Risk Assessment title: Delivery of Compressed Carbon Dioxide to Level 4, Research & Education Centre via Lift
Step 1: Identify the activity
Describe the activity:
1. The Delivery person transports two full G Size Cylinders of Compressed Carbon Dioxide to the Lift entrance
2. The Delivery Person goes to Level 4 via lift
3. A staff member pushes the full G Size Cylinders of Compressed Carbon Dioxide into the Lift and sends the lift to Level 4.
4. The Delivery Person removes the full G Size Cylinders from the trolley and secures them with restraints.
5. The Delivery Person places the empty cylinders on the trolley and returns to the Ground Floor via the Lift
6. The Delivery Person loads the empty cylinders into the truck at the Loading Dock
Describe the location: Plant Room, Level 4, Research & Education Centre and Ground Floor Loading Dock, Research & Education Centre

Step 2: Identify who may be at risk by the activity
The Delivery Person, Cleaners if they are in the loading dock at the time of delivery, Staff / students who may be in the Lobby at the time of moving the cylinders or who work/study in the offices close to
the Loading Dock, Staff / Students from Level 3 Research & Education Centre who assist with the Delivery of Compressed Carbon Dioxide.
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.

Required action
Act immediately:
The proposed task or process activity must not proceed. Steps must be taken to lower the risk level to as
low as reasonably practicable using the hierarchy of risk controls.
Act today:
The proposed activity can only proceed, provided that:
(i) the risk level has been reduced to as low as reasonably practicable using the hierarchy of
risk controls;
(ii) the risk controls must include those identified in legislation, Australian Standards, Codes of
Practice etc.
(iii) the risk assessment has been reviewed and approved by the Supervisor and
(iv) a Safe Working Procedure or Safe Work Method has been prepared.
(v) The supervisor must review and document the effectiveness of the implemented risk
controls.
Act this week:
The proposed task or process can proceed, provided that:
(i) the risk level has been reduced to as low as reasonably practicable using the hierarchy of
risk controls;
(ii) the risk assessment has been reviewed and approved by the Supervisor and
(iii) a Safe Working Procedure or Safe Work Method has been prepared.
Act this month:
Managed by local documented routine procedures which must include application of the hierarchy of
controls.
