 pdf fileUnderstanding Safety Instrumented Systems And Safety Integrity Level SIL
Industrial safety in pre-digital eras centered mainly around safe work practices, hazardous materials control, and the protective “armoring” of personnel and equipment. Today, safety penetrates far deeper into more complex manufacturing infrastructures, extending its protective influence all the way to a company’s bottom line. Contemporary safety systems reduce risk with operational advancements that frequently improve productivity and profitability as well.

 pdf fileClass Division Hazardous Location
A major safety concern in industrial plants is the occurrence of fires and explosions. No other aspect of industrial safety receives more attention in the form of codes, standards, technical papers, and engineering design. Regulatory bodies like the Occupational Safety and Health Administration (OSHA) have established systems that classify locations which exhibit potentially dangerous conditi ons to the degree of hazard presented.

 pdf fileSIS Training Course
Basic Fundamentals Of Safety Instrumented Systems, The operation of many industrial processes, especially those in the chemical or oil & gas industries, involve inherent risk due to the presence of dangerous chemicals or gases. Safety Instrumented Systems (SIS) are specifically designed to protect personnel, equipment, and the environment by reducing the likelihood or the impact severity of an identified emergency event. Explosions and fires account for millions of dollars of losses in the chemical or oil & gas industries each year. Since a great potential for loss exists, it is common for industry to employ Safety Instrumented Systems (SIS) to provide safe isolation of flammable or potentially toxic material in the event of a fire or accidental release of fluids. This course will explain the basic concepts, definitions and commonly used terms in Safety Instrumented Systems and provide a basic understanding of SIS related concepts

 pdf fileManual Safety Integraty Level
This manual contains the manuscripts of various contributors, each one complete in itself. The first part presents an overview of the IEC/EN 61508. The second part is based on presentations that were given as part of a series of seminars by the author. It is therefore possible that some passages in the text are repeated.

 pdf fileHow to Determine the Safety Integrity Level (SIL) of a Safety System
IEC 61508 – a Generic Standard The IEC 61508 standard was published in 1998 and falls under a global approach of safety which could be compared with the ISO9001 system for quality or with the ISO14000 system for the environment. The standard is generic in that it applies to the safety systems irrespective of their application. It provides a generically-based standard that can be used directly by industry but can also help with developing sector standards (e.g. machinery, process chemical plants, medical or rail) or product standards (e.g. gas detection).
