Explanation

Initial uncontrolled risk

Uncontrolled likelihood of occurrence

This refers to the probability or frequency of a particular event or hazard occurring without any interventions or controls in place.

The natural or inherent risk before any mitigation measures are applied.

Controls

What controls need to be in place to reduce the risk of the hazard causing a negative outcome?

Elimination
Removing the hazard from the workplace

Substitution
This involves replacing a hazardous material or process with a less hazardous one

Isolation
This involves physically separating or isolating the hazard from workers.

Engineering
These are physical changes made to machinery or the work environment that reduce the risk.

Administrative
These controls involve changes to the way work is organized and procedures are carried out. They often include training, standard operating procedures, safety policies, and regulations.

Change Practices
This involves changing the way a task is performed to make it safer.

It is similar to administrative controls but focuses more on actual work practices rather than overarching procedures or policies.

Residual controlled risk

Controlled likelihood of occurrence

This refers to the probability of frequency of an event or hazard occurring after appropriate control measures and interventions have been applied to safeguard employees and students.
