The CSB investigated an explosion at the Technic, Inc., precious metal-processing chemical plant in Cranston, RI. The investigation found that Technic did not identify and evaluate the hazards associated with installing a vent collection system to handle the exhausts from multiple processes and those created by changes to facility processes and equipment. The investigation also found that a lack of process and equipment integrity procedures and training, as well as poor emergency planning by Technic and the local fire department, contributed to the incident. The CSB issued safety recommendations based on these root and contributing causes.
