ChemHAT, the Chemical Hazard and Alternatives Toolbox, is an internet database developed by the US union IUE-CWA and the Blue Green Alliance. The organisations say: “Instead of what engineering controls and personal protective equipment do I need to lower the levels of exposure to a ‘safe’ level, ChemHAT is being designed to answer the question, ‘Is there a way to get this job done without using dangerous chemicals?’”
