Guidance Document: Immediate Actions (IAs) for Transit Agencies for Potential and Actual Life-Threatening Incidents

The purpose of this Immediate Actions publication is to assist operators and other transit agency personnel who may encounter potential or actual life-threatening events involving criminal activities or terrorism. In such heightened risk situations, the transit employee may have only seconds to recognize, observe, and assess activities or incidents. Threats—including terrorists and violent criminal acts—can manifest themselves in a matter of seconds or minutes in a transit environment and can have serious impacts. Immediate Actions (IAs) are clear procedures that may help prevent or mitigate a terrorist or violent criminal act. The IAs in this document are focused on protecting a transit agency’s employees, passengers/patrons, and anyone else working in the vicinity. Section A provides general background information about the IA process and Section B describes the procedures and provides samples of immediate action instructions (called IA Matrix).
