2. Hazardous and Biological Waste

Management of hazardous waste in HUS areas


Copyright: Colorbox

Employees working in areas owned by Helse-Bergen should follow hospital guidelines for waste disposal.

In the common waste disposal rooms there are cardboard boxes, inserts, red plastic bags, wires and labels. The cardboard boxes should, as a safety measure, be labelled with the appropriate label prior to use. When they are ¾ full they should be closed and placed in the waste room for collection.



Common waste disposal room: every floor.

Hazardous waste disposal room: ask the contact person for each floor.

The contact person can be contacted if you need more information.

Waste management requirements:

  • Disposal of chemicals and packaging without  hazardous labelling, are treated as standard waste.
  • Other hazardous waste must be handled and packaged in accordance with law and regulation.
  • Empty chemical bottles, solvents containing cytostatics and methanol plastic containers must be declared
  • The waste must be packed safely so that transport damage does not occur. Eg. Use shock absorbing material between glass bottles.
  • Declaration form must be filled out for each item.


Hazardous waste:

Chemicals: Corrosive acids and bases, disinfectants, mercury-containing and 49 cyanide-containing wastes, heavy metals, organic solvents with and without halogen and reactive substances and cytostats.
EE waste: Wastes from electrical and electronic products contain both valuable resources and components with hazardous properties. Examples: Mercury switches, PCB-containing capacitors and circuit boards with brominated flame retardants.
Radioactive waste: Radiation sources used to treat diseases, radiation sources in instruments and analysis tools. Equipment that has been contaminated by radioactive radiation or radioactive substances.




1: Biological waste:

 Cardboard box: For laboratory work and daily use.  These boxes are sorted in 3 categories and placed in the waste rooms. Use red or yellow plastic bags according to instructions.

Here smaller amounts of cytostatics, antibiotics and materials which may be cancerous, mutagens, poisonous, health damaging or damaging to the environment should be discarded. The boxes are frozen to -20°C in the Environmental hall and then transported for combustion at 900-1000°C.

Test tubes/agar plates: Contagious waste such as used agar plates and test tubes which contain blood or tissue fluids. As well disposable equipment and gloves which may be contaminated or have been in contact with organic test material, and 10 litre liquid container from cell lab (containing Virkon). The boxes are frozen to -20°C in the Environmental hall and then transported for combustion at 900-1000°C.

Sharps: Yellow plastic boxes with lids for hypodermic needles, scalpel blades, microscope slides and other glass/sharp objects. These yellow plastic boxes should be purchased by each group. Please note that there can not be liquid exceeding 500ml (max liquid volume for the autoclave). The boxes are then transported for combustion at 450-500°C.


2 Chemical waste:

Red waste box: Dangerous waste should be packaged in its original packaging or some other suitable packaging and labelled with the declaration number.

Clear plastic container: Solvent without halogen, not in its original packaging, should be put in the clear container and labelled with the declaration number.

Blue plastic container: Solvent with halogen, not in its original packaging, should be put in the blue container and labelled with the declaration number.



3 Low radioactive waste:

Discarded objects, biological materials, solutions or substances that contain or have been contaminated with radioactive substances should be collected and thrown in a cardboard box containing a red bag and labelled as radioactive waste.

Sticker for radiation waste

Use the sticker to fill in:

  • Content: i.e. Cell lines in 96-well tray
  • Activity: 3 H Tritsium
  • Content of isotopes: Tritsium – 3H
  • Activity appr.: <0.2 μS
  • Department: NN
  • Date: xx.xx.xx
  • Responsible: NN


Handle empty, hazardous chemical bottles:

Hazardous chemicals bottles that are empty must be declared and the declaration form filled out.

First, check the datasheets for information on how to handle and declare the chemicals.

  • Declaration number and (name of the compound/chemical if not the original bottle) should be written on the bottle. Use a sticker if it the bottle is brown.
  • If the chemicals are not identified on the original bottle, check the data sheet.
  • The declaration form must be filled out. (in Section 5, it is an example of how to fill out a declaration form).
  • The bottle should be placed in an empty red waste box. On the red waste box, the same shape number must be labelled as it is on the bottle. Type the number on a sticker and paste it on the box.
See here for information regarding the declaration forms.
