Risk Assessment title: Genomic DNA extraction using Sigma GenElute Blood Genomic DNA Kit
Step 1: Identify the activity
Describe the activity:
This Risk Assessment describes the extraction of genomic DNA using extraction kit from Sigma
Describe the location:
Cancer Care Lab, Rm 3.20, Level 3., Research & Education Centre, 4-10 South St., Kogarah. NSW 2217.
Step 2: Identify who may be at risk by the activity
The person carrying out these procedures are at risk.
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.

What you need to do
1. Consider what can go wrong that can hurt someone
2. Determine what the most likely outcome would be - Consequences

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.
