LaserPecker's LSO material covers the formal training. These are the community's notes on what the role means day to day, especially in a shared space, a school or a business.
What an LSO actually does
- Owns the written operating procedure and keeps it current
- Decides which materials are allowed, and controls access to them — a locked material cupboard removes the PVC problem entirely
- Verifies eyewear is correct for every wavelength in use, and that it isn't scratched or expired
- Checks extraction works before sessions, on a tick sheet rather than by feel
- Trains and signs off operators, and keeps the record
- Investigates incidents and near-misses, including the ones where nothing burned
Eyewear is where people get caught out
Buy glasses rated for the specific wavelength, with the OD number printed on the frame. Diode glasses (445–455nm) are transparent at 1064nm. A dual-source machine needs protection valid for both, or discipline about which source is running.
Non-negotiables worth writing down
- Machine never runs unattended, including "it's only two minutes".
- Interlocks never bypassed, for any reason.
- Unknown material never goes in.
- Fire kit in the room, and everyone knows where it is.
- Every job logged: name, material, settings, duration.
LaserPecker publish their own documentation on this topic — worth reading alongside these community notes.
