Cover Story: Understanding ISA – ISA
Transmission for commenting via ISA occurred on 2 April. Tomorrow IEC 2nd edition and future: If the PHA has established a tolerable risk for the events under review and determined the target risk reduction for the SIF, little additional engineering is required beyond normal instrument and control design. The International Society of Automation ISA, formerly Instrument Society of America recognized the need for an improved approach in handling process sector functional safety issues.
During the late s, more than sixty experts from diverse backgrounds including end users in the chemical petroleum industries, integrators, equipment manufacturers, consultants, osa safety regulators joined ISA84 to bring together their expertise in addressing process sector functional safety.
The need for improved understanding and harmonization of risk reduction approaches became evident with the occurrence of such major catastrophes as Seveso ItalyBhopal IndiaFlixborough U. ISA84 reviewed the IEC scope and purpose and recognized that it focused on equipment manufacturers’ requirements for developing products that could be utilized in safety applications.
These regulations helped define areas that must be addressed in order to achieve a mandated level of functional safety performance in industry. The standards development required isz integration of both quantitative and qualitative measures to ensure SIS designs had the ability to achieve their projected performance.
The impact of IEC on the safety life cycle is reflected in Figure 2. The process sector is faced with many plant isaa factors that require additional risk reduction analyses, such as security, wireless instrumentation, alarms, human factors, BPCS, and many other protection layer issues.
