Vehicle & Equipment Fire Investigation

Vehicle and Heavy Equipment Fire Investigation

JZ Engineering investigates fires involving vehicles and heavy equipment to determine origin, cause, ignition sources, fuel sources, and failure mechanisms.

Fire investigation services support attorneys, insurers, investigators, and Special Investigation Units in matters involving vehicle fires, heavy equipment fires, hydraulic system-related fires, electrical issues, fuel system concerns, recalls, and product defect claims.

Origin and Cause Analysis Grounded in Physical Evidence

Vehicle and equipment fire investigations require careful evaluation of the remaining evidence, including burn patterns, component condition, electrical systems, fuel systems, hydraulic systems, service history, recall information, and possible ignition sources.

JZ Engineering focuses on identifying what can be determined from the evidence, what potential causes can be evaluated, and whether the findings support a repair-related, product defect, maintenance, or subrogation claim.

Capabilities

Fire Investigation Capabilities

Depending on the matter, fire investigation may involve inspection of fire-damaged components, review of vehicle or equipment systems, analysis of recall information, and evaluation of possible ignition and fuel sources.

Fire Origin and Cause

Identifying Where a Fire Started and Why It Occurred

Fire origin and cause investigation begins with the physical evidence that remains after the fire.

JZ Engineering evaluates burn patterns, damaged components, possible ignition sources, fuel sources, vehicle or equipment systems, and relevant records to determine whether the evidence supports a specific origin and cause.

In some cases, the investigation may also evaluate whether a fire is consistent with a product defect, repair issue, maintenance concern, recall-related condition, or other failure mechanism.

Vehicle and Equipment Systems

Fuel, Electrical, and Hydraulic System Evaluation

Vehicle and heavy equipment fires often require evaluation of multiple systems and possible failure paths.

Investigation may include fuel system evaluation, electrical system evaluation, hydraulic system-related fire analysis, inspection of fire-damaged components, and review of service records, maintenance history, or prior repairs.

This type of analysis can help determine whether the fire was related to a component failure, system defect, repair issue, maintenance condition, or external factor.

Featured Example

Vehicle Fire Investigation Involving a Safety Recall

In one matter, a pickup truck fire involved a vehicle that was subject to a safety recall citing a risk of fire.

The investigation used the fundamentals of fire origin and cause analysis to test multiple hypotheses. The fire origin was found to be consistent with the recalled component, and close examination of the remaining evidence supported a cause consistent with the recalled product defect..

Product Defects and Recalls

Evaluating Recall-Related and Defect-Related Fire Claims

Some vehicle and equipment fire investigations involve questions about recalls, safety defects, product design, component failure, or manufacturing issues.

John Zeirke’s background in mechanical engineering and product design supports evaluation of design intent, failure modes, safety-related concerns, and whether the available fire evidence is consistent with a claimed defect or recall-related condition.

This can be especially important in matters involving product liability, insurance claims, and potential subrogation.

Investigation Questions

Common Issues in Vehicle and Equipment Fire Matters

Fire investigations often involve several overlapping technical and claim-related questions.

What Started the Fire?

Origin and cause analysis evaluates where the fire began, what ignition sources were present, and whether the evidence supports a specific cause.

Was a System Failure Involved?

Fuel, electrical, hydraulic, and mechanical systems may need to be evaluated to determine whether a component failure or system condition contributed to the fire.

Is There Subrogation Potential?

When a cause can be determined, the findings may help insurers and attorneys evaluate product defect, repair-related, maintenance-related, or subrogation claims.
