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.

To Analyze Who Else Owns This Loss

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

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.

Evaluating Wind vs Water

Identifying the cause of damage is generally a critical component in the determination of insurance coverage.

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.

Injury Involving a Capstan Winch

Co-Authored with Jeff Warren, PE    A capstan winch uses a mechanically powered rotating cylinder, called a capstan, to apply pulling force through a rope. When the rope is looped around the rotating capstan and tightened, friction between the rope and capstan allows the winch to apply force to pull a load. A typical capstan […]
