•
Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves,
heavy shirt, cuff less trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position
or in confined places. Always wear safety glasses with side shields when in a welding area.
•
Connect the work cable to the work as close to the welding area as practical. Work cables connected to the
building framework or other locations away from the welding area increase the possibility of the welding current
passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat
lifting chains or cables until they fail.
Rotating parts may be dangerous.
•
Use only compressed gas cylinders containing the correct shielding gas for the process used and properly
operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the
application and maintained in good condition.
•
Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
•
Cylinders should be located:
- Away from areas where they may be struck or subjected to physical damage.
- A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame.
•
Never allow the electrode, electrode holder or any other electrically "hot" parts to touch a cylinder.
•
Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
•
Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected
for use.
The knowledge of 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 all the world. Up to now, no material evidences show that EMF may have effects on
health. However, the research on damage 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.
