1. Mechanical hazards: These are hazards that result from machines or processes that can cause physical injury, such as moving parts, noise, or vibrations.
2. Ergonomic hazards: These hazards are related to the design and layout of workspaces, and can result in musculoskeletal disorders or injuries, such as back pain or repetitive strain injuries.
3. Chemical hazards: These hazards involve exposure to potentially harmful chemicals, such as toxic substances, flammable materials, or gases.
4. Physical hazards: These hazards include sources of energy, such as electricity, radiation, or extreme temperatures, which can cause burns, shock, or other physical damage.
