摘要

A risk assessment carried out on a chemical process identified a flammable liquid release as a potential hazard. The flammable liquid, hexane, is used as a solvent in the process and is present in a dryer vessel during normal operations. The product from this vessel is a dry powder that is transferred to a packaging room directly below the vessel. Any leaks through the product discharge valve or inadvertent opening of the valve during the drying process or inadvertent opening/leak through of the hexane feed valves during the discharge process could lead to hexane release in the packaging room with potential for fire and explosion.
