INTRODUCTION

-

We

learn

by

experience.

Learning

safety

through

personal

experience,

like

a

child

touching

a

hot

stove

is

harmful,

wasteful,

and

un

wise.

Let

the

experience

of

others

teach

you.

Safe

practices

developed

from

experience

in

the

use

of

welding

and

cutting

are

described

in

this

manual.

Research,

development,

and

field

experience

have

evolved

reliable

equipment

and

safe

installation,

opera

tion,

and

servicing

practices.

Accidents

occur

when

equipment

is

improperly

used

or

maintained.

The

reason

for

the

safe

practices

may

not

always

be

given.

Some

are

based

on

common

sense,

others

may

require

technical

volumes

to

explain.

It

is

wiser

to

follow

the

rules.

Read

and

understand

these

safe

practices

before

at

tempting

to

install,

operate,

or

service

the

equipment.

Comply

with

these

procedures

as

applicable

to

the

par

ticular

equipment

used

and

their

instruction

manuals,

for

personal

safety

and

for

the

safety

of

others.

Fadure

to

Dbserve

these

safe

practices

may

cause

serious

injury

or

death.

When

safety

becomes

a

habit,

the

equipmont

can

be

used

with

confidence.

These

safe

practices

are

divided

into

two

Sections:

1

-

General

Precautions,

common

to

arc

welding

and

cutting;

and

2

-

Arc

Welding

(and

Cutting)

(only).

Reference

standards:

Published

Standards

on

safety

are

also

available

for

additional

and

more

complete

pro

cedures

thaii

those

given

in

this

manual.

They

are

listed

in

the

Stan~ards

Index

in

this

manual.

ANSI

Z49.1

is

the

most

complete.

The

National

Electrical

Code,

Occupational

Safety

and

Health

Administration,

local

industrial

codes,

and

local

inspection

raquirements

also

provide

a

basis

for

equip

ment

install

~tion,

use,

and

service.

1-2.

GENERAL

PRECAUTIONS

Different

arc

welding

processes,

electrode

alloys,

and

fluxes

can

produce

different

fumes,

gases,

and

radiation

levels.

In

addition

to

the

information

In

this

manual,

be

sure

to

consult

flux

and

elec

trode

manufacturers

for

specific

technical

data

and

precautionary

measures

concerning

their

material.

A.

Burn

Prevention

Wear

protective

clothing

-

gauntlet

gloves

designed

for

use

in

welding,

hat,

and

high

safety-toe

shoes.

Button

shirt

collar

and

pocket

flaps,

and

wear

cuffless

trousers

to

avoid

entry

of

sparks

and

slag.

Wear

helmei~

with

safety

goggles

or

glasses

with

side

shields

underneath,

appropriate

filter

lenses

or

plates

(protected

by

clear

cover

glass).

This

is

a

MUST

for

welding

or

cutting,

(and

chipping)

to

protect

the

eyes

from

radiant

energy

and

flying

metal.

Replace

cover

glass

when

broken,

pitted,

or

spattered.

See

1-3A.2.

Avoid

oily

or

greasy

clothing.

A

spark

may

ignite

them.

Hot

metal

such

as

electrode

stubs

and

workpieces

should

never

be

handled

without

gloves.

Medical

first

aid

and

eye

treatment.

First

aid

facilities

and

a

qualified

first

aid

person

should

be

available

for

each

shift

unless

medical

facilities

are

close

by

for

im

mediate

treatment

of

flash

burns

of

the

eyes

and

skin

burns.

Ear

plugs

should

be

worn

when

working

on

overhead

or

in

a

confined

space.

A

hard

hat

should

be

worn

when

others

work

overhead.

Flammable

hair

preparations

should

not

be used

by

per

sons

intending

to

weld

or

cut.

B.

Toxic

Fume

Prevention

Severe

discomfort,

illness

or

death

can

result

from

fumes,

vapors,

heat,

or

oxygen

enrichment

or

depletion

that

welding

(or

cutting)

may

produce.

Prevent

them

with

adequate

ventilation

as

described

in

ANSI Stan

dard

Z49.1

listed

1

in

Standards

index.

NEVER

ventilate

with

oxygen.

Lead

-,

cadmium

-,

zinc

-,

mercury

-,

and

beryllium

-

bearing

and

similar

materials,

when

welded

(or

cut)

may

produce

harmful

concentrations

of

toxic

fumes.

Ade

quate

local

exhaust

ventilation

must

be

used,

or

each

person

in

the

area

as

well

as

the

operator

must

wear

an

air-supplied

respirator.

For

beryllium,

both

must

be

us

ed.

Metals

coated

with

or

containing

materials

that

emit

toxic

fumes

should

not

be

heated

unless

coating

is

removed

from

the

work

surface,

the

area

is

well

ven

tilated,

or

the

operator

wears

an

air-supplied

respirator.

Work

in

a

confined

space

only

while

it

is

being

ven

tilated

and,

if

necessary,

while

wearing

an

air-supplied

respirator.

Gas

leaks

in

a

confined

space

should

be

avoided.

Leaked

gas

in

large

quantities

can

change

oxygen

con

centration

dangerously.

Do

not

bring

gas

cylinders

into

a

confined

space.

Leaving

confined

space,

shut

OFF

gas

supply

at

source

to

prevent

possible

accumulation

of

gases

in

the

space

if

downstream

valves

have

been

accidently

opened

or

left

open.

Check

to

be

sure

that

the

space

is

safe

before

re-entering

it.

Vapors

from

chlorinated

solvents

can

be

decomposed

by

the

highly

toxic

gas,

and

other

lung

and

eye

irritating

pro

ducts.

The

ultraviolet

(radiant)

energy

of

the

arc

can

also

decompose

trichloroethylene

and

per

chloroethylene

vapors

to

form

phosgene.

DO NOT

WELD

or

cut

where

solvent

vapors

can

be

drawn

into
