Fire Safety
Laser cutting and engraving systems represent a significant fire hazard. Most
engraving materials are inherently combustible, and while the objective of most
cutting and engraving operations is to vaporize material without burning, it is easy
to ignite a flame. Usually this is a simple “flare” of burning gases, issuing from
the focused spot on the work piece, which follows the moving spot and which
extinguishes itself as soon as the laser beam is modulated off. But should the
work piece actually be set on fire, the fire must be extinguished by the operator at
once, or the machine will be seriously damaged or destroyed!
Experience shows that vector cutting with the laser has the most 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 following warnings and recommendations and follow them closely
at all times!

NEVER
let the laser system operate if it will be unattended.

KEEP
the area around the machine clean and free of clutter, combustible
materials, explosives, or volatile solvents such as acetone, alcohol, or
gasoline.

ALWAYS
keep a properly maintained and inspected fire extinguisher on
hand. Epilog recommends a Halotron fire extinguisher or a multi-purpose
dry chemical fire extinguisher. The Halotron extinguishers are more
expensive than a dry chemical, but 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.

ALWAYS
use air assist when vector cutting.

BE CAREFUL
! when vector cutting. Many materials have the potential to
burst suddenly into flames – even materials that may be very familiar to
the user. Always monitor the machine when it is operating.

KEEP YOUR LASER SYSTEM CLEAN
– A build up of cutting and
engraving reside and debris is dangerous and can create a fire hazard in its
own right. Keep your laser system clean and free of debris. Regularly
remove the vector grid to clean any small pieces that have fallen through
the grid.
