Which hazard is specifically associated with Liquid Oxygen (LOX)?

• A. Frostbite
• B. Fire hazard
• C. Explosive risk
• D. Toxicity

Answer: (A)

Liquid Oxygen is a cryogenic liquid, so its extreme cold is the hazard most specifically tied to it. At about -183°C, contact with LOX can cause rapid freezing of skin and tissue, leading to frostbite or cryogenic burns in a fraction of a second. That cold burn risk is unique to handling cryogenic liquids like LOX, so protective gear such as insulated gloves, face protection, and proper transfer procedures are essential to prevent serious injury. Fire and explosive risks involve the oxidizing nature of LOX—oxygen-rich environments can make fires burn hotter and can fuel rapid, violent reactions with fuels. But those hazards stem from the oxygen-enriched atmosphere itself, not from a property unique to LOX as a cryogenic liquid. Toxicity isn’t a primary concern with LOX, since it’s non-toxic; the bigger risk is displacing air in confined spaces and creating asphyxia hazards, which is about the environment rather than an LOX-specific hazard.
