Final answer:
A person injured when crushed or compressed between two or more objects is affected by a mechanical hazard. This is distinct from electrical hazard, which includes thermal hazard due to overheating electric current, and shock hazard when current passes through a person.
Step-by-step explanation:
The hazard category that includes incidents where a person is injured when squeezed, crushed, pinched, or compressed between two or more objects is referred to as a mechanical hazard. This differs from other types of hazards such as electrical hazards, chemical hazards, and biological hazards.
An electrical hazard can result in two main types: a thermal hazard, when excessive electric power causes heating effects that could lead to fires, and a shock hazard, which occurs when electric current passes through a person and can range from painful to lethal. Devices and systems are put in place to prevent these hazards, but they are not related to injuries caused by being crushed or compressed, which fall under mechanical hazards.
