Abstract This booklet, based mainly on the experience of factory inspectors, describes the following hazards: explosions due to physical and chemical reactions; fires due to contact of molten salt with combustible materials; burns; gassing from nitrous fumes. The precautions necessary to prevent injury due to the above hazards are described and include: strict care in the use of water near baths; use of dry sand or powder-type extinguishers; avoidance of entrapped air in hollow work being treated; supervision and care in storage and use of carbonaceous materials; removal of loose oxide scale from the bottom of the bath; avoidance of overheating and hot spots; consideration of the reaction between the molten nitrate, the steel bath and other metals; use of temperature controllers; systematic bath maintenance; protective clothing for workers.
