SAFETY
4
-
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.
§1.3 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.
