Kolene® molten salt processes generally offer many economic advantages compared to other processes. However, as with any chemical process, there are physical and health hazards that need to be addressed. These revolve around three primary areas: the elevated temperatures involved; the chemistry of the salts; and the fumes that may be developed by chemical reactions between the bath, the work and the atmosphere interface. With properly designed equipment and correct operational procedures, processing in molten salt can be as safe as any industrial process and safer than many. This Safety Manual does not replace the regular Safety/Maintenance Manual, but is intended only as a supplement to emphasize many safety related issues.
