Parikh has worked in various roles, including ISRO-ATIRA Research in Space & Textile Instrumentation, Instrumentation head at GACL, Chief Engineer at BCI in Saudi Arabia, and Assistant Professor in Instrumentation & Controls at LD College of Engineering. He is a former consultant to UPL Ltd. and is currently working with BEE as a sector expert in Chlor-Alkali. Additionally, Parikh is associated with the International Society of Automation (ISA).

The Organisers

The International Society of Automation (ISA)
ISA ( is a non-profit professional association that sets the standard for those who apply engineering and technology to improve the management, safety, and cybersecurity of modern automation and control systems used across industry verticals and critical infrastructure.

Founded in 1945, ISA has over 40,000 members worldwide, who are the who’s who of automation professionals in the industry. ISA develops standards, certifies industry professionals, provides education and training, publishes books and technical articles, and hosts conferences and exhibitions for automation professionals globally.

ISA Bangalore Section
ISA Bangalore Section ( brings to you various annual events in different industry verticals with a clear focus on Automation & Digitalization strategies. It brings together End Users, Automation Service Providers, Consultants, and Policy Makers on a single platform to help digitally transform and automate the industry.

Background - ISA /IEC 61511

Safety instrumented systems (SISs) are critical in process control to achieve safety and productivity. The primary aim of SIS is to take a process to a safe state when predetermined set points are exceeded. SISs are have been called emergency shutdown systems, safety shutdown systems, and safety interlock systems.

Several standards have been formalized to address the reliability of SISs. IEC 61508 and ISA / IEC 61511 are two well accepted standards being followed by leading product manufacturers and leading end users in small to large process industries encompassing Chemicals, Oil refining, Oil & Gas production, Non-nuclear Power generation etc.

All processes carry risk of small or big level to harm humans, environment or property. The safety engineering knowledge of above standards has a tremendous potential to reduce the risk of an identified safety instrumented function (SIF) by design of SIS to deliver the performance level of SIL1 / SIL 2 / SIL 3 in a systematic & most cost effective way to a tolerable level.

Government regulatory (OSHA/EPA), HSE-UK, & Seveso Directive –II in countries like the United States, UK, Europe considers these standards as “good engineering practices” for compliance to process safety management by law / act.

This seminar is designed to be an awareness program on SIS-SIF-SIL for an individual industry / institution operating where risk of an accident is a matter of time!
