Laser Room/Precautions

Safety

• Hazards: fumes, fire, noise, lacerations.
• Wear hearing protection when the exhaust fan is on, as it's loud enough to cause hearing damage.
• Check the debris tray before and after. Debris buildup can cause a fire as the laser cuts through the workpiece and enters the debris tray.
• Do not cut unknown or unapproved materials. If the material is not on the approved list, ask for permission on Slack.
• Heat can build up when doing multiple passes on wood, causing the material to ignite. If you're cutting thick wood and it doesn't go through in three passes, stop.
• Always use a vector grid when cutting all the way through.
• Don't wear loose hair, clothing, jewellery, etc. as they can become entangled in the belts.

Housekeeping

• When using Big Blue, Little Blue, and Big Red: Clean the lens before the start of your session. Monitor the lens throughout - cutting messy materials like rubber may require recleaning. Note that Big Red has one extra mirror that needs to be cleaned in addition to the one in the head.
• When using Giant Blue, check the lens frequently for debris buildup and clean as required.
• Always use a lens tissue when cleaning the lens - bare Q-tips can
• Break down waste before bagging (pieces should be smaller than 6" x 6"). Blunt any sharp edges so they don't break the bag.
• The Blue Laser Room vacuum is located by Big Red for your use.
