1.6 FIRE OR EXPLOSION HAZARD
Arc welding and allied processes can cause fire
and explosions. Precautions should be taken
to prevent these hazards.
1.6.1 Fire hazard
• Before setting to perform welding opera-
tions, ensure that elements involving fire
hazard are removed from the zone where
welding operations will take place. If it is
impossible, protect all flammable elements
against the impact of sparks. Remember
that sparks and hot metal may penetrate
through small cracks and openings into the
adjacent area.
• Avoid welding in the vicinity of hydraulic
conduits.
• The welding arc throws sparks and splatters
out. Welders should wear clean and dry
protective clothing (staining with oil should
be avoided in particular) such as welding
gloves, welder’s apron, welder’s trousers,
welder’s boots, protective hood/cap, etc.
• When welding operations are not carried
out, make sure that no part of the electrode
comes into contact with the workpiece or
protective earthing. Accidental contact may
lead to overheating and create a fire hazard.
• The fire extinguisher should be ready for use
and located in an easily accessible place.
• The surroundings of the work should be
observed for an adequate period after its
termination.
• „Hot spots” and immediate surroundings
should be observed until their temperature
has dropped to normal.
1.6.2 Explosion hazard
It is forbidden to heat up, cut or weld tanks,
barrels or containers that contained toxic or
flammable materials. For there is an explosion
hazard, even if the containers have been emp-
tied and cleaned.
1.6.3 Use of cylinders with shielding gas
In case compressed gases are used in the work
place, apply special safety measures to prevent
dangerous situations.
• Use gas cylinders with appropriate shielding
gas, foreseen for a particular process. Addi-
tional equipment (pressure regulator, hoses,
connectors) should be in good technical
condition. A gas cylinder and accessories
should have the required valid attestations
and approvals for use.
• Gas cylinders should always be stored in
vertical position, fixed to an undercarriage
or permanent support.
• Gas cylinders should be placed far away
from areas, where they could be exposed
to the risk of being overthrown or suffering
physical damage.
• Ensure gas cylinders are at a safe distance
from places where electric welding or cut-
ting operations are to be performed, away
from other sources of heat, sparks or flames.
• Care shall be taken to prevent gas cylinders
in the vicinity of the workpiece becoming
part of the welding circuit.
• Never allow the electrode, electrode holder
or any other live electric part to get in con-
tact with the gas cylinder.
