Biosafety Provisions
Institutional Regulations
Our project safety procedures are governed by the general regulations of the University regarding the proper standard rules and safety guidelines for laboratory practices.
Teaching and research laboratories in the university are specially regulated accordingly to the dependence they belong to. In our case, the Faculty of Sciences Department of Biological Sciences and Department of Physics.
The specific guidelines for the laboratory work at the Department of Biological Sciences are available online (in Spanish only) [http://micro.uniandes.edu.co/MICUA_/Docencia_files/Reglamento%20DCB%202010.pdf Biosafety Guidelines].
Our main workspaces are the [http://lamfu.uniandes.edu.co/HOME/Home.html LAMFU] and the [http://biofisica.uniandes.edu.co/ Biophysics] facilities, BSL2 research laboratories, but also we occasionally work on several BSL1 teaching laboratories (Department of Biological Sciences).
Institutional Biosafety Committees
There is the Parietal Committee for Occupational Health (COPASO), regulated by the Colombian Constitution (Resolution Number 2013, Year 1989). The information regarding the functions and regulations of the COPASO committee is available [http://tramites.minproteccionsocial.gov.co/tramitesservicios/copaso/copaso.aspx online] (Spanish only).
There is also the [http://investigaciones.uniandes.edu.co/index.php?option=com_content&task=blogcategory&id=56&Itemid=65 Bioethical Committee] of the Faculty of Sciences, to whom we have presented our project proposal. Although we are still waiting for a response from the committee, our research methods and safety precautions are well within the regulations of the Committee.
Biosafety Training & Work Precautions
All team members were required to attend safety training focused on:
• General biosafety principles.
• The proper use of containment equipment (Biological safety (laminar flow) cabinets and delimited working space when required) as well as personal protective equipment (PPE) (White coat and gloves).
• Risk assessment of experiments involving: Recombinant DNA, ethidium bromide, other biohazardous materials.
• Proper Biological waste disposal.
Our main concern was to work with the appropriate safety guidelines for working in both research and teaching laboratories (BL1-BL2) in order to minimize exposure to hazardous agents. We also work with the participating laboratories´ procedures to minimize waste and encourage use of reusable glassware instead of disposable plastic.
Safety Considerations: Hazardous reagents and Biohazards
Health risks & Personal safety
Working in the lab always has implicit risks, but we have taken action to minimize them. Some of the precautions we take are listed here:
• The microorganisms are grown in large petri dishes that are sealed completely during bacterial growth, thus preventing their escape.
• Inoculation experiments are conducted on plants that are isolated in a greenhouse. Plants will be kept for a minimum time of experimentation and will be discarded as biohazard material immediately after the experiments.
• Equipment such as biological safety cabinet class I and laminar flow cabinets are used regularly to minimize the possibility of spread of microorganisms by recently trained students.
• All students involved with the project were informed of the established security arrangement and signed a commitment to strictly comply with the rules.
• Also, prior to the beginning of the experimental procedures, all of the team members were given a course on biosafety, focused mainly on biological hazards, chemical reagents and general BSL-1 laboratory safety concerns and security procedures.
The system design tests are conducted within a laboratory of biosafety level 1, and we use the following materials and microorganisms strains:
Bacterial strains:
Known toxic chemical reagents and hazardous physical agents:
Ethidium bromide
Since ethidium bromide is a very toxic agent, we have changed our nucleic acid staining molecules to [http://www.biotium.com/product/product_info/Protocol/PI-41001.pdf Biotium GelRed] and [http://www.invitrogen.com/site/us/en/home/Products-and-Services/Applications/DNA-RNA-Purification-Analysis/Nucleic-Acid-Gel-Electrophoresis/DNA-Stains/SYBR-Safe.htmlInvitrogen SYBR Safe]. Both of these claim to be significantly less toxic and better for the environment. Actually, both may have direct disposal into the wastewater drainage systems.
Ultraviolet light
It is a type of electromagnetic radiation with a shorter wavelength shorter than that of visible light. We use UV in the biological safety and laminar flow cabinets for sterilization and decontamination purposes. Also, UV radiation is used for visualization of the stained DNA in the electrophoretic gels.
In order to prevent accidental exposition to UV radiation, precautions are taken and when necessary, special safety lenses are used. We always use UV-blocking shields when visualizing electrophoretic gels in UV light.
All other toxic and chemicals will be handled to avoid direct contact, and observing the proper safety procedures, additionally, all chemicals reagents and biological materials will be disposed only in the designated biohazard receptacles, following the regulations for [http://departamentomedico.uniandes.edu.co//Documentos/Salud_Ocupacional/Procedimientomanejoresiduossolidos.pdf Guidelines for Integral Solid Waste Management] of the Medical and Occupational Health Department at the Universidad de los Andes.
