Response to a Threatening Call

July 1, 2014


The material in this post is extracted from Chapter 16 of the book Plant Design and Operations.

Process facilities are potential targets for malicious acts, ranging from simple vandalism all the way to major terrorist acts. Therefore all employees should know how to respond to suspicious activities and threats. (At the same time they should recognize that they are not law enforcement officers — it is important to inform professional security officials as soon as possible that there is a concern.) It is possible that an employee may receive a threatening call. The following Outside Call Checklist provides guidance as to the questions to ask and the actions to take.
