WHO SHOULD ATTEND
Your plant should have a minimum of two trained Incident Commanders per shift. The Incident Commanders come from a cross section of personnel generally ranging from members of management, engineering, maintenance, refrigeration, safety and production.
WHAT IS AN INCIDENT COMMANDER?
An Incident Commander is the person responsible for all aspects of an emergency response including developing incident objectives, managing all incident operations and applying resources as well as being responsible for all persons involved. The Incident Commander must immediately take charge of the event -- The decisions the Incident Commander makes in the first five to ten minutes will dictate the outcome of the event.
The decisions made by the Incident Commander have the potential to change the lives of the people in and around the facility. Therefore, proper and extensive training of not only the Incident Commander, but also the other employees is crucial.
