FUMES

AND

GASES

can

be

hazardous

to

your

health.

Welding

produces

fumes

and

gases.

Breathing

these

fumes

and

gases

can

be

hazardous

to

your

health.

Keep

your

head

out

of

the

fumes.

Do

not

breath

the

fumes.

If

inside,

ventilate

the

area

and/or

use

exhaust

at

the

arc

to

remove

welding

fumes

and

gases.

3.

If

ventilation

is

poor,

use

an

approved

air-supplied

respirator.

4.

Read

the

Material

(MSDSs)

and

the

instruction

for

metals,

cleaners.

5.

only

if

it

is

well

ventilated,

or

while

wearing

Shielding

gases

used

for

welding

can

displace

Be

sure

the

breathing

air

is

safe.

6.

Do

not

weld

in

locations

near

degreasing,

cleaning,

or

spraying

operations.

The

heat

and

rays

of

the

arc

can

react

with

vapors

to

form

highly

toxic

and

irritating

gases.

7.

Do

not

weld

on

coated

metals,

such

as

galvanized,

lead,

or

cadmium

plated

steel,

unless

the

coating

is

removed

from

the

is

well

and

if

necessary,

while

wearing

an

air-supplied

respirator.

The

coatings

and

any

metals

containing

these

elements

can

give

off

toxic

fumes

if

welded.

Chipping

and

grinding

cause

flying

metal.

As
