Fire Losses Involving Improper Construction and Installation of Fireplaces and Chimneys

Author

On a cold winters night a family is gathered in the living room of their home enjoying the warmth of their fireplace.  After using the fireplace all day, they go off to bed to a nice restful sleep.  However, they are soon rudely waked by the sound of a smoke alarm in the home.  Rushing out into the cold night they can see smoke, but no flame in the home.  Outside, they can see that the chase around the fireplace chimney is burning.  The fire department is called and thankfully extinguishes the fire before it does widespread damage, however the family must leave the home for several months as repairs are made.

Hand and Finger Injuries from a Defective Snow Blower

Author

Nearly everyone who lives in a snowy climate would agree that a gas powered snow blower beats a person powered snow shovel for clearing the sidewalk or driveway.  Shoveling heavy, wet snow causes injuries from back problems to heart attacks.  No wonder that gas powered snow blowers of all sizes are a popular item this time of year.  The larger ones may be ride-on types; smaller ones are typically walk-behind.  In either case there is an auger to gather the snow as the device moves forward and a bladed fan (or “blower”) to discharge it out of a chute to one side or the other.  Read More

Using Historical Weather Data to Investigate Lightning Strike Claims

Author

Property damage claims to sensitive electronic equipment due to a direct or nearby lightning strike are frequently difficult to substantiate to a high degree of confidence.  Electrical damage to common consumer electronic equipment (televisions, computers and accessories, wireless routers, telephones, fax machines, electronic security systems, etc.) is most frequently not visible to the naked eye during a physical inspection of the allegedly failed equipment.  So, how do we investigate an electrical loss when an insured claims he has $30,000 worth of non-functioning equipment?

Installation can compromise PVC pipe

Author

PVC pipe is a durable material used in many construction and renovation applications. Despite its widespread use, problems can arise when manufacturer installation guidelines are not followed. This is especially true in applications that involve gluing joints or, using the more technical term, solvent welding. Read More

Electric Motors – The Electrical Work Horse of Industry

Author

Electric motors are the work horses of the electrical industry. Their use is so pervasive in our industrial society that approximately 75% of electrical power sold to industry is used for the operation of electric motors. With so many electric motors in operation, it becomes imperative that they be utilized and maintained properly. A failed electric motor causes delays in production, which in turn impacts the bottom line. Read More

Thermal Oil Equipment Fires

Author

Thermal oils, also called organic heat transfer fluids, are specialized industrial fluids that deliver energy from a central common fluid heater to different types of heat consuming equipment. Thermal oil systems are similar to hot water hydronic systems supplied by boilers; however, use of thermal oils allows systems to operate at higher temperatures without the higher pressurization required by water-based systems.

Explosion Investigations Uncover Answers

Author

The cause of an explosion can result from a chain of events in some cases. In many residential explosions and resulting fires, the facts can point to a number of potential causes. Certified fire and explosion investigators, like Warren engineers, have the experience and training to uncover and evaluate scenarios with high degrees of certainty. In some cases, like one residential explosion we investigated, the chain of events can start days before the loss.

A Fire Suppression System Failure?

Author

Yachts are equipped with fire protection systems to prevent extensive damage, protect lives and ensure safety. However, in order for these systems to be fully effective, they must be properly designed, installed, inspected and maintained.

Fire Investigation Points to Design Failure.

Author

Defects that cause problems in machines are categorized into two different concepts. Manufacturing defect is a term that applies to a situation where the defect was unintended. For example, a part was installed that did not meet the designer’s specifications or quality. A design defect is another matter. Design defect is a term that applies to a situation where the defect resulted from a purposeful decision or by failing to investigate or heed available design criteria on the part of a designer or builder.
