This course addresses the critical skills essential to the effective investigation and evaluation of fires involving potential electrical fire causes. This course utilizes state-of-the-art techniques, practices, protocols and standards to assist investigators to properly and effectively evaluate electrical systems and associated components to ascertain their role in a fire. Students will be provided with a basic knowledge of electricity, electrical circuits and distribution systems, proper evaluation and recognition of common electrical faults and failures of electrical components and circuits, as well as a working knowledge of the National Electrical Code (NEC) and how it applies to fire investigations. The use of “Arc Mapping” will also be discussed and how it can be effectively used to assist in fire origin determination. Participants will also be able to demonstrate a general knowledge of electricity, electrical circuits, systems and arc mapping principles through a series of instructor-led “hands-on” practical exercises.

Topics to be covered:

  • Scene Safety; Definitions / Terms
  • Atomic Theory and Electricity
  • Ohm’s Law / Joules’ Law
  • Magnetism
  • AC vs. DC
  • Transformers
  • Three Phase Power
  • Branch Circuits
  • Service Entrance
  • Meter Usage
  • Circuit Breakers
  • Wiring
  • Measuring Voltage & Current
  • Electrical Failure
  • Evidence Collection
  • Scene Processing
  • Electrical Heating
  • Arcing Through Char & Melting
  • Examination Hints
  • Myth Avoidance
  • Arc Mapping
  • Open Neutral Failure
  • Intrusion Alarm and Surveillance Systems
  • Electrical Examinations
  • and Case Studies.

Hosts for this class must provide a training facility conducive to the size of the class expected, and audio-visual equipment that supports the class size and a PowerPoint presentation. Additionally, the Host will be required to coordinate closely with IAAI Training to receive/pick up Electrical Supplies paid for by IAAI.
