Lesson 5: Physical Hazards

Physical Hazards


When learning about Physical Hazards, it's important to know that:

  • Physical Hazards are a risk to your physical safety.

  • Physical Hazards can include things that you can see, such as cords on the floor, machines, tools, knives.

  • Physical Hazards can also include forms of physical energy, such as noise, vibration, extreme temperatures, radiation.

  • Injuries from Physical Hazards can be immediate, such as a cut or broken bone or it can be delayed such as a gradual loss of hearing from noise exposure.

  • Most injuries reported to the Workers Compensation Board, are the result of physical hazards.


  • Temperature extremes â€” Working in cold or hot conditions can lead to freezing/loss of heat or burning/too much heat. 

  • Noise â€” Noisy equipment or a noisy workplace can lead to hearing loss.

  • Radiation â€” The rays from the sun or other radioactive materials can cause cancer and other illnesses. 

  • Vibration â€” Shaking movements from equipment, such as jack hammers, can lead to many kinds of injuries. 

  • Pressure â€” Changes in air pressure, such as working with power tools, or working as a diver, or mountain climbers can result in injury. 

  • Mechanical â€” Any type of equipment, machine or tool can be a mechanical hazard. Workers can be caught in, pinned between, or run over. 

  • Electrical â€” Any type of electrical equipment can become a hazard and cause injury or death. 

  • Gravitation â€” Objects or people falling and being pulled to the ground by gravity (the earth's pull).
