Woodshop Dust Fire Safety Considerations*
Before processing materials the user must verify whether harmful materials can be generated
and whether the lter equipment of the exhaust system is suitable for the harmful materials. We
emphasize that it is the responsibility of the user to consider the national and regional threshold
values for dust, fogs and gases when selecting the lters and the exhaust system.
(The values for the maximum workplace concentration must not be exceeded.)
Be mindful of large quantities of fuel in the form of wood and wood products, sawdust, and
ammable materials such as paints, oil nishes, adhesives, solvents, and liquid propane for
internal combustion engines.
Preventing the buildup of dust is one of the key means for controlling re and explosion hazards.
The principal engineering control technology for control of dust is exhaust ventilation. The primary
work practice control is good housekeeping.
Dust collection is best accomplished at the source-at the point of operation of the equipment, if
feasible. For many pieces of equipment, well-designed ducts and vacuum hoods can collect most
of the dust generated before it even reaches the operator.
Very ne dust that manages to escape point-of-source collection can be captured from above by
general exhaust points located along the ceiling. These control technologies are effective for most
equipment, excepting machines that commonly produce the very nest dust or large quantities of dust.
*These guidelines come from the U.S. Department of Labor
NEVER CUT PVC (polyvinyl chloride) under any circumstances: fumes are highly toxic
and potentially lethal.
NEVER store any ammable materials in the inside of the device or in the immediate vicinity of
the device. Debris and leftover produced materials within the machine must to be removed to prevent
re hazard.
ALWAYS have on hand a rst-aid kit designed for the initial treatment of burns and smoke
inhalation. Be sure to store this kit in an area that is outside risk areas.
