UV Laser (355 nm / Class 4) — Workplace Safety & Compliance Document Pack (Digital Download) projectile We update and improve ourProfessional Safety Documentation for Class 4 UV Laser Installations UV lasers at 355 nm are Class 4 the most hazardous laser classification but they're dangerous in ways that are fundamentally different from fiber or CO lasers. At 355 nm, the damage mechanism is photochemical, not thermal: UV photons carry enough energy (3. 5 eV) to break molecular bonds on contact, causing photokeratitis ("welder's flash") from a single exposure and cumulative
