Respirators are a SECONDARY means of protection, according to OSHA
The Pentek system offers primary protection that achieves lead levels below the OSHA Permissible Exposure Limit (PEL) and Action Level. The respirator becomes a secondary protection device.
OSHA directive CPL 02-02-058 states, “The employer is required to use all feasible engineering and work practice controls, including administrative controls, before relying on respiratory protection to achieve compliance with the PEL under 29 CFR 1926.62(c)(3).”
Over an 8 hour work allotment, OSHA establishes a total lead Action Level at 30 μg/m³ and a Permissible Exposure Limit (PEL) at 50 μg/m³. Typical total lead levels during operation of Pentek equipment are 0.1-1 μg/m³, with no detectable respirable lead. Always perform a proper exposure assessment when beginning a new or unique lead abatement project.
OSHA has published an article exploring how Pentek equipment can substantially reduce worker exposure to airborne dust and lead, and recommends use of shrouded tools in their OSHA Technical Manual (paragraph 3-P).
