Physical Hazards

1. Common Hazards Encountered by Computer Technicians and Users

2. Physical Hazards Mechanical Hazards Chemical Hazards Electric Shock Hazards

3. PHYSICAL HAZARDS - defined as “A factor within the environment that can harm the body without necessarily touching it .”

4. - are conditions or situations that can cause the body physical harm or intense stress. - can be both natural and human made elements

5. Examples of Physical Hazards Heat and Cold - The common physical hazard in most industries is heat. The direct effect of heat exposure are burns, heat exhaustion, heat stroke and heat cramps. The indirect effects are decreased efficiency, increased fatigue and enhanced accident rates. Important hazards associated with cold are chilblains, erythrocyanosis , immersion foot and  frost bite  as a result of coetaneous vaso constriction.

6. Light - The acute effects of poor illumination are eye strain, headache, eye pain, lachrymation , congestion around cornea and the chronic effects on health includes "miner's nystagmus ". Exposure to excessive brightness is associated with discomfort, annoyance and visual fatigue. Noise - Auditory effects consist of temporary or permanent hearing loss where as non-auditory effects include nervousness, fatigue, interference with speech etc.

7. Vibration - Vibration affects hands and arms. After some months or years of exposure, the fine blood vessels of the fingers may be increasingly sensitive to spasm. Ultra Violet Radiation - Occupational exposure to UV radiation occurs mainly in arc welding. Such radiations affect the eye, causing intense conjunctivitis and keratitis .

8. Ionizing Radiation - Ionizing radiations are finding increased application in medicine and industry. X-rays and radioactive isotopes are widely used. The radiation hazards compromises of genetic changes, malformation, cancer, leukemia, ulceration and in extreme cases the death.

9. Abrasive Blasting Cash-in-transit activities Construction Work Demolition Work Electrical risks Excavation Work Facilities Falling Objects Flood Recovery Hazardous manual tasks High risk work Overhead and Underground electric lines Plant and structures Quad bikes Sedentary Work Slips, trips and falls Smoking Travel risk Welding
