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. /
  1. Interference with adjacent activities
  2. Hazardous energy exposure
  3. Electrical shock
  4. Arc flash
/
  1. Identify/verify circuits affected.
  2. Use circuit breaker LOTO device.
  3. Qualified personnel only. Shock resistant PPE and insulated tools.
  4. 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. /
  1. Trips, cuts, bruises, strains
  2. Falls
/
  1. Work area cleared of tripping and slipping hazards. Use of minimum PPE. Use gloves when handling metal boxes, receptacles, conduit and wire. Situational awareness.
  2. 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 /
  1. Coordinate outage with Leidos.
  2. Use circuit breaker LOTO device.
  3. Qualified personnel only. Shock resistant PPE and insulated tools.
  4. 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). /
  1. Trips, cuts, bruises, strains
  2. Electrical shock
/
  1. 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.
  2. Ensure circuit connections topanels are safe and compliant with NEC and related regulations. Ensure panel box and covers completely enclose any exposed circuits.
