ACGIH

 

TVL

 

limits.

 

 

In

 

a

 

poorly

 

ventilated

 

area,

 

it

 

is

 

necessary

 

to

 

wear

 

an

 

approved

 

air-supplied

 

respirator.

  

 

Always

 

read

 

and

 

understand

 

the

 

Safety

 

Data

 

Sheets

 

(SDSs)

 

and

 

the

 

manufacturer

s

 

instructions

 

for

 

adhesives,

 

coatings,

 

cleaners,

coolants,

 

degreasers,

Always

 

have

 

a

 

trained

 

watchperson

 

nearby.

 

Welding

 

and

 

cutting

 

fumes

 

and

 

gases

 

can

 

displace

 

air

 

and

 

lower

 

the

 

oxygen

 

level

 

causing

 

injury

 

or

 

death.

 

Be

 

sure

 

the

 

breathing

 

air

 

is

 

safe.

  

 

Do

 

not

 

weld

 

or

 

cut

 

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.

 

 

Do

 

not

 

weld

 

or

 

cut

 

on

 

coated

 

metals,

 

such

 

as

 

galvanized,

 

lead,

 

or

 

cadmium

 

plated

 

steel,

 

unless

 

the

 

coating

 

is

 

removed

 

from

 

the

 

weld

 

area,

 

the

 

area

 

is

 

well

 

ventilated,

 

and

 

while

 

wearing

 

an

 

air-supplied

 

respirator.

 

The

 

coatings

 

and

 

any

 

metals

 

containing

 

these

 

elements

 

can

 

give

 

off

 

toxic

 

fumes

 

if

 

welded.

(ground)

 

circuit

 

are

 

electrically

 

HOT

 

whenever

 

the

Wear

 

dry,

 

hole-free

 

gloves.

 

Incorrectly

 

installed

 

or

 

improperly

 

grounded

 

equipment

 

is

 

a

 

hazard.

 

Insulate

 

yourself

 

from

 

work

 

and

 

ground

 

using

 

dry

 

insulating

 

mats

 

or

 

covers

 

big

 

enough

 

to

 

prevent

 

any

 

physical

 

contact

 

with

 

the

 

work

 

or

 

ground.

 

Additional

 

safety

 

precautions

 

are

 

required

 

when

 

any

 

of

 

the

 

following

 

electrically

 

hazardous

 

conditions

 

are

 

present:

 

in

 

damp

 

locations

 

or

 

while

 

wearing

 

wet

 

clothing;

 

on

 

metal

 

structures

 

such

 

as

 

floors,

 

gratings,

 

or

 

scaffolds;

 

when

 

in

 

cramped

 

positions

 

such

 

as

 

sitting,

 

kneeling,

 

or

 

lying;

 

or

 

when

 

there

 

is

 

a

 

high

 

risk

 

of

 

unavoidable

 

or

 

accidental

 

contact

 

with

 

the

 

workpiece

 

or

 

ground.

 

For

 

these

 

conditions,

 

use

 

the

 

following

 

equipment

 

in

 

order

 

presented:

 

1)

 

a

 

semi-

automatic

 

DC

 

constant

or

 

3)

 

an

 

AC
