Laboratory safety in general

Before starting any laboratory experiments, everybody at DBB must read and understand the regulations and instructions:

Laboratory safaty and management at DBB 2019 (1756 Kb)


You will also have to state that you understand and will work accordingly, by signing this document:

Signature for labwork at DBB (12 Kb)

This information is also meant to be used as a reference in the daily work.


Pregnant or breastfeeding

For pregnant and breast feeding employees or students, an individual risk assessment has to be performed, to ensure the working environment is safe. It is therefore important that either the group leader, a work environment representative (skyddsombud) or the Safety Coordinator, Liselotte Antonsson is informed as soon as possible.

Pending the risk assessment, no lab work should be done


Chemical safety in general

  • Chemicals have to be handled and stored safely and according to the regulations.
  • KLARA is a management system for handling chemicals. The KLARA registry gives safety information and safety data sheets from suppliers.
  • In KLARA there is also a tool for Risk Assessments.
  • Liselotte Antonsson is KLARA administrator.



CMR investigation

  • Handling of CMR (carcinogenic, mutagenic and toxic reproduction) chemicals is subject to special rules and require specific routines. Before work starts it is a requirement to carry out a documented investigation whether it is possible to replace a CMR substance with a less hazardous substance.
  • There is more information about this routine in our Lab Safety DBB folder in Stockholm University BOX. BOX can be found at SU/Medarbetare/Stödsystem.
  • Contact Liselotte Antonsson if you want to get access to the folder or have questions regarding these investigations.

Risk assessments

  • According to the Swedish Work Environment Authority all potential hazardous procedures, (using chemicals and/or equipment), need to be risk assessed.
  • Risk assessing planned experiments is the responsibility of each research group leader.
  • Risk assessment can be done by using a tool in KLARA.

Handling of liquid nitrogen

Handling of liquid nitrogen involves several risks for accidents and ill health and it is potentially very hazardous. Only users with sufficient experience and knowledge about risks that can arise from handling liquid nitrogen are allowed to handle it.

There is a liquid nitrogen filling station in Arrhenius lab at floor 2, The station belongs to SU-butiken and access is granted to those who fulfil SU-butikens and DBBs requirements.

See Safety instructions below,  for DBB routines and how to get access.

Users need to have participated in an introduction held by Property Management office. Introductions are held approx. 4 times/year.

The planned introductions  for year 2021 are: 31 March, 17 June, 1 September and 3 November. Contact Björn Röstlund if you want to participate in a sessionåd-stöd/lokaler-service/behörighet-påfyllnad-flytande-kväve-1.544240


Waste management

For laboratory waste, see waste handling in the “Environmental Work” section.

Waste containers are sold by SU-butiken.

Radiation safety

Before you are allowed to work with radioactivity you have to attend a course and pass a test, Radiation safety (in english). This is a compulsory course for all employees who work with open/sealed sources or X-ray.

Contact the local radiation safety contact person at DBB, to find out how to proceed. 

When you have passed this course you will get access to the main isotope lab, and get access to a shared folder in BOX, with more information.

Before starting practical work you also have to have taken part of risk assessments and handling instructions for your planned experiments. The group leader is responsible for this.  is Stockholm Universitys contact person for radiation safety.



Biosafety concern safety for work with biological agents. This includes control of pathogens, toxins and genetically modified microorganisms (GMM). The use is regulated by The Swedish Work Environment Authority (Arbetsmiljöverket).

Depending on the level of risks, the work and facilities in which the work is performed need to adhere to certain standards and may need approval by Arbetsmiljöverket. For GMM there is always a notification or approval needed.

If you have further questions, Jan-Willem de Gier is the contact person at DBB.
