DANGER: Sanding/finishing wood floors can create an environment that can be explosive. The

following safety procedures must be adhered to:

• Cigarettes, cigars, pipes, lighters, pilot lights and any other source of ignition can create
an explosion when active during a sanding session. All sources of ignition should be
extinguished or removed entirely from the work area.

• Work areas that are poorly ventilated can create an explosive environment when certain
combustible materials are in the atmosphere, i.e., solvents, thinners, alcohol, fuels,
certain finishes, wood dust and other combustible materials. Floor sanding machines
can cause flammable material and vapors to burn. Read the manufacturer's label on all
chemicals used to determine combustibility. Keep the work area well ventilated.

• Spontaneous combustion or an explosion can occur when working with sanding dust.
The sanding dust can ignite and cause injury or damage. Sanding dust should be
disposed of properly. Always empty the sanding dust into a metal container that is
located outside of any building.

the dust bag each time you finish using the machine.
with sanding dust in it.

• Do not empty the contents of the dust bag into a fire.

• Hitting a nail while sanding can cause sparks and create an explosion or fire. Always
countersink all nails before sanding floors.

Never leave a dust bag unattended
