8
least 10 metres away and out of the reach of sparks and heat or protect
against ignition with suitable and snug fitting, fire resistant covers or shields.
Walls touching combustibles on opposite sides should not be welded on, walls,
ceilings and the floor near the work area should be protected by heat resistant
covers or shields.
Openings (concealed or visible) in floors or walls within 10 metres may expose
combustibles to sparks.
Combustibles adjacent to walls, ceilings, roofs or metal partitions can be ignit-
ed by radiant or conducted heat.
After the work is done, check that the area is free of sparks, glowing embers and
flames.
An empty container that has held combustibles, or that can produce flamma-
ble or toxic vapours when heated, must never be welded, unless the container
has first been cleaned. Consult HSE INDG214, HSG250 and CS15. HSE docu-
ment CS15 includes information on cleaning by thorough steam or solvent/
caustic cleaning followed by purging and inserting with nitrogen, carbon diox-
ide or water filling just below working level.
A container with unknown contents should be treated as if it contained combus-
tibles (see previous paragraph), Do not depend on sense of smell or sight to
determine if it is safe to weld.
Hollow items must be vented before welding as they can explode.
Explosive atmosphere; Never weld when the air may contain flammable dust,
gas or liquid vapours (such as petrol).
SAFETY INSTRUCTIONS….cont
The welding arc produces ultraviolet (UV) and infrared (IR) rays as well as extreme tem-
peratures that can cause injury to your eyes and skin. Do not look at the welding arc
without proper eye protection.
The electric welding arc must not be observed with the naked eye. Always use a
welding mask; Ensure the welding mask is fitted with the correct shade of filter
lens for the welding current level, and covers the entire face from neck to the
top of the head.
Welding gauntlet gloves should be worn to protect the hands from burns, non-
synthetic overalls with buttons at the neck and wrist, or similar clothing should be
worn. Greasy overalls should not be worn. Wear suitable protective footwear.
Always wear correctly rated protective clothing which covers all areas of the
body; The operator should not weld with any bare skin showing to reduce the
chance of burns etc.
Avoid oily or greasy clothing, a spark may ignite them.
Hot metal such as electrode stubs and work-pieces should never be handled
