1.4 Fire Warning
Your laser system uses a high intensity beam of light that can generate extremely high temperatures when it comes into
contact with the material being engraved or cut. Some materials are extremely flammable and can easily ignite and burst
into open flame, setting the machine afire. This open flame is very dangerous and has the potential to destroy not only
the machine, but also the building in which it is stored.
Experience shows that working with the laser has a large potential to create an open flame. Many materials are susceptible
to igniting, but acrylic, in all its different forms, has been shown to be especially flammable when vector cutting with the
laser.
Please read the warnings and recommendations and follow them closely at all times!
• Stay with the laser. Never operate the laser system while unattended.
• Clean the area of and around the machine. Keep the area free of clutter, combustible materials, explosives or
volatile solvents such as acetone, alcohol or gasoline.
• Be prepared with a fire extinguisher. Always keep a properly maintained and inspected fire extinguisher on
hand. STEPCRAFT recommends a Halotron fire extinguisher or a multi-purpose dry chemical fire extinguisher.
The Halotron extinguishers offer certain advantages should you ever need to use an extinguisher. The Halotron
extinguisher discharges a clean, easily removable substance that is not harmful to the mechanics or wiring of
the laser system. The dry chemical extinguisher discharges a sticky, corrosive powder that is very difficult to
clean up.
