Applicability of PSM is sometimes a tricky subject. Once the site determines that a highly hazardous chemical (HHC) as defined in the standard is present and exceeds the threshold quantity, the site needs to develop and implement a PSM program covering the highly
hazardous chemicals, including interconnection with utilities that support the process. There are also exceptions to this rule, such as atmospheric tanks, storage of HHC, non-covered chemicals. However, there are many situations where these exceptions can lead to catastrophic results. For instance, one can remember the ammonium nitrate explosion that occurred in West, Texas back (2013), ITC Terminal fire in Deer Park, Texas (2019), and propylene explosion at Watson Grinding in Houston (2020).

The purpose of this workshop is to present what to look for when deciding if a site is PSM covered or not and how the extent of PSM boundaries should be defined.
