Department of Homeland Security - Chemicals of Interest

On April 2, 2007 the Department of Homeland Security (DHS) finalized interim chemical security regulations. Section 550 of the Department of Homeland Security Appropriations Act of 2007 required DHS to develop a temporary program for instituting security performance anti-terrorism standards for high-risk chemical facilities.

The new regulations include a list of DHS Chemicals of Interest (http://www.ombwatch.org/info/IP_ChemicalFacilitySecurity.pdf) which contains over 340 chemicals. DHS will now require owners of chemical facilities housing certain quantities of any of these substances to complete a preliminary screening assessment that determines the level of risk associated with the facility. If a chemical facility preliminarily qualifies as high risk, its owners will be required to prepare and submit a security vulnerability assessment and site security plan. Submissions will be verified through audits and site inspections. The department will provide technical assistance to facility owners and operators as needed. Security standards will be required to achieve specific outcomes, such as securing the perimeter and critical targets, controlling access, deterring theft of potentially dangerous chemicals, and preventing internal sabotage.

The List of DHS Chemicals of Interest covered in the new regulations can now be found here in the HazMat Zone Web site's HazMat List Section.

A chemical is not listed in TRI unless it is involved in a significant toxic release incident or waste management event. That's exactly why this list of TRI chemicals linked to their MSDSs serves as a valuable and convenient reference tool for anyone with job responsibilities that include avoiding, investigating, reporting, or responding to these types of incidents and events.

The chemicals are listed in order of their CAS Number. The materials on the list underlined in black are linked to the Genium Hazard Overview and MSDS at the HazMat Zone. If you're a HazMat Zone Subscriber, you'll be able to link to the Genium MSDS for each of these materials.
