Step 1: Identify the activity
Describe the activity:
Each load is validated with a chemical indicator strip MMM1250 from Livingstone.
The autoclave is validated with a biological indictor 1261P from Livingstone, at least once a month
Turning on autoclave
load autoclave trolley
Checking the stability of goods on the trolley
Place a chemical indicator strip into the load, vary the position each load.
If PC2 waste, remove gloves and place them in one of the buckets to be autoclaved, Re-glove.
Inserting trolley into autoclave
Check the position of the trolley in the autoclave, making sure it does not damage the sensor
Close the door
Choosing autoclave program,
Making sure the cycle is completed before opening the door. Beware of hot steam when opening the door.
Remove the trolley from autoclave. The trolley and its contents will be hot so care must be taken.
Close the autoclave door
The chemical indicator strip is checked: Strip kept and taped into the records book with the date and load type indicated.
Unload autoclave trolley and sort into what needs to go to the drying ovens and what can be placed into the group trolleys.
Wet glassware is placed in the drying ovens
Laboratory autoclave is placed in their trolley for collection
PC2 waste is then placed into a black plastic bag and is removed from the building as domestic waste.
Mop up any water that drips from the trolley
Two people are to move the 660l Silo bins from the Lowy building to the collection area at the back of the Biological Sciences building, though the connecting tunnel.
Describe the location: Lower Ground wash-up area
Step 2: Identify who may be at risk by the activity
A number of people may be at risk from any activity. This may affect the risk controls needed. These people may include fellow workers, visitors, contractors and the public. The location of the activity
may affect the number of people at risk.
The people working in the wash-up area, visitors and contactors.
Steps 3 to 7: Identify the hazards, risks, and rate the risks
1. An activity may be divided into tasks. For each task identify the hazards and associated risks.
2. List existing risk controls and determine a risk rating using the UNSW Risk Rating Procedure.
3. Additional risk controls may be required to achieve an acceptable level of risk. Re-rate the risk if additional risk controls used.

Step 10: Monitor and review the risk controls
It is important to monitor risk controls and review risk assessments regularly. Review is required when there is a change in the process, relevant legal changes, and where a cause for concern has
arisen. Reviews could be scheduled on an annual basis. If the risk assessment has substantially changed a new risk assessment is warranted.
