Hazardex 2019 Conference Presentations - The Role of Combustible and Toxic Gas Detectors in Plant Safety 21 November 2018

There can be confusion between equipment for process gas monitoring and gas detection systems for life safety. Life safety systems mitigate risks stemming from leaks of toxic and/or combustible gases, help prevent explosions and harm to workers caused by leaking gas, and in turn, reduce costly downtime. ...

Hazardex 2019 Conference Presentations - Using Equipment Protection Levels (EPLs) to break the chain. 20 November 2018

It is clear that a hazardous area classification plus equipment selection does not constitute a complete risk assessment because an assessment of the consequences is not included. EN IEC 60079-10-1 reflects this and states,” Subsequent to the completion of the area classification, a risk assessment may be carried out….”. It then goes on to suggest that as a result of the risk assessment the required EPL may be higher or lower than normal....

Hazardex 2019 Conference Presentations - Eliminating explosion risks through properly sealed cables 20 November 2018

This report was commissioned in order to establish the correct type of cable gland for a particular type of cable construction when used in Zone 1 and Zone 2 hazardous areas. This resulted into an investigation and testing program to establish if selecting cable glands using the guidance from IEC 60079-14 Electrical installations design, selection and erection - is in fact safe for flameproof applications using cables typically used in marine and off-shore.&nb...

Hazardex 2019 Conference Presentations - Risk Management & Engineering Judgement: 4 Shades of Grey 20 November 2018

The effective exercising of engineering judgement may be identified as one of the hallmarks of the true professional engineer.  But in embracing this notion, there is perhaps a danger that individual engineers may become over eager to exercise their judgement in demonstration of their professionalism.  ...

Hazardex 2019 Conference Presentations - Case study on a failure to understand and manage risks 20 November 2018

This paper presents a case study of an incident that occurred outside the traditional area of process safety, although the circumstances and the learnings are highly relevant to the high hazard process industries.  Key areas of failure include leadership, accountability, risk assessment, following established procedures, management of change, consideration of off-site impacts, and emergency procedures. ...

Hazardex 2019 Conference Presentations - Barrier-based learning from incidents 20 November 2018

Effective learning from incidents is critical for any organisation. The reasons leading to many incidents with an organisation are often not new as incidents are repeat events or events that are very similar in nature to previous incidents. Incident analysis is an essential form of generating realistic feedback on the quality of an organisation’s barriers. ...

Hazardex 2019 Conference Presentations - Hazardous Area Classification Chemical Plant Case Study 19 November 2018

It is important that care is taken when determining hazardous zones. The consequences of applying the wrong technique are clear: hazards can be underestimated and inadequately controlled, or can be overestimated resulting in prioritisation in the wrong places. This paper explains methods to overcome this challenge using a case study from a chemical manufacturing site currently revising its hazardous area classification....

Hazardex 2019 Conference Presentations - EI Not Permanently Attended Installation Guidelines 19 November 2018

In June 2010 the Energy Institute issued the first edition of the Not Permanently Attended Installation (NPAI) guidelines. The document sought to provide best practice guidance on issues of safety, welfare and the environment consistent with optimising the benefits of NPAI’s for the international petroleum industry. The EI and DNV GL have recently revised the NPAI Guidelines to more accurately reflect current international best practice....

Hazardex 2019 Conference Presentations - Security Risk Assessments for Functional Safety 19 November 2018

Safety Instrumented Systems (SIS) are more vulnerable today than ever before due to the prevalence and sophistication of attacks specifically targeting them. This presentation will break down the requirements of BS EN 61511:2017 2 nd  Edition in the context of IEC, ISA, API and NIST requirements. ...
