Common questions

Frequently asked questions

Submit a case

What is a fire origin and cause investigation?

It's a methodical examination of a fire scene to determine where the fire started and what caused it. Our investigators document the scene, analyze burn patterns and evidence, and reach a defensible conclusion following NFPA 921.

Do you investigate fires to NFPA 921?

Yes. NFPA 921 is the recognized standard for fire and explosion investigations, and our findings are developed and documented to meet it, so they stand up under scrutiny.

Can you determine whether a fire was accidental or intentional?

Our investigators work to identify the origin and cause of the fire based on the physical evidence. Where the evidence supports it, that includes distinguishing accidental causes from incendiary ones.

Do you handle electrical fires and explosions?

Yes. We investigate electrical fires, industrial fires, and cylinder and tank explosions (propane and similar), alongside residential, commercial, and vehicle fires.

Do your fire investigators provide expert witness testimony?

Yes. Our investigators support claims and litigation with written reports, joint evaluations, evidence retention, and testimony at deposition and trial. See our litigation support services.

How soon should a fire investigator be involved?

As soon as possible after the fire is out. Early involvement preserves evidence and prevents spoliation, protecting both the investigation and your position.
