RISK ASSESSMENT
Version:
0.1
Next review:
Nov 2009
This form is to be filled in by the subject coordinator in consultation with the laboratory manager. Please refer to: CSU
Radiation Safety Committee (RSC) Manual and AS/NZS 2243 Safety in Laboratories Part 4 and Part 5.
All work must have approval from the CSU Radiation Safety Committee (RSC) prior to commencement.
For radiation work that ONLY involves solar ultraviolet exposure then complete the solar ultraviolet radiation form

Risk Summary & Conclusion (please tick appropriate)
The risk posed is insignificant and unlikely to increase during the course of the project.
The risk is significant, but will be effectively controlled.
There is uncertainty about the level of risk.
The risk is significant and cannot be effectively controlled.
Risk Evaluation
The project is to be reviewed annually, or whenever there is an incident or any significant change eg. new equipment,
personnel etc. This is to check that risk controls are still in place and working effectively.
