welding risk assessment pdf

INTRODUCTION Hazard identification and risk assessment is systematic process to protect the health and minimize danger to life of workers, property and environment. For example, a car mechanic wearing RPE with good general ventilation in the workplace, carrying out an occasional short welding job on a car with a broken exhaust support bracket, would meet the minimum requirement for compliance. Employers should have a programme of regular checks for fixed and mobile welding sets. v. Electric shock. Mechanical general ventilation uses fans mounted in the ceiling or high up on a wall to extract the air in the room and draw in clean air to disperse airborne contaminants. Companies who manage their slip and trip risks effectively can reduce these types of accidents. HSE guidance Hot work on drums and tanks gives a simple description of the safe way to do this work.
