5 Ergonomics Fitting the job to the worker Designing machines, tools, equipment, processes Layout Methods of works and environment Ergon = work Nomos=

6 Occupational Environment Man and physical, chemical and biological agents Man and machines Man and man

7 Occupational Hazards Hazards Physical Chemical Biological Mechanical Psychological &Social

8 Occupational diseases Due to physical agents heat, cold, light, pressure, noise, radiation, mechanical factors, electricity Due to chemical agents Gases, dusts (organic/ inorganic), metals, chemicals, solvents Due to biological agents Brucellosis, leptospirosis, anthrax, tetanus etc. Occupa- tional cancers Of skin, lung, bladder Occupa- tional dermatitis Dermatitis, eczema Psycho- logical origion Hypertension, peptic ulcer

9 Pneumoconiosis Dust particles 0.5 – 3 micron Chemical composition, fineness, concentration, period of exposure, individual susceptibility. Inorganic and organic dusts

10 INORGANIC DUSTS Silicosis Free silica/silicon dioxide Mining, pottery, sandblasting etc. Irritant cough, dyspnoea on exertion, chest pain Snow storm appearance Dust control measures: substitution, enclosure, isolation, hydroblasting, good housekeeping. Regular examinaton Mines act, factories act

11 INORGANIC DUSTS Anthracosis Coal Simple pneumoconiosis, progressive massive fibrosis. Indian mines act, Workmans compensation act Asbestosis Silicates of Mg, Ca, Na. Serpentine /Amphibole Asbestos,cement,firepro of,textiles, roof lining Respiratory insufficiency,Ca bronchus, mesothelioma Safer types, substitution, rigorous dust control measures, periodic examination, continuing research.

12 ORGANIC DUSTS Bagassosis Sugar cane dust, thermoactinomyces sacchari, Cane sugar industry, paper,rayon,cardboard Breadthlessness, cough, haemoptysis, slight fever, Mottling in lung shadow. Dust control, Personal protection, Medical control, Bagasse control-moisture >20%,2% propionic acid.
