• Do not weld at locations close to grease, cleansing or jet
painting operations. The heat and the arc rays can make a
reaction with the vapor and create highly toxic and irritating
gas.
• Do not weld on coating materials like galvanized steel, lead
or cadmium coated steels, unless the coating is removed
from the welding area, the area has a proper ventilation
and there is a working respirator with air source. Coatings
of any metal that contains those elements may emanate
toxic smoke and gases when welded.
ARC RAYS can burn your eyes and skin
Arc rays from a welding process produce an intense heat and
strong UV rays that can burn the eyes and skin.
• Use the approved welding mask that has an appropriate
trace of lens-filter to protect your face and eyes while
welding or observing. Look at the safety standards
ANSI Z49.1, Z87.1, EN175 and EN379.
• Use approved safety lenses that have side protection.
• Use protection screens or barriers to protect others from
reflections and sparks. Tell others not to look at the arc.
• Use protective clothes made of a durable and flame-
resistant material (leather, thick cotton or wool), and feet
protection.
WELDING can produce fire or explosion
Welding inside empty places, such as tanks, drums or tubes,
may cause explosion. Sparkles can go all around the place
from the welding arc. The sparkles, hot working piece and
equipment, may cause fires and burns. An accidental contact
of the electrode with metal objects can cause sparkles,
overheating, explosion or fire. Check and make the area is
safe before starting any kind of weld.
• Remove all the inflammable material in a 15-meter (49.22ft)
area from the welding arc. If not possible, make sure it is
tightly covered with proper covers.
• Do not weld where welding sparkles may impact any kind
of inflammable material. Protect yourself and others from
the sparkles and hot metal.
• Be aware of that the welding sparkles and hot material may
go through small cracks or holes in adjacent areas.
• Make sure there is no flame around and always keep a fire
extinguisher near you.
• Be aware of that, while welding on the roof, floor, wall or
any kind of separation, heat may cause fire in non-seen
hidden parts.
• Do not weld on closed receptacles such as tanks, drums
or tubes, unless they have already been prepared for that
according to the AWS F4.1.
• Do not weld where there is inflammable dust, gas or liquid
vapor (as gasoline) present in the working atmosphere.
• Connect the working cable to the working area as close as
possible to the place where welding will take place. That
will prevent the welding current from going inside unknown
parts causing an electric shock, sparkles and risk of fire.
• Never use a welding unit in order to unfreeze frozen tubes.
• Remove the electrode from the electrode holder or cut the
welding wire near the contact tube when not in use.
• Use protective non-greasy clothes like leather gloves,
heavy shirt, loose and sealed trousers, high shoes or boots
and a hat.
• Take away from you all kind of combustibles, like butane
lighters or matchers, before welding.
• After finishing working, inspect the area and make sure
there are no sparkles, flames or embers.
• Only use appropriate breakers and fuses. Do not use a
bigger size or try to pass them through one side.
• Follow the OSHA 1910.252 (a) (2) (iv) and NFPA51B
regulations for hot working. Also, keep a fire extinguisher
near as well as a person able to take control of it.
METAL OR DIRT IN THE AIR can hurt your eyes
• Welding, wire-brushing, chipping or grinding could cause
sparkles and flying metal pieces. Whenever the welds are
cold, these can produce some dirt.
• Use approved safety glasses with side safeguards even
under your mask.
GAS CONCENTRATION can cause you illness or kill you
• Close the protective gas when not in use
• Always make sure there is an appropriate indoors
ventilation or an approved respirator that replaces
the air.
MAGNETIC FIELDS can affect implemented medical
equipment
• People who use
implemented medial units should stay away.
• People who use implemented medical units should ask
their doctor and the equipment manufacturer before getting
close to an arc welding, point welding, plasma cutting or
induction heating procedures.
NOISE can damage your ears
• Some procedures or equipment noises can damage your
ears. Use approved protection for your ears if the noise
level is very high or higher than 75dBa.
CYLINDERS may burst if they are damaged
Cylinders that contain protective gas, have it contained
under high pressure. If they are damaged, the cylinders may
explode. As they are usually a part of the welding
process, always treat them carefully.
• Protect the compressed air cylinders from the excessive
heat, mechanic shocks, physical hurt, dirt, flames, sparkles
and arcs.
• Install and secure the cylinders in a vertical position
securing them to a stationary support or a cylinder holder
in order to prevent them from falling or collapsing.
• Keep the cylinders away from the welding and electric
circuits.
• Never wrap the gas cylinder with the welding torch.
• Never allow a welding electrode to make contact with any
cylinder.
• Never weld a pressure cylinder: an explosion will occur.
• Only use the correct protective gas as well as regulators,
hoses and designed connections for the specific
application; keep them, like the rest of the components, in
a good condition.
• Always keep your face away from the output valve while
operating the cylinder valve.
• Keep the protective cover on its place on the valve except
when the cylinder is in use or connected to be used.
• Use the right equipment and procedures, and enough
people to lift and move the cylinders.
• Read and follow the instructions of the compressed air
cylinders, the associated equipment and the Compressed
Gas Air (CGA) P-1, along with the local regulations.
Danger of FIRE OR EXPLOSION
• Do not place the unit on, above or near combustible
surfaces.
• Do not install the unit near inflammable objects
• Do not overcharge your building wires – make sure your
power supply is appropriate in height and capacity, plus
protected in order to meet this unit necessities.
