The malicious acts against or within the chemical industrial sector pose a significant threat to both the employees working in the industry, to the communities around them, and to the nation they serve. This new book, the third in a series on critical infrastructure and homeland security, helps chemical manufacturers and processors prevent the devastating effects of such an attack by providing sound security principles and measures that they can implement in their chemical facilities. Addressing the security threats chemical production managers, chemical import managers, design engineers, and others must be prepared to meet on a daily basis, this book encourages a concerted effort to incorporate security upgrades in existing systems or to plan security in all new chemical processing sites. It addresses issues of monitoring, response, critical infrastructure redundancy, and recovery to minimize risk to the facility, the infrastructure, and the surrounding community.
