What to Do – Focus on Barrier Management

▪ Barriers need to work when we need them to work▪ It is everyone’s responsibility

MY SCE IS WORKING AND I

KNOW IT

• I know the Barriers

• I know my Role

• I keep them healthy

• I can prove it

Challenges in Barrier Management

Clear line of sight to Major Accident HazardsClear roles & responsibilitiesRegular engagements and

collaboration

• Active use of e.g. Hazards & Effects Register, Bowties

• HSE Case mindset embedded into “business as usual” e.g. into Learning From Incident, Management of Change, Permit to Work

• Understand how HSE Case benefits the business

• Convince and align stakeholders

• Consistent approach and messages

• What else can go wrong? What’s new? What has changed?

• Monitor barrier effectiveness through Process Safety Performance Indicators

• Assurance on Process Safety Performance

Barrier Effectiveness: It is everyone’s responsibility

Barrier Owner

• SCE meet the design /

functional intent

• Monitor SCE compliance

• Analyze SCE performance

Executor

• Perform the assurance

task

• Report outcome

• Highlight deficiencies

Technical Authority

• Set the requirement of

SCE and acceptance

criteria as per PTS /

code and standard

What are SCEs?

Simply put: SCEs are barriers put in place to prevent and/or limit the effect of a hazard with Major Risks

SCEs are Barriers

SCEs are to create FOCUS

- the failure of which could cause or contribute substantially to Major Accident Hazard (MAH)

- a purpose of which is to prevent, or limit the effect of a major accident”

Safety Critical Elements (SCEs) are Parts of an installation and such of its structure, plant equipment and systems (including computer program) or any part thereof:

Execute/ Review and Implement Assurance

Identify Major Accident and SCE Develop Performance Standard

Safety Critical Elements (SCE) Identification with Bowtie and Flowchart 1

Are SCEs (Barriers) by Themselves Good Enough?

Why?

Because SCEs need to perform as required when

needed – they must be maintained to prevent the holes

from aligning.

SCE without an associated Assurance/Maintenance Activity is not a Barrier.

Good Design/Operation Integrity

• Less holes

• Minimizes time of temp holes exist

• Limits holes size

Poor Design/Operation Integrity

• Increases holes

• Increases the time of temp holes exist

• Increases holes size

The ‘holes’ in the cheese represent the weaknesses in the barriers, leaving them ineffective in the role as a risk control system.
