Laser Operator Safety: The Pre-Session Checklist That Prevents Accidents

Laser accidents are process failures, not equipment failures. A laminated pre-session checklist — run before every client, every room, every day — eliminates nearly all of the classic injury scenarios.

Room and Equipment (before first client)

• Warning signage on the door, windows covered, reflective surfaces removed or draped
• Handpiece inspection: fiber integrity, lens clean, aiming beam aligned
• Emergency stop reachable; footswitch guarded against accidental press

People (before every session)

1. Occlusive or wavelength-matched goggles on client AND operator — corneal burns are the most common laser injury and entirely preventable
2. Client skin inspected: moles, tattoos, jewelry mapped and excluded
3. Photosensitivity medication screen — the answer changes the session or cancels it
4. No flammable prep: alcohol-based solutions fully dry before any energy pass

During and After

Holster the handpiece between passes — never set it on the bed. Plume extraction on ablative work. Post-session: handpiece returned to cradle, key/lock secured, room re-verified before the next client enters. Devices across this site — diodes, CO2 platforms, picosecond systems — ship with operator safety documentation; the checklist above is the discipline layer that makes it real.
