prevent ignition of combustibles on the

other side by moving the combustibles

to a safe location. If relocation of

combustibles is not possible, designate

someone to serve as a re watch,

equipped with a re extinguisher, during

the cutting process and for at least one

half hour after the cutting is completed.

Do not weld or cut on materials having•

a combustible coating or combustible

internal structure, as in walls or ceilings,

without an approved method for

eliminating the hazard.

Do not dispose of hot slag in containers•

holding combustible materials. Keep a

re extinguisher nearby and know how

to use it.

After spot welding, make a thorough•

examination for evidence of re. Be

aware that easily-visible smoke or ame

may not be present for some time after

the re has started. Do not weld or cut

in atmospheres containing dangerously

reactive or ammable gases, vapors,

liquids, and dust. Provide adequate

ventilation in work areas to prevent

accumulation of ammable gases,

vapors, and dust. Do not apply heat to

a container that has held an unknown

substance or a combustible material

whose contents, when heated, can

produce ammable or explosive vapors.

Clean and purge containers before

applying heat. Vent closed containers,

including castings, before preheating,

welding, or cutting.
