Laser Cutter & Facilities

Laser Cutter – Fire Hazard

Please be aware there was an issue where a laser cutter caught fire, the machine itself was LS6090 Pro. Could we please ask that you check that all laser machine equipment is up to date on its service and any faults are logged and resolved. Could we also ask that teaching staff observe the guidelines and not leave these types of machines running and unattended.

Control Measures

• It is essential that the interlock, fitted to prevent laser operation unless the system is enclosed, must not be over-ridden. (This is necessary to make the system into a Class 1 device, which may be used in schools.)
• Never leave laser cutter to run unattended, because of the risk of fire.
• At the end of each job, clean work, and waste material from the work bed.
•  Servicing should be restricted to authorised and trained personnel to control the high voltage risk as well as risks from the beam.
• Do not cut PVC and polyurethane foams, even with LEV in use.
•  Other materials require efficient dust and fume control. Suppliers may recommend special filters for certain tasks, e.g., cutting rubber.
• Set the power setting and speed of cut correctly to minimise the risk of ignition of the workpiece. Where possible the space between cuts should be kept to at least the thickness of the material being cut.

Below are data sheets for the model that caught fire, along with the guidelines from CLEAPSS. Please click on the images for full screen view.
