CEP: Spotlight On Safety - Speaking Up for Safety: Hazard Awareness and Operational Discipline
CEP Magazine article, May 2013
On a cold February day in 1996, I was on a flight from Washington DC. Due to a horrific snowstorm, the flight landed 30 minutes late and passengers scrambled to make their connections. I turned to the pregnant passenger next to me to see if she needed assistance. The last thing I saw was her wide eyes... -
CEP: Process Safety Beacon- Pressure-Relief Valve Bonnets — To Plug or Not To Plug?
CEP Magazine article, May 2013
Understand what kind of pressure-relief valves you have in your plant, and know what you must do to ensure that they work properly. -
Improve Process Safety with Near-Miss Analysis
CEP Magazine article, May 2013
Valuable information about unsafe conditions resides in the large alarm databases of distributed control systems and emergency shutdown systems. This overlooked and underutilized information can be analyzed to identify process near-misses and determine the probability of serious accidents. -
CEP: Process Safety Beacon - Have You Heard a Pressure-Relief Valve Chatter?
CEP Magazine article, April 2013
Chattering is the rapid opening and closing of a pressure-relief valve. The resulting vibration may cause misalignment, valve seat damage, and, if prolonged, mechanical failure of valve internals and associated piping. Some causes of chattering include: excessive inlet pressure drop; excessive... -
Integrate Health, Safety, and Environment into Engineering Projects
CEP Magazine article, April 2013
Apply HSE principles during front-end engineering design to assure safe, operable, and economical facilities. -
CEP: Process Safety Beacon - Are Your Signs and Labels Confusing?
CEP Magazine article, March 2013
Lack of labeling can be a safety problem, and poor or confusing labels or information signs can be even worse. -
Assess Hazards with Process Flow Failure Modes Analysis
CEP Magazine article, March 2013
Process flow failure modes (PFFM) analysis is an intuitive, process-flow-directed way to identify potentially hazardous scenarios. Learn how to apply this technique to your process hazard reviews. -
CEP: Process Safety Beacon - What is Supporting Your Equipment?
CEP Magazine article, February 2013
Pipes and equipment that are not properly supported will be subject to stress, vibration, or other problems, This can cause leaks, or even a complete collapse of piping or equipment. But, problems with inadequate support of piping and other equipment are not always easy to see. -
CEP: Spotlight on Safety - The Importance of Considering the Highly Improbable (a.k.a. Black Swan Events)
CEP Magazine article, February 2013
Improbable does not mean impossible. As engineers, we tend to consider improbable things that have happened, and discard or minimize the improbable things that (to our knowledge) have not happened. Many times when the question "can this occur?" has been asked during a hazard analysis, the response... -
Beware of the Dangers of Cold Traps
CEP Magazine article, February 2013
Cold traps — steam traps that no longer drain condensate — are often ignored in lieu of less-critical leaking traps, until a catastrophic event, such as a plant shutdown or personal injury, occurs. Use historical data to accurately estimate the annual cost of these cold traps to justify their swift repair.
