1 Waste Management System. Procedure for the storage, collection and disposal of used chemicals, solvents and other hazardous substances Corporate Procedure: CP-WMS 011 Authorised by: Charlotte Winnert Issue number: One Date of issue: 15 th April 2011 Purpose To define the University of Sheffield s legal obligations and procedures associated with the storage, collection and disposal of used chemicals, solvents and other hazardous substances. Scope This procedure applies to waste chemicals, solvents and other hazardous substances generated by the University, the Medical School and the Dental School. Legal framework Environmental Protection Act 1990 Control of Pollution (Amendment) Act 1989 Controlled Waste Regulations SI 1992/588 Duty of Care Regulations SI 1991/2839 Landfill Regulations SI 2002/1559 Hazardous Waste Regulations SI 2005/894 Carriage of Dangerous Goods Regulations SI 2009/1348 Waste Management Licensing Regulations SI 1994/1056 Responsibilities Department and employees responsible for identifying materials that need to be disposed of as chemical and solvent waste, and storing materials safely prior to collection by Safety Services. Portering Services responsible for making periodic collections of waste from departments and transferring it to Safety Services immediately prior to packing and transport for disposal. Porters only work under the direction of Safety Services Safety Services responsible for organising the collection and disposal of waste chemicals, solvents and other hazardous substances from departments. Chemistry Main Stores - responsible for storage, collection and disposal of used chemicals, solvents and other hazardous substances generated by the Department of Chemistry and the Department of Physics.

2 Energy and Environment Team responsible for ensuring legal compliance and compliance with this procedure through regular audits at an organisational level. Definitions Duty of Care All waste is subject to a Duty of Care. The Duty of Care applies to anyone who produces, imports, carries, keeps, treats or disposes of controlled waste. In particular, waste holders have a duty a) to take steps to prevent offences involving waste; and to b) prevent other people from disposing, treating or storing the waste without a licence, in a manner likely to cause pollution or harm to health or breaching conditions of their licence. There are also particular requirements placed on those storing and transferring waste. Storage of waste To comply with the Duty of Care Regulations the University must ensure that all waste is stored in such away as to prevent escape or leakage whilst on site, in transit or in storage. The University must act to keep stored waste safe against: 1. corrosion or wear of waste containers; 2. accidental spilling or leaking or inadvertent leaching from waste unprotected from rainfall; 3. accident or weather breaking contained waste open and allowing it to escape; 4. waste blowing away or falling while stored or transported; and 5. scavenging of waste by vandals, thieves, children, trespassers or animals. Transfer notes and written descriptions The Duty of Care regulations require written descriptions and transfer notes to be completed when waste is transferred between two parties. On the transfer of controlled waste, both the University and the waste carrier must complete and sign a transfer note, which must be kept for two years. The transfer note must contain the information given below. 1. the identification of the waste; and its quantity; whether it is loose or in a container; if it is in a container, the type of container; place and time of transfer; the appropriate six-figure code from the European Waste Catalogue. 2. the name and address of the transferor and transferee; 3. whether the transferor is the producer or importer of the waste; 4. if the transferee is authorised for transport purposes, which of those purposes apply; 5. the category of authorised person that the transferee (and the transferor, where applicable) comes under, or which exemption applies and why they are exempt.

3 The description of the waste should mention any special problems and should include the type of premises or business from which the waste comes, the name of the substances, the process that produced the waste, and chemical and physical analysis. Hazardous waste and consignment notes Where hazardous waste is being produced it is a legal requirement for the premises to be notified to the Environment Agency. Upon registration the premises will be issued with a sixfigure premises code, which must be renewed every year. Holders of hazardous waste are also subject to the Duty of Care Regulations and a system of consignment notes. However, the consignment notes fulfil the Duty of Care requirement for a written description to accompany the transfer of waste. Consequently a consignment note is the only document that needs to be completed when hazardous waste is collected for disposal. The consignment note may be completed by the transporter of the waste, however the University must ensure that the waste has been consigned correctly. A consignment note is divided into 5 sections, parts A to E. The University must complete section A of the note which should contain the following information: 1. consignment note code; 2. the address of where the waste was removed from; 3. the Premises Code; 4. details of where the waste will be taken to; and 5. the details of the waste producer if different from 2. The University should also complete section B of the note which should contain the following information: 1. the process giving rise to the waste(s); 2. the SIC for the process giving rise to the waste; 3. a written description of the waste including: the appropriate six-figure code from the European Waste Catalogue; quantity (kg); the chemical/biological components of the waste and their concentrations; the physical form of the waste (i.e. gas, liquid, solid, powder, sludge or mixed); the hazard code(s); the container type, number and size; the UN identification number(s); proper shipping name(s), UN Class(es); packing group(s); and details of any special handling requirements. Section C is completed by the waste carrier. This should include the following: 1. carrier name and address; 2. carrier registration number or details of exemption; 3. vehicle registration number (or mode of transport if not road); and 4. the carrier must also sign and date the consignment note.

