Dangerous Goods Storage and Handling Guidelines 6.2 Dangerous Goods Classes Dangerous goods are divided into nine classes according to their dangerous properties. Classes 1, 2, 4, 5 and 6 are further subdivided into sub-classes (e.g. 5.1, 5.2). In addition, goods in Classes 3, 4, 5, 6 and 8 are also organised into Packing Groups (PG) which indicate the degree of danger (PG I - great danger, PG II - medium danger, PG III - minor danger). Dangerous goods in any quantity must be stored safely and in compliance with the WHS Act and associated regulations. Dangerous goods above certain quantities must be notified to WorkCover. 6.3 Manifest Requirements Each area using, introducing or producing hazardous substances or dangerous goods is responsible to record these in the University manifest (Stock Holdings). Each of these products must also have relevant documentation including an SDS. The inventory should include: • product trade name and United Nations number • dangerous Goods Class and Packing Group • typical and maximum quantities held and the package sizes and supplier details, and • location of storage and point of use. Quantities above the “Manifest quantities” outlined in Appendix 1 are to be in licensed stores, such as an approved storage cabinet, which is fitted with an internal bund to contain any spillage. Flammables are to be stored away from ignition sources, and wherever possible avoid the internal storage of flammable and poisonous gases. Externally relocate gas cylinders and pipe supplies to point of use, and always secure gas cylinders in an upright position. WorkCover NSW is required to be notified for quantities exceeding the ‘Manifest quantities’ as outlined in Appendix 1. 7 Risk Assessment Once the hazards associated with the storage of dangerous goods are identified, a risk assessment should be undertaken to assess the level of risk of injury and then to implement risk controls in order to maintain legislative requirements and provide safe workplace. For the storage of dangerous goods below, the manifest threshold outlined in Appendix 1 and the requirements of the Code of Practice shall be implemented appropriately. Additionally the SDS for the dangerous good will act as the risk assessment for the storage, use and maintenance. Deviations from the requirements of the SDS will need to be recorded through the risk assessment form. Where the storage of dangerous goods is above the manifest quantity, a documented risk assessment needs to be undertaken. The risk assessment will take into consideration the following: • the quantity stored and in use • the extent of risk to people • the extent of risk to other substances, plant and buildings • factors contributing to the risk • types of controls required • priorities for implementing controls, and • identification of type of records required.

Dangerous Goods Storage and Handling Guidelines The risk assessment should reference the safety data sheet to identify risks associated with each dangerous good and use the Hazardous Substances Risk Assessment Form. The risk assessment process should also include a site map to indicate storage locations and quantities for licensing with WorkCover. E.g. Underground tank = 45,000 l of diesel at Facilities Management Division compound Flammable liquids roofed package store = 8,000 kg at building 31 Corrosives Cabinet = 250 l and Toxic Substances Cabinet = 100 l in Room 5:34 Where a laboratory has a quantity of substances, but with no more than a few litres or kilos in any one class, it is not necessary to notify WorkCover NSW. However, it is recommended that the laboratory be marked on a map for internal use as being a facility that holds a quantity of substances. A hazard warning sign must be displayed upon the laboratory doors (order form available from WHS website, laboratory safety). Other issues to consider might include; • spill response kits on hand, and PPE • provision of appropriate fire protection and fighting equipment • establish that containers are suitable and fully labelled (further information on labelling can be found in the Hazardous Substances Guidelines) • establish location of the Safety Data Sheets • establish if and when personal monitoring or health surveillance takes place, and • establish whether training has been provided to staff. 7.1 Review of Risk Assessments Risk assessments regarding the storage and use of dangerous goods must be reviewed as detailed in the UOW WHS Risk Management Guidelines. 7.2 Records of Risk Assessments Records must be kept of risk assessments developed in relation to the storage and handling of dangerous goods. These records should be kept in accordance with the UOW WHS Records Handling Guidelines. Records of results of risk assessments regarding the storage and handling of substances should be recorded by: • noting in the local manifest inventory if no specific control options are required to manage the risks associated with the storage or handling of the dangerous good, or; • preparing a report on the risk assessment if specific control options are required to manage the risks associated with the storage or handling of the dangerous good. 8 Risk Control Strategies The documented risk assessment should identify control measures to be implemented to minimise the risk to the lowest level as reasonably practical. Risk control must be achieved following the hierarchy of controls. Elimination should be considered as a means to control the risk, the best way of achieving this is to remove the hazard. If this is not possible the risk must be minimised using one or more of the other control options from the hierarchy. Risk control is to be conducted in accordance with the UOW WHS Risk Management Guidelines. Consideration should be provided for the following subsections.
