Regulators will often require that a facility review their process safety management systems on a routine basis. These audits can be performed with internal or external resources. A PSM covered gas plant in the U.S. wanted to hire a consultant to perform an audit. Furthermore, the site wanted the results presented in such a way that they could understand and improve upon the shortfalls of their PSM systems. Based on conversations with other gas plants in the region, the site selected Smith & Burgess to perform the audit.
