1. Audit Objectives and Regulatory Context
A periodic Laser Safety Audit verifies that physical controls, administrative protocols, and personal safety equipment function properly to prevent accidental eye and skin exposure, electrical shock, and fire hazards in laser operating zones.
2. Critical Inspection Categories
A. Engineering Controls Inspection
- Verification of fail-safe door interlocks on Class 4 laser areas.
- Inspection of diffuse beam dumps and stray reflection shields.
- Testing of remote emergency stop (E-stop) buttons and laser warning lights.
B. Personal Protective Equipment (PPE) Verification
- Eyewear physical condition: check for scratches, cracks, discoloration, or coating degradation.
- Label verification: ensure all eyewear in the area matches the laser wavelength and meets required OD / EN 207 LB ratings.
C. Administrative and Operational Checks
- Current inventory of all active Class 3B and Class 4 laser systems.
- Signed Standard Operating Procedures (SOPs) on display.
- Training and refresher records for all laser operators.
