- Do not weld in environments 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 steel 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 can be made of any
metal that contain these elements that can emanate toxic smoke
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 sure the area is safe before starting any kind of
weld.
- Remove all the inflammable material in a 11-meter (35.09ft)
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 materials 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 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 OSHA1710.252 (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 could 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 ventilation indoors or
an approved respirator that replaces the air.
MAGNETIC FIELDS may affect implemented medical
equipment.
- People who use cardiac pacemakers and other implemented
medical 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 ear.
- Use approved protection for your ears if the noise level is very
high or higher than 75 dBa
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 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 compressed air cylinders instructions,
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 to
achieve this unit necessities.
