Safety instrumented systems angela summers

Ahmed Gamal

This document discusses safety instrumented systems (SIS), which are designed to respond to hazardous conditions in industrial plants. An SIS monitors for conditions that could become hazardous and responds by taking actions to prevent or mitigate hazards. Examples provided include a furnace that shuts off fuel valves in response to high pressure and a reactor that opens a coolant valve when temperature rises too high. The document outlines standards for good engineering practices in designing, implementing, and maintaining SIS according to lifecycle phases from planning and design to operations and auditing. Key aspects covered are managing risks to people and procedures, assessing and mitigating risk through assigning safety integrity levels, and proving that SIS designs achieve the desired safety functionality.

Mike Boudreaux

This document discusses effective storytelling techniques for presentations. It outlines the key elements of a compelling story, including getting the audience's attention, stimulating desire, and reinforcing the message with reasons. The document explores different story archetypes like the hero's journey and provides examples of how to construct stories around products or services. It also distinguishes stories from lectures and highlights aspects that make stories more engaging and persuasive.

Complying with New Functional Safety Standards

Design World

The document is a presentation on complying with new functional safety standards. It discusses what functional safety is, what is happening in the functional safety market, what standards should be used for machines, and how to determine safety levels and perform calculations according to standards like ISO 13849-1 and IEC 62061. It provides an example of applying the standards to a dual channel emergency stop application and calculating the resulting safety integrity level.

Part 4 of 6 - Analysis Phase - Safety Lifecycle Seminar - Emerson Exchange 2010

Mike Boudreaux

In San Antonio, Emerson Exchange 2010 featured a new Meet the Experts concept that provides participants to interact with recognized experts on focused topics. Emerson’s Mike Boudreaux provided a 2 hour session on Safety Lifecycle Management. This was an interactive short seminar that has been designed to help business leaders and managers in the process industries have a general understanding of existing industry standards and best practices for safety instrumented systems. This seminar provides a practical overview of the safety lifecycle, including key considerations for each phase. In addition to the typical design concepts related to safety instrumented functions and safety integrity levels, important concepts such as organizational design, competency management, planning, and continuous verification will be discussed. Part 4 describes the Analysis Phase and explains the managment considerations for hazard and risk assessment, layers of protection analysis, and safety requirements specification.

The document discusses safety instrumentation and safety integrity levels (SILs). It provides examples of major industrial accidents from 1974 to 2005 and their causes. These include failures of safety systems and instrumentation. The document then discusses key aspects of safety instrumented systems (SIS) such as their hardware components, separation from process controls, definition, and role in risk reduction. It introduces SIL ratings from 1 to 4 which define the reliability of a SIS based on its risk reduction factor and probability of failure on demand.

Part 6 of 6 - Operation Phase - Safety Lifecycle Seminar - Emerson Exchange 2010

Mike Boudreaux

The document discusses options for testing sensors and safety instrumented functions (SIFs) during operations, including testing sensors in place, removing sensors for off-site testing, or using smart features to test electronics and wiring. It provides an example of proof tests for a Rosemount 3051S pressure transmitter, including an analog output loop test covering over 50% of device failures, and a two-point calibration check covering over 95% of failures. Valve testing options and requirements for different safety integrity levels (SILs) are also mentioned.

Design for safety

Nurul Ikhmar Ibrahim

1. The document discusses product safety and design for safety. It defines key safety terms like hazard, risk, harm and discusses causes of unsafe products such as human errors and violations. 2. Safe product design can be achieved through intrinsic, ergonomic and usable safety approaches. Products should be evaluated based on their features, how users will interact with it, environmental factors and all stages of product life cycle. 3. Guidelines for safe design include avoiding designs that exceed users' capabilities and providing clear, intuitive user interfaces and controls. Examples show better and worse control room and appliance designs.

SIS “Final Element” Diagnostics Including The SOV, Using A Digital Valve Cont...

Emerson Exchange

This document discusses using a digital valve controller to improve diagnostics and testing of safety instrumented system (SIS) final control elements. Traditional testing methods are difficult and costly. A digital valve controller allows for partial stroke testing online which improves reliability while reducing costs. It also enables solenoid valve health monitoring and diagnostic capabilities. Field experience from Ras Gas in Qatar demonstrated benefits like reduced labor and improved predictive maintenance through signature-based testing and continuous monitoring.

Understanding Safety Level Integrity Levels (SIL)

Power Specialties, Inc.

Safety is an important consideration in process design. Safety integrity level (or SIL) is often used to describe process safety requirements. However, there are often misconceptions or misunder- standings surrounding SIL. While the general subject, functional safety and SIL, can be highly technical, the general ideas can be distilled down to a few readily understandable concepts. In this paper, we will discuss what SIL is, why it is important, what certification means, and the implications and benefits of that certification to the end user.

The ideal plant layout provides an optimal balance of output, space, and manufacturing processes to enhance production and safety.

ISO 26262 introduction

KoenLeekens

This document provides an overview of ISO 26262 and functional safety standards. It discusses key aspects of ISO 26262 including its structure, vocabulary, safety lifecycle, roles and responsibilities, and requirements for managing functional safety. ISO 26262 adapts IEC 61508 for automotive and aims to avoid faults and control failures through technical safety measures applied throughout the product lifecycle from concept to decommissioning. Management of functional safety is required to plan, coordinate, and track all safety activities.
