C) Fire and explosion prevention

Causes of fire and explosion are:

1) combustibles reached by the arc, flame, flying sparks, hot slag or heated

material;

2) misuse of compressed gases and cylinders;

3) short circuits.

BE AWARE THAT flying sparks or falling slag can pass through cracks, along pipes,

through windows or doors, and through wall or floor openings, out of sight of the

goggled operator. Sparks and slag can fly 10M.

To prevent fires and explosion: keep equipment clean and operable, free of oil,

grease, and (in electrical parts) of metallic particles that can cause short circuits.

If combustibles are in area, do NOT weld or cut. Move the work if practicable, to

an area free of combustibles.

Avoid paint spray rooms, dip tanks, storage areas, ventilators. If the work cannot

be moved, move combustibles at least 10M, away out of reach of sparks and

heat; or protect against ignition with suitable and snug fitting, fire- resistant covers

or shields.

Walls, ceilings, and floor near work should be protected by heat resistant covers

or shields. Fire watcher must be standing by with suitable fire extinguishing

equipment during and for some time after welding or cutting if:

a) appreciable combustibles (including building construction) are within 10m.

b) appreciable combustibles are further than 10m but can be ignited by sparks.

c) openings (concealed or visible) in floors or walls within 10m can expose

combustibles to sparks.

d) combustibles adjacent to walls, ceilings, roofs or metal partitions can be

ignited by radiant or conducted heat.

After work is done, check that area is free of sparks, glowing embers, and flames.

An empty container that held combustibles, or that can produce flammable or

toxic vapours when heated, must never be welded on or cut, unless container

has first been cleaned. This includes.......a thorough steam or caustic cleaning (or

a solvent or water washing, depending on the combustible’s solubility) followed

by purging and inerting with nitrogen or carbon dioxide, and using protective

equipment.

Water filling just below working level may substitute for inerting.

A container with unknown contents should be cleaned (see paragraph above),

do NOT depend on sense of smell or sight to determine if it is safe to weld or cut.

Hollow castings or containers must be vented before welding or cutting - they

can explode.

In explosive atmospheres, never weld or cut where the air may contain flammable

dust, gas, or liquid vapours.
