Physical Hazards
Physical hazards include:
Heat Cold Noise Radiation Electricity Vibration High Pressure
4
Work Health and Safety
Heat
Being exposed to excessive heat can cause:
Heat rash Heat cramps Heat exhaustion Heat stroke
5
Work Health and Safety
Heat
Heat hazards can be controlled through:
Ventilation and air conditioning Scheduling Job rotation Breaks Drink fluids Getting used to heat gradually Personal protective equipment
6
Work Health and Safety
Cold
Being exposed to cold can cause:
Frostbite Hypothermia Trench foot Eye injuries
7
Work Health and Safety
Cold
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
8
Work Health and Safety
Noise
Being exposed to excessive noise can cause:
Temporary hearing loss Permanent hearing loss Stress Fatigue Nervousness Increased blood pressure
9
Work Health and Safety
Noise
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
10
Work Health and Safety
Radiation
Main health effects from exposure to radiation include:
Cancer Infertility Birth defects Radiation sickness
11
Work Health and Safety
Radiation
12
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
Work Health and Safety
ElectricityElectricity 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
13
Work Health and Safety
Vibration
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
14
Work Health and Safety
High Pressure
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
15
Work Health and Safety
High Pressure
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
