Study Notes
Welding Safety Practices
- Proper equipment installation and maintenance, good operator practice, proper clothing and body protection, and equipment designed for the job and situation reduce electric shock hazards.
- Equipment should meet applicable NEMA or ANSI standards, such as ANSI/UL 551 for safety in arc welding machines.
- Care should be taken when connecting the grounding circuit to prevent welding current from flowing through unintended connections.
- Special radio-frequency grounding may be necessary for arc welding machines equipped with high-frequency arc initiating devices.
- Automatic machine controls that safely reduce open circuit voltage are recommended for significant welding and cutting under electrically hazardous conditions.
- Insulation and operating procedures must protect welders from higher open circuit voltages when special welding and cutting processes require it.
- Portable control devices must not be connected to circuits with operating voltages above 120 V, and exposed metal parts of these devices must be grounded.
- Employees must receive thorough electrical safety training before operating equipment, including training on points covered in ANSI Z49.1.
- Equipment, cables, fuses, plugs, and receptacles must be used within their current-carrying and duty cycle capacities to prevent overheating and rapid deterioration.
- Engine driven machines must be turned off before refueling, and installation must adhere to NFPA 70 and local codes for safety.
- Welding leads should be the flexible type of cable designed for welding service, and cable insulation must be kept in good condition.
- Key terms and definitions include ACGIH, ANSI, adiabatic recompression, ANSI Z49.1, and ANSI Z87.1, each relevant to welding safety practices.
