June 21, 2004. Salem, New Hampshire: ioMosaic President Dr. Georges A. Melhem announced today that ioMosaic will release its comprehensive Web-based Reactivity Expert Program (WREP) later this year.

Incorporating the Reactivity Hazard Evaluation Package from ioMosaic's industry standard emergency relief system (ERS) design solution, SuperChems™, the first release of WREP will:

• Instantaneously generate the Binary Interaction Matrix for a mixture
• Utilize reactivity interactions of common Materials of Construction
• Provide Threshold Quantities (TQs) from OSHA, EPA, and TCPA lists of reactive chemicals
• Display toxicity values (ERPG and TLV) if available
• Rank reactivity hazards of pure chemicals and mixtures based on Melhem Index
• Tag chemicals as peroxide former, pyrophoric, water reactive based on functional groups
• Provide DSC database of more than 500 chemicals

“For many years now, the AIChE has demonstrated sustained leadership in safety and risk management through the Center for Chemical Process Safety” , said Dr. Melhem. “The Board's decision to induct the RMR as a member organization highlights the importance of understanding and managing chemical reactivity hazards and will no doubt encourage wider participation throughout the process industries.”

“Generating an interaction matrix is a highly time consuming task”, said Dr. Melhem. “WREP's powerful functionality is able to consolidate toxicity and reactivity information to generate an interaction matrix with a few mouse clicks, making it highly efficient to perform reactive hazard evaluations.”
