When welding or cutting metals coated with mercury-bearing materials indoors or in confined spaces, you must use local exhaust ventilation or airline respirators unless atmospheric tests show that employee exposure is within acceptable concentrations [1]. Outdoors, respirators certified by NIOSH under 42 CFR Part 84 are required [1].
To ensure proper protection, a comprehensive PPE program should be in place, addressing elements such as PPE selection based on site hazards, proper fitting, maintenance, storage, decontamination, and disposal [2].
Note: This information is specific to welding and cutting operations. For other tasks involving mercury, consult a safety professional to determine the appropriate PPE.
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
