What is Alarm Management? “Process by which alarms are engineered, monitored, and managed to ensure safe, reliable operations”
What else is Alarm Management? • Continuous lifecycle • Plant maintenance/reliability • Good process control • Outcome of a risk assessment • Related to equipment failure • A form of Enhanced/Advanced Control • Abnormal Situation Management • It has been “widely ignored” for a long time
What is a Lack of Alarm Management? Example: Texas City Oil Refinery 2005. Precursors: - Maintenance cut by 25% - Only one Control Room Operator for the whole plant - Failed level switches - Level transmitter reading incorrectly – no alarm - Workers within exclusion zone - Decided against installing safety flares Outcomes: - 15 people killed - Could have spent a couple of $m but ended up costing $1.6b - Oil Refining industry are now relatively proactive in AM (Ref.) http://www.texascityexplosion.com/
Alarm Management: It’s about Safety! Documented financial losses estimated at $1.5 billion OSHA leveraged fines for this incident exceeded $87MM
An Example Plant Incident • Plant is unstable, getting towards end of 12hr shift • Tank containing hot material reaches HH level • Trip on HH level interlock was disabled to replace the instrument and inadvertently not re-enabled • Operator misses the alarm because he/she is overloaded and there is an alarm flood • High level safety switches that trip the incoming pump have not been tested for over two years and fail to operate • Tank overflows and severely burns worker below
Possible Outcome Employee Impact • Possible Injury • Potential Fatality • Flow-on Family/Community effects Employer Impact • Operational Downtime/Loss of Production • Investigation by the relevant authority • Expert Witness in Court • 1st Question to Employer: “Did you comply with an ISA Standards or Internationally accepted Standard”? • 2nd Question to Employer: “Did you follow known, good engineering practice”? In recent cases there has been more use of expert witnesses. What would an expert witness say in this case?
Key Features – ISA 18.2 • Large focus on an Alarm System Lifecycle • Clear Alarm System Performance KPIs • Section on compliance • Alarm Philosophy – what must be included • Alarm System requirements Specification • Identification • Rationalization • Advanced Methods • Less examples are given • Complimentary to EEMUA 191

Alarm Management is now a Compliance Issue • Compliance: ANSI / ISA SP18.2 • Similar to ANSI/ISA S84.01: • nationally recognized standard • qualifies as a nationally recognized standard for safety systems such that OSHA recognizes as “recognized and generally accepted engineering practice” • Not a requirement to meet OSHA 1910.119 PSM requirements but bears substantial weight with regard to implementing safety/alarm systems • burden of proof is on the User to demonstrate that they have followed generally accepted engineering practice
ISA 18.2 Compliance. • Section 4.1: Conformance Guidance To conform to this standard, it must be shown that each of the requirements in the normative clauses has been satisfied. • Section: 4.2 Existing Systems (Grandfathering Clause) For existing alarm systems designed and constructed in accordance with codes, standards, and/or practices prior to the issue of this standard, the owner/operator shall determine that the equipment is designed, maintained, inspected, tested, and operated in a safe manner.
Historical Findings • Industry estimate: $10 Billion per year from abnormal situations • Incident costs from $100K-$1 Million per plant per year • Refineries suffer a major incident once every three years costing $80M • Insurance companies show industry claims >$2.2 Billion per year due to equipment damage (North America) ASM Consortium Findings
Personal Observations. • Many process plants in North America are not doing enough • Alarms form part of your plant’s layer of protection • There will be more prosecutions for OH&S breaches
What Steps Can You Take? • Senior Management Sponsorship • Purchase ISA 18.02 • Undertake an audit of your alarm system. Minimum do Monitoring and Assessment • Prepare a Philosophy Document and then Functional Specifications • Prepare a Strategic Plan • Just Do it
