Definition-Residual Risk

ReductionA process that involves a study to:

Analyze jobs Identify hazards and existing controls

Determine the level of risk

Identify controls to reduce risk Measure the amount of risk reduction

Some Facts About Risk

An inherent feature of systems; a qualitythat always exists to some degree

Is definable in terms of three factors(Frequency, Likelihood, & Severity)

Once it is defined, it can be quantified

The quantity of risk can be changed bychanging these factors


4/42

The Risk Factors

Frequency (Exposure Opportunity)

How often the exposure exists

Likelihood (Chance of Occurrence)

Severity (Degree of Harm) Worst Plausiblescenario

Risk = F x L x S

The quantity of risk can be changed bychanging the risk factors

Eliminating a step

Changing how a step is done

Implementing new/revised controls

R3 Analysis

Define the

F-L-S scales

Define the system to

be studied

(Activity)

Identify the

concerns to

be analyzed

(Incidents)

Score each concern

on the F-L-S scales

Identify/Analyze

controls

Identify

New

controls

Implement the new

controls

Re-score the

concerns with

the new controls

Report the R3

as a Safety

Outcome!

Other R3 Examples

Handling Chicksan pipe

Vehicle traffic flow pattern in an oilfieldyard

Climbing on/off of vacuum tank trailers

Working on a burn table at a mfg plant

Changing catalyst in a cat cracker Access to bucket truck by Linemen

So Whats In It For Me?

R3 provides a means for examiningsystems

R3 gets the people closest to the risk in

systems involved in its reduction It illustrates how interventions affect risk

It provides both upstream & downstream

measures for safety efforts R3 motivates action to reduce risk from

hazards in systems
