What type of respirators must be used by employees performing welding, cutting or heating operations on metals that contain lead,cadmium, mercury in open air?
Answer (1)
Workers engaged in welding, cutting, or heating metals that contain lead, cadmium, or mercury in open air should use powered air-purifying respirators (PAPRs) or air-supplied respirators. These types of respirators are designed to filter harmful fumes and particles, ensuring protection from toxic substances like lead, cadmium, and mercury that can be emitted during such activities. In addition to respiratory protection, adequate ventilation is also essential to minimize airborne contaminants.
