Accident/Illness Investigation Procedure


An employee injured on the job is required to report the injury to his/her supervisor as soon as possible after the incident/accident.   The supervisor is responsible first, to assure that any injured employee is given immediate and proper medical care (as required) and that any potential hazard is mitigated and, second, to immediately (within 8 hours) contact the Environmental Safety & Health office (EH&S – x75179) to report the accident.   Environmental Safety & Health staff is available to assist the supervisor with the accident investigation. 

The purpose of accident investigation is to develop information on the actual and contributing causes of accidents in order to prevent recurrence.  No matter how conscientious the safety effort at the University, accidents are sometimes going to happen due to human or system error.   Our goal is to find and remove accident causes and to make the University a safer place to work.  Accident investigations help us meet that goal.

The following is a brief overview of the investigation and report form that is required for every employee accident. All blanks should be filled in.

This is where the supervisor verifies that the injury occurred while the employee was on the job and covered by Workers’ Compensation.  If the supervisor believes that the injury did not happen during the course of employment, an explanation is necessary.

The supervisor must sign and date the report.
