A) BURN PROTECTION
The welding arc is intense and visibly bright. It’s radiation can damage eyes, penetrate
lightweight clothing, reflect from light coloured surfaces and burn the skin and eyes. Skin burns
resemble acute sunburn, those from gas - shielded arcs are more severe and painful.
DON’T GET BURNED! FOLLOW ALL SAFETY PRECAUTIONS!
Protective clothing
Wear long sleeved clothing (particularly for gas shielded arc) in addition to gloves, apron and
strong shoes. As necessary, use additional protective clothing such as leather jacket or sleeves,
flameproof apron, and fire-resistant leggings. Avoid outer garments of untreated cotton.
Bare
skin protection: Wear dark substantial clothing, Button collars closed to protect the chest and
neck and button any pockets to prevent entry of sparks.
Eye and head protection
Protect eyes from exposure to arc. NEVER look at an electric arc without protection. Welding
helmet or shield containing an appropriate filter plate
(Please refer to the section ‘Welding
Shield) . Place over face before striking arc. Protect filter plate with a clear cover plate. Cracked
or broken helmet or shield should NOT be worn; radiation can pass through to cause burns.
Cracked, broken, or loose filter plates must be replaced IMMEDIATELY.Replace clear cover plate
when broken, pitted, or spattered. WE SUGGEST 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 thatmay leave a permanent dark area in the
field of vision. Before welding whilst wearing contact lenses, seek advice from your optician.
Protection of nearby personnel
For production welding, a separate, well vented 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.
B) TOXIC FUME PREVENTION
Comply with all precautions in 1B.
C) FIRE AND EXPLOSION PREVENTION
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.
D) 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.
