What respiratory protection should I use when laser cleaning surfaces that may generate lead oxide (PbO) particulates?

Question

Accepted Answer

Use a NIOSH-approved half-face or full-face respirator with P100 filters (or equivalent) rated for particulates to prevent inhalation of lead oxide dust, ensuring a proper fit test and seal check before each use. In high-exposure scenarios during laser cleaning, opt for powered air-purifying respirators (PAPRs) for better comfort and protection, and always perform air monitoring to confirm levels stay below OSHA's permissible exposure limit of 50 µg/m³ for lead over an 8-hour shift. Combine this with engineering controls like local exhaust ventilation at the laser cleaning site to minimize airborne particulates from the start.
