Activity: Electrical Demo and New Work in accordance with NFPA 70E (2015)HAZARDS
JOB STEP / HAZARDS / ACTIONS TO ELIMINATE OR MINIMIZE
EACH HAZARD
Identify circuits and turn off circuits feeding existing receptacles and fixtures. Verify zero voltage at receptacles and fixtures. /
- Interference with adjacent activities
- Hazardous energy exposure
- Electrical shock
- Arc flash
- Identify/verify circuits affected.
- Use circuit breaker LOTO device.
- Qualified personnel only. Shock resistant PPE and insulated tools.
- Assess risk with NCI-F Electrical Risk Assessment form, and establish approach and arc flash boundaries and arc flash PPE requirements in accordance with NFPA 70E (2015). Verify absence of voltage using IEC-6010-1 compliant volt meter.
Demo existing receptacles/fixtures circuits. Install conduit, boxes, raceways, etc. for new work. /
- Trips, cuts, bruises, strains
- Falls
- Work area cleared of tripping and slipping hazards. Use of minimum PPE. Use gloves when handling metal boxes, receptacles, conduit and wire. Situational awareness.
- Use safe ladder practices, including:Always inspect ladder before each shift. Ensure all four legs are stable before climbing ladder. Use three points of contact when ascending or descending. Work with a partner when removing large fixtures from ladders.
De-energize panel(s) by opening circuits at feeder panels, and verify zero voltage present at de-energized panels. / 1. Interference with adjacent activities
2.Hazardous energy exposure
3.Electrical shock
4.Arc flash /
- Coordinate outage with Leidos.
- Use circuit breaker LOTO device.
- Qualified personnel only. Shock resistant PPE and insulated tools.
- Assess risk with NCI-FElectrical Risk Assessment form, and establish approach and arc flash boundaries and arc flash PPE requirements in accordance with NFPA 70E (2015). Verify absence of voltage using IEC-6010-1 compliant volt meter.
Tie circuits into de-energized panel(s). /
- Trips, cuts, bruises, strains
- Electrical shock
- Clear work space of trip and slip hazards and use situational awareness. Use minimum PPE and special PPE when handling sharp, heavy, awkward objects. Work with a partner to assist in difficult tasks.
- Ensure circuit connections topanels are safe and compliant with NEC and related regulations. Ensure panel box and covers completely enclose any exposed circuits.
