Our Electrical and Controls Group includes Registered Electrical, Controls, and Instrumentation Engineers supported by our Fire/Explosion Investigators, Architects, and Materials experts.  These experts have designed, installed, tested, operated, and maintained electrical equipment, wiring, utility systems, controls and instrumentation, lighting, grounding systems and a variety of consumer, commercial, and automotive electrical products.
Our experts are especially experienced in safety and security design, warning, and interlocking procedures, since these are often the root causes of electrocutions, shocks, fires, explosions, and injury/deaths due to inadvertent equipment operation.  We rely extensively on applicable national and local standards – most notably the NFPA (National Fire Protection Association) and the NESC (National Electric Safety Code).
