you wear flash goggles with side shields under the helmet, to give some
protection to the eyes should the helmet not be lowered over the face before
an arc is struck. Looking at an arc momentarily with unprotected eyes
(particularly a high intensity gas-shielded arc) can cause a retinal burn that
may leave a permanent dark area in the field of vision. Before welding whilst
wearing contact lenses, seek advice from your optician.
3) PROTECTION OF NEARBY PERSONNEL
For production welding, a separate room or enclosed bay is best. In open
areas, surround the operation with low reflective, non- combustible screens or
panels. Allow for free air circulation, particularly at floor level. Provide face
shields for all persons who will be looking directly at the weld. Others working in
the area should wear flash goggles. Before starting to weld, make sure that
screen or bay doors are closed.
2B) TOXIC FUME PREVENTION
Comply with precautions in 2-B. Generator engine exhaust must be vented to
the outside air. Carbon monoxide can kill.
2C) FIRE AND EXPLOSION PREVENTION
Comply with precautions in 2-C. Equipment’s rated capacity. Do not overload
arc welding equipment. It may overheat cables and cause a fire. Loose cable
connections may overheat or flash and cause a fire. Never strike an arc on a
cylinder or other pressure vessel. It creates a brittle area that can cause a
violent rupture or lead to such a rupture later under rough handling.
2D) SHOCK PREVENTION
Exposed live conductors or other bare metal in the welding circuit, or in
unearthed, electrically-LIVE equipment can fatally shock a person whose
body becomes a conductor. DO NOT STAND, SIT, LIE, LEAN ON, OR TOUCH a
wet surface when welding, without suitable protection.
2E) PROTECTION FOR WEARERS OF ELECTRONIC LIFE SUPPORT
DEVICES (PACEMAKERS)
Magnetic fields from high currents can affect pacemaker operation. Persons
wearing electronic life support equipment (pacemaker) should consult with
their doctor before going near arc welding, gouging, or spot welding
operations.
2F) TO PROTECT AGAINST SHOCK:
Keep body and clothing dry. Never work in damp area without adequate
insulation against electrical shock. Stay on a dry duckboard, or rubber mat
when dampness or sweat can not be avoided. Sweat, sea water, or moisture
between body and an electrically LIVE part - or earthed metal - reduces the
