As a laser cleaning operator, what protection methods should I use to minimize exposure to silicon dioxide (SiO₂) particulates generated during the process?

Question

Accepted Answer

Start by assessing the workspace to minimize airborne exposure through engineering controls like local exhaust ventilation or enclosed cleaning systems to capture particulates at the source. Wear a properly fitted NIOSH-approved respirator with an N95 or higher rating for particulate protection, along with gloves, safety goggles, and a coverall to prevent skin and eye contact. Regularly monitor air quality with particulate samplers and follow decontamination procedures after shifts to avoid secondary exposure.
