1 Use this form to assist you to complete risk assessments for hazardous activities and processes. Any serious or ongoing hazards should be reported via RiskWare to ensure that appropriate corrective actions are tracked and completed. Faculty/School: Faculty of Pharmacy Initial Issue Date: Oct 2016 Risk Assessment Reference Number: Next Review Date: Oct 2017 Risk Assessment Name: Biosafety II cabinet operations Prepared by: Padmaja Dhanvate & Dr. Alpesh Patel Responsible supervisor/s: Research supervisors, Laboratory managers Identify the activity and the location Activity or process: Use of a class II biosafety cabinet Location: S208, S222, N257, N273, N423, N431 Identify who may be at risk This may include fellow workers, students, visitors, contractors and the public Persons at risk: All staff and students who use the Class II BSC Risk assessment team (Who was consulted?): Laboratory and Research Services Manager List of Legislation, Code of Practice, Australian Standards, Guidance Materials used to determine control measures Refer to SWP Use of Class II biosafety cabinet, follow SWP for waste disposal and other relevant SWPs. Risk Assessment Methodology Assessing the risk is a brainstorming exercise, which is most effectively carried out in a team environment with the people to complete the activity or process. Most activities or processes are broken down into a variety of separate tasks. For each task, consider the hazards, the potential harm or negative outcomes and the conditions for those negative outcomes to occur. Whenever assessing the health and safety risks associated with a task, always consider the following primary risk factors. The physical activities to complete the task e.g. repetitive movement, high force, physical exertion, awkward posture The work environment e.g. lighting, work layout, traffic, thermal comfort, working in isolation The nature of the hazard itself e.g. working with chemicals, microorganisms, radiation, machinery, potentially violent clients The individual workers involved, e.g. level of training, skills, experience, health, age, physical capacity The information gathered from the risk assessment process must be used to develop a Safe Work Procedure (SWP).

2 Task or scenario Hazard/s Associated harm, e.g. what could go wrong? Existing Risk Controls Current risk rating Use the Risk Matrix Any additional controls are? 1 Residual risk rating Use the Risk Matrix Handling of GMOs and infectious organs Infection and/or release with pathogens and GMOs into the environment Infection with and release of GMOs and pathogens Correct training of personnel in the use of class II biosafety cabinet, personal protective equipment; follow specific SWPs for pathogens and GMOs Use of Bunsen burner or other source of open flames Fire in cabinet Burns, spread of fire Bunsen burner and other sources of open flames are not permitted inside a class II cabinet Use of 80% ethanol and other flammables Fire in cabinet / explosion of cabinet Burns, spread of fire, explosion Avoid using ethanol in cabinet (use non-flammable disinfectant); if ethanol is use squeeze bottle (spray bottles are not permitted) and limit amount UV light Burns to eyes and skin Blindness, burns All cabinets should be equipped with safety switch that prevents UV light from being activated while cabinet is open Workers with pre-existing conditions (allergies, immunocompromised status) and pregnant workers Increased risk of allergic reactions, severe infection including those of the unborn, pathogens could cause malformation and death of the unborn. Allergic reaction, infection Workers with pre-existing conditions and pregnancy are not permitted to work with pathogens unless approval has been obtained from WHS services 1. Always consider whether or not it is possible to eliminate the hazard or hazardous task altogether. If its not possible refer to the hierarchy of risk controls.

3 Implementation of Additional Risk Controls Additional controls needed Resources Responsible person Date of implementation RiskWare Reference Safe Work Procedure (SWP) DONE Sarah Cui Train workers to complete process in accordance with SWP Time supervisor and workers Supervisor University and local WHS training Time Supervisor List emergency controls for how to deal with fires, spills or exposure to hazardous substances and/or emergency shutdown procedures Follow general emergency and spill procedures. Ensure that emergency equipment (eye wash, emergency shower, fire extinguisher are in place and working / have been tested. Ensure disinfectant and spill kit are in place and complete. In case of exposure to hazardous and infectious substances submit RiskWare incident. Follow hazard-specific procedures listed in respective SWP REVIEW Scheduled review date 1 year 2 years 3 years Are control measures in place (YES/NO) Are controls eliminating or minimizing the risk (YES/NO) Are there any new problems with the risk (YES/NO) Reviewed by: Actual Review date:
