ELECTRICALLY POWERED EQUIPMENT
Faulty or improperly electrified equipment can cause
injury or death. Therefore:
EYE PROTECTION
Flying metal can injure eyes. Welding, chipping, wire
brushing and grinding can cause sparks and flying metal.
As welds cool, they can throw off slag. Therefore:
1.
Always have qualified personnel perform the installation, troubleshooting,
and maintenance work. Do not perform any electrical work unless you are
qualified to perform such work.
2.
Before performing any work inside a power source, disconnect the power
source from the incoming electrical power using the disconnect switch at the
fuse box before working on the equipment.
3.
Install equipment in accordance with the U.S. National Electrical Code, all
local codes and the manufacture’s recommendations.
4.
Ground the equipment in accordance with the U.S. National Electrical Code
and the manufacturer’s recommendations.
1.
Wear approved safety glasses with side shields even under your welding
helmet.
2.
Warn others nearby about flying metal hazard.
EQUIPMENT MAINTENANCE
Faulty or improperly maintained equipment can cause
injury or death. Therefore:
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently
release gas. Sudden rupture of cylinder, valve, or relief
device can injure or kill. Therefore:
1.
Always have qualified personnel perform the installation, troubleshooting,
and maintenance work. Do not perform any electrical work unless you are
qualified to perform such work.
2.
Before performing any maintenance work inside a power source, disconnect
the power source from the incoming electrical power.
3.
Maintain cables, grounding wire, connections, power cord, and power supply
in safe working order. Do not operate any equipment in faulty condition.
4.
Do not abuse any equipment or accessories. Keep equipment away from:
heat sources such as furnaces
wet conditions such as water puddles and inclement weather
oil or grease
corrosive atmospheres
5.
Keep all safety devices and cabinet covers in position and in good repair.
6.
Use equipment only for its intended purpose. Do not modify it in any
manner.
1.
Use the proper gas for the process and use the proper pressure reducing
regulator designed to operate from the compressed gas cylinder. Do not use
adaptors. Maintain hoses and fittings in good condition.
2.
Always secure cylinders in an upright position by chain or strap to suitable
hand trucks, undercarriages, benches, walls, post, or racks. Never secure
cylinders to work tables or fixtures where they may become part of an
electrical circuit.
3.
When not in use, keep cylinder valves closed. Have valve protection cap in
place if regulator is not connected. Secure and move cylinders by using
suitable hand trucks. Avoid rough handling of cylinders.
4.
Locate cylinders away from heat, sparks, and flames. Never strike an arc on
a cylinder.
5.
For additional information, refer to CGA Standard P-
1, “Precautions for Safe
Handling of Compressed Gases in Cylinders”, which is available from
Compressed Gas Association, 1235 Jefferson Davis Highway, Arlington, VA
22202.
ADDITIONAL SAFETY INFORMATION
For more information on safe practices for electric arc
welding, refer to the following publications.
HEARING PROTECTION
Prolonged Noise from Capacitor Discharge welding
applications can damage hearing if levels exceed limits
specified by OSHA. Therefore:
1.
ANSI/ASC Z49.1 Safety in Welding and Cutting
2.
AWS C5.1 Recommended Practices for Plasma Arc Welding
3.
AWS C5.6 Recommended Practices for Gas Metal Arc Welding
4.
AWS SP Safe Practices (Reprint) Welding Handbook
5.
ANSI/AWS F4.1 Recommended Safe Practices for Welding and Cutting of
Containers That Have Held
Hazardous Substances.
1.
Use Approved ear plugs or ear muffs if noise level is high.
2.
Warn others nearby about noise hazard.
3.
For additional information, refer to OSHA Safety Standards 3074.
MOVING PARTS CAN CAUSE INJURY
Electric fan can start at any time without warning and
cause severe injury, therefore:
1.
Always disconnect electrical power prior to service to prevent the fan from
starting unexpectedly.
2.
Keep all doors, panels, covers, and guards closed and securely in place.
3.
Have only qualified people remove guards or covers for maintenance and
troubleshooting as necessary.
4.
Keep hands, hair, loose clothing, and tools away from moving parts.
5.
Reinstall panels or guards and close doors when servicing is finished and
before reenergizing welder.
