2.1 Classification of the substance or mixture

To find this information on your SDS, see Section 2: Hazards Identification. – the UN class and packing group – the substance state (gas, liquid or solid) – information about flammable liquids: - container size - whether the container is open or closed. Container size and type can affect the controls you must comply with. For example, you will need a location compliance certificate for flammable liquids if you store: – 50 L or more in an open container – 100 L or more in closed containers larger than 5 L – 250 L or more in closed containers up to 5 L. Preparing your inventory First steps You will need your Workbook to gather information about your substances that you will input into the Calculator. The Workbook is available at: www.hazardoussubstances.govt.nz Take a look around your workplace and record all of the hazardous substances in it. Read the SDS for each hazardous substance you identified. From the SDS, put the required information into the Workbook. Complete any remaining fields in the Workbook. Table 1 at the back of this guide is an example that may help you prepare your inventory. Using the Calculator You can also use the Calculator to prepare your inventory. When you open a new inventory using the Calculator, it will give you a personal identification number (PIN) that will let you access and edit the inventory online. Keep this PIN safe, or you will lose access to your inventory. WorkSafe will not be able to reset this PIN for you. You can use the Calculator to email the PIN to yourself. enter all of the information about your substances requested by the Calculator. After you have entered your substances, they will be saved as an inventory, which the Calculator can print. The Calculator will also tell you the controls that apply to your substances. How to keep and use your inventory What kind of inventory should you have? Your inventory can be a paper or an electronic document, such as a database or spreadsheet on a PC, tablet or phone. It can also be created, edited and accessed online using the Calculator. If you have an electronic inventory, make sure you have a backup (eg a printed copy, or a copy on a device like a memory stick). This back up needs to be readily accessible to emergency service workers. Where should you keep your inventory? You must keep your inventory at your workplace and make it readily accessible to any emergency service worker attending the workplace during an emergency and after the workplace has been evacuated. emergency service workers need to know what hazardous substances are at the workplace to decide how to deal with any emergencies. Remember: It is useful to have hard copies of your inventory available on site for quick access in an emergency. You can also provide copies to your local branch of Fire and emergency New Zealand. Do your workers need to access the inventory? While your workers do not need to have access to the inventory, they must be able to access SDS and understand the safety information they contain. This could mean giving your workers the key safety information in another way (eg in product safety cards). Check with your supplier if product safety cards are available for the hazardous substance. See our Guide to Safety Data Sheets in the Workplace for more information. Keeping your inventory up-to-date You must maintain your inventory so that it is correct and up-to-date. You need to update your inventory whenever there is a change to the information that is kept in it, such as the substances or maximum amounts likely to be at your workplace. You will also need to update your inventory if the information on the SDS changes (eg the recommended segregation or storage requirements) or you move substances to a different location. When you update your inventory, you should also review and, if needed, update your control measures. For example, you may have a new substance that needs to be stored inside secondary containment. When don’t you need to keep an inventory? You don’t need an inventory for hazardous substances that are also consumer products used at the workplace in amounts similar to those used at home, for example household cleaning products sold in supermarkets. You don’t need an inventory for hazardous substances in a transit depot or designated transfer zone. This is because goods in transit remain in their packaging and are subject to the Land Transport Rule: Dangerous Goods 2005.3 However, the PCBU with management or control of the transit depot or transfer zone must be able to provide a list of hazardous substances and the quantity of each substance to emergency service workers when requested. A final example of when you do not need to keep an inventory of hazardous substances is if your workplace is a small scale laboratory where hazardous substances are used in research and development, teaching or analytical testing. In this case, you only need to keep a record of: – hazardous substances that need tracking – any substances likely to be hazardous substances that are not approved. 3 www.nzta.govt.nz/resources/rules/dangerous-goods-2005-index MAXIMUM LIKELY AMOUNT Required information 45 10 6 180 kg L 02) goods cage LOCATION (eg Goods Storage Flammable Required information Flammable cabinet Cabinet, Room Flammable cabinet substances.
