ADDING VALUE Process industry clients need to cost-effectively implement the requirements of the safety and security standards. exida enables this this by creating unparalleled engineering tools that reduce the time and cost of compliance, delivering coaching and training to rapidly develop a knowledge base within the clients organization, offering a full range of lifecycle services to supplement in-house resources, and providing independent assessments to ensure compliance and traceability. Whatever your needs, exida has you covered. Let our knowledge be your guide. TOOLS FUNCTIONAL SAFETY FUNCTIONAL SAFETY & CYBERSECURITY ASSESSMENT CYBERSECURITY PSM ALARM MANAGEMENT

3 POINT A: PSM Process Hazards Analysis Employee Participation Process Safety Information Operating Procedures Contractors Training Prestartup Safety Review Hot Work Permits Management of Change PROTECTION OF EMPLOYEES Mechanical Integrity Incident Investigation Emergency Planning and Response Compliance Audits Trade Secrets Documentation Control / Access Management Commitment Process Safety Management (PSM) is an integral part of the plant s overall management system. PSM is essential in order to properly identify and understand potential process hazards so as to prevent process-related incidents and injuries. A systematic approach to evaluating the whole process is imperative when implementing an effective PSM program. This helps ensure employee and public safety, improve business value and performance, as well as compliance with government regulations. exida works with its clients to help develop an efficient PSM program for their organization, which includes an evaluation of current processes to define key elements that may impact such processes. This integrated lifecycle approach leverages activities from multiple disciplines into a coordinated, streamlined process. Having a sound Mechanical Integrity program for the Safety Instrumented System (SIS) is just one of the key components to ensuring that there is an appropriate set of Operating and Maintenance policies & procedures in place to ensure the integrity of the plant. By having the correct procedures and test plans in place, your critical systems can enjoy years of trouble free service. PSM

4 FUNCTIONAL SAFETY To improve plant process safety, functional safety systems enable the orderly shutdown of processing units when abnormal situations occur that are beyond the capabilities of the regulatory control system or operators to correct or to prevent a catastrophe. exida makes implementation of safety and high availability automation products easier and more cost effective than ever. Users now have the ability to use procedures and tools that were written by industry authorities for a fraction of the cost of having them internally developed, and without having to go through the effort of having core staff trained to become safety and reliability experts. This lets you and your staff focus on your core tasks. The lifecycle is a series of phases from initiation and specifications of safety requirements, covering design and development of safety features in a safety-critical system, and ending in decommissioning of that system. exida provides initial guidance on performing key facets of the lifecycle, providing specific services for individual tasks within each lifecycle phase. FUNCTIONAL SAFETY ALARM MANAGEMENT Having effective operators in a process plant is critical to maximizing production efficiency, product quality, plant reliability, and safety. During a single shift, operators make numerous decisions that affect plant profitability and safety. These include actions to avoid unplanned upsets or to mitigate events that could lead to plant outages or loss of containment incidents. A well-designed and highly functional alarm system can add to the operator s decision-making ability.

5 An effective alarm management program can deliver quantifiable business benefits in the following areas: Improved plant reliability and safety (Less lost production, fewer demand on the SIS) Increased operator productivity Reduction in maintenance of process equipment Production optimization / debottlenecking / increased throughput Proven in use validation of alarm credit in Layer of Protection Analysis (LOPA) Reduced environmental / regulatory incidents Energy savings CYBERSECURITY CYBERSECURITY Cybersecurity has rapidly become something that goes hand-in-hand with process safety. It is part of the Chemical Facility Anti-Terrorism Standards (CFATS) as well as the President has Issued Executive Order Improving Critical Infrastructure Cybersecurity. Incidents like Stuxnet have drawn attention to the need for addressing cybersecurity in our plants as it has been demonstrated that in our new world, they are now a source of potential process safety incident. exida has highly experienced personnel in industrial control cyber security methods and techniques. exida provides customers with services covering the lifecycle, e.g. Risk Assessments, Equipment Cyber Evaluation Reports, NIST Gap Assessments, Vulnerability Assessments, Defence-in-Depth: Zone and Conduit Modelling (Electronic Security Perimeters), and more.

6 TOOLS & TRAINING exida has the world s leading tool for supporting safety lifecycle tasks (exsilentia ). exsilentia has its own embedded failure rate database, based upon 160 billion operating hours of failure rate information. Whether you are performing PHAs (PHAx TM ), LOPAs (LOPAx TM ), SIL Selection (SILect TM ), SIL Verification (SILVer TM ), SRS creation or Proof test TOOLS procedure development, cyber risk assessment or alarm rationalization, exida has a tool to suit, either as a standalone or part of an overall integrated suite that works seamlessly to provide the most comprehensive tool on the market today. You save time and money, while increasing efficiency and productivity. Once again, exida has you covered. FUNCTIONAL exida Academy provides comprehensive Process Safety, ICS Cybersecurity, and Alarm Management training for industry professionals, as well original equipment manufacturers. Our courses are available on a variety of platforms, from single day public courses to week long custom, onsite training workshops. Offering courses at the Beginner, Practitioner, and Expert levels, our goal is to share our evolving knowledge and skills with our students with the intention that they will use this knowledge to cost effectively design, build, operate, and maintain optimally safe and secure automation systems as applicable to their functional responsibility. exida Academy was built from the core foundation of exida s vision for excellence in dependable automation. SAFETY ASSESSMENT

7 POINT Zed: Assessments As part of the lifecycle, management of functional safety and cyber security is a requirement of IEC The standard lists 5 stages of assessment to help achieve compliance with the requirement. Although Functional Safety Assessment 3 (FSA 3) is to be performed as part of the pre-startup safety review (PSSR) as the minimum requirement, exida recommends that the five (5) Functional Safety Assessments (FSA), are carried out to ensure full compliance: FSA 1 after the hazard and risk assessment has been carried out, the required protection layers & security countermeasures identified and the Safety Requirements Specification (SRS) developed. FSA 2 after the SIS/ cyber security countermeasures have been designed FSA 3 after the installation, pre-commissioning and final validation of the SIS and cyber security countermeasures have been completed and operation and maintenance procedures developed. FSA 4 after gaining experience in operating and maintenance FSA 5 after modification and prior to decommissioning of a SIS/ cyber security countermeasures 8
