2026 baseline
Laser Safety Standards Matrix
Current safety references and how each one supports equipment, workplace controls, and documentation.
DecisionControl layer
Map each standard family to product classification, machine guarding, or workplace controls.
Release packageCell file
Keep enclosure, interlock, eyewear, fume, signage, and training evidence together.
Recheck whenAny change
Power, wavelength, optics, enclosure, material, or service mode changes can alter controls.
Use the 2026 baseline to assign each safety decision
Laser welding safety records should separate product classification, laser processing machine safeguards, facility laser safety rules, and workplace welding controls. This matrix maps each reference to the decision it supports without treating any single document as a complete cell authorization.
- Classify the laser product and operating mode before cell trials.
- Verify enclosure, interlocks, beam containment, eyewear, extraction, access, and training as one package.
- Recheck the package after changes to wavelength, optics, path, enclosure, material, or service mode.

Use this matrix to keep safety records aligned with the current public baseline used by WeldingCalc pages.
| Reference | Primary use | Planning output | When to recheck |
|---|---|---|---|
| GB/T 7247.1-2024 | China laser product safety classification and equipment requirements. | Laser class, marking, user information, and China-market safety file inputs. | Source, class, emission mode, label set, or product documentation changes. |
| IEC 60825-1:2014 | International laser product equipment classification and requirements. | Product class, accessible emission basis, warning labels, and user-safety information. | Wavelength, accessible emission, protective housing, interlock, or service condition changes. |
| ISO 11553-1:2020 | Laser processing machine safety requirements for hazards caused by laser radiation. | Enclosure, guards, interlocks, viewing paths, beam stops, and machine risk-reduction controls. | Optics, fixture, robot path, enclosure, viewing window, or service procedure changes. |
| ANSI Z136.1-2022 | US laser safety program reference for safe use of lasers. | Controlled area, eyewear basis, administrative controls, hazard evaluation, and training records. | Laser source, operating mode, authorized personnel, service state, or facility layout changes. |
| OSHA 1910 Subpart Q | US workplace welding, cutting, and brazing control baseline. | Ventilation, fire prevention, access, operator protection, and workplace procedure records. | Material, coating, ventilation, fire exposure, operator position, or workplace procedure changes. |
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 trigger a safety review
| Change | Why it matters | Review scope |
|---|---|---|
| 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. |
