Response within the security plan context primarily refers to the response of appropriately trained personnel (either facility personnel or external first responders) to a threat or actual theft or release of Chemical of Interest (COI). This includes plans to mitigate or respond to the consequences of a security incident and to report security incidents internally and externally in a timely manner. An appropriate response should involve not only designated facility emergency response personnel but all facility personnel (including security personnel), as well as local law enforcement and other off-site emergency responders. Response security measures should address the identification of hazards and the proper response plans. Response plans should identify the numbers, capabilities, equipment, and training of the various response personnel. Properly equipped personnel, who understand the potential consequences of a security incident and the need for timely, effective actions, coupled with well- rehearsed response plans reduce the probability of an attack achieving the adversaries’ desired goals. Additionally, response personnel practiced in their response plans help ensure that onsite responders and local law enforcement, firefighting, ambulance, mutual aid, and rescue agencies are familiar with the facility and the chemicals stored onsite and that they are not impeded from reaching the location of the security event.
