Procedure

1. Introduction

Risk assessment is a technique for evaluating the likelihood that an incident will occur, and the probable consequences if it were to occur. Likelihood refers to the probability or chance that an incident will occur while consequence refers to the outcome of an incident in terms of injury, loss, damage or harm.

The aim of risk assessment is to establish the level of risk to enable the evaluation or judging of the acceptability of the level of risk. The objective of risk management is the reduction of the (level) of risk “as far as reasonably practicable” – to an acceptable level.

Hazards are things with the potential to cause injury, loss, damage or harm and are inherent to equipment, material, activities/tasks and processes. Equipment, material, activities/tasks and processes are therefore examined in detail through risk assessment, to identify –

Risk assessment provides a means for discovering and evaluating hazards to identify the hazards that must be controlled. Hazards can be controlled in two ways, namely:

Risk is a quantified combination of the abovementioned two factors. It is calculated by combining estimated values for the likelihood of an incident occurring and the severity of the consequence of an incident if it were to occur.

The formula for calculating risk is –

Risk (of a particular hazard) = Likelihood (of an incident occurring) x Severity (of a particular consequence).

Although the resulting risk value is a subjective estimation, it gives an indication of the risk level on which an evaluation or judgement of the acceptability of the risk can be based. Such a judgement is made during a structured risk assessment session by an informed group that includes persons actually exposed to the hazards.

how they could cause injury, loss, damage or harm (incident);

what the resulting injury, loss, damage or harm would be (consequence); how bad the injury, loss, damage or harm would be (severity); and

the probability/chance, with existing controls taken into account, that the injury, loss, damage or harm will occur (likelihood).

Limiting the chance (likelihood) of an incident occurring through preventive measures such as training, machine guarding, etc.; and

Limiting/controlling the consequences of an incident if it does occur, using fire extinguishers, first aid treatment, etc.

Procedure

The risk value also allows for the prioritisation of unacceptably high risks so that attention can immediately be focussed on critical/unacceptable risks, so that immediate and imminent danger can be treated first to prevent critical incidents from occurring.

The next level of risk is treated once the critical risks have all been dealt with. This phased approach ensures that risks are treated and eliminated methodically, according to their criticality.

2. Definitions

Consequence The outcome(s) of an incident in terms of injury, loss, damage or harm

caused

Hazard

An energy source, situation, substance or act with a potential for harm in terms of human injury, ill health or damage to equipment or the environment, or a combination of these

Incident

The occurrence of an event where the specified hazard causes injury, loss, damage or harm because of the release of or contact with the hazard

Likelihood Risk

The probability or chance that an incident will occur

A value expressing the combination of the likelihood of an incident occurring and the severity of the consequences of such an incident

Severity

An indicative value of the seriousness/severity/degree of harm of the consequence of an incident

Acceptable risk Hazard Identification Risk assessment

3. Guidance for Implementation

Risk assessments, through the identification of hazards and an analysis of the risk it presents, indicate where EHS management efforts have to be focussed and therefore play

Risk that has been reduced to a level that can be tolerated having regard to the OH&S Policy an legal obligations

Process of recognizing that a hazard exists and defining its characteristic. Process of evaluating risk(s) arising from a hazard(s) taking into account the adequacy of any existing controls, and deciding whether or not the risk(s) is acceptable.
