Chemical Reactivity Worksheet Transitioned to Center for Chemical Process Safety (CCPS)

MARCH 11, 2016--The Chemical Reactivity Worksheet (CRW) is a free software program that anyone can use to find out about the chemical reactivity of thousands of common hazardous chemicals, the compatibility of absorbents, and the suitability of materials of construction in chemical processes.

For more than 15 years, versions of the Chemical Reactivity Worksheet were developed through the collaboration of several organizations, including: OR&R, the Environmental Protection Agency, the Center for Chemical Process Safety (CCPS), the Materials Technology Institute, Dow Chemical Company, DuPont, Philips, and others.

The CRW has become an outstanding example of successful collaboration between government and private industry. The chemical industry understands the value of the program and plans to aggressively add new features to increase its utility for chemical facilities. While maintaining free and complete access to the information in the CRW, OR&R has transferred the development and distribution of the latest release, CRW version 4.0, to CCPS.

CRW 4.0 includes minor changes to the chemical compatibility table that predicts the hazards of mixing chemicals. It also includes a new module that addresses the compatibility of materials of construction with common chemicals. There are also several feature improvements, such as conversion of compatibility mixtures to Excel, migration of CRW3 data to CRW4, and data sharing alternatives. All future development and releases will be managed by CCPS. CRW version 4.0 can be downloaded at http://www.aiche.org/ccps/resources/downloadinstall .
