Caribbean Petroleum, Puerto Rico, 2009
A massive fire and explosion sent huge flames and smoke plumes into the air at the Caribbean Petroleum Corporation near San Juan, Puerto Rico. The resulting pressure wave damaged surrounding buildings and impacted moving vehicles. Preliminary cause found, was non working of the overfill protection system (part of the Safety Instrumented System).
Petrolia, Pennsylvania, USA, 2008
Thousands of residents of surrounding areas had to be evacuated to safer places when there was a release of large quantities of Oleum (fuming Sulfuric acid), from a chemical plant. The root cause was determined to be non implementation of a proper Safety Instrumented System.
Danvers, Massachusetts, USA, 2006
Massive explosion at an ink processing plant causes destruction of plant as well as surrounding homes, injuring many residents of surrounding areas. Cause? Lack of safety interlocks and automatic shutdown systems (in other words a Safety Instrumented System) in the plant.
Morgantown, North Carolina,USA, 2006
Explosion at a polymer manufacturing plant led to total damage of the facility, with a human fatality and several injuries. Investigations found out that a lack of process safety standards and non implementation of automatic interlock systems (in other words, Safety Instrumented Systems) as the root causes of the disaster.
Buncefield, UK, 2005
The Buncefield industrial disaster was one of the biggest disasters to strike the chemical and petrochemical industry in Europe in recent years. The blasts that occurred were so loud, they were heard as far away as France! (Buncefield is in the UK) The root cause was found out to be a probable malfunctioning Safety Instrumented System in one of the plants on the site.
The list goes on and on.....
Of course, you agree, that Safety Instrumented Systems are essential and are operational in many plants and facilities around the globe. But mere operation and existence of such a system, does not ensure, that it will always work as designed , is it not?
You need to know it in depth, to make it work for you.
To make it work for you, you need to know these systems thoroughly ( I mean not from a programming point of view but from a users point of view). You need to get trained in all the concepts and ideas of Safety Instrumented Systems. Note that here, when we refer to Safety Instrumented Systems(SIS), we also include Emergency Shutdown Systems (ESD), Safety Shutdown Systems, High Integrity Pressure Protection Systems (HIPPS) and all similar systems that are used to ensure the safe operation of plant and machinery, using instruments, electrical and pneumatic/hydraulic devices.
However, the jargon associated with these sophisticated process control systems is so put-offing and even confusing, that even experienced professionals cringe at the mention of Triple Modular Redundant, 2oo3 voting, SIL 3 or IEC 61508.
Does it really have to be this way?
No! Not really.
You can get this e-learning course on Safety Instrumented Systems(SIS) and learn all about these systems, in the comfort of your home or office.
