Chemical Process Safety (PSM/RMP)

“Hot work” means work involving electric or gas welding, cutting, brazing, or similar flame or spark-producing operations.  Click “Read More” below to view and download the ppt.

Explosion at Belle Vue: 2 injured between life and death Tuesday, September 27, 2011, 17:11 An explosion occurred this morning at the Belle-Vue brewery Leeuw-Saint-Pierre. Two people were seriously injured. Their prognosis is engaged. The leak was stopped. An ammonia leak occurred around 8:50 Tuesday when three workers from an outside firm conducted the dismantling of an old installation. ” The

Have you every walked up on a hotwork job and asked who is the fire watch, only to have five welders not even look up and point to each other? It happens, but there is a simple way to correct this behavioral problem – High Visibility Vests.

Anyone involved with PSM/RMP knows about “facility siting” and all the attention it has gotten since the Texas City, TX incident in 2005.  Many companies struggle with this type of analysis, so I am passing along some great data that could be used during an expansion project at an existing facility or for a new

Over the past several years I have written many articles on the “safeguards” that get listed in Process Hazards Analysis.  In this article I want to focus our attention on the flaws that so many facilities are making in their PHAs.  Some facilities are really doing themselves an injustice by listing safeguards that have little

In many chemical processes around the world, operators are making their rounds checking on those items that have been deemed “critical to process safety”.  These rounds usually include checking pressure, temperature, tell-tale gauges, tank levels, heat tracing, taking samples, etc.  But in many instances involving these checklists, one item is painfully obvious after an incident–

Most businesses have established their safe upper and lower limits for the most obvious process parameters such as pressures, temperatures, and levels; but in a flammable liquid process involving non-conductive flammable liquids establishing a safe upper and lower limit for flow is an ABSOLUTE MUST.  There is not a Recognized and Generally Accepted Good Engineering

This regulatory requirement is often mismanaged, which oftentimes results in many other related issues within a process safety management system. In this article, I will discuss a methodology a facility can apply in establishing its “safe upper and lower limits.” In this example, I will use process pressure, as it is the easiest to illustrate,

Key provisions of PSM OSHA’s preamble to the PSM Standard goes a long way to provide us insight as to why there are 14 elements to the standard and what each requirement in each element is intended to serve.  The entire preamble is a very long read, but there are some key provisions in Section
