What are the three primary hazard categories

[DigitalExplorer]

I'm looking for help understanding the three primary hazard categories. Does anyone have experience or knowledge in this area? I'm trying to determine which categories are considered primary and what the differences are. Any advice would be greatly appreciated.

Primary Hazard Categories

The three primary hazard categories are Biological, Chemical, and Physical. Biological hazards refer to living organisms, such as bacteria, viruses, fungi, and parasites, that can cause harm to humans. Chemical hazards refer to hazardous substances, such as toxins, solvents, acids, and bases, that can cause harm to humans. Physical hazards refer to environmental conditions, such as temperature extremes, vibration, and noise, that can cause harm to humans.
