Laser Cutter Safety

Laser cutters require special ventilation. It is important to contact EHS before purchasing a laser cutter or engraver to discuss ventilation options and registration requirements.

Laser cutters use a powerful laser for precise cutting and engraving. The hazards associated with a laser cutter include the possibility of fires and the generation of hazardous and/or irritating combustion products. The laser cutter high powered laser can cause damage to eyes and skin, and it must be contained within the cutter.

When purchasing a laser cutter be sure to purchase a unit that has “air assist”. This feature is optional and important for preventing fires (and also helps to make cleaner cuts). Existing and new laser cutter/engraver(s) must be registered. Contact the MIT EHS Office, environment@mit.edu, to register and inventory your laser cutter/engraver(s).

Best Practices for Safe Operation

  • Before using a laser cutter, be sure you have been trained by a qualified individual. A written procedure covering laser cutter use is recommended.
  • Always follow the manufacturer’s instructions when operating a laser cutter.
  • Keep a logbook detailing who has used the laser cutter, cutting time, and materials cut.
  • A fire extinguisher should be mounted on the wall near the laser cutter.
  • Regular vacuuming of the cutting deck and the internal cavity of the laser cutter is very important for preventing fires!
  • Know what materials can be safely cut! Some materials such as PVC produce hydrogen chloride gas which is extremely dangerous. If you are unsure if your material is safe to cut, contact your EHS Coordinator or the MIT EHS Office at 617-452-3477.
  • Never leave an operating laser cutter unattended.
  • Avoid placing the laser cutter on wood and other combustible surfaces.
  • Know how setting the pulse rate of the laser affects the chance of a fire and the resolution of the cut.
  • Never defeat laser interlocks built into the cutter. This could allow the beam to escape from the laser cutter.
