ABSTRACT
Security (DHS) adopted an ‘‘all-hazards’’ approach, promoting the protection of chemical facilities from all hazards, independent of whether these are internal or external to the installation. Furthermore, methodological tools and standards are being developed for chemical facilities anti-terrorism (CFATS) aiming at ensuring protection from these threats. The U.S. DHS chemical facilities anti-terrorism standards (CFATS) program published on 9th April 2007 (Title 6 CFR Part 27) was designed to secure the U.S. chemical infrastructure by identifying high risk chemical facilities and requiring them to implement risk-based performance standards and other requirements. Depending on the quantities of dangerous substances present, the chemical facilities are screened and categorised into tiers. Top-tier facilities are then required to prepare and submit to DHS a Security Vulnerability Assessment (SVA) and prepare, submit, and implement a Site Security Plan (SSP) to address both the Vulnerability Assessment and applicable risk based performance standards (RBPS).
