Purpose

The purpose of this procedure is to ensure that chemicals and gases are disposed of in a way that is safe for everyone who uses NTNU's laboratories and NTNU's surroundings.

Scope and anchoring

Guideline for the handling and use of chemicals and gases is governing this procedure (in Norwegian].

The procedure applies to everyone who disposes chemicals and/or gases from NTNU's premises or areas of authority.

Hospital buildings

The procedure does not include disposal of chemicals and/or gases from hospital buildings. NTNU employees in hospital buildings must follow St. Olav's Hospital's disposal procedures.

NTNU in Gjøvik og Ålesund

NTNU in Gjøvik and Ålesund is not covered by the framework agreement concluded with Børstad. The waste must be declared and disposed of to local actors, with the necessary permits for handling and receiving hazardous waste. Other parts of this procedure must be followed.

Definition

See Guideline for the handling and use of chemicals and gases[in Norwegian].

Responsibility

Employees who generate hazardous waste must

• assess whether the waste should be classified as hazardous according to the requirements of waste regulations.
• make sure that what is disposed of as hazardous waste does not contain explosive, self-igniting or radioactive substances.
• assist the disposer of the waste with all the information necessary for correct sorting and declaration. Safety data sheets/information sheets can be found in NTNU's Chemical index, and can advantageously be attached to the product to be disposed of.
• dispose hazardous waste at least once a year. If the business is shut down, or there is a shutdown for more than 3 months, waste must be disposed of immediately.

Disposer

Disposer is the person who delivers dangerous, infectious and/orradioactive waste fromemployees whogenerated the waste ;to waste recipient. The disposer must ensure that

• the waste is permitted for transport
• the waste is correctly sorted, packed and declared. Containers with waste and outer packaging must be suitable for transport. Containers must be undamaged and any caps must be screwed on. If containers with hazardous waste in solid form are damaged: Use new outer packaging, for example ziplock bags.
• The recipient of radioactive waste is contacted before the waste is possibly sent with Børstad. This is to ensure that Børstad can deliver the waste.
• hazardous waste is handled and disposed of in accordance with this procedure.

The waste recipient must be contacted if you, as the disposer, are in doubt about what is the correct sorting, packaging and declaration.

Procedure for disposal of chemicals and/or gases - for disposers

Declaration and disposal

The following points must be included in the order:

• Orderer's name and department
• Retrieval address
• Contact person who will be present in connection with collection, as well as telephone number
• Number of packages and type of package (e.g. box, pallet, barrel, IBC etc.)
• Return packaging (new packaging to be delivered to the institute)
• Declaration number for waste is entered in order/purchase order
• Desired collection time
• Information about waste substance number, EAL code, ADR hazard class, UN number and packaging group for the most common waste categories can be found in NTNU's table for declaration of hazardous waste.
• If necessary, check section 14 of the safety data sheet for waste that does not fit into any of the categories described in the table above. Safety data sheets can be found in the Chemical index.
• When declaring unidentified chemicals, or if you are in doubt about correct sorting/packaging: Always contact the waste recipient before disposal.

For infectious waste; see own guideline.

1. Log on avfalldeklarering.no and fill in the declaration. If you need a user account, see Access to avfallsdeklarering.no.
2. Order collection of the waste through the ordering system. Register the various declaration numbers in the order that is sent. Alternatively, a copy of the declarations can be attached to the order. This as an extra guarantee that invoicing is done to the correct unit. Enter "Børstad" under "Supplier" and the correct project number.
3. Print out the declarations from avvalsdeclarering.no and hand them to the driver when collecting.

The declarations will have the status "Sent declarations" in avfallsdeklarering.no until they have been checked and possibly corrected by the waste receiver. This is followed by a waiting period of 7 days before they are forwarded to the authorities. The declarations then change their status to "Finished declarations". This is, in addition to the received invoice, your documentation of disposed of hazardous waste.

Disposing of radioactive waste: Børstad can arrange for the transport, but not intermediate storage of radioactive waste . Make an agreement with the company that will receive radioactive waste before you order collection/transport.

Packaging

• To avoid running out of packaging: Order empty packaging at the same time you order collection of hazardous or infectious waste.

Orders must be made via the ordering system.

Note that for each declaration the weight is rounded up to the nearestkg, which will have an impact on the price. Therefore make an assessment of what can safely be declared and disposed of together. One declaration can apply to several parcels (bottles, jugs, etc.). However, all packages must be marked, as described under Packaging and marking.

How to fill in a declaration in avfallsdeklarering.no

See guide from avfallsdeklarering.no.

Here you can find information on how to declare hazardous waste

• NTNU's table for declaring hazardous waste. If you do not find the information you need in this table:
  • See safety data sheet, point 14.
  • Lists with waste substance numbers and EAL codes can be downloaded.
  • Contact the waste receiver if you cannot find the necessary information.

Description of the waste

• Enter waste substance number and EAL code
  • If you start writing in the fields, suggestions for hits will also come up.Example: Search for "inorganic" under "Waste substance number" will give hits on e.g. . "acids, inorganic", waste substance number 7131. A search for "sulfuric acid" under EAL codes will yield hits on e.g. "sulfuric acid and sulphurous acids", EAL code 060101.
• Describe the waste under "Detailed description". Indicate, as far as possible, the chemical's name and concentration. State the pH value and possibly nitrate concentration.
• You can upload file attachments, if you wish. For highly reactive chemicals (waste substance numbers 7122 and 7123) safety data sheets must always be attached. Such chemicals must be declared separately.

Transport classification

• Select "ADR" under "Transport classification"
  • Select the correct hazard labels under "ADR classification" (both main class and possibly additional class ).
  • Under "ADR class" the main class is selected.
• Fill in the UN number, packaging group and any additional information.

The information for filling in the fields under "Transport classification" can be found via aids, as described above. Note that the UN number can be denoted "FN number".

Waste reception and transporter

• "Select waste reception": Select «Farlig avfall - Sutterø - Børstad Transport AS»
• " Transporter": Select "Waste reception".

Summary and Submission

• Click «Sign and send declaration» when the declaration has been completed. By signing, you confirm that the content is in accordance with the declaration. Also remember to write the declaration number on the packaging on the standard sticky note (orange and white) where all the fields are filled in.<
• Possibly missing items in the declaration will be listed in red to the right of the screen.
• Note that ordering collection must be done through the ordering system.

If there is any doubt about the correct declaration, this must be clarified with the waste receiver.

Access to avfallsdeklarering.no

To be able to declare hazardous waste and radioactive waste through avfallsdeklarering.noyou need a user account. Contact:

• Espen Fjærvik (employees at the NV Faculty)
• Ingvild Hammer (employees at the MH Faculty)
• Bjørn Ola Dragset (other employees)

Collection / transport

• Trondheim: Børstad Transport AS has established a waste collection route. You can order an additional collection at an additional cost. Orders are sent to Børstadthrough the ordering system.
• Ålesund and Gjøvik: Contact a local operator, with the necessary permits.

Order collection throughthe ordering system. If your device have a separate agreement with the waste receiver regarding regular collection, you do not need to order.

Sorting

• None of the waste categories must contain radioactive, explosive or self-igniting chemicals. If you are unsure whether the chemicals may have such properties, the waste recipient must be contacted before disposal! This is how you identify explosive, self-igniting and highly reactive chemicals.
• Acids and bases are packed in separate boxes.
• Solid and liquid chemicals are packed in separate boxes.
• Highly reactive chemicals must be sorted and packed separately (waste number 7122 and 7123). Attach data sheet. How to identify highly reactive chemicals using safety data sheets.
• When disposing of gas(es)
  • remaining inventory is returned to the supplier.
  • NTNU Eiendom must be informed about the disposal.
  • user equipment must be dismantled, possibly stored and disposed of in a responsible manner.
  • The room card database must be updated
  • Signage on the door/access must be updated
  • Any gas detection/alarm monitoring must be disconnected, this is carried out in collaboration with NTNU Eiendom.

Packaging and labeling

• The chemicals are supplied as far as possible in the original containers, if they are still suitable for transport and storage.
• Chemical waste must be marked on the outer packaging with the declaration number, UN - number and danger labels. Use standard sticky note (orange and white) where all fields are filled in. Also glue on clearly visible ADR marks where necessary.
• The marking must be easily visible. Use waterproof marker and pre-printed labels and danger labels (stickers). This can be ordered from the waste receiver. Do not write directly on the outer packaging, as this is reused to some extent!
• Always use absorbent when packing chemicals together. Fill a layer of vermiculite, or equivalent, in the bottom of the box. Vermiculite is approved for both organic and inorganic chemicals. Approved packaging is sufficient for other types of waste than chemicals.
• Pack the waste so that the risk of breakage is reduced. Always use shock-absorbing material between glass containers.
• In case of breakage, the use of plastic boxes provides better safety against spillage. For liquid waste: Use plastic cans intended for the transport of chemical waste.
• Use a membrane screw cap if there is a risk of gas generation from liquid waste. Any gas will then escape and reduce the risk of the container exploding.
• Outer cardboard packaging used for the transport of chemicals must be UN approved . The packaging must then be marked with UN, followed by a number and letter combination that describes what the packaging has been tested/approved for. Packaging that is approved for use in the transport of dangerous goods is marked with the packaging group to which it is adapted. Standard cardboard boxes used for the delivery of chemicals to NTNU can normally be used as outer packaging.

Waste that must not be mixed together with chemical waste:

Infectious waste, radioactive waste, explosive and/or self-igniting chemicals must not be mixed with other chemical waste.

See especially points 2 and 14 of the safety data sheet for information on whether a chemical is radioactive. How to identify explosive and self-igniting chemicals is described below.<

How to identify explosive, self-igniting and highly reactive chemicals

The waste receiver doesnotaccept explosive and self-igniting chemicals. It is very important that explosive and self-igniting chemicals are identified and not disposed of together with other chemical waste due to risk of fire/explosion.

Act with particular care when handling explosive and self-igniting chemicals! Do not unscrew the lid. Avoid shocks and vibrations.

Employees at the NV faculty can contact the HSE advisor Espen Fjærvikwhen disposing explosive and self-igniting chemicals. Employees at other faculties can contact HSE adviser Arve Johansen, HSE Section.

Identifying explosive and self-igniting chemicals using safety data sheets

Safe identification of explosive and self-igniting chemicals requires a thorough review of points 2, 10, 13 and 14 in the safety data sheet of the product to be disposed of (see below). Note that older safety data sheets may have different numbering than indicated here:

Most important hazards (Section 2)

Explosive substances are indicated with the danger symbol "explosive" only when this is assessed as a primary hazard. Self-igniting substances can have different danger symbols, but are mainly marked as "flammable ".

It is not possible to identify all explosive and self-igniting substances based solely on the danger symbol specified under point 2. Substances can be explosive or self-igniting/oxidizing even if the primary danger is linked to toxicity/ environmental harm.

Example: Dinitrophenol (moistened), CAS 51 ‐ 28 ‐ 5:

• Danger symbols under point 2 are "Toxic" and "Environmentally harmful", but dinitrophenol must still be classified as explosive. Dinitrophenol is identified as explosive by finding hazard class 4.1 in point 14 of the safety data sheet. Then look at the given UN number; UN number 1320 is stated. UN number 1320 is then checked against the most commonly used UN numbers for explosive substances, see list of relevant UN numbers below (Danger class 4.1 ).

Stability and reactivity (Section 10)

Contact the waste recipient if point 10 says anything about the risk of explosion or spontaneous combustion.

Information on waste disposal (Section 13)

This section contains general information about the disposal of the product.

Information on transport (point 14)

UN number, hazard class, packaging group and requirements for labeling with a hazard label. Two classes may be stated under the item "Danger label"; main class and additional class (for example 4.1 + 6.1 ).

Danger class 1 (explosive substances): The waste recipient cannot accept products marked with danger class 1. The same applies to substances that have danger class 1 as an additional class .<

Danger class 4.1 (self-reactive substances, desensitized explosives):< All substances with danger class 4.1 as the main class must be checked against the list with UN numbers associated with explosive substances.

This is how you do it:

• Check whether hazard class 4.1 is stated.<
• Compare the given UN ‐ number with these UN numbers:

UN 1310, 1320, 1321, 1322, 1336, 1337, 1344, 1347, 1348, 1349, 1354, 1355, 1356, 1357, 1517, 1571, 2555, 2556, 2557, 2852 , 2907, 3317, 3319, 3344, 3364, 3365, 3366, 3367, 3368, 3369, 3370, 3376, 3380 and 3474.

These numbers are the most commonly used UN numbers for explosive substances. Source: ADR/RID 2023, 2.2. 41.1.18.

Waste recipient cannot accept products with these UN numbers:

Danger class 4.2 (self-igniting substances): The waste receiver cannot accept products marked with this danger class.

Danger class 5.2 (organic peroxides): If the substance has additional class 1, the substance is explosive and cannot be accepted by the waste recipient.

If there is any doubt as to whether the substance is explosive or self-igniting: Contact the waste recipient.

Nitro compounds, peroxides and peroxide-forming chemicals

Everyone who handles such products must pay particular attention to them.

All nitro compounds must be carefully examined for potential explosion hazards. Many peroxide compounds are highly reactive and can be explosive. Examples: Nitrophenol compounds, among others CAS No. 96 ‐ 91 ‐ 3, 489 ‐ 98 ‐ 5, 88 ‐ 89 ‐ 1 and 88 ‐ 88 ‐ 0.

The risk of explosion can be stated in the safety data sheet under point 2 "most important hazards" and point 10 "stability and reactivity". Organic peroxides have danger class 5.2 (see above ).

Organic solvents and other chemicals, including diethyl ether, can form peroxides and become explosive during storage. It is therefore very important to have control over the storage time when storing such products. Organic solvents and other chemicals that can form peroxides are divided into three risk groups:

Group A: Chemicals that can produce dangerous levels of peroxides after prolonged storage.

Group B: Chemicals where dangerous levels can be formed by concentration as a result of evaporation.

Group C: Chemicals where peroxide formation can start a heat-generating polymerization reaction.

Substances from groups A and B must be handled with great care. This particularly applies to peroxide-forming chemicals older than a year, or with an unknown history. If in doubt: Do not open the container, but deliver it directly for disposal.

This guideline for risk and chemical waste isnot comprehensivefor all measures that may be necessary in connection with peroxide-forming chemicals. Information on the risks of chemicals that can form peroxides, a list of chemicals in the above risk groups and recommendations for storage and control can be found here:

• The Danish Emergency Management Agency
• University of Bergen

Identifying highly reactive chemicals using safety data sheets

Highly reactive chemicals must be sorted separately and not packaged together with, or included in, other types of waste. Any potentially explosive and self-igniting substances must first be identified. To identify a product as highly reactive, points 2, 10 and 14 of the product's safety data sheet must be checked.

Most important hazards (point 2): Danger symbol "Oxidizing" represents highly reactive substances.

Stability and reactivity (point 10): The substance is classified as "strongly reactive" if strong reactivity is stated here. If there is any doubt, the substance must be treated as "highly reactive". Contact the waste receiver if you need help.

Information about transport (point 14):

Danger class 4.1 (Easily flammable and combustible)

Many substances in this class can be highly reactive or explosive. Check the UN number against the list of UN numbers above. If in doubt: Contact the waste recipient.

Danger class 4.2 (Self-igniting substances)

Waste recipient cannot accept products marked with this hazard class.

Danger class 4.3 (Evolution of flammable gas in contact with water)

All substances with this hazard class are highly reactive and must be labeled with waste substance number 7122.

Danger class 5.1 (Oxidizing)

All substances with this hazard class are highly reactive and must be labeled with waste substance number 7122. This also applies to all substances with 5.1 as an additional class. Safety data sheets must always be attached when disposing of products with waste substance number 7122.

Danger class 5.2 (Organic peroxides)

All substances with this hazard class are highly reactive substances and are labeled with waste substance number 7123. Safety data sheets must always be attached when disposing of products with waste substance number 7123.

Danger class 6.1 (Toxic substances)

Check carefully what is written under point 10 about "stability and reactivity" in the safety data sheet if the product is marked with this hazard class. If strong reactivity is stated: Contact the waste recipient.

Danger class 8 (Corrosive)

Substances with hazard class 8 and additional class 5.1 (oxidizing) are highly reactive.

Mixing of different chemicals

Mixtures of two or more chemicals can be classified in a "nos position" according to ADR/RID 2023. If you e.g. must classify a mixture of UN1114 Waste Benzene, hazard class 3, packaging group II and UN1307 Waste Xylenes, hazard class 3 and packaging group III, the following classification can be used: "UN1993 Waste flammable liquid nos". (Benzene/Xylenes), hazard class 3, packaging group II.

Table 2.1.3.10 inADR/RID 2023is used to determine the hazard class and packaging group of the mixture. An overview of the various nos positions can be found in section 2.2.X.3, where X refers to the various classes listed in chapter 2.2. See p. 135 for an overview.

If the chemical to be classified is a waste with a composition that is not completely known, then the packaging group and UN number can be based on the sender's knowledge of the substance. If it is possible to demonstrate that the properties of the substance do not fall under packaging group I, then the substance can be classified in the most appropriate nos position in packaging group II.

Dilution of chemical waste

Chemical waste cannot be diluted, or mixed with other types of waste, with the aim of reducing the concentration of hazardous substances, cf. the framework directive for waste (EU)2008/98/EC, Article 7, paragraph 4.