4 Section D is completed and signed by the University. By signing Part D the consignor is certifying that: all of Parts A, B and C are correct; the carrier is registered or exempt; the carrier was advised of any precautionary measures regarding the collection; all of the waste is packaged and labelled correctly and the carrier has been advised of any special handling requirements Part E is completed by the consignee. The consignee should complete section E and verify that the wastes listed in Part B match the wastes received. The consignee must provide a return to the University to confirm that the waste has reached its final destination. This can either be a copy of the completed consignment note or a copy of the quarterly returns (which waste managers must produce for the Environment Agency). Three copies of the consignment note should be completed one for the consignor i.e. the University, one for the carrier and one for consignee. Consignment notes and returns must be kept for three years. To ensure that consignors provide hazardous waste returns, the University must also keep a Register of Hazardous Waste Consignment. 06 Wastes from Inorganic Chemical Processes EWC coding for chemical waste waste hydraulic oils * hydraulic oils, containing PCBs * chlorinated emulsions * non-chlorinated emulsions * mineral-based chlorinated hydraulic oils * mineral-based non-chlorinated hydraulic oils * synthetic hydraulic oils * readily biodegradable hydraulic oils * other hydraulic oils wastes of liquid fuels * fuel oil and diesel * petrol * other fuels (including mixtures) waste organic solvents, refrigerants and foam/aerosol propellants * chlorofluorocarbons, HCFC, HFC * other halogenated solvents and solvent mixtures * other solvents and solvent mixtures * sludges or solid wastes containing halogenated solvents * sludges or solid wastes containing other solvents packaging * Packaging containing residues of or contaminated by dangerous substances absorbents, filter materials, wiping cloths and protective clothing * absorbents, filter materials, wiping cloths and protective clothing contaminated by dangerous substances Page 4 of 9

The University bulks up solvent and oil waste using the following categories; halogenated solvents, non-halogenated solvents and oils. The table below gives some examples. Halogenated solvents Hon-halogenated solvents Oils* Chloroform Trichloroethylene Ethylene chloride 1, 2 Dibromoethane Carbon Tetrochloride Genc1ene Acetone Alcohols (eg Iso propyl alcohols; ethan diol; absolute (ethyl) alcohol; methanol; n-propanol; n-butanol; 2-Butoxy-ethanol) Amyl acetate Benzene Butyl acetate Cyclohexane De Solve 8090 Dibutyl phthalate Dioxan Ethers (eg diethylether) Ethyl acetate Ethyl cinnamate Ketones (eg diethyl ketone; Ethyl methyl ketone) Paraffin Petroleum spirit Propylene oxide Tributyl citrate Toluene Tupentine Page 5 of 9 Mixed Lubricant Oils Oils Heating Fuels * Note that specific arrangements must be made for PCB containing oils. They must not be mixed with other oils.

6 Procedure 1. Bulking up and storage 1.1 The employee generating the chemical / solvent waste is responsible for identifying the correct disposal route. Solvents and oils must be disposed of using the bulking up collection and appropriate labelling system. Hazardous chemicals and other materials must be stored separately. 1.2 Solvents must be kept in separate categories according to type - see table on page five. Each drum must be labelled with its group letter or material type and an appropriate hazard transit label- i.e. halogenated for group X and non-halogenated for other groups. 1.3 If using the corporate disposal system waste solvents containing both halogenated and non-halogenated solvents, it must be disposed of as a halogenated solvent. 1.4 Waste oils containing PCBs must not be mixed with other oil waste: they must be clearly labelled, stored and disposed of separately. 1.5 If using the corporate disposal system, halogenated materials and oils must go into 20 litre drums and non-halogenated in 25 litre drums. Waste solvents must be stored and transported in metal containers that are in good condition. Alternatively, oils only may be disposed of in 25L plastic drums. If containers (drums or Winchesters) are re-used all traces of previous labelling must be removed or obliterated. 1.6 Aqueous phases must be decanted whenever possible and contents of the drums must be as near to a neutral ph as possible. Where a potential corrosion problem is unavoidable, the waste must be decanted into the drum on the morning of collection 1.7 Reactive chemicals must not be mixed and must be kept separately. 1.8 Departments must develop and document local procedures for the storage of chemicals and solvents prior to collection by Safety Services or specialist waste management contractor 1.9 Chemicals must not be stored in solvent stores Waste solvent containers must be inspected on a regular basis to ensure that they are in good condition Waste chemical and solvents must be stored in line with the Duty of Care Regulations (see page two) prior to collection. It must be stored safely and securely. If stored outside they must be bunded and protected from the weather Waste solvents and waste chemicals must not be stored for more than 12 months The following warning signs must be displayed on waste solvent store doors Yellow triangle EX sign Highly Flammable No Smoking 1.14 There must be a spill kit in all solvent stores.

