Chlorine Institute Issues New Guidance on Estimating the Area Affected by a Chlorine Release

ARLINGTON, VA, United States, via ETELIGIS INC., 07/27/2015 – – As part of its ongoing efforts to encourage safety best practices and share the latest technical information, The Chlorine Institute (CI – www.chlorineinstitute.org) has issued a new version of Pamphlet 74 – Guidance On Estimating the Area Affected By A Chlorine Release. The new version, Edition 6 dated June, 2015, reflects CI’s strong collaboration with the U.S. Department of Homeland Security’s Chemical Security Analysis Center and incorporates information obtained from the DHS “Jack Rabbit I” chlorine release field tests.

The new guidance utilizes the Hazard Prediction and Assessment Capability (HPAC) model, developed and widely used by the U.S. Government, with the data and findings from the field trials to provide more accurate modeling results. This multi-scenario, science-based information will assist chlorine producers and users, local emergency planning committees, fire departments, and municipalities in estimating the area affected by a chlorine release for both emergency planning and hazard assessment.

“By using Jack Rabbit data, the sixth edition of Pamphlet 74 updates the chlorine dispersion modeling used to prepare for an actual incident,” said CI President Frank Reiner. “The members of CI are committed to the safe production, transport and use of chlorine, and we were very pleased to partner with DHS Science and Technology to present the test data in this easily-used format.”

The production, distribution and use of chlorine have strong safety records. However, in the rare event of a chlorine emergency, public and private sector emergency planners need accurate data about how chlorine will disperse in varied weather and terrain conditions. The Jack Rabbit I experimental releases performed at the U.S. Army Dugway Proving Ground in 2010 provide the most current information about the chemistry and physics associated with chlorine releases and allow planners to more effectively form emergency management and action plans keyed to local conditions and the unique properties of chlorine1.

Jack Rabbit II testing is scheduled to begin in August. In this test members of the Institute will be working side-by-side with DHS to obtain additional data and further refine chlorine dispersion models. Once the new data are analyzed, a seventh edition of Pamphlet 74 may be required, Mr. Reiner said.

All organizations that use or handle chlorine, along with emergency planners, should utilize the new edition of Pamphlet 74, available as a free download from the CI bookstore at: https://bookstore.chlorineinstitute.org/mm5/merchant.mvc?Session_ID=24a16b582943eabd2769b55d10c324d1&Store_Code=ci2store&Screen=PROD&Product_Code=EPR0074-HC&
