Respirator Use - Employee

Employees must use respirators during the following activities:

• Class I asbestos jobs
• Class II work where ACM is not removed substantially intact
• Class II and III work not using wet methods
• Class II and III work without a negative exposure assessment
• Class III jobs where thermal system insulation or surfacing ACM or PACM is cut, abraded, or broken
• Class IV work within a regulated area where respirators are required
• Work where employees are exposed above the time weighted average or excursion limit
• Emergencies

Employers must provide respirators at no cost to workers, selecting the appropriate type from among those certified by NIOSH.
