An end user of a product expects that a given product will not only function as intended, but will be safe from non-obvious hazards. Based upon decades of experience with mishaps during use of common and specialized equipment, thousands of standards have been developed for many consumer products and industrial equipment. Numerous organizations exist, e.g., ANSI, ASTM, SAE, and ASME, that regularly review and update these standards.
We have extensive experience with many types of products including:
Through scientific analysis, we can help you answer pertinent questions such as:
Lawn Tractor Fire:
A lawn tractor tipped over trapping its rider under it. While on its side, gasoline trickled from an air hole in the gas cap onto the surrounding area. Eventually, the spilled gasoline fumes ignited, severely burning the operator's legs. We demonstrated how the addition of a simple gasoline supply shut off valve for the air hole when the tractor is rolled on its side would have avoided the fire. Afterwards the manufacturer offered a $1 million settlement.
Alleged Elevator Door Defect:
A woman exiting an elevator claimed that the door closed too forcibly on her knee as she was exiting the car, seriously injuring her. Our testing revealed that the elevator door closed with reasonable speed, energy and force levels, and that her injuries could not have been caused by the closing of the subject elevator door.

Forensic Engineering Experts: Machine Guarding
The primary function of all guarding is to prevent an operator or bystander from being injured by a potentially dangerous portion of a machine. Often the hazard involves moving parts with the potential to cut, crush or draw-in body parts, although barrier guards may also be necessary when electrical, thermal or chemical dangers are present.

Forensic Engineering Experts: Doors & Gates
Doors and gates, whether automated or manual, can pose a serious hazard to users if not designed, manufactured, installed and maintained properly. The different types include automatic doors, overhead garage doors, elevator doors, sliding doors, swinging doors, and automatic gates.

Forensic Engineering Experts: Trucks
Heavy trucks, whether tractor-trailers, construction vehicles or garbage haulers, are involved in many serious traffic accidents due to their large weight, high centers of gravity, decreased visibility, poor handling and reduced braking efficiency. In addition, articulated tractor-trailers are subject to additional problems such as jack-knife and trailer sway instabilities.
