PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

WARNING

Mar ‘95

ELECTRIC AND

MAGNETIC FIELDS

may be dangerous

2.a. Electric current flowing through any conductor causes

localized Electric and Magnetic Fields (EMF). Welding

current creates EMF fields around welding cables and

welding machines

2.b. EMF fields may interfere with some pacemakers, and

welders having a pacemaker should consult their physician

before welding.

2.c. Exposure to EMF fields in welding may have other health

effects which are now not known.

2.d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

2.d.1.

Route the electrode and work cables together - Secure

them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode and

work cables. If the electrode cable is on your right

side, the work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as

possible to the area being welded.

2.d.5. Do not work next to welding power source.

1.h. To avoid scalding, do not remove the

radiator pressure cap when the engine is

hot.

regulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable for

the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely

chained to an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other

electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand

tight except when the cylinder is in use or connected for

use.

7.g. Read and follow the instructions on compressed gas

cylinders, associated equipment, and CGA publication P-l,

“Precautions for Safe Handling of Compressed Gases in

Cylinders,” available from the Compressed Gas Association

1235 Jefferson Davis Highway, Arlington, VA 22202.

Mar ‘95

WELDING SPARKS can

cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

Remember that welding sparks and hot

materials from welding can easily go through small cracks

and openings to adjacent areas. Avoid welding near

hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,

special precautions should be used to prevent hazardous

situations. Refer to “Safety in Welding and Cutting” (ANSI

Standard Z49.1) and the operating information for the

equipment being used.

6.c. When not welding, make certain no part of the electrode

circuit is touching the work or ground. Accidental contact

can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the

proper steps have been taken to insure that such procedures

will not cause flammable or toxic vapors from substances

inside. They can cause an explosion even

though

they have

been “cleaned”. For information, purchase “Recommended

Safe Practices for the

Preparation

for Welding and Cutting of

Containers and Piping That Have Held Hazardous

Substances”, AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or

welding. They may explode.

6.f.

Sparks and spatter are thrown from the welding arc. Wear oil

free protective garments such as leather gloves, heavy shirt,

cuffless trousers, high shoes and a cap over your hair. Wear

ear plugs when welding out of position or in confined places.

Always wear safety glasses with side shields when in a

welding area.

6.g. Connect the work cable to the work as close to the welding

area as practical. Work cables connected to the building

framework or other locations away from the welding area

increase the possibility of the welding current passing

through lifting chains, crane cables or other alternate cir-

cuits. This can create fire hazards or overheat lifting chains

or cables until they fail.

6.h. Also see item 1.c.
