Fume Extraction Hazards

The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instruc-
tions to avoid the hazard. The safety information given be-
low is only a summary of the more complete safety
information found in the Principal Safety Standards listed in
Section 1-6. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain,
and repair this equipment. A qualified person is defined as
one who, by possession of a recognized degree, certificate,
or professional standing, or who by extensive knowledge,
training and experience, has successfully demonstrated the
ability to solve or resolve problems relating to the subject
matter, the work, or the project and has received safety
training to recognize and avoid the hazards involved.
During operation, keep everybody, especially children,
away.
FUME EXTRACTOR MISUSE can be
hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health. Combustible materials can ignite and
cause fire and explosion.
� Read and follow these instructions and the safety labels carefully.
The fume extractor helps protect the user from specific airborne
contaminants but must be used correctly to be fully effective. Have
an industrial hygienist test the air in your facility to ensure the fume
extractor provides adequate protection from contaminants in your
environment. If you have questions about the extractor, see equip-
ment label and consult your Safety Director and a certified Indus-
trial Hygienist.
� Follow all applicable ANSI, OSHA, CSA, UL, NFPA and other reg-
ulatory guidelines pertaining to the use of fume extractors and the
recirculation of filtered air.
� Portions of fume collection equipment, including the clean- and
dirty-air plenums, can be considered OSHA Confined Spaces. Re-
fer to the appropriate OSHA regulations to determine if a specific
installation is a confined space and if a permit program is required.
� Do not use the fume extractor without an approved and properly
installed spark guard unless the unit is designed and intended to
be used without one. Without the spark guard, welding sparks can
ignite a non-fire retardant filter or fume collected on the filter, or
damage the filter and allow unfiltered air into the breathing zone.
Do not allow sparks or any burning materials to enter the hood or
duct of the fume extractor.
� Only use the fume extractor to extract weld fumes. Do not use the
fume extractor to extract hot gases (above 140°F/60°C) wood or
cement dust, engine exhaust, liquid vapors, explosive materials,
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult
symbols and related instructions below for necessary actions to
avoid these hazards.
aggressive fumes (acid), fumes from burning objects, or fumes
from cleaning, cutting, gouging, grinding, painting, flame spraying,
sand blasting, or other non-welding operations.
� Fumes from some welding operations can be combustible. Do not
install or operate fume extractor where combustible weld fumes
can be present unless a fire/and/or explosion protection system is
present that has been selected and approved by a qualified per-
son familiar with applicable codes and fire/explosion protection
systems.
� Use the fume extractor only in atmospheres for which it is recom-
mended. Do not use the extractor where contaminant levels are
unknown or are immediately dangerous to life, or where the con-
taminant levels exceed the fume extractor specifications.
� Do not weld until you are sure the fume extractor is correctly as-
sembled and working properly.
� Do not position the fume extractor hood in any location that will al-
low the weld fumes to be pulled into the operator's breathing zone.
� Minimize cross drafts that affect fume extraction by closing doors/
windows and/or installing weld screens/curtains.
� Before each use, inspect the fume extractor for damage and verify
it operates properly.
� Dangerous contaminants may not smell or be visible. Leave the
area immediately if you notice any of the following:
a. Breathing becomes difficult.
b. You experience dizziness, impaired vision, or eye, nose, or
mouth irritation.
c. The equipment is damaged.
d. Air flow decreases or stops.
e. If you think the equipment is not supplying adequate protection.
� Do not repair, modify, or disassemble the fume extractor or use
with parts or accessories not supplied by the manufacturer. Use
only approved components from the manufacturer.
� Replace damaged or plugged filter. Allow cooling period before in-
specting or replacing filter, or cleaning particle tray and spark
guard. Do not wash or reuse filter, or clean filter by tapping or with
compressed air, unless specifically instructed by the manufacturer
in the Owner's Manual (filter element can be damaged). Do not
breathe the particles collected by the fume extractor. Wear ap-
proved safety equipment (respirator, gloves, long sleeve shirt)
when performing filter maintenance. Dispose of used filter element
and collected particles according to local, state, and federal
requirements.
� Read and understand the Safety Data Sheets (SDSs) and the
manufacturer's instructions for adhesives, coatings, cleaners, con-
sumables, coolants, degreasers, fluxes, and metals.
� The fume extractor must be used with the extraction arm, hoses,
filter, and other components recommended by the manufacturer.
