The Above For Gasoline Engines

    1. To avoid scalding, do not remove the radiator pressure cap when the engine i hot.

ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS

    1. 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. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.
    3. Exposure to EMF fields in welding may have other health effects which are now not known.
    4. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:
      1. Route the electrode and work cables together - Secure them with tape when possible.
      2. Never coil the electrode lead around your body.
      3. Do not place your body between the electrode and workcables. If the electrode cable is on your right side, the work cable should also be on your right side.
      4. Connect the work cable to the workpiece as close as possible to the area being welded.
      5. Do not work next to welding power source.

shock hazardELECTRIC SHOCK CAN KILL.

    1. The electrode and work (or ground) circuits are electrically "hot" when the welder is on. Do not touch these "hot" parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
    2. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
      In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (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, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment:
      • Semiautomatic DC Constant Voltage (Wire) Welder.
      • DC Manual (Stick) Welder.
      • AC Welder with Reduced Voltage Control.
    3. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically "hot".
    4. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.
    5. Ground the work or metal to be welded to a good electrical (earth) ground.
    6. Maintain the electrode stinger, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.
    7. Never dip the electrode in water for cooling.
    8. Never simultaneously touch electrically "hot" parts of electrode stingers connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.
    9. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
    10. Also see Items 6.c. and 8.

warningARC RAYS CAN BURN.

    1. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Welding shield and filter lens should conform to ANSI Z87. I standards.
    2. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
    3. Protect other nearby personnel with suitable, nonflammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

warningFUMES AND GASES CAN BE DANGEROUS.

    1. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding hardfacing (see instructions on container or SDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and within applicable OSHA PEL and ACGIH TLV limits using local exhaust or mechanical ventilation unless exposure assessments indicate otherwise. In confined spaces or in some circumstances, outdoors, a respirator may also be required. Additional precautions are also required when welding on galvanized steel.
    2. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.
    3. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products.
    4. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.
    5. Read and understand the manufacturer's instructions for this equipment and the consumables to be used, including the Safety Data Sheet (SDS) and follow your employer's safety practices. SDS forms are available from your welding distributor or from the manufacturer.
    6. Also see item 1.b.

warningWELDING AND CUTTING SPARKS CAN CAUSE FIRE OR EXPLOSION.

    1. 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.
    2. 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.
    3. 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.
    4. 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).
    5. Vent hollow castings or containers before heating, cutting or welding. They may explode.
    6. 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.
    7. 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 circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
    8. Also see item 1.c.
    9. Read and follow NFPA 51B "Standard for Fire Prevention During Welding, Cutting and Other Hot Work", available from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
    10. Do not use a welding power source for pipe thawing.

warningCYLINDER MAY EXPLODE IF DAMAGED.

    1. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
    2. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
    3. Cylinders should be located:
      • way 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.
    4. Never allow the electrode, electrode stinger or any other electrically "hot" parts to touch a cylinder.
    5. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
    6. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
    7. 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
