⚠️ Quick Answer: Industrial Laser Safety
All industrial cutting/welding lasers (>500mW) are Class 4 - the highest hazard level. Requires full enclosure, interlocks, OD 5-7 eyewear, and Laser Safety Officer (LSO) designation.
Determine your laser safety classification per IEC 60825-1:2014 and ANSI Z136.1-2022 standards. Get required protective measures and labeling requirements.

| Class | Power/Energy Limit | Hazard Level | Required Controls |
|---|---|---|---|
| Class 1 | < 0.39 mW (visible) | Minimal | No special controls - inherently safe |
| Class 2 | < 1 mW (visible only) | Low | Warning labels, avoid staring into beam |
| Class 3R | < 5 mW (visible) | Moderate | Warning signs, limit direct exposure, training |
| Class 3B | < 500 mW | High | Laser eyewear (OD 4+), controlled area, key switch |
| Class 4 | > 500 mW (all industrial) | Extreme | Full enclosure, interlocks, LSO, OD 5-7 eyewear, fire suppression |
| Laser Type | Wavelength | Minimum OD | VLT Consideration |
|---|---|---|---|
| Fiber Laser | 1064-1080 nm | OD 5+ (typical OD 6-7) | High VLT possible (70%+) |
| Nd:YAG | 1064 nm | OD 5+ (typical OD 6) | High VLT possible |
| CO₂ Laser | 10600 nm | OD 5+ (typical OD 5-6) | Clear lenses available |
| Green Laser | 532 nm | OD 4-5 | Lower VLT (orange/red tint) |
OD = Optical Density. OD 5 = blocks 99.999% of radiation. Always verify eyewear rating matches your exact wavelength.
A 6kW fiber laser (1070nm) is definitively Class 4 - the highest hazard class. Class 4 lasers can cause immediate eye injury from direct or reflected beams, skin burns, and fire hazards. Required safety measures include: full enclosure with interlocks, laser safety eyewear (OD 6+ at 1070nm), LSO designation, key switch control, warning signs, and written safety procedures. All industrial cutting and welding lasers above 500mW are Class 4.
⚠️ Important: This tool provides estimates based on IEC 60825-1:2014 simplified thresholds. Actual safety classification requires detailed analysis including pulse parameters, beam divergence, and viewing conditions. Always consult a qualified Laser Safety Officer (LSO) and refer to official standards (IEC 60825-1, ANSI Z136.1) for compliance.
