To assess risks associated with nanotechnology operations. The tool estimates an emission probability and severity band and provides advice on what engineering controls to use. It includes nine domains covering handling of liquids, powders and abrasion of solids. Combines hazard “severity” scores and exposure “probability” scores in a matrix to obtain a level of risk and associated controls out of 4 possible levels of increasing risk and associated controls. Control banding (CB) strategies (a qualitative risk characterization and management strategy) offer simplified solutions for controlling worker exposures to constituents that are found in the workplace in the absence of firm toxicological and exposure data.
