4. PHYSICAL HAZARDSHeat – Direct and indirect effect at high temperature, radiant heat, heat stagnation.Cold – General & Local cold Injury.Light – Acute & Chronic Effect of bright & dim light & GlareRadiation a. Ionizing – X-Rays, Gamma Rays, Beta Particles, Alpha Particles b. Non-Ionizing – Microwaves, infrared and ultra-violet light.Noise – Auditory and non-auditory effects.Vibration – Hazardous in non permit-able frequency range.

7. Ways of Acquiring Chemical HazardsA. Local Action : Irritants, Sensitizers.B. Inhalation : Dusts – Organic, Inorganic Gases – Simple Asphyxiantes: Methane, Nitrogen, CO2. - Chemical Asphyxiants: CO, Hydrogen Sulphide, HCN - Irritant Gases: Ammonia, SO2 - Anesthetic Gases: Chloroform, EtherC. Ingestion : Metallic Compounds: Arsenic, Antimony, Beryllium, Chromium, Cadmium, Cobalt, Lead, Mercury
8. Disease due to Chemical AgentsGases – Gas poisoningInorganic Dusts: Coal Dusts - Anthracosis Silica - Silicosis Asbestos - Asbestosis Iron - SiderosisInorganic Dusts: Cane Fiber - Bagassosis cotton Dust - Byssinosis Hay Dust - Farmer’s Lung Iron - SiderosisChemicals – Burns, Dermatitis, Cancer, Respiratory, Illness.Metals – Lead, Mercury, arsenic, Chromium Cause Poisoning
9. BIOLOGICAL HAZARDSBacteria –Viruses Fungi – MoldsInsects – Mosquitoes Hazardous Plants – Poison Lvy.BirdsAnimalsBlood-Borne Pathogens
10. Disease due to Biological AgentsHepatitis B VirusHepatitis C VirusTuberculosis – Particularly among Healthcare WorkersAsthma – Among persons exposed to organic dustBlood-Borne Diseases – HIV/AIDSAnthraxBrucellosisTetanusLeptospirosis
11. PSYCHOLOGICAL HAZARDSWork Related Stress – Excess working time and overworkHepatitis C VirusViolence – From outside the organizationBullying – Emotional and verbal abuseSexual HarassmentMobbingBurnoutExposure to Unhealthy Elements – Tobacco, Uncontrolled Alcohol
