What protective measures should I take to avoid inhaling tin oxide (SnO₂) particulates during laser cleaning of metal surfaces?

Question

Accepted Answer

Prioritize using a NIOSH-approved half-face or full-face respirator with P100 filters, ensuring a proper fit test before starting work, as laser cleaning can aerosolize fine SnO₂ dust rapidly. Implement local exhaust ventilation or work in a fume hood to capture particulates at the source, and perform operations in a well-ventilated area to keep exposure below the OSHA PEL of 0.5 mg/m³ (as Sn). After each session, clean up any settled dust with HEPA-vacuuming rather than sweeping to prevent re-suspension.
