Laser safety signs are critical visual safeguards that protect operators from radiation, electrical hazards, and operational risks.
For ChinaCNCZone handheld laser welder users, understanding these warnings ensures compliance with ANSI Z136.1 and ISO 7010 standards while preventing accidents.
Here’s a breakdown of key signs and their life-saving implications.
1. Mandatory Action Signs (Blue Circles)
| Sign | Meaning | Consequence of Ignoring |
|---|---|---|
| ![Laser Goggles] |
Wear Laser-Specific Eyewear OD 7+ protection for 1,070nm wavelength |
Retinal burns within 0.25 seconds |
| ![Gloves] | Fire-Resistant Gloves Required | 3rd-degree burns from molten metal spatter |
| ![Ventilation] | Fume Extraction Mandatory | Toxic metal fume inhalation (e.g., Cr⁶⁺) |
2. Prohibition Signs (Red Circles with Slash)
| Sign | Hazard Prevented |
|---|---|
| ![No Bypass] |
Never Bypass Safety Interlocks Prevents accidental laser activation |
| ![No Touch] |
Do Not Touch Optics Avoids coating damage from skin oils |
| ![No Water] |
Water Prohibited on Electrical Fires Use CO₂ extinguishers only |
3. Warning Signs (Yellow Triangles)
| Sign | Risk | ChinaCNCZone’s Mitigation |
|---|---|---|
| ![Laser Radiation] |
Invisible IR Radiation Class 4 laser hazard |
Internal beam traps + 15° tilt auto-shutoff |
| ![High Voltage] | Lethal 220V/380V Circuits | Double-insulated cables + ground fault detection |
| ![Hot Surface] | 150°C+ Nozzle Surfaces | Post-weld cooldown timer (60s) |
| ![Metal Fumes] | Carcinogenic Fumes | Integrated fume extraction port (Ø40mm) |
4. Emergency & First Aid Signs (Green Squares)
| Sign | Action Required |
|---|---|
| ![Emergency Stop] |
Cut Power Immediately For beam misalignment/fire |
| ![Eye Wash] |
Flush Eyes Within 30s If laser exposure suspected |
| ![First Aid] |
Burn Treatment Station For thermal/UV injuries |
