TERMINOLOGY

RISKEffect of uncertainty on objectives

Effects positive or negative deviations fromwhat is expected.

Uncertainty Lack of information,understanding or knowledge of an event, itsconsequence, or likelihood.

Objectives - financial, production, operational,HSE goals that are strategic, corporate,project, product or process driven.

ISO Guide 73/ ANSI Z690

TERMINOLOGY

RISK

Combination of the likelihood of an

occurrence of a hazardous event orexposure(s) and the severity of injuryor ill health that can be caused by the

event or exposure(s).

low as reasonably achievable.

"as low as reasonably achievable"or "ALARA" means, in reference

to a substance, that measuresmust be taken to keep a worker'sexposure to a level as low as isreasonably achievable;

WHY USE A RISK-BASEDAPPROACH ?

Standardizes risk managementgoals and methods to be used =increase in process efficiency.

Consistent framework that can beused by all business units andwork groups = increase in process& employee effectiveness.

Due Diligence (defensible).

RISK ANALYSIS: LIKELIHOOD

Frequency of Exposure Probability Loss = Likelihood

FREQUENCY OF EXPOSURE:

4 - Frequent (5+ per week/job)

3-

Occasional ( 1+ per week/ 3+ per job )2 - Rare ( 1+ per moth/ 2+ per job)

1 - Very Rare (1+ per year/job)

PROBABILITY OF LOSS:

4 - Expected/Likely (Happens often; > 1 per year)3 - Probable/ Occasional (1 occurrence in 3 years)

2 - Possible/Rare ( 1 occurrence in 5 years)

1 - Remote/Very Rare (Once in the life of the facility or

company)

RISK TREATMENT OPTIONS

Avoidance choose to not performthe task or work activity.

Elimination Remove the hazard(i.e. design valve handles to beaccessible at floor level)

Substitution Use a less harmfulsubstance (solvent replacement for

Toluene/Xylene/Varsol).

Share the Risk hire competentpersonnel to perform the task

RISK TREATMENT OPTIONS

Engineered Guards, Ventilation,Interlocking isolation systems(pipelines), Ergonomic equipment

Administrative Safe WorkProcedures, Practices, Rules,Training, Job rotation/schedule.

(Based upon IEC/ISO 31010:2009)

HAZOP, What if, FMEA/FMECA, FTA,HACCP, Root cause analysis, etc.
