Terrorism risk for US chemical facilities has driven enhanced security requirements. In this note, we talk to chemical security expert Patrick Coyle about physical security challenges and common implementations at these facilities.
The prevailing U.S. legislation on securing potentially hazardous chemicals, the Chemical Facility Anti-Terrorism Standard (CFATS) identifies a list of more than 300 chemicals that DHS wants to keep protected. Facilities housing these chemicals are required to report to the Department of Homeland Security who does a site assessment and determines if a facility is high or low risk. Facilities are placed into one of four tiers based on that assesment.
