⚠️ Laser Safety Guide
Essential safety information for laser cutting. Your safety and the safety of others should always be your top priority.
🚨 CRITICAL SAFETY WARNING
NEVER cut these materials: PVC, Vinyl, Polycarbonate, ABS (thick), or any chlorinated plastics. They produce deadly chlorine gas.
NEVER leave your laser unattended during operation. Fires can start in seconds.
ALWAYS have proper ventilation and fire safety equipment ready.
✅ Pre-Operation Safety Checklist
Before Every Use:
- ☐ Fire extinguisher within reach
- ☐ Ventilation system running
- ☐ Material identified and verified safe
- ☐ Work area clear of flammables
- ☐ Emergency contacts posted
- ☐ Safety glasses on
Machine Check:
- ☐ Laser bed clean
- ☐ Optics clean and aligned
- ☐ Air assist functioning
- ☐ Emergency stop accessible
- ☐ Enclosure doors secure
- ☐ Exhaust fan operational
Material Safety Guide
Low Risk Materials
Safe to Cut:
- • Solid wood (not treated)
- • Paper and cardboard
- • Natural leather
- • Cotton and natural fabrics
- • Food-grade acrylic
- • Cork
Precautions: Basic ventilation, fire watch, clean workspace
Medium Risk Materials
Use with Caution:
- • MDF and plywood
- • Synthetic fabrics
- • Painted materials
- • Treated woods
- • Some foams
- • Engraving metals
Precautions: Enhanced ventilation, respiratory protection, test cuts
High Risk Materials
NEVER Cut:
- • PVC / Vinyl (chlorine gas)
- • Polycarbonate (toxic)
- • ABS plastic (thick)
- • Fiberglass
- • Any unknown materials
- • Reflective metals
Danger: Toxic gases, fire hazards, laser damage risk
🧪 Unknown Material Testing Protocol
Before Cutting:
- 1. Research material composition
- 2. Check manufacturer safety data sheets
- 3. Test on tiny sample in well-ventilated area
- 4. Monitor for unusual smells or colors
- 5. Stop immediately if concerned
Warning Signs:
- • Strong chemical odors
- • Yellow or green smoke
- • Excessive melting instead of cutting
- • Sparking or flashing
- • Corrosive residue
Essential Safety Equipment
🔥 Fire Safety
Required Equipment:
-
•
Fire Extinguisher
Class A, B, C rated. Within 10 feet of laser. -
•
Water Spray Bottle
For small flare-ups on wood/paper. -
•
Smoke Detector
Early warning system above workspace. -
•
Emergency Plan
Posted evacuation and contact info.
🛡️ Personal Protection
Protective Gear:
-
•
Laser Safety Glasses
Wavelength-specific protection. -
•
Respiratory Protection
N95 minimum, P100 for toxic materials. -
•
Heat-Resistant Gloves
For handling hot materials safely. -
•
Appropriate Clothing
Natural fibers, no loose sleeves.
📊 Monitoring
Safety Monitoring:
-
•
Temperature Monitor
Infrared thermometer for hot spots. -
•
Air Quality Monitor
VOC detection for harmful fumes. -
•
Camera System
Remote monitoring capability. -
•
Timer/Alarm
Alerts for long operations.
Ventilation Requirements
🌪️ Exhaust Ventilation
Minimum Requirements:
- • 200+ CFM exhaust fan
- • Direct external venting
- • No recirculation of air
- • Backdraft damper installed
- • Regular filter maintenance
Best Practice: Exhaust fan should run 24/7 when laser is in use and for 30 minutes after.
💨 Air Flow Management
Air Flow Design:
- • Negative pressure in work area
- • Fresh air intake opposite exhaust
- • No dead air pockets
- • Consistent airflow across bed
- • Air assist for cutting aid
Test Method: Use smoke test to verify proper air flow patterns.
🔍 Filtration Options
Pre-Filter
Removes large particles and protects main filter.
- • Washable mesh
- • Replace monthly
- • Low cost maintenance
HEPA Filter
Captures 99.97% of particles 0.3μm and larger.
- • Essential for fine dust
- • Replace every 6-12 months
- • Monitor pressure drop
Carbon Filter
Absorbs odors and volatile organic compounds.
- • Critical for odor control
- • Replace every 3-6 months
- • Material-dependent lifespan
Emergency Procedures
🔥 Fire Emergency
Immediate Actions:
- 1. STOP LASER IMMEDIATELY - Hit emergency stop
- 2. DO NOT OPEN ENCLOSURE - Oxygen feeds fire
- 3. Turn off air assist - Reduces oxygen flow
- 4. Call emergency services if fire spreads
- 5. Use appropriate extinguisher if safe to do so
- 6. Evacuate if necessary - Life over property
Never use water on electrical fires or burning oils/plastics.
🏥 Medical Emergency
Fume Exposure:
- 1. Move to fresh air immediately
- 2. Call Poison Control if symptoms present
- 3. Seek medical attention for severe symptoms
- 4. Provide material information to medical staff
Laser Eye Exposure:
- 1. Do not rub eyes
- 2. Seek immediate medical attention
- 3. Document laser wavelength/power
Emergency Contacts: Keep Poison Control (1-800-222-1222) and emergency services readily available.
