• other equipment in the environment. The user shall ensure that other
equipment being used in the environment is compatible. This may require
additional protection measures;
It may be possible to avoid the above by changing the time of day that
welding or other activities are to be carried out.
The size of the surrounding area to be considered will depend on the structure
of the building and other activities that are taking place. The surrounding area
may extend beyond the boundaries of the premises.
METHODS OF REDUCING EMISSIONS
MAINS SUPPLY
Welding equipment should be connected to the mains supply according to
the manufacturers recommendations. If interference occurs, it may be
necessary to take additional precautions such as filtering of the mains supply.
Consideration should be given to shielding the supply cable of permanently
installed welding equipment, in metallic conduit or equivalent. Shielding
should be electrically continuous throughout its length. The shielding should be
connected to the welding power source so that good electrical contact is
maintained between the conduit and the welding power source enclosure.
MAINTENANCE OF THE WELDING EQUIPMENT
The welding equipment should be routinely maintained according to the
manufacturers recommendations. All access and service doors and covers
should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except
for those changes and adjustments covered in the manufacturers instructions.
In particular, the spark gaps of arc striking and stabilizing devices should be
adjusted and maintained according to the manufacturers recommendations.
WELDING CABLES
The welding cables should be kept as short as possible and should be
positioned close together, running at or close to the floor level.
EQUIPOTENTIAL BONDING
Bonding of all metallic components in the welding installation and adjacent to
it should be considered. However, metallic components bonded to the work
piece will increase the risk that the operator could receive a shock by
touching these metallic components and the electrodes at the same time.
The operator should be insulated from all such bonded metallic components.
EARTHING OF THE WORKPIECE
Where the workpiece is not bonded to earth for electrical safety, nor
connected to earth because of its size and position, e.g. a ships hull or building
steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances.
