Safety Precautions while Working
in Welding shop


(A)  Safety Precautions for Gas welding

1. One
should not use a leaking
gas cylinder.

2.  One should not handle oxygen
cylinders, valves, regulators, hoses or fittings with oily hands.

3. Welder should not mix the gases in one cylinder.

4. No one should transfer the gas from one cylinder
to another.

5. One should clearly mention on the
cylinders the type of gas in it (i.e. oxygen, acetylene, etc.).

6. One should use nose masks where the
local exhaust ventilation is not practicable.
Insist the safety
officer to provide
proper ventilation system.

7. Always avoid skin contact
with fluxes, which contain fluorides. If they will penetrate
the skin, they produce severe
irritation.

8. No one should weld the parts, which
are coated with toxic material such as lead, cadmium, zinc, mercury, or paint containing toxic before materials. Any such coatings
must be removed prior to welding.

9. Acetylene gas should not be brought in
contact with the unalloyed copper directly (except in torch) which may result in a violent explosion.


(B)  Safety Precautions for Arc welding

1. One should use protective clothing and
eye protection devices while performing arc welding
operation, otherwise radiation from electric arc will damage the retina of
eyes. One has to be sure that other people standing nearby also uses
eye-protection devices from ultraviolet rays.

2. Always use ear protection devices such
as muffler because excessive noise caused during the process of arc welding
may cause temporary
or permanent hearing
loss.

3. Welder should keep clothing and gloves dry.

4.  Always keep welding cables
free of grease
and oil.

5. One should prevent the non-insulated
portion of the electrode holder from touching the welding ground or job-piece when the current
is on.

6. Always keep
the body insulated from both the work and the metal electrode
holder.

7. One should carry out the welding process
by standing on the insulating material like
dry wood rather
than on a grounded metal structure.

8. It is easier and safer to establish an
arc on a clean surface than on a dirty or rusty one.

9. Always turn the welding
machine off when it is not in use.

10. One should not change the polarity
switch when the machine is under use. This will burn the surface of the switch and the resulting arc can cause injury to the welder.

11. Always avoid using electrode holders with defective
jaws or poor insulation.
