A former research engineer for DuPont at the Savannah River Laboratory, Jeff designed, patented and built an incinerator to burn radioactive waste. Later, Jeff was chief machine designer and owner of Warren Engineering Company, Inc., which designed and built special machinery for manufacturing automation. He combined his passion for keeping people safe with his knowledge of mechanical engineering, machine design, risk assessment and safety to pursue a career in forensic engineering.

He is a certified safety professional and has investigated more than 2000 claims involving machinery, equipment and products since 1987. He’s also testified in several hundred depositions and more than 85 trials in state and federal court. He has successfully passed Daubert challenges. Jeff was on the committee that authored ANSI B11.TR3-2000 entitled, “Risk Assessment and Risk Reduction – A Guide to Estimate, Evaluate and Reduce Risks Associated with Machine Tools.”

Jeff regularly investigates personal injury and wrongful death product liability claims as well as property damage claims involving machinery and equipment in both manufacturing and construction workplaces for both the plaintiff and the defense. Jeff can talk to a jury. He has a way of making complicated mechanical engineering, machine design, risk assessment and safety concepts understandable to the ordinary person. He is a court-qualified expert in mechanical engineering, machine design, risk assessment and safety.

To Analyze Who Else Owns This Loss

Noteworthy tips to consider when investigating any incident to determine responsible parties.

CASE STUDY: Can an Interlocked Guard take the Place of LockOut/TagOut?

Can an Interlocked Guard take the Place of LockOutTagOut Yes, if the Requirements of the Minor Servicing Exception are Met

Low Temperature Ignition of Wood

Co-Authored with Jerry Tindal, P.E. Wood fires can ignite well below the commonly recognized ignition temperature. Our latest white paper challenges court rulings regarding pyrolysis and explains how continued data collection will help investigators properly address future litigation.

Analysis of a Double Fatality Fire Allegedly Caused by a Portable Electric Heater

A portable electric heater was ultimately proven not to cause a tragic fire in which two children perished. The analysis performed shows the importance of conducting a thorough investigation and is a prime example of how utilizing the current scientific methodology is vital to getting to the bottom of a complex fire loss.

Settling Complex Claims with the Involvement Matrix

Use of an Involvement Matrix helps identify and clarify roles in complex multiple party claims

Don’t Let Your Child Be Injured

Some recliner chairs have a defective design that can cause death or serious injury to children due to an entrapment.

Investigation Saves Money on Tank Explosion Claim

Use of a “Responsibility Matrix” helps sort out a claim involving an explosion of a fuel oil tank being cut and welded on by a contractor

Documents You May Want to Ask for When Working a Machinery & Equipment Claim

Proper collection of documents is necessary to an efficient and organized process for working machinery and equipment claims.

Who Else Owns This Fire Loss?

A thorough analysis and asking proper questions assist in determining the other parties that may be partially or wholly responsible for a loss.

Wind & Water Investigation Tips

When it comes to wind and/or water damage claims, you can never have enough documentation. Here are a few tips to follow when recording and collecting specific data relative to the storm.
