Here we present answers to questions from safety forms.

Part 1

Please describe the chassis organism(s) you will be using for this project. If you will be using more than one chassis organism, provide information on each of them:

3. List and describe all new or modified coding regions you will be using in your project. (If you use parts from the 2013 iGEM Distribution without modifying them, you do not need to list those parts.)

4. Do the biological materials used in your lab work pose any of the following risks? Please describe.

a. Risks to the safety and health of team members or others working in the lab?

Laboratory strains of E. coli are not pathogenic, thus they do not pose threat for anyone in the lab.

b. Risks to the safety and health of the general public, if released by design or by accident?

None of the biological materials we are working with this year can pose threat to safety and health of genral public.

c. Risks to the environment, if released by design or by accident?

The only materials possibly hazardous to the environment we are working with are plasmids containing genes coding resistance for antibiotics such as ampicillin, chloramphenicol and kanamycin.

d. Risks to security through malicious misuse by individuals, groups, or countries?

There is no possibility of malicious misuse.

5. If your project moved from a small-scale lab study to become widely used as a commercial/industrial product, what new risks might arise? (Consider the different categories of risks that are listed in parts a-d of the previous question.) Also, what risks might arise if the knowledge you generate or the methods you develop became widely available? (Note: This is meant to be a somewhat open-ended discussion question.)

Our project is not meant for public use in open environment. If our acrylamide sensor became widely used as a commercial product its area of usage would still be laboratories and other closed facilities. None of the biological parts, methods and ideas we developed introduce novelties that can be directly misused and therefore pose a risk to anyone.

6. Does your project include any design features to address safety risks? (For example: kill switches, auxotrophic chassis, etc.) Note that including such features is not mandatory to participate in iGEM, but many groups choose to include them.

Our project includes a kill switch. It is based on two components: MinC protein (which inhibits cell division) and T4 bateriophage derived lysis device. MinC expression will be induced firstly, to reduce the odds of bacteria adapting via negative selection. Expression of the lysis device will be delayed with the application of LuXI/LuxR timer device.

7. What safety training have you received (or plan to receive in the future)? Provide a brief description, and a link to your institution’s safety training requirements, if available.

As all students of University of Warsaw we received standard training in area of hygienic and safe work with special emphasis on matters connected to our area of study.

8. Under what biosafety provisions will / do you work?

We are working accoriding to the guidelines for conducting work with GMO issued by Polish government.

a. Please provide a link to your institution biosafety guidelines.

Our instituion does not have any specific biosafety guidelines. ?

b. Does your institution have an Institutional Biosafety Committee, or an equivalent group? If yes, have you discussed your project with them? Describe any concerns they raised with your project, and any changes you made to your project plan based on their review.

There is no group of this kind at our institution.

c. Does your country have national biosafety regulations or guidelines? If so, please provide a link to these regulations or guidelines if possible.

Yes, we do have such regulations: http://isap.sejm.gov.pl/DetailsServlet?id=WDU20010760811.

d. According to the WHO Biosafety Manual, what is the BioSafety Level rating of your lab? (Check the summary table on page 3, and the fuller description that starts on page 9.) If your lab does not fit neatly into category 1, 2, 3, or 4, please describe its safety features [see 2013.igem.org/Safety for help].

e. What is the Risk Group of your chassis organism(s), as you stated in question 1? If it does not match the BSL rating of your laboratory, please explain what additional safety measures you are taking.

The risk group of organisms is 1.

Part 2

1. Organism name and strain name or number.

Following mammalian cell lines:

• HEK 293
• HeLa
• 143 B
• SH SY5Y

2. Organism Risk Group:

As mammalian cells are not classified as microorganisms, they are not included in the ABSA Risk Group list

3. If you are using this organism as a chassis, write "chassis". If you are using a genetic part from the organism, give the name of the part and a brief description of what it does and why you are using it.

None of the above. See paragraph 8.

4. How did you physically acquire the organism or part?

We’ve obtained the cell lines from Institute of Genetics and Biotechnology.

5. What potential safety/health risks to team members, other people at your institution, or the general public could arise from your use of this organism/part?

None. Mammalian cells that we’re using are unharmful for people and environment.

6. What measures do you intend to take to ensure that your project is safe for team members, other people at your institution, and the general public?

As our work in the cell lab is safe and unharmful to others there is no need to undertake additional safety measurements. What we will be working on in our project is to check the cytotoxity of acrylamide. Our aim is to show how acrylamide may affect different tissues reflected by the cell lines derived from these tissues. We would like to examine how different concentrations of acrylamide may influence the cells and draw a parallel to living organisms.

7. If you are using only a part from the organism, and you believe the part by itself is not dangerous, explain why you believe it is not dangerous.

Question not relevant.

8. Why do you need to use this organism/part? Is there an organism/part from a less dangerous Risk Group that would accomplish the same purpose?

We are using different cell lines to demonstrate cytotoxic effect of acrylamide. As our work with mammalian cells is absolutely safe, there is no need to search for another solutions.

9. Is the organism/part listed under the Australia Group guidelines, or otherwise restricted for transport? If so, how will your team ship this part to iGEM and the Jamborees?

We are not going to ship the cell lines to iGEM. We’ll only present the outcomes on the Jamborees.

10. Please describe the BioSafety Level of the lab in which the team works, or description of safety features of lab (Refer to Basic Safety form, question 8. d.). If you are using organisms with a BSL level greater than you lab, please explain any additional safety precautions you are taking.

In our cell lab we obey all of the safety rules provided. Our supervisor familiarized us with the safety rules that are as follows:

• wearing aprons and gloves while working in the lab
• not drinking or eating in the lab
• decontamination of stocks, and other materials before disposal, using an effective method.
• placing materials to be decontaminated outside the cell lab in a durable, leak proof containers
• using disposable glassware
• carefull management of glassware, especially broken pipettes must be handled carefully
