Overview

Determining Where and How a Fire Started

Our origin and cause investigations begin with a systematic examination of fire scenes to determine the area of origin and identify potential ignition sources. Every investigation follows NFPA 921 methodology — the nationally recognized standard for fire and explosion investigations.

We collect and survey physical evidence, conduct control testing, and perform detailed electrical component examination to establish the sequence of events leading to the fire. Our analysis includes arc mapping, conductor examination, and failure mode identification to build a complete picture of the fire’s origin and cause.

Each investigation produces thorough documentation suitable for litigation support, insurance claims, and regulatory proceedings.

Methodology

Investigation Process

01

Scene Examination & Survey

Systematic collection and survey of the fire scene. Document physical evidence, fire patterns, and structural damage to establish the area of origin.

02

Arc Mapping & Conductor Analysis

Detailed examination of electrical conductors and arc evidence throughout the fire scene. Map arc locations to trace the fire’s path and identify electrical involvement.

03

Electrical Component Evaluation

In-depth examination of electrical components, circuit breakers, panels, and wiring systems. Identify specific failure modes through control testing and laboratory analysis.

04

Documentation & Reporting

Comprehensive documentation of findings, including photographic evidence, diagrams, and detailed written reports. All conclusions supported by physical evidence per NFPA 921.

Standards

NFPA 921 Compliant

All origin and cause investigations are conducted in accordance with NFPA 921: Guide for Fire and Explosion Investigations. Our founder served on the NFPA 921 Technical Committee from 2004 through 2018, contributing directly to the development of the standard that governs fire investigation methodology nationwide.
