You must not use the laser cutter without being inducted first. Improper use can cause serious damage to the machine. The laser has a Tool Control system that will only turn the laser on for inducted users.

  • How to get inducted - general overview of the procedure for all inductions
  • Add yourself to the waiting list
  • See upcoming inductions - list view | calendar view - you will need to login to see these

Inductors: Here is a suggested induction presentation (status: mature - been used for several inductions).

Risk Assessment

Description of Task
Using a high powered computer controlled laser burning process to cutting blank stock material such as wood and plastic to a pattern from a digital file.

Hazard Risk Rating Control Measure Residual Risk
Fire Low Users required to use approved materials only, correctly set speed & power settings for the material and never leave machine running unattended. CO2 fire extinguisher provided. Very Low
Exposure to laser light Low Machine enclosed and lid fitted with interlock not to be overridden, according to Type 1 laser regulations. Very Low
Electrocution Low Servicing restricted to authorised and trained personnel. Very Low
Harmful/toxic fumes Low Users advised to use approved materials only. Strictly no PVC or polyurethane foams. Very Low

Disposal

  • The fume and dust-control systems must be properly maintained, tested annually and the filters changed according to the manufacturer’s instructions. Used filters should be sealed into strong plastic bags before placing them in the waste.
  • Cleanup and machine maintenance must be performed as described in the induction

Getting help

  • Contact @lasertechs on Discourse if you are having any problems with the machine.
