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. Door injuries are typically associated with an impact between the door or gate and a user. To reduce such injuries, standards have been developed to limit the speed and energy associated with a closing door or a gust of wind blowing a door open. Additional safety requirements exist for automatic doors, gates and door closers. Testing can determine whether a door meets applicable standards.
We have extensive experience in many aspects of door accidents including:
Through scientific analysis, we can help you answer pertinent questions such as:
Windblown Glass Door Shatter:
An improper closer on a store's glass front door permitted the wind to blow the door open rapidly. The subsequent impact with a nearby structural element shattered the plate glass and caused a long piercing cut on a customer's arm. Our analyses of the door closer and wind forces convinced the jury that the door closer was deficient and the customer was awarded a large cash settlement.
Elevator Door Closing:
A woman claimed to have been injured by a closing elevator door at her apartment complex. An inspection of the door determined that its closing speed and closing force complied with the applicable elevator standard requirements. Our biomechanical analysis showed that the forces imparted by the door during the alleged impact would not have been severe enough to cause the claimed injuries.

Forensic Engineering Experts: Codes & Standards
Codes and standards specify criteria necessary to ensure that a product, material or process will consistently and safely perform its intended function. Although standards provide minimum design requirements, conforming to a standard is not always sufficient in preventing an accident.

Welcome to the third and final post in our multipart series of blog posts about a young boy's fall and serious injury at a public playground. In our first post we gave a brief overview of the incident and our investigation. In the second post we discussed some of the safety standards applicable to public playgrounds. In this post, we will examine some of the impact-absorbing playground surfaces available to protect children at playgrounds from injury. If you would like to read the first two posts, they are available here and here.

Forensic Clues: All-Terrain Vehicles
Between 1982 and 1996, 2,795 people died riding all-terrain vehicles, ATV's. This was found in a study by the U.S. Consumer Product Safety Commission (CPSC). Over thirty percent of the riders killed were under the age of sixteen.
