As a laser cleaning operator, what are the key protection methods to prevent acetaldehyde exposure from vapor generation during surface treatment?

Question

Accepted Answer

Always prioritize engineering controls like local exhaust ventilation systems to capture and remove acetaldehyde vapors at the source, maintaining airborne concentrations below the OSHA permissible exposure limit of 200 ppm (as an 8-hour time-weighted average) and the NIOSH recommended limit of 25 ppm. Wear appropriate personal protective equipment, including chemical-resistant gloves, safety goggles, and a full-face respirator with organic vapor cartridges if ventilation is inadequate. Monitor air quality periodically using portable gas detectors specific to acetaldehyde to ensure exposure stays within safe limits and conduct regular training on spill response and emergency eyewash stations.
