6. Compressed gas cylinders
are potentially dangerous. Consult the supplier
for correct handling procedures. Always protect
compressed gas cylinders from the sun’s rays,
flames and sudden temperature changes.
1.3 FIRE AND EXPLOSION PREVENTION
Hot slag and sparks can
cause fire. The risk of fire and explosion can be
minimized by removing all flammable material
from the welding area.
1. Always perform welding operation with cau-
tion. Containers and tubes that have been
emptied and thoroughly cleaned still repre-
sent a potential hazard.
2. Never perform welding operations or cut a
closed container or pipe.
3. Never perform welding operations on open
containers or pipes that may have been con-
taminated with substances that could explode
or react when exposed to heat or humidity.
4. As a preventative measure, keep fire extin-
guishers near the welding operation.
1.4 METAL FUME HAZARDS
Welding fumes and gases may be haz-
ardous if inhaled.
1. Install a ventilation system in the welding
area.
2. Use a forced air system when welding lead,
beryllium, cadmium, zinc, zinc-coated or
painted material. Always wear a protective
mask.
3. If the ventilation system is inadequate, use an
air respirator.
4. Beware of gas leaks. Shielding gases such as
argon are heavier than air and when used in
small spaces, will replace the air.
5. In the event that a welding operation occurs in
a confined place, the operator should be
accompanied by another person.
6. Always keep gas cylinders in a well-ventilated
area. Close the main gas valve when cylinder
is not in use.
7. Do not perform welding operations near chlo-
rinated hydrocarbon vapors produced by
degreasing or painting. The heat generated
by arc rays can react to form phosgene, a
highly toxic gas.
8. Irritation of the eyes, nose and throat are
symptoms of inadequate ventilation. Take
immediate steps to improve ventilation. Do
not continue welding if symptoms persist.
1.5 TRANSPORTING THE POWER SOURCE
1. The welding machine may be carried by the
handle.
2. Always disconnect the power source and
accessories from the main supply before lift-
ing or handling the welding equipment.
3. Do not drag, pull or lift welding equipment by
the weld cables.
1.6 MAGNETIC FIELDS CAN AFFECT
PACEMAKERS
1. Keep pacemaker wearers away
from welding operations.
2. Pacemaker wearers should consult with a
physician prior to being exposed to any weld-
ing or cutting operation.
