As a laser cleaning operator, how can I protect myself from SO₂ exposure if the process generates this gas from sulfur-containing materials?

Question

Accepted Answer

Always prioritize engineering controls like local exhaust ventilation to capture and remove SO₂ at the source, maintaining exposure below the OSHA permissible limit of 5 ppm (parts per million) over an 8-hour shift. Wear a full-face respirator with an appropriate cartridge rated for acid gases (e.g., NIOSH-approved P100 with acid gas cartridge) and ensure personal protective equipment like gloves and protective clothing to avoid skin contact. Regularly monitor air quality with SO₂ detectors or badges, and evacuate if levels exceed 5 ppm, seeking fresh air immediately if irritation occurs.
