SAFETY
Gas build up.
The build up of gas can causes a toxic environment, deplete the oxygen content in the
air resulting in death or injury. Many gases use in welding are invisible and odourless.
Shut off shielding gas supply when not in use.
Always ventilate confine spaces or use approved air-supplied respirator.
Electric and Magnetic Fields.
Electric current flowing through any conductor causes localized Electric and Magnetic
Fields (EMF). The discussion on the effect of EMF is ongoing in the entire world. Up
to now, no material evidences show that EMF may have effects on health. However, the
research on the effect of EMF is still ongoing. Before any conclusion, we should
minimize exposure to EMF as few as possible.
In order to minimize EMF, we should use the following procedures:
Route the electrode and work cables together – Secure them with tape when possible.
All cables should be put away and far from the operator.
Never coil the power cable around your body.
Make sure welding machine and power cable to be far away from the operator as far
as possible according to the actual circumstance.
Connect the work cable to the workpiece as close as possible to the area being welded.
The people with heart-pacemaker should be away from the welding area.
Noise can damage hearing.
Noise from some processes or equipment can damage hearing. You must protect your
ears from loud noise to prevent permanent loss of hearing.
To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs.
