Workplace Accident Investigations

Do you need an independent investigation conducted in reference to a workmen’s compensation claim?

Do you need a neutral, 3rd party investigator to help you analyze why a workplace accident occurred?

Has an employee filed a work comp claim due to an accident on the job and you need to pursue who else or what else may have been equally at fault?

Why initiate a workplace accident investigation?

Our workplace accident investigation services deploy the appropriate resources for every phase of the investigation, with experienced and qualified field investigators.

Complex accident investigations require a qualified specialist. The technical knowledge required to recreate a motor vehicle crash, for example, may rely on analysis of brake failure, roadway safety, and maintenance records.

We can help you determine:

What is an accident and should it be investigated?

Who should do the accident investigating?

What should be looked at as the cause of an accident?

  • Was the raw material substandard in some way?
  • Should personal protective equipment (PPE) have been used?

Workplace Accident & Job Site Investigations in St. Louis, Missouri

This model of a workplace accident investigation provides a guide for uncovering all possible causes and reduces the likelihood of looking at facts in isolation. Some investigators may prefer to place some of the sample questions in different categories; however, the categories are not important, as long as each pertinent question is asked. Obviously there is considerable overlap between categories; this reflects the situation in real life.

Again it should be emphasized that the above sample questions do not make up a complete checklist, but are examples only.

And finally, our workplace accident investigation final report will include:

Injured workers(s) and witness statements

Collection of Physical Evidence

Pursuing Background Information
