Explanation:

1. PEL stands for Permissible Exposure Limit, which is a worker's maximum exposure limit.
2. When body - temperature drops a few degrees below normal, it is cold stress. Heat stress and heat exhaustion are related to high temperatures, and there is no such thing as cold stroke.
3. Asbestos exposure can cause eye irritation like swollen eyes and a sandy feeling. Flash burn is related to intense heat, heat stroke is a heat - related medical condition, and frostbite affects skin and tissues in cold conditions.
4. The three elements for a fire are fuel, oxygen, and an ignition source (not combustible liquid as a separate element from fuel).
5. A confined space is an enclosed space with limited access for entry and exit.
