The chemical datasheets in the CRW database contain information about the intrinsic hazards of each chemical and whether it reacts with air, water, and/or other materials. Case histories of specific chemical incidents with references are also included.
NOAA has recently partnered with chemical industry experts to release a major update to the CRW (CRW version 3.0). This newest version of the program is the result of a two-year-long collaboration between NOAA chemical response specialists and expert chemists from the Dow Chemical Company.
All versions of the Chemical Reactivity Worksheet (CRW) were developed by NOAA’s Office of Response and Restoration, in collaboration with the Environmental Protection Agency and the Center for Chemical Process Safety.
