Control's Monthly Resource Guide. This Month, We Cover Process Safety

By Control Global Staff

This free tool from Rockwell Automation provides a guide to functional safety in the process industry. Introducing principles and standards relating to safety in process applications, the guide discusses how to implement effective solutions, and delivers an overview of functional safety guidance in the application of IEC 61511, the process industry-specific implementation of IEC 61508 that covers the safety management of electrical, electronic and programmable electronic systems throughout their lives. Process Safebook 1 provides insight to many facets of process safety, including safety lifecycle, hazards and hazard identification, risk and risk reduction, determining SIL targets, reliability techniques, SIL verification and functional safety, assessment and auditing.

Plant safety is at or very near the top of almost every manufacturer's operating priority list, often with a stated goal of zero incidents or accidents. Functional safety focuses on the safeguards required to manage and mitigate hazards. It seeks to answer the following types of questions: What can go wrong? How severe might it be? How likely is it to happen? Does it matter? Do we have enough protection? Safeguards typically include safety instrumented systems, such as emergency shutdown systems, alarm functionality of the distributed control system, burner management systems and pretty much any other automation and control technology that provides a layer of protection that enables safe operation. While functional safety has proven successful in reducing the probability of catastrophic events and does recognize the role of human factors, it does not explicitly address the key roles of management and business processes in maintaining the operational integrity and profitable performance of process plants. Process safety moves beyond functional safety, seeking to assure that the safeguards and safety equipment are available and operating at peak performance. It includes enforcing routine maintenance procedures, keeping maintenance backlogs or records of the safety critical devices that manage those risks and enforcing practices such as standard operating procedures. This white paper demonstrates how modern process safety management goes beyond functional safety to keep plants continuously safe and profitable. The free, downloadable PDF is found at

Over the past several decades, intrinsic safety has established itself as the preferred method of explosion protection for global energy and petrochemical projects. This latest installment in Control's "Essentials" series explains the ins and outs of intrinsic safety technology, how it compares with other methods of explosion protection, and new technology developments poised to increase the scope of its application to higher energy systems.

"Essentials of Safety Instrumented Systems" is another unit in Control's "Essentials" series. It provides process industry professionals with an up-to-date, top-level understanding of the most important SIS issues. From fundamental concepts and terminology to the ongoing debate over integrated versus stand-alone safety systems, readers can get up to speed quickly on the key technology and marketplace drivers.
