MISSION ANALYSIS &

RISK ASSESSMENT

Objectives

To list down the safety culture adopted by industry

To discuss The Basic management System

To understand Bow tie Process

To discuss the term “ALARP”

Safety Culture

Generative:

Proactive:

Calculative:

Reactive:

Pathological:

“We do things well, or we don’t do them”

“We work on the problems we still find”

“We have systems in place to manage all

hazards”

“Risk Management is important, we do a lot every time we have an

incident”

“ Who cares as long as we not caught”

Management System

Risk Evaluation and Management

Not separate but integral

Risk Evaluation and Management

Stakeholders/Clients Demand Expectations about risks have

change

Organisations to have their risk management on track.

Bow Tie helps you to organise your risk management in a way that is easily explained

Introduction

Bow Tie is a generic methodology that can be of value to analyse and manage all kinds of major risks

Bow Tie originated in the area of Health, Safety and Environtment (HSE) and has proved it’s value for all kind of business risks.

Risk Management Process

Bow Tie Process

Risk

Identify risks (What do we mean by risk?)

Risk = Probability x Consequence

Risk Matrix

Bow Tie

Step 1 – Identify the Hazard

Hazards

EXAMPLE?

Step 2 – Identify The Top Event

Top Event

EXAMPLES:

oLoss of ContainmentoStructural FailureoDropped ObjectoLoss of ControloElectrical Shock

oFalls to same LeveloFalls to Lower LeveloOxygen DeficiencyoLoss of Separation

oContact

Step 3 – Identify threats

THREAT

EXAMPLES

Thermal – High TemperatureChemical – corrosionBiological -Bacteria/Marine growthRadiation – UltravioletKinetic – FatigueElectrical – High VoltageEnvironmental Condition – poor visibility/storm/eathquakeUncertainty – design unknownsHuman Factor - incompetence

Step 4 – Identify consequences

CONSEQUENCE

Step 5 – Identify Threat Barriers

Step 6. Identify Recovery Measures

Recovery Measures

Step 7. Identify Escalation Factors“How might controls fail?”, “How might their effectiveness be

undermined?”

Step 8. Identify Escalation Factor

Controls “How might controls fail?”,

“How might their effectiveness be undermined?”

Step 8. Identify Escalation Factor Controls

“How do we make sure controls don’t fail?”

Risk Management

Effective Risk Management is only possible if PEOPLE are assigned responsibilities for CONTROLS

Risk Management

You cannot ‘buy’ risk management, you cannot delegate risk

management to a ‘group over there’, it has to become part and parcel of

your overall culture
