4.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 weld- ing area.
4.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 circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
4.h. Also see item 7c.
CYLINDER may explode 
if damaged.
5.a. Use only compressed gas cylinders contain-
ing 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.
5.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
5.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.
5.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
5.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
5.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
5.g. Read and follow the instructions on compressed gas cylin- ders, associated equipment, and CGA publication
FOR ELECTRICALLY powered equipment.
6.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
6.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s rec- ommendations.
6.c. Ground the equipment in accordance with the U.S. National Electrical Code and the manufacturer’s recommendations.
FOR ENGINE powered equipment.
7.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
7.b. Operate engines in open,
7.c.Do not add the fuel near an open flame weld- ing arc or when the engine is running. Stop the engine and allow it to cool before refuel- ing to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated.
7.d. Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from
7.e. In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.
7.f. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.
7.g. To prevent accidentally starting gasoline engines while turn- ing the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.
7.h. To avoid scalding, do not remove the radia- tor pressure cap when the engine is hot.
ELECTRIC AND MAGNETIC FIELDS may be dangerous
8.a. Electric current flowing through any con- ductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines.
8.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.
8.c. Exposure to EMF fields in welding may have other health effects which are now not known.
8d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:
8.d.1. Route the electrode and work cables together - Secure them with tape when possible.
8.d.2. Never coil the electrode lead around your body.
8.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.
8.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.
8.d.5. Do not work next to welding power source.
