♦ During pauses between welding runs, electrode holders should be so placed that they cannot make
electrical contact with persons or conductive objects.
♦ The welding leads, both the electrode lead and the work lead, must be protected from damage.
Damaged leads must not be used.
♦ Keep combustible materials away from the welding area. Have a suitable fire extinguisher handy.
♦ Do not stand on damp ground when welding.
4.2 Personal Protection
The radiation from an electric arc during the welding process can seriously harm eyes and skin. It is
essential that the following precautions be taken:
♦ Gloves should be flameproof gauntlet type to protect hands and wrists from heat burns and
harmful radiations. They should be kept dry and in good repair.
♦ Protective clothing must protect the operator from burns, spatter and harmful radiation. Woollen
clothing is preferable to cotton because of its greater flame resistance. Clothing should be free
from oil or grease. Wear leggings and spats to protect the lower portion of the legs and to
prevent slag and molten metal from falling into boots or shoes.
♦ Face Shield
It is recommended to use a welding face shield, conforming to the relevant standards, when
electric arc welding. Use a welding face shield in serviceable condition and fitted with an eye filter
lens to safely reduce harmful radiation from the arc as per Table 1.

Table 1 - Filter lens size verses welding current
Protective filter lenses are provided to reduce the intensity of radiation entering the eye thus
filtering out harmful infra-red, ultra-violet radiation and a percentage of the visible light. Such
filter lenses are incorporated within face shields. To prevent damage to the filter lenses from
molten or hard particles an additional hard clear glass or special clear external cover lens is
provided. This cover lens should always be kept in place and replaced before the damage impairs
your vision while welding.
5. Resuscitation For Electric Shock Victims
Electric shock may kill immediately. Early resuscitation is required if a life is to be saved. Every Second
Counts! Electrical currents may:
♦ Stop the heart;
♦ Cause contraction of the muscles of the body;
♦ Paralyse breathing due to paralysis of the centre of respiration in the brain;
♦ Cause burns.
The victims often cannot free themselves from the current and may not be able to breathe due to fixation of
the chest.
