4. Physical Hazards Work Health and Safety Physical hazards include: Heat
  Cold
  Noise
Radiation
Electricity
Vibration
High Pressure

5. Heat Work Health and Safety Being exposed to excessive heat can cause:
  Heat rash
  Heat cramps
  Heat exhaustion
Heat stroke

6. Heat Work Health and Safety Heat hazards can be controlled through:
  Ventilation and air conditioning
  Scheduling
  Job rotation
Breaks
Drink fluids
Getting used to heat gradually
Personal protective equipment

7. Cold Work Health and Safety Being exposed to cold can cause: Frostbite
  Hypothermia
  Trench foot
Eye injuries

8. Cold Work Health and Safety
The following steps can protect workers from the cold:
  Give workers frequent rest periods in a warm area
  Provide clothing designed to keep cold out
  Workers should wear layers of vented clothing
Build barriers around the work site to block wind
Supply workers with warm beverages
Keep vehicles in good running order

9. Noise Work Health and Safety
Being exposed to excessive noise can cause:
  Temporary hearing loss
  Permanent hearing loss
  Stress
Fatigue
Nervousness
Increased blood pressure

10. Noise Work Health and Safety
You can protect workers from noise hazards by:
  Using machinery/equipment that makes less noise
  Enclose machines/equipment to reduce noise
  Rotating jobs reducing time exposed to noise
Move workers away from noise
Keep equipment in good working order

11. Radiation Work Health and Safety
Main health effects from exposure to radiation include:
  Cancer
  Infertility
  Birth defects
Radiation sickness

12. Radiation Work Health and Safety
Workers should be aware of radiation hazards through:
  Labelling and warning signs
  Monitors that measure radiation being emitted
  Radiation badges worn to measure employee’s exposure
Also preventative controls should include:
Properly shield and maintain equipment
Move workers away from sources of radiation
Wear glasses with UVR filter lenses
Cover skin

13. Electricity Work Health and Safety
Electricity can kill. Safety measures include:
Having qualified workers install electrical systems
Using proper electrical outlets
Not allowing electrical cords to contact water
Repair or replace worn power cords or extension leads
Using ground fault circuit interrupters (GFCI)
Properly grounding electrical machinery/equipment
Keeping a safe distance from overhead power lines
Locating underground utility wires before digging
Finding shelter when there is lightning

14. Vibration Work Health and Safety
Many hand tools can cause ‘Hand/Arm Vibration Syndrome’ (HAVS)
Symptoms include:
  Numbness
  Pain
  Blanching of the fingers
Loss of finger dexterity
Discomfort and pain in upper limbs

15. High Pressure Work Health and Safety
Many workplaces contain high pressure hazards.
High pressure hazards include:
  Injuries caused by sudden changes in pressure
  Injuries caused by ruptured containers
  Explosions
High pressure injuries include:
Rupture of the tissue
Injection injuries
Severe eye injuries
Materials can be toxic

16. High Pressure Work Health and Safety High pressure controls include:
  Training in using high pressure tools
  Training in maintenance of high pressure vessels
  Avoid pressure build up in containers
Do not expose high pressure containers to a heat source
Maintain equipment in the highest possible condition
Do not blow compressed air directly at the body
Install pressure relief valves where possible
Secure all high pressure gas cylinders
Certification of workers
