Removal of bolted covers to expose bare, energized parts.Minimal PPE required: untreated natural fiber long sleeve shirt, untreated natural fiber long pants, safety glassesĬAUTION: Once opened, task and requirements may change. Opening hinged covers to expose bare, energized parts.(Safe Practice: When operating these devices, ALWAYS stand to the side NEVER stand directly in front of the device.) Minimal PPE required: untreated natural fiber long sleeve shirt, untreated natural fiber long pants, safety glasses. Operation of circuit breakers or fused switches (covers on or off).Tasks that can be performed at voltages <240V (assumes equipment is energized, and work is done within the flash protection boundary): These must be voltage rated greater than the working voltage. Insulated tools if working near exposed voltages.Voltage rated gloves if working near exposed voltages.Natural fiber outer wear (e.g., all cotton).Guidelines below are intended only for qualified and authorized persons.Ĭlothing/PPE requirements for the following tasks (Hazard Category 0): (Safe work practice - stand to the side of the device when operating.) NOTE: In case of an emergency, circuit breakers and/or disconnect switches can be turned off (de-energized) without the requirements of PPE. Refer to APS Policy on Energized Electrical Work, including Test & Measurement of Energized Circuits and to APS Energized Electrical Test & Measurement Authorization form. Extended Duration Permits for broad scope activities such as routine troubleshooting, testing of energized equipment <240 Volts can be put in place for an extended duration (up to one year).
#240 volt receptacle verification
Refer to Electrical Safe Work Practices.Įnergized Electrical (Hot) Work Permit: An approved and valid Hot Work Permit is required for all hot work other than voltage verification for LOTO. Training requirements: ES&H 114 (LOTO) / ES&H 375 (NFPA 70E) / ES&H 371 (electrical worker) - Observe Electrical Safe Work Practices. Refer to Qualified Electrical Worker Flow Chart. Only QUALIFIED PERSONNEL as authorized by the CAT/supervisor/division can perform such work. Engineered methods to prevent exposed sources of 50V and greater are to be implemented wherever practical. Refer to Electrical Safety Flowchart for Working On or Near Live Parts. Electrical hot work is defined as: Working on or near exposed conducting parts that are or might become energized at 50V or more.
