WELDING

can

cause

fire

or

explosion.

Welding

on

closed

containers,

such

as

tanks,

drums,

or

pipes,

can

cause

them

to

blow

up.

Sparks

can

fly

off

from

the

welding

arc.

The

flying

sparks,

hot

workpiece,

and

hot

equipment

can

cause

fires

and

burns.

Accidental

contact

of

electrode

to

metal

objects

can

cause

sparks,

explosion,

overheating,

or

fire.

Check

and

be

sure

the

area

is

safe

before

doing

any

welding.

1.

Protect

yourself

and

others

from

flying

sparks

and

hot metal.

2.

Do

not

weld

where

flying

sparks

can

strike

flammable

material.

3.

Remove

all

flammables

within

ft

(10.7

of

the

welding

arc.

If

this

is

not

possible,

tightly

cover

them

with

approved

covers.

4.

Be

alert

that

welding

sparks

and

hot

materials

from

welding

can

easily

go

through

small

cracks

and

openings

to

adjacent

areas.

5.

Watch

for

fire,

and

keep

a

fire

extinguisher

nearby.

6.

Be

aware

that

welding

on

a

ceiling,

floor,

bulkhead,

or

partition

can

cause

fire

on

the

hidden

side.

7.

Do

not

weld

on

closed

containers

such

as

tanks,

drums,

or

pipes,

unless

they

are

properly

prepared

according

t0AWS

F4.1

(see

Safety

Standards).

8.

Connect

work

cable

to

the

work

as

close

to

the

area

as

practical

to

prevent

welding

current

from

traveling

long,
