1-2. 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 instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-6. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
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 may ignite and cause
fire and explosion.
D 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 equipment label and consult your Safety Director
and a certified Industrial Hygienist.
D Follow all applicable ANSI, OSHA, CSA, UL, and other regulatory
guidelines pertaining to the use of fume extractors and the
recirculation of filtered air.
D Portions of fume collection equipment, including the clean- and
dirty-air plenums, may be considered OSHA Confined Spaces.
Refer to the appropriate OSHA regulations to determine if a
specific installation is a confined space and if a permit program is
required.
D 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 may
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.
D 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,
aggressive fumes (acid), fumes from burning objects, or fumes
from cleaning, cutting, gouging, grinding, painting, flame spraying,
sand blasting, or other non−welding operations.
D Fumes from some welding operations may be combustible. Do not
install or operate fume extractor where combustible weld fumes
may be present unless a fire/and/or explosion protection system is
present that has been selected and approved by a qualified person
familiar with applicable codes and fire/explosion protection
systems.
.
Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-
bols and related instructions below for necessary actions to avoid the
hazards.
D Use the fume extractor only in atmospheres for which it is
recommended. Do not use the extractor where contaminant levels
are unknown or are immediately dangerous to life, or where the
contaminant levels exceed the fume extractor specifications.
D Do not weld until you are sure the fume extractor is correctly
assembled and working properly.
D Before each use, inspect the fume extractor for damage and verify
it operates properly.
D Dangerous contaminants may not smell or be visible. Leave the
area immediately if you notice 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.
D 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.
D Replace damaged or clogged filter. 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 may be damaged). Do not breathe the dust collected by
the fume extractor. Wear approved safety equipment (respirator,
gloves, long sleeve shirt) when performing filter maintenance.
Dispose of used filter element and collected dust according to
local, state, and federal requirements.
D Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer's instructions for metals, consumables,
coatings, cleaners, and degreasers.
D The fume extractor must be used with the extraction arm, hoses,
filter, and other components recommended by the manufacturer.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The input power circuit and machine
internal circuits are also live when power is on.
Incorrectly installed or improperly grounded equip-
ment is a hazard.
D Do not touch live electrical parts.
D Disconnect input power before installing or servicing this equip-
ment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
D Properly install, ground, and operate this equipment according to
its Owner's Manual and national, state, and local codes.
D Always verify the supply ground − check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
