Examples: • Death or serious injury due to fire, explosion or dangerous

chemical release

• Major damage to structure or plant (including a well blowout)

• Collision of ship or helicopter with the installation

• Failure of diving operations’ life support systems

• Any other event involving death or serious injury to multiple people

• Any major environmental incident resulting from any of the above

What is a major accident?

Paraphrased from the HSE in Safety Case Regulations (2015)


5

Major Environmental Incident:

An incident which results, or is likely to result, in significant

adverse effects on the environment

A Major Environmental Incident must have another

safety related major accident as a precursor

Major Environment Incident (MEI)


6

Examples of Major Accident Hazards include:

Major Accident Hazard (MAH)


7

• How do we prevent a major accident?

• If the worst does happen, how do we minimise

the danger to people?

DISCUSS

PROCESS

PEOPLE

PLANT

Set standards and expectations through

management processes and procedures

Establish a good organisational culture (i.e. the

values adopted, the way people behave and the

functions they perform) and are competent and

authorised to perform work on safety critical devices

Provide suitably designed and constructed

plant. Maintain this plant to a suitable

condition

Prevention of major accidents

Corporate Major Accident

Prevention Policy (CMAPP)

The CMAPP outlines our commitments to:

• Leadership and Culture

• Competency and Training

• Asset Integrity and Maintaining Safe Operations

• Assurance

The CMAPP is on BMS and can be

accessed by clicking here

.

All of those who work for, or with, Centrica are required to

understand and comply with our CMAPP

Barriers to a major accident


11

Safety and Environmentally

Critical Elements (SECEs)

• Parts of an installation and its plant (including computer systems) which: a) the failure of which could cause or contribute substantially to a major accident or major environmental incident

b) the purpose of which is to prevent, or limit the effect, of a major accident or major environmental incident.

• SECEs are the essential components which prevent or limit the effects of a major accident. The failure of an SECE could cause or contribute to a major accident.

Note: for installations yet to transition to the new Safety Case

Regulations 2015, these are termed Safety Critical Elements

(SCEs)


12

SECE Examples

1. Hydrocarbon containment

(prevention)

2. Gas / flame detectors (detect)

3. Emergency Blowdown (control)

4. Temporary refuge integrity

(mitigate)

5. Lifeboats (TEMPSC)

(rescue / escape)

5

For each SECE there will be a performance standard which

sets the minimum level of operation of the SECE


13

How do we know these SECEs meet

their Performance Standards

• Each SECE must reliably perform its function to the

requirements defined in its Performance Standard

• Maintenance Routines ensure that SECEs continue to

perform to their PSs

• An Independent Competent Person (ICP) is appointed

by the Duty Holder to double-check our SECEs are

working

• This is a legal requirement

Summary

Activity

When watching the following video, ask yourself:

1. What are the hazards?

2. What are the potential consequences?

3. What is the SECE in question?

4. What aspect of the performance standard fails?

5. What failure occurs in terms of plant, process and

people?
