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. A key aspect of accident investigation consists in determining the applicable standards and whether it was satisfied in the subject instance. Our extensive research capabilities ensure that you will be provided with the appropriate standard. We will also assess whether the standard was satisfied and if compliance with the standard served as adequate protection.
We have a large library of codes and standards and extensive experience in their interpretation and application including:
Through scientific analysis, we can help you answer pertinent questions such as:
Exterior Staircase Fall Down:
After exiting a building, an elderly woman descended an outdoor, wooden, wide set of stairs. While doing so, she lost her balance, fell, and was seriously injured. Upon inspection, we determined that the rise-height of the step where she fell was a half-inch higher than the previous steps. In addition, there was no handrail nearby. Both these items represented significant hazards and building code violations. The defendant settled the lawsuit after receiving our report.
Analysis of Current Ladder Safety Standard:
We have conducted tests and analyses to investigate the effectiveness of the ANSI ladder standards to address the dynamic flexibility of stepladders. Through physical testing and the use of finite element models of six and eight foot stepladders, we determined that the twist flexibility of most stepladders was far greater than necessary to safely accommodate uneven surfaces. We then showed that the increased flexibility contributed to the heightened potential for a three-leg contact instability.

Crash Data Retrieval - Modern Methods of Determining Crash Severity
Automobile collisions result in damage to property and injuries to people. Compensation is sought through insurance claims, law suits, and product liability claims. Knowing when injuries are more or less severe than is warranted by the damage level involved in the collision is important information. This can help people involved on both sides of litigation or settlements.

Forensic Engineering Experts: Airbags
Airbags are credited with reducing numerous injuries and saving many lives during vehicle accidents. However, there have been incidents where they do not function as intended, and have even caused injuries such as explosive powder burns, detached eye retinas, child suffocation and impact deaths.

Event Data Recorders and Collision Investigation
By: Al Duncan
Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.
