Welding Safety Hazards and Precautions - Health and …
Some welding processes are noisy in their own right – MIG may emit noise at around 90dB; friction welding of steel and vibration welding of hard plastics can also emit high levels. To comply with the Regulations, an employer has to conduct a risk assessment of the noise in the working environment and do all that is possible to reduce the level so far as is reasonably practicable.
