Critical Incident Stress Guide - US Occupational Safety & Health Administration: Workers responding to emergency events and or disasters will see and experience events that will strain their ability to function. These events, which include having to witness or experience tragedy, death, serious injuries and threatening situations are called "Critical Incidents." The physical and psychological well-being of those experiencing this stress, as well as their future ability to function through a prolonged response, will depend upon how they manage this stress.

Responding to Workplace Tragedies - Optum: Stories of natural disasters, crimes, accidents and other tragedies fill the daily news. While the media glare tends to focus on the human toll, businesses are often among the victims, left to grapple with the aftermath as they try to regain their foothold. Business leaders have to walk a fine line between helping employees deal with trauma and restoring their workplaces to normal as quickly as possible. Fortunately, employers don’t have to balance those burdens alone. Employee Assistance Programs (EAPs) offer critical incident response services that can provide guidance and support for both employees and managers following a critical incident. It’s important to understand how this resource works and when to call on it.
