In this short guide, we will take a look at what we mean by ICS security assessment. ICS is short for industrial Control Systems. These may be DCS (Distributed Control Systems), or PLC (Programmable Logic Controllers) based, or some form of SCADA (Supervisory Control and Data Acquisition Systems) or any other programmable type systems. These include not only BPCS (Basic Process Control Systems) but also SIS (Safety Instrumented Systems). …
What is Intrinsic Safety? Intrinsic Safety is one of the several protection techniques used in hazardous areas. This type of protection is applicable to electrical apparatus in which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. This short Intrinsic Safety design guide will give you an idea of how Intrinsic Safety is used in hazardous areas. What are Hazardous Areas? Hazardous Areas …
In this short guide, we will take a look at the ANSI ISA S84 standard. What is ISA S84.01? This is the Functional Safety standard published by ISA (International Systems and Automation Society)’s S 84 committee. This is applicable to functional safety in the process industries. The standard was initially published as ANSI/ISA S84.01:1996 and was recognized by OSHA as a “generally accepted good engineering practice” via their letter …
In this small guide we will understand Safety Instrumented System requirements. But first we answer some basic questions such as, What is a Safety Instrumented System? The simplest explanation of a Safety Instrumented System (SIS for short) is ” a system comprised of active elements such as sensors, logic solvers and actuators, working together as a system, which acts to reduce the risk of an unwanted event in a …
In the next few minutes of reading this you will understand the difference between IEC 61511 and IEC 61508. What is IEC 61511? IEC 61511 is the process industry standard for Functional Safety and Safety Instrumented Systems. This standard has been developed by the International Electrotechnical Commission and is used globally. Process industries are those industries that handle bulk materials (rather than discrete parts) and include the Oil & …
The Abhisam free H2S awareness training has become a de-facto standard for anybody who needs to know about working in an area that may have Hydrogen Sulfide (also spelled as Hydrogen Sulphide in geographies such as the UK, India and Australia- both refer to the same H2S gas). This online H2S awareness course can be taken by anybody completely free of cost. Why is H2S awareness training so important? …
The Abhisam Intrinsic Safety course is now available for learners on the Abhisam Learning Portal. This training course on Intrinsically Safe systems, is the best online course for Instrumentation engineers, Automation professionals and Control System engineers who wish to design Intrinsically Safe systems in their plants and facilities that have hazardous areas. What are Hazardous Areas? As you probably know, hazardous areas (also known as classified locations) are those …
Update: July 2020:Functional Safety Training We have suspended all in person workshops, due to the pandemic. But all of these have now been replaced by easy, self paced e-learning Functional Safety courses, that you can take online. They are NOT videos of a professor speaking or a simple power point presentation. They are full fledged e-learning courses with text, animations, simulations, real life examples and calculations, exercises, videos and …
