Hazard = A property of a substance, activity

• r situation that has the potential to cause

harm. Risk = The probability that the harm linked to a hazard will actually occur, taking into account also the severity of that harm.

Acceptability of Risk

Risk Score Risk Level Acceptability

• f Risk

Recommended Actions <3 Low Risk Acceptable No additional risk control measures required. To continue to monitor to ensure risk do not escalate to higher level. 3 – 4 Medium Risk Moderately Acceptable Acceptable to carry out the work activity; however, task need to be reviewed to bring risk level to As Low As Reasonably Practicable. Interim control measures such as administrative controls can be implemented. Supervisory oversight required. >4 High Risk Not Acceptable Job must not be carried out until risk level is brought to at least medium risk level. Risk controls should not be overly dependant on personal protective equipment. Controls measures should focus on Elimination, substitution and engineering controls. Immediate Management intervention required to ensure risk being brought down to at least medium level before work can be commenced.

What is the hazard? What is the likelihood of exposure? What are the consequences of exposure?

RISK Likelihood Consequences

The evaluation of risk is highly related to the “Risk acceptance”. Risk evaluation and acceptance can vary with culture, experience, resources, management, and even current events.
