Hazards

• Fire/Hot objects

  • During operation, substrate material is burned away, generating significant amounts of heat.

  • Some materials can catch fire during cutting operations.

  • Dirt and debris may cause fire.

• Hazardous vapors and fumes & Exhaust Systems

  • Cutting specific material there is potential to produce Laser Generated Air Contaminants (LGAC’s). Contaminants can pose a health risk to those exposed; examples airborne benzene, toluene, hydrochloric acid, isocyanates, and other by-products which maybe hazardous.

  • Laser cutter MUST be exhausted via FP&M approved duct work to the outside of the building.

  • Exhaust systems must be installed properly and meet all manufacturer specifications.

• Other Hazards:

• Exposure to laser beam can cause severe eye damage or skin burns.

• Sharp edges could result in lacerations, and puncture wounds.

Signage

Warning signs are necessary to inform about the risk of exposure during use and maintenance. Signs are available from EH&S Radiation Safety Office.

Training

All users should receive training on the potential hazards, operating procedures, and safety precautions before operating the laser cutter.

Safety Considerations

• NEVER operate system unattended.

• Properly maintained fire extinguisher should always be in the area.

• Always keep the area around cutter free of debris, clutter, and flammable materials.

• Keep interior of the laser cutter clean and free of debris. Visually inspect the interior between uses and clean tray if debris or residue are present.

• DO NOT modify or disable any safety features of the laser system.

• DO NOT operate the laser unless all covers are in place and interlocks are working properly.

• DO NOT look directly into laser beam.

• DO NOT view directly with optical instruments.

• Use accepted materials only. Some materials engraved, marked, or cut with the laser can produce toxic and corrosive fumes.

• DO NOT operate if the view port is damaged, with any doors removed, or if any safety interlocks are defeated

• NEVER defeat laser interlocks built into the cutter. This could allow the beam to escape the laser cutter.
