2.7.1 Safety Measures
Protection Tools
Use ventilation devices or respiratory protection tools according to regulations to prevent
gas poisoning, hypoxia, and dust poisoning.
When performing or supervising welding, use protection tools or wear goggles with
sufficient shading degree.
Wear goggles to prevent spatters or welding slag from injuring your eyes.
Use protection gears such as welding-dedicated protection leather gloves, clothes with
long sleeves, foot protection, and aprons.
Set up protective barriers around welding sites to prevent arc from injuring others.
Use soundproof devices to prevent noise hazards.
Use windbreak at the welding site to prevent wind from affecting the welding quality if a
ventilator is used or the outdoor welding environment is windy.
