Liquid gases stored at -297°F create which hazard?

Explanation:
The main idea here is cryogenic hazards. Liquids stored at such ultra-cold temperatures can cause immediate cold burns or frostbite on contact, since the skin and tissues are instantly chilled. They also make nearby materials become brittle, which can lead to cracks or leaks in equipment if not designed for cryogenic use. Additionally, the cold vapors can displace oxygen in the air, creating an asphyxiation risk in poorly ventilated spaces. When these liquids warm, they rapidly vaporize and expand, generating pressure that can rupture containers if venting isn’t proper. This is different from thermal hazards (heat), electrical hazards, or biological hazards, which involve other risks.
