Jackson, Arthur L. Electrical aspects of fire investigation. Fire Engineering. Vol 151 No 1 (January 1998). p 49-51.

Abstract: This article discusses some basic observations that they author has made regarding common electrical equipment. How a common duplex receptacle is mounted, how its wiring is attached and what are some common signs of failure are discussed. Similar comments are made regarding lighting fixtures, including fluorescent fixtures and their ballasts.

An examination should also include the rest of the electrical system to identify potential failure points in the wiring leading to appliances or receptacles.

The problems involving multi-plug power strips are discussed. This includes poor construction and stamped internal connections. Some fires have been caused by power strips in the vicinity of fish tanks that have become wet over time.

The key points the author identifies include the fact that electrical failure is not always a key indicator as to the cause of the fire; the investigation should include a full scene examination, witness interviews, reconstruction and consultations with experts; don't rush to a determination.