Solvents are collected and disposed of more regularly than chemicals, but in both cases collections with a specialist contractor are only arranged when a viable load has been accumulated. 2.2 Departments must notify Safety Services that they have chemicals for disposal as they are generated and provide the following information for each chemical 1. The name of the chemical, 2. The quantity, 3. The nature of the container, and 4. The hazardous properties. 2.3 When there is sufficient material across the organisation to justify a collection of waste chemicals and/or solvents, Safety Services will organise a collection with a specialist contractor. Departments are given approximately three weeks notice that a collection of been organised and may use the first few days to notify Safety Services of any additional chemicals and any solvents that require collection and disposal. No additions to the chemical list can be accepted later than 10 days before the collection. Solvents must be notified no later than 3 days before the collection. 3. Corporate disposal system - collections 3.1 Based on the requests received, Safety Services devise a collection rounds to collect chemicals and solvents from departments. Collections are either made by the waste contractor or Portering Services, both of whom must be supervised by a member of Safety Services. 3.2 Vans used by Portering Services to collect waste chemicals and solvents from departments must have cabs that are separate from the load area. 3.3 Departments are allocated a collection time; a departmental representative must be present to sign for the collection so that if there is a problem in transit, it can be traced back to the department concerned. 3.4 Solvent drums collected from departments are allocated a unique number. This is recorded, along with the category of solvent in a triplicate book. A copy of the receipt is signed by a represented and retained by the department. 3.5 Drums that are not labelled or are in a suspect condition will not be collected, neither will those which are over-filled, contaminated on the outside or with lids which do not fit properly. 3.6 Once collected the waste chemicals and solvents are taken to Safety Services to be listed, segregated and packed in line with the Carriage of Dangerous Goods by the contractor. 4. Chemistry collections 4.1 The waste contractor is contacted when Chemistry have sufficient material to justify a collection of waste chemicals and/or solvents. The waste contractor will catalogue the materials for collection and provide a quotation before any collection is organised. Page 7 of 9

8 4.2 On the day of collection the waste chemicals and solvents are listed, segregated and packed in line with the Carriage of Dangerous Goods by the contractor. 5. Transfer of waste 5.1 Waste can only be handed to an authorised person or to persons authorised for transport. Before transferring to a waste carrier for the first time copies of their carrier licence must be obtained and reviewed the document annually. 5.2 All premises that are producing hazardous waste will be notified to the Environment Agency annually by the Energy and Environment Team. 5.3 All waste transferred from University premises by a waste carrier must be accompanied either by a waste consignment note (see pages two to four for further information). 5.4 Waste consignment notes can be completed by the waste carrier, however those overseeing the collection of waste must check the documentation to ensure the waste has been consigned correctly. 5.5 Copies of waste consignment notes must be kept for three years. A Register of Hazardous Waste Consignment must be maintained to ensure that consignors provide hazardous waste returns. 5.6 In addition to ensuring that waste is only transported by licensed carriers, the University is responsible for ensuring that waste generated by the organisation is disposed of legally. The licences of any waste contractors and sub contractors used for the disposal of waste must be periodically checked to establish that they are working within the restrictions of their licences / permits or exemptions. 5.7 The Energy and Environment Team will periodically audit waste managers and their sites to ensure that the University s waste is not being treated illegally. 6. Spills 6.1 Spills must be cleared up immediately. 6.2 Spill kits or absorbents must kept within close proximity of storage areas. Used spill kits/absorbents must be disposed of a hazardous waste and must not be exposed to any potential sources of ignition. 6.3 Spills must only be dealt with by a trained member of staff. 6.4 All spills, incidents and near misses involving chemical and solvent waste should be reported to an appropriate manager and Accident/Dangerous Occurrence form should be completed immediately. 7. Training 7.1 All new workers will be given a Department Induction where the segregation and disposal of solvent and chemical waste will be covered in addition to other training topics. Departments will be responsible for keeping induction records. Page 8 of 9

9 7.2 Solvent store operatives must attend general fire training, which must be renewed on annual basis; and solvent store training which must be renewed every three years. 8. Audit 8.1 The procedures used for identifying and segregating biological waste will be monitored and evaluated on a regular basis. Waste audits will be managed by the Energy and Environment Team and undertaken annually. Feedback will be given to departments and corrective actions will be completed within agreed time scales.
