The Chemical Reactivity Worksheet (CRW) is a software program you can use to find out about the chemical reactivity of thousands of common hazardous chemicals.
For nearly 20 years, the CRW was developed jointly by NOAA's Office of Response and Restoration (OR&R) and the Environmental Protection Agency (EPA). Other organizations, such as the Center for Chemical Process Safety (CCPS), also began to collaborate on the development of the CRW in recent years.
With the release of CRW 4.0 in March 2016, the ongoing management and distribution of the CRW has been transitioned to CCPS. Additionally, NOAA and EPA will continue to publish their reactivity information in CAMEO Chemicals, a related website and desktop tool for emergency responders and planners.
