Biological Safety

TUDelft safety labcoat.png

Safety considerations are of great importance when working in a biological lab, and as an iGEM team working with biological material we took the necessary safety precautions very seriously.

Biosafety regulations in The Netherlands

In The Netherlands the Ministry of Housing, Spatial Planning and the Environment (VROM) is responsible for the regulations that protect the environment and human health during activities involving genetically modified organisms (GMOs) and is tasked with developing policy and regulations. Many of the implemented regulations concerning GMOs have been taken over from the EU legislation.

At the Kluyver laboratory for Biotechnology, according to what is stated by law, we have a biological safety officer, Dr. L.A. (Lesley) Robertson. The biological safety officer is in charge of day-to-day aspects of institutional biosafety and activities involving GMOs. She must monitor and ensure that all activities involving GMOs are executed in full conformity with Dutch legislation and regulations. An interview was done with Dr. Robertson which gives a clear insight into all the regulations at our laboratory – those regulated by law and those implemented by Dr. Robertson herself.


Prior to working with GMOs in the Netherlands you must obtain a ‘GMO permit’. The type of permit may vary, and the permit needed for iGEM was that of ‘Contained use’. This means that all activities involving GMOs are carried out in a confined area such as a laboratory and that there are no transboundary movements of the genetically modified materials.

Various degrees of containment are recognized, depending on the biosafety level needed for the genetically modified organism. The degree of containment is expressed as a level, ranging between ML1 to ML4, and each level required different safety precautions. Luckily, the organisms we worked with (Escherichia coli and Pseudomonas putida) were both level ML1 – the most harmless of GMOs. More information on how these levels are determined can be found in our Biosafety video in which we interviewed our biological safety officer.

At the Kuyver Laboratory for Biotechnology a permit to be allowed to work with GMOs is already present. To get permission for our experiments we had to supply a detailed research proposal to Dr. Robertson containing information on what strains and vectors we were going to use, which genetic modification we were going to make and which cultivation methods were going to be used. Only after approval of the research proposal could we start with our labwork - luckily she approved, and no changes had to be made. Because we are working under the general permit of the university we are also required to supply an end-report with what activities were performed and what the exact results were.

With knowledge comes responsibility

It is of great importance that everybody knows about the risks in a biological laboratory and can act accordingly and responsibly. This is why at our laboratory a number of tests have to be taken before you are allowed to work in the lab (unsupervised). The first of these is the Biosafety test: each individual is tested on their knowledge of the "Kluyver Biotechnology Survival Guide". This guide contains all information on personal safety, protective clothing, ML-1 regulations, what to do in case of a fire, the use of chemicals and chemical waste. By showing a number of photographs with 'wrong behavior' and asking the individual to identify what is wrong and why it is wrong an awareness is created amongst the new lab residence that will hopefully prevent them from making mistakes in the lab.

Another awareness-test is the hand-wash test devised by Dr. Robertson herself to make people aware of what they are carrying home on their hands after a day in lab (and not washing your hands).

We believe that such tests are very useful, and will create the right kind of mind-set required for each iGEM member to responsibly work in a biological lab. This is why we think it should be compulsory for each new iGEM member to take such a test and we are working on a quiz to perhaps use for future iGEM teams as well.

The picture on the right is a representation of the other photo's also showed in the biosafety test. We dare you to find the 14 mistakes... Think you found all of them? Click on the image to see the mistakes.

Project-specific safety questions

When considering the safety of us, the researcher, while working on our iGEM project there was one specific point: for the characterization of our BioBricks alkanes and alkanols were necessary. These materials are flammable, and therefor must be stored separately in a fireproof cabinet and must be handled with care in a flow cabinet.

Furthermore we also thought about the public safety as well as the environmental safety of our project - we chose to use E.coli K12 as our host organism, which cannot survive outside of the laboratory and therefore does not pose a threat to the public or the environment. At this point our system can therefor not be used for the intentioned goal, the removal of hazardous/polluting oil in the environment, but hopefully more research will be done into this system in the future that will enable its safe use.

Do any of the new BioBrick parts (or devices) that you made this year raise any safety issues?

We do not infringe the rules with our new made BioBrick parts and our BioBricks do not raise any safety issues.

Do you have any other ideas how to deal with safety issues that could be useful for future iGEM competitions? How could parts, devices and systems be made even safer through biosafety engineering?

We think it should be compulsory for each new iGEM member to take a safety test. For our own team we are working on a quiz that perhaps can be used for future iGEM teams as well.

Biosafety in the Lab

In our Department at the TU Delft, the Department of Biotechnology, there is a Biological Safety Officer (BSO) who is responsible for the safety in the labs. In the Netherlands there is a very strict regulation about biosafety and working with genetically modified organisms. Our BSO, Lesley Robertson, always knows what biological material is being used, where and by whom. So, no better person to interview to get to know everything about biosafety!
