STEP 3 – REVIEW CHEMICAL PROCESS
For each stage of the chemical risk assessment:
Hierarchy of Control (Control Type)

Review the prompts/examples for each route of exposure for each category;
El – Elimination

Determine and record a raw risk score by referencing the two variable risk matrix or the three variable risk calculator;
S – Substitution

In the comments box, describe the route of exposure and any other information (if applicable);
En – Engineering

Specify the risk control type for each current or proposed risk control;
Sh – Shielding

Provide a control description for each current or proposed risk control;
A – Administrative T – Training

Where proposed risk control(s) have been identified complete a Health & Safety Action Plan;
M – Monitoring

Determine the residual risk score referencing the same two variable risk matrix or three variable risk calculator used to determine the raw
risk score.

STEP 4 – IMPLEMENTATION AND CONSULTATION PROCESS
Determine the person responsible for reviewing and implementing the risk assessment including the identified controls. Ensure a Health & Safety Action Plan has been completed, reviewed and signed off where
proposed controls have been identified.
Obtain the authorisation of the management representative.
Ensure the HSR (if applicable) has been consulted. Ensure the employees undertaking the activity have been consulted.
Record below the names of the persons consulted.

Extra writing room - use this page to enter extended comments or descriptions
Review:
Review risk assessment every 3 years.
Review employee chemical procedures during workplace inspections.
Review risk assessment where there is an incident with the chemical or new information becomes available.
Review risk assessment when the MSDS/SDS is updated/reissued.
Emergency and First Aid procedures
Ensure that general first aid procedures and resources are in place and available.
First aid risk assessment and procedures that take into account the risks associated with the chemical and possible adverse outcomes.
University of Melbourne and local area emergency procedures.
PPE
Disposaable gloves when cleaning up leaks.
To eliminate injuries always use the chemical in accordance with the manufacturer’s instructions and for its intended purpose only.
For use in conjunction with the OHS risk management procedure and the Chemical risk management procedure.
