Commercial Fire Investigation
Commercial fires involve complex building systems and significant financial exposure. Our forensic engineers provide thorough origin and cause investigations.
Overview
Understanding Commercial Fire Investigations
From small retail spaces to large warehouse facilities, we apply systematic methodology to determine where the fire started, how it started, and why it spread. This provides the factual foundation for claims resolution and litigation.
Commercial buildings contain complex electrical systems, HVAC equipment, and diverse occupancies that create multiple potential fire sources. Our investigations combine fire science expertise with building systems knowledge.
Commercial fire losses often involve complex building systems, multiple occupancies, and significant financial exposure. Our investigators understand the unique fire dynamics of commercial structures and the regulatory landscape surrounding commercial fire safety.
What We Do
Electrical Systems
We evaluate panels, wiring, transformers, and connections to determine whether electrical failures contributed to ignition.
HVAC & Mechanical
We assess equipment condition, maintenance records, and installation quality to identify mechanical fire causes.
Storage & Hazardous Materials
We evaluate storage practices and material handling to determine their role in fire origin or spread.
Building Code Compliance
We review code compliance to identify deficiencies that may have contributed to the fire or its consequences.
Methodology
Our Process
Scene Examination
Conduct systematic scene examination working from areas of least damage toward the area of origin, documenting conditions throughout.
Building Systems Review
Evaluate fire protection systems, electrical distribution, HVAC, and commercial equipment to identify potential ignition sources and failure points.
Witness & Record Collection
Interview witnesses, review security footage, alarm records, and maintenance logs to establish the timeline of events.
Origin & Cause Determination
Apply NFPA 921 methodology to determine the fire's origin point and identify the ignition source, first fuel, and circumstances of ignition.

Common Questions
FAQ
How is a commercial fire investigation different from residential?
Commercial fires often involve more complex building systems, larger structures, and greater financial exposure. They may require evaluation of commercial-grade electrical systems, industrial equipment, and fire protection systems.
Do you investigate arson?
We determine whether a fire's cause is accidental, natural, or incendiary. If evidence suggests an intentional fire, we document our findings and coordinate with law enforcement as appropriate.
What is NFPA 921?
NFPA 921 is the Guide for Fire and Explosion Investigations, published by the National Fire Protection Association. It is the recognized standard of care for systematic fire investigation methodology, and our investigations adhere to its principles.
