What is a hazard list tree classes of hazards and give an example of each one?

A hazard list tree categorizes potential hazards into distinct classes to facilitate risk management and safety planning. The main classes of hazards include physical hazards (e.g., machinery accidents), chemical hazards (e.g., exposure to toxic substances), biological hazards (e.g., bacteria or viruses in the workplace), and ergonomic hazards (e.g., repetitive strain injuries from poor workstation design). Each class highlights specific risks that require tailored safety measures to mitigate their impacts.
