Standards by safety decision
| Standard | Decision area | Practical output |
|---|---|---|
| GB/T 7247.1-2024 | Laser product classification and China-market safety alignment. | Laser class, label language, and product documentation baseline. |
| IEC 60825-1:2014 | International laser product safety classification. | Class definition, emission limits, and laser-product safety files. |
| ISO 11553-1:2020 | Laser processing machine safety requirements. | Machine enclosure, guards, interlocks, and risk-reduction controls. |
| ANSI Z136.1-2022 | Laser safety programs in US facilities. | NOHD, eyewear OD, controlled area, and safety program items. |
| OSHA 1910 Subpart Q | US welding, cutting, and brazing workplace rules. | Ventilation, fire prevention, workplace access, and operator protection. |
Cell release checks
| Area | What to verify | Release evidence |
|---|---|---|
| Beam containment | Normal operation and service positions contain direct and specular reflection paths. | Marked cell drawing with beam path, reflection risks, viewing windows, and beam dumps. |
| Interlocks and stops | Doors, covers, access panels, and emergency stops disable or control laser emission as designed. | Interlock test record with pass/fail result for each access point. |
| Eyewear | Optical density and wavelength match the laser and exposure assumption. | Eyewear list with wavelength, OD, condition check, storage location, and user group. |
| Fume control | Capture method matches material, coating, duty cycle, and operator position. | Hood location, airflow check, filter stage, maintenance interval, and rejected smoke observations. |
| Access and training | Controlled-area entry, signage, authorized users, and emergency procedure are in place. | Operator checklist, training record, and visible signage at the cell. |
Changes that require a safety recheck
| Change | Why it matters | Minimum recheck |
|---|---|---|
| Wavelength or laser source | Eyewear OD, exposure assumptions, and reflections can change. | Recalculate hazard assumptions and update eyewear/signage before trials. |
| Optics or focus | Beam diameter and irradiance at accessible points can shift. | Review beam path, enclosure viewing ports, and service procedure. |
| Material or coating | Fume composition and spatter/fire behavior can change. | Review extraction, filtration, housekeeping, and exposure-control assumptions. |
| Robot path or fixture | Reflection direction and access points may move. | Retest interlocks and update the cell layout drawing. |
