heavy area. The rubber-coated, cotton-duck, impermeable apron adds a sturdy barrier over the torso and arms, protecting clothing and skin from splashes and spills while using materials that resist ignition and are easier to decontaminate. A lanyard, by contrast, is simply a securing strap or tether. It does not provide a protective barrier, does not shield skin from cryogenic exposure, and does not address LOX-specific hazards. Therefore it is not considered LOX PPE.
