TOXIC MATERIALS. Exposure to certain types
of fumes can result in serious, potentially deadly
health effects. To reduce this risk, research toxic-
ity of material types you work with, and always
seek to minimize/eliminate exposure to yourself
and others. Obtain the Safety Data Sheet (SDS)
from material manufacturer BEFORE operations,
and never knowingly engrave or cut a workpiece
that has been treated with or contains material
that releases toxic byproducts when heated.
TOXIC FUMES. Cutting or engraving metals and
plastics give off highly toxic fumes, vapors, and air
particulates containing zinc, lead, beryllium, cad-
mium, mercury, fluorine, hexavalent chromium,
chlorine gas, and many others. These fumes
and air contaminants can damage the machine
and harm your health. If the fume extractor or
extraction fan is malfunctioning, immediately stop
operations and correct the issue.
ADEQUATE VENTILATION. Only use CNC
lasers in spaces with adequate ventilation. Some
materials can produce vapors and fumes that may
irritate the nose, throat, and respiratory tract, or
cause suffocation. Only operate CNC lasers with
a fully functioning extraction fan and fume extrac-
tor. Use additional personnel to monitor operator
from outside the operating area in the event of
equipment failure.
EXTRACTION FAN. To effectively extract fumes
and particulates from the machine during opera-
tions, use an extraction fan rated for a minimum
of
200 CFM (Cubic Feet per Minute) at 6" static
pressure.
Long-term respiratory damage, toxicity, cancer, or birth defects can occur from inhaling fumes,
vapors, and particulates generated while cutting substrates without adequate ventilation,
exhaust, and fume extraction. All users must be properly trained on the potential hazards,
control measures, manufacturer’s operating procedures, use of personal protective equipment
(PPE), emergency procedures, and safety precautions for CNC laser operations. To reduce
these risks, operator and bystanders MUST completely heed the warnings below.
FUME EXTRACTION. CNC lasers must be
equipped with a fume extractor that uses MERV
15+ or HEPA filters. NEVER modify fume extrac-
tor or bypass safety features. Only operate fume
extractor with all filters and covers in place dur-
ing operation. If any filter is missing or has been
replaced with a non-specification filter, the fume
extractor will not properly filter contaminated air
and will be unsafe to use.
INSPECTIONS/MAINTENANCE. Always inspect
exhaust ducting and fume extractor for leaks prior
to operations. Repair or replace defective compo-
nents before starting.
FILTER CLEANING/DISPOSAL. Filters must
be changed regularly according to the frequency
of use, or as specified by the manufacturer.
When servicing filters, make sure operator and
any bystanders are wearing Personal Protective
Equipment (PPE). When vacuuming filters and
cabinet, only use a shop vacuum that is equipped
with a MERV 15+ or HEPA filter, or dangerous
particulates may be spread throughout the area
and contaminate the air. Wrap all waste filters in
air-tight plastic bags, then mark and dispose of
according to current laws and regulations.
EXPERIENCING DIFFICULTIES. Keep in mind
that CNC laser hazards are intensified in a con-
fined space. If you are experiencing difficulties
performing the intended operation, stop using the
equipment, and contact the Occupational Safety
and Health Administration (OSHA) at (800) 321-
6742, or online at
www.osha.gov to find out how
to design and maintain the best overall CNC laser
toxic fume extraction system for your needs.
