Sample Case Summaries

Electrical worker injured by arc blast.

An electrical utility received a trouble report that involved a smoking electric meter.  While troubleshooting, the utility company worker opened the metering compartment in the service entrance switchgear and was subjected to an electrical arc blast.  The questions raised included which codes applied and standards of care.

Grove worker killed while picking citrus.

A grove worker was electrocuted when his metal ladder contacted the hot conductor of an overhead electric power line.  The ladder the worker was using was made of conductive metal.  The length of the ladder was greater than the clearance to the overhead power lines.  The questions raised involved standards of care, OSHA, National Electrical Safety Code (NESC), and Electrical Safety in the Workplace (NFPA70E), and others.

Fire in lead acid battery manufacturing plant.

A fire destroyed a moth balled plant previously used to manufacture automobile batteries.  The fire was believed to be of electrical origin and destroyed not only the building but also the manufacturing equipment stored in the building and waiting shipment to other facilities.  Tasks included supporting a Fire Origin and Cause investigation but also determining the value of the damaged and destroyed manufacturing equipment.

Wild Lands Fire (Forest Fire) alleged to result from overhead electric utility lines.

A fire occurred which destroyed thousands of acres of woodlands, fields, farms, and homes with multiple fatalities.  Tasks included support of the Fire Origin and Cause investigation including analysis of the electrical system as well as determining alternate means and methods of constructing the overhead utility line where the fire originated.  Applicable codes included the National Electrical Safety Code (NESC). We have investigated and reported on the largest wildland fires in US history including those occurring in five states.

Railroad worker injured when contacting on overhead power line while riding on rail car.

A railroad worker was riding on top of a rail car in a terminal area.  While passing under an overhead power line, the worker made contact and was injured.  The questions raised involved standards of care, National Electrical Safety Code (NESC), railroad occupational safety and health standards and others.

Death of child in family swimming pool.

A child was killed when he touched the underwater light in the family swimming pool.  Investigation included recent upgrades to the electrical service entrance, upgrades to the pool equipment, installation of a whole house generator, repairs to lighting on the boat dock (over salt water) adjacent to the pool deck.  Extensive measurements were made of the ground resistance and electrical gradient in the pool water.  The pool lighting system was reconstructed in a temporary water tank to further test the equipment involved.
