WELDING

can

cause

fire

or

Welding

on

closed

containers,

such

as

tanks,

drums,

or

pipes,

can

cause

them

to

blow

up.

Sparks

can

fly

off

fromt

the

arc.

The

flying

sparks,

hot

workpiece,

and

hot

equipment

can

cause

objects

can

cause

Check

and

is

safe

before

doing

any

welding.

1.

Protect

and

others

from

nearby.

6.

Be
