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

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

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

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

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

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

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

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

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

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  

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

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

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
