Jeffrey W. Barnes

Job Titles:
  • Registered Professional Engineer
Mr. Barnes is a registered professional engineer. Prior to joining 4x Forensic, he had worked at Underwriters Laboratory (UL) for 22 years. His work at UL consisted of product certification testing, analysis and standards writing for both electrical and gas appliances and other residential, commercial and industrial products. His work at UL related to analyzing products for fire, electrocution and pinching & laceration hazards. Examples of some of the types of products he was exposed to in his testing and certifications role included: cooking and refrigeration equipment, gas & electric heaters, motorized gate systems, factory automation equipment, power supplies, industrial control panels, panel boards, dead front switchboards, medium and low voltage switchgear, as well as the components used within these products such as motors, transformers, switches, relays, contactors, fuses & circuit breakers. His wealth of information in these various product design areas is of great use into the root cause failure forensic investigations of product design related fires and other forms of product failures. His experience involved in the authoring of UL standards has given him a vast range of standards knowledge which has enabled to him to be able to often quickly determine from visual examination whether products involved in fire or failure incidents are in accordance with the prevailing safety standards or good engineering design practice.
