r ' and silicates fumes from the electrode, CO,C02, NOx and 0 3 inhaling them can lead to irritation of the respiratory tract and to pneumoconiosis-type effects ,above all ultraviolet radiation may caused severe health. The soldering has same impact due to generation of rosin fumes. It is estimated that the person associated with welding activities may Fig-8 (A) - Rotating exhaust attached with Exhaust system 2.9 Prevention & Control of Chemical Fumes Hazards: The gravimetric and physical analysis of raw material, intermediate and finished product is part of statuary requirement. The chemist involved in day to day analysis is expose to acidic and basic fumes and very fine particulate matter. The person may exposed to different kind of radiation such as X-rays and Y-rays too. While equating the breath - 18-221itre/day of fumes during work period . Hence a specific prevention and control measured are required to be adopted to prevent from welding fumes hazards. Specific measures such as spot welding installation of a local extraction system and PEEs may be adopted shown as: Fig-8 (B) exposure in laboratory, time period of exposure, level and concentrations of hazards were alarming and force to think about the laboratory workplace exposure limit. We all believe by taking care of chemicals as per MSDS, proper ventilation, baking of chemical in heat chamber, and controlled noise can maintain the workplace exposure limit in laboratory. The avg. Exposure time is 6.5 hrs and concentration observed were 5-12mg/m3 10 0 Fig-9 (A) 2.10 Code of Practice: Fig-9 (B) Fig-9 (C) • Design and organisation of systems of work at the workplace • Provision of suitable equipment for work • Reducing to minimum number of workers exposed or likely to be exposed • Reducing to minimum duration and intensity of exposure • Reducing the quantity of hazardous • Suitable working procedures • Appropriate hygiene measures • Information and training of the workforce 2.11 Design requirements for Control of dust I fumes Hazards : • Specific systems for replacing extracted air. • Appropriate dimension of the heating or cooling system
