(1) Definitions of likelihood labels (1) Definitions of exposure variables Likelihood (Probability) Exposure E Level Descriptor Description Expected to occur Continuously or many times daily 10 A Almost certain The event will occur on an annual basis Once a year or more Frequently: Approximately once daily 6 B Likely The event has occurred several times or Once every three years Occasionally: Once a week to once a month 3 more in your career Infrequently: Once a month to once a year 2 C Possible The event might occur once in your career Once every 10 years Rarely: Has been known to occur 1 D Unlikely The event does occur somewhere from time Once every 30 years Very rarely: Not known to have occurred 0.5 to time E Rare Heard of something like the event occurring Once every 100 years (2) Definitions of likelihood variables elsewhere Likelihood L

(2) Definitions of consequence labels Almost certain: The most likely outcome if the event occurs 10 Likely: Not unusual, perhaps 50-50 chance 6 Severity level Consequences Unusual but possible: (e.g. 1 in 10) 3 V Catastrophe One or more fatalities and/or severe irreversible disability to one or more people Remotely possible: A possible coincidence (e.g. 1 in 100) 1 IV Major Extensive injury or impairment to one or more persons Conceivable: Has never happened in years of exposure, but possible (eg 1 in 1,000) 0.5 III Moderate Short term disability to one or more persons Practically impossible: Not to knowledge ever happened anywhere (e.g. 1 in 0. 1 10,000) II Insignificant Medical treatment and/or lost injury time <2 weeks I Negligible First aid treatment or no treatment required (3) Definitions of consequence variables Consequences C (3) Risk rating matrix Catastrophe: Multiple fatalities 100 Likelihood Consequence label Disaster: Fatality 50 label I II III IV V Very serious: Permanent disability/ill health 25 A Medium High High Very high Very high Serious: Non-permanent injury or ill health 15 B Medium Medium High High Very high Important: Medical attention needed 5 C Low Medium High High High Noticeable: Minor cuts and bruises or sickness 1 D Low Low Medium Medium High E Low Low Medium Medium High

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 S – Substitution variable risk calculator; En – Engineering Is – Isolation G – Guarding  In the comments box, describe the route of exposure and any other information (if applicable); Sh – Shielding  Specify the risk control type for each current or proposed risk control; A – Administrative T – Training In – Inspection  Provide a control description for each current or proposed risk control; M – Monitoring H – Health Monitoring  Where proposed risk control(s) have been identified complete a Health & Safety Action Plan; P – PPE  Determine the residual risk score referencing the same two variable risk matrix or three variable For information devising appropriate controls, refer to: Guide to Chemical Risk Hierarchy of Control. 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. Management representative HSR/Employee representative Employee(s) Employee(s) Employee(s) Employee(s) Person Responsible for implementation or escalation

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. Calium gluconate gel for dermal contact University of Melbourne and local area emergency procedures. Spill kits – vermiculite or attapulgite. Sodium hydrogen hydrogen carbonate or sodium anhydrous as neutraliser.

PPE Respiratory protection: AS/NZS 1715 Selection, use and maintenance of respiratory protective equipment Safety Glasses: AS/NZS 1337.1 Personal eye protection. Eye and face protectors for occupational applications Gloves: AS/NZS 2161.1 Occupational protective glove. Selection, use and maintenance Boots: AS/NZS 2210.1-9 (series) Occupational protective footwear or sturdy footwear as per local area requirements

To eliminate injuries always use the chemical in accordance with the manufacturer’s instructions and for its intended purpose only. All chemical users must have demonstrated competency and be familiar with the risk assessment and any SOPs prior to use of the chemical.
