Safety Moment #15: Common Process Safety Hazards (Part 3)

Common Process Safety Hazards

One of the philosophies behind Process Safety Management (PSM) is that each chemical process is unique. Therefore it is not possible to have a prescriptive standard that tells operating companies what to do. Instead, companies have to identify the unique hazards associated with their facility, and then implement corrective actions based on a risk-ranking methodology. For this reason, facilities covered by PSM standards have to conduct a series of Process Hazards Analyses (PHAs), often using the Hazard and Operability (HAZOP) methodology.

Safety Moment #14: Trains, Cars and Root Cause Analysis

I live in a small town (population around 6,000) in central Virginia. The east coast railroad runs through it. Each day we see about 65 freight trains (CSX) and around 15 passenger trains (Amtrak). In recent months we have experienced a startling number of train/vehicle collisions. They are summarized here.

The most recent event (just last week) is shown in this YouTube video. The sequence of events was as follows:
