Safe waste management and waste declaration of hazardous chemicals
Safe waste management and waste declaration of hazardous chemicals

Waste management and waste declaration of hazardous chemicals require more than just sorting at source – they require careful planning, proper handling and clear documentation. Here we have gathered the basics you need to know about the safe handling and declaration of hazardous waste.
Why safe handling of chemical waste is important
Chemical waste is not like other waste. It may contain hazardous substances that are flammable, corrosive, toxic, reactive and/or harmful to the environment. Many accidents occur after chemicals have been used, when they are stored or disposed of incorrectly.
A thorough risk assessment should always form the basis and include hazards related to storage, transport, interim storage and disposal. Such risk management is an important part of the organisation’s health, safety and environment (HSE) work.
Classification and labelling of waste
It is important that all classified chemical waste is labelled correctly before it is stored or sent to a receiving facility. This includes, among other things:
- Identification of the type of substance (e.g. corrosive, flammable or toxic)
- Use of appropriate packaging that can withstand the contents
- Clear labelling with contents, date, responsible person and hazard pictograms
- Separation of incompatible substances (e.g. acids and bases)
Waste declaration
In Norway, waste declaration is required by law under the Waste Regulations. Waste declaration is a process in which companies report which types of hazardous waste they produce and in what quantities. The purpose is to ensure traceability and proper handling from the business to final treatment.
All companies with hazardous chemical waste must deliver it to an approved reception facility and complete a waste declaration form. The declaration itself must take place via avfallsdeklarering.no and must be completed before the waste is sent to reception. The form will typically contain:
- Waste identification number (UN number) and EAL code
- Chemical content and properties
- Quantity and packaging
- Contact person and carrier
Roles, responsibilities and training
It must be clearly defined who is responsible within the organisation. This will often be an HSE manager or subject specialist with overall responsibility for chemical handling and waste declaration.
Everyone who handles hazardous waste must have the necessary training in chemical safety, procedures and emergency preparedness. This should form part of the organisation’s systematic HSE work.
Environmental impact
Chemical waste is not only a workplace risk; it can also have a significant impact on the environment. Improper handling can lead to contamination of soil, water and air, and create long-term environmental consequences.
Checklist: Safe waste management and waste declaration
Make sure you can tick off these points. Then you are well on your way to ensuring safe and efficient waste management:
- Use appropriate packaging (e.g. sealed, labelled and compatible with the chemical)
- Clear labelling of chemical waste
- Ensure correct interim storage of chemicals
- Complete waste declaration before delivery
- Establish fixed routines for emptying and handling
- Carry out regular risk assessments
- Provide employees with adequate training
- Document and track your waste via avfallsdeklarering.no
- Ensure good ventilation and containment in the waste area
- Have the latest version of the safety data sheet (SDS) and chemical information available
- Have emergency preparedness and protective equipment available
Safe handling and correct waste declaration of hazardous chemicals require planning, good procedures and clear documentation. When this is an integrated part of HSE work, the risk of accidents is reduced and the organisation ensures both compliance with regulations and responsibility for people and the environment.
