1 Managing Waste Chemicals for Disposal

2 Purpose & Content Define the process for managing waste chemicals on site: Key Legislation: Cost: Curtin University Procedures

3 Outcomes Participants should leave this presentation with an understanding of: key legal requirements covering chemical waste disposal the cost basis for collection and disposal of chemicals key requirements for managing chemical wastes on site their obligations and role in support of the process opportunities to improve the process The contractors system for preparing for and managing the collection of chemical waste

4 Key Legislation There are 4 key legal aspects to Waste Chemical Management and Disposal 1. Occupational Health and Safety Legislation 2. Dangerous Goods Legislation 3. Environmental Protection Legislation 4. Water Corporation Legislation

5 1. Occupational Health & Safety Outside the mining and petroleum industries in WA the health and safety of employees is covered by the Occupational Safety and Health Act 1984 and the related Occupational Safety and Health Regulations This legislation places a general duty of care on: employers to provide a safe place and systems of work employees to comply with the legal requirements of their employers A wide variety of government standards, codes of practice, guidelines and support documentation is readily available to both parties: NOHSC publications Worksafe WA

6 1.1 OH&S: Duty of Care Safe Place of Work: Workplace hazards must be identified and controlled (the Hierarchy of Controls principal must be applied) Safe Systems of Work: Adequate training and information must be provided Safety equipment and safe work procedures must be in place and employees must abide by them NOTE: Failure to comply is an offence: penalties range up to $25,000 for employees; $250,000 for employers; and $400,000 for organisations

7 1.2 Workplace Health & Safety Publication Sources NOHSC: ( NOHSC:1015(2001) Storage and Handling of Workplace Dangerous Goods NOHSC:10005 (2005) List of Designated Hazardous Substances Worksafe WA ( Hazardous Substances example register Hazardous Substances example risk assessment

8 2. Dangerous Goods In WA the storage of Dangerous Goods is covered by the Dangerous Goods safety Act 2004 and the associated Dangerous Goods (Storage and Handling of Non-explosives) Regulations The Act and the Regulations are administered by the Dangerous Goods Safety Branch, Resources Safety Division of the Department of Mines and Petroleum. Premises at which dangerous goods are stored are subject to site licensing requirements. Compliance to appropriate Australian Standards constitutes compliance with the Regulations themselves. NOTE: Failure to comply is an offence: penalties can include fines, imprisonment or both

9 2.1 Licensing Requirements Storage of more than minor storage quantities, as defined in the Regulations or a supporting Australian Standard, requires a license. Exceeding the quantity listed below for a particular class of DG at a specific location requires that location to be licensed.

12 2.2 Key Australian Standards AS Safety in Laboratories (Storage of Chemicals) AS The storage and handling of mixed classes of dangerous goods, in packages and intermediate bulk containers AS 1940 The storage and handling of flammable and combustible liquids NOTE: the above are generally applicable, other standards may apply to storage of individual DG Classes

13 3. Environmental Protection In WA legislation governing exposure to pollution for the general community and the environment is covered by The Environmental Protection Act 1986, and the supporting Environmental Protection Regulations General processes for controlling discharges to the environment and for disposal of wastes are specified The disposal of hazardous waste is specifically covered in detail by the Environmental Protection (Controlled Waste) Regulations 2004 NOTE: Failure to comply with the EP Act is an offence: penalties can include fines, imprisonment or both

14 3.1 Controlled Waste Regulations All Controlled Waste: generators require a license movements must be pre-advised to DEP transporters must be licensed by DEP be disposed of in an approved manner at an approved location The contractor is licensed to transport and dispose of controlled waste can advise clients how to meet their legal obligations and manage the government formalities NOTE: Failure to comply is an offence: penalties under these Regulations include modest fines however the EP Act can apply for serious breaches

15 4. Water Corporation Discharge of Industrial Waste to sewer requires a permit this dictates what can be disposed of to sewer guidelines are available at: Trade wastewater must not enter the stormwater drainage system. NOTE: Failure to comply is an offence: penalties can include loss of permit and/or fines however the EP Act can apply for serious breaches

16 Contractor Services: The contractor will: Assist with the manifest Colour code for segregation Pack Remove and dispose

17 Waste Collection: Materials: No change to the inventory without prior written agreement Timing: should be set with regard to internal traffic hazards, must be realistic and adhered to Organisation: paperwork, security and facility access, equipment etc must be in place, on time Support: Relevant staff must be informed and available to assist as required (e.g. internal experts, security, ER team

18 Transport & Disposal Operation Contractor s responsibility. Contractor will provide: Copy of signed Controlled Waste receipts provided to Curtin Certificates of disposal provided on request (no charge)

19 The Curtin Process Curtin s Health & Safety to fund waste disposal in 2007 and 2008 Areas to prepare to request budgets for disposal from 2009 using information gained from 2007/2008. To participate in a Health & Safety funded program electronic Manifests must be forwarded to Curtin s Health & Safety by advertised due dates. Curtin s Health & Safety will co-ordinate a university wide approach on an ongoing basis to assist with cost minimisation.

22 Waste Service Components 1. Containers options to use own and/or Contractor to supply 2. Packing Contractor provide vermiculite FOC 3. Labelling Contractor will provide FOC on the day of collection 4. Collection time-based fee structure 5. Transport & Disposal Contractor responsibility

23 Packing Requirements Bulk products: Some products may lend themselves to bulking into a large capacity drum. Supervision and labelling is critical (Contractor can advise). Individual containers: Fit for purpose and properly labelled is adequate Multiple containers packaged together: Each container fit for purpose and properly labelled Must be compatible Securely wrapped to avoid contact and breakage Leak proof (with absorbent in place for liquids) Copy of inventory on inside and outside of containers

24 Chemical Compatibility Chemicals that can react dangerously if mixed MUST NOT be packed together e.g. acids and alkalis; oxidisers and flammables Chemicals MUST NOT be packed in incompatible packaging materials e.g. oxidisers and combustibles (this applies to both primary and secondary containers)

25 Container Quality Suitability: must be fit for purpose Liquid containers and lids must be in good condition, liquid tight and secure Solids containers must be robust and leakfree Compatible with contents (applies to primary and secondary containers) Fragile containers (eg vials) will require special handling/packing

26 Labelling Containers for Transport Contents Labels: required standard Legible and in good condition Accurately reflect the contents DG class diamond attached to Contractor disposal manifest sticker attached Contractor Colour Coded see following slide

29 MSDS & Other Safety Resources It is a legal requirement that ready access be available to Workplace Health & Safety information for all hazardous chemicals on site Curtin subscribes to the Chem Alert MSDS database system, accessible via the intranet Some locations also use hard copy file stations. Curtin Chemical Risk Assessment Process see following slides

30 Example from Hazardous Substances Register

31 Curtin University : Chemical Risk Assessment The Chemical Risk Assessment Work Sheet is designed to prompt you to think about the risks you face when using chemicals and whether you believe the current controls will adequately protect you. You should not proceed with the use of a product if you believe it is unsafe. You will need to obtain an MSDS for the product to be able to complete the assessment. This can be obtained from Chem Alert or upon request from the supplier. For further information on risk assessments, refer to section 5 of the Health & Safety guide to Making the Workplace Safe The risk assessment work sheet can be found in the Hazardous substances section of the Health & Safety web site.
