Safety
Biosafety:
1. Would any of your project ideas raise safety issues in terms of:
Researcher Safety:
Our laboratory is certified for Biosafety Level 1 work and Biosafety Level 2 work. Our work fell within the BSL-1 domain, as indicated per Center of Disease Control guidelines. All students working in the laboratory were required to complete the following set of training tutorials, including passing a test at the end.

All materials were used in accordance with local, national, and Yale's Biosafety requriements. Standard lab practices were followed, including secondary containment of chemicals, proper storage of volatiles and flammables, and separation fo acids and bases. Nitrile gloves were worn at all times within the lab. Double nitrile gloving was used when handling ethidium bromide, a toxic chemical and suspected mutagen. A pipet was kept exclusively for ethidium bromide use. We obtained SYBR Safe to stain DNA in August, which is safer than ethidium bromide. Fume hoods were used when handling volatile compounds, concentrated acids and bases, and other reagents. Inhalation and skin contact was avoided. Chemical agents were properly disposed of in designated biohazard waste bins. When UV light was used to visualize gels or GFP, a UV-blocking shield was used. Absolutely no food was allowed in the lab.
E. coli and C. elegan strains used in our experiments were not pathogenic. E. coli were decontaminated with a dilute chlorox bleach solution. Anti-freeze proteins are non toxic, and are even found in some commercial ice-creams! All biological waste was stored in autoclave bags and were autoclaved prior to disposal. Sharps and broken glassware were disposed of according to institutional guidelines. Hazardous liquid waste was clearly labeled, and stored in secondary containment for disposal by the institution.
Public Safety:
We do not anticipate threat to public safety. Organisms that we worked with are all non-pathogenic. They are likely unable to survive outside of the lab environment. Biomaterials were disinfected with chlorox and autoclaved after use. We did not use gloves to touch doors outside of the laboratory to avoid others coming into contact with our chemical and biological agents.
Environment:
The risks of environmental harm were mitigated by following the above protocols. Hands were washed before and after leaving the laboratory.
2. Do any of the new BioBrick parts (or devices) that you made this year raise any safety issues?
Our new biobricks consist of novel and previously well characterized anti-freeze proteins. These are non-toxic proteins, and some antifreeze proteins are even used in food additives. Bacterial strains are non pathogenic.
3. Is there a local biosafety group, committee, or review board at your institution? If yes, what does your local biosafety group think about your project?
Our project was overseen by the Yale Biological Safety Committee and the Office of Environmental Health and Safety (OEHS), as well as the Yale Animal Resource Center. Our project has been approved as consistent with Yale's safety regulations.
4. 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?
All teams should be required to submit a letter of safety approval from relevant safety offices. Physical containment should not be the only safety measure taken by laboratories. One possibility is creating new organisms that proliferate only when exposed to a certain laboratory chemical. Because the lab chemical is not found in nature, proliferation outside of the lab is limited. Lab organisms might contain a "kill-gene", that is inactivated only when a laboratory reagent (rare in nature) is provided.
