Difference between revisions of "Team:IIT Kharagpur/Safety"

1. All eatables and beverages are strictly prohibited inside the laboratory.
2. Regular drills in fire escape and use of fire extinguishers. Emergency first aid box kit is always kept at easily accessible to hand places and is equipped with treatment for small cuts, burns and chemical spills. All members are trained in basic first aid skills.
3. Reusable and non reusable equipments are kept distinguish from each other and all the lab members take regular turn in disposing of waste materials in a sound scientific manner.
4. Wear laboratory coats and other appropriate protective clothing while performing laboratory activities. Feet and legs should be covered; sandals and open-toed shoes should not be worn in laboratories. Wear appropriate gloves while handling infectious or toxic materials and animals. Do not wear lab coats. Gloves or other personal protective equipment outside the laboratory.
5. Use a biological safety cabinet for handling infectious materials or materials requiring protection from contamination and a fume hood for toxic materials; mixed hazards need to be evaluated case by case.
6. Fume hoods should be used for laboratory activities that could result in chemical explosions or fires, for experiments involving toxic, hazardous or carcinogenic compounds and use of strong acids and bases. Biological safety cabinets should not be used for this kind of work.
7. Chemical and radioactive waste must not be poured down the drain. Learn the proper handling of all chemical substances before using them. In case of uncertainty ask a senior member to supervise your activities.
8. All materials should be kept at their proper positions after their use has been concluded. An alternate facility is maintained in case of regular storage rooms, fridges etc. are repaired or moved.
9. Never mouth pipettes anything. Use mechanical pipetting devices only!
10. Decontaminate all work surfaces daily, and decontaminate all spills immediately.
11. Decontaminate (by autoclaving or chemical disinfection) all biologically contaminated materials – glassware, animal cages, laboratory equipment, etc. – before washing, reuse or disposal. Discard materials via proper waste stream.
12. Syringes, needles, pipettes, etc, should be placed in rigid, leak-proof containers (Sharps Safe) and discarded following the waste rules.
13. Broken glassware and disposable pipettes (after decontamination) should be placed in a “Disposable Lab ware and Broken Glass Box” and discarded following the waste rules.
14. Wash your hands after handling chemicals, infectious materials, animals, after removing gloves and before leaving the laboratory.
15. The Biological waste is divided into two categories and handled accordingly:
>Liquid waste with biological factors is autoclaved and thereafter disposed of as hazardous waste in accordance with "Guideline for disposal of hazardous waste and problematic waste, ionizing sources of radiation and explosive waste.
>Solid waste is autoclaved and treated as residual waste if it does not contain chemical residues.

Biosafety at the workplace i.e our laboratory, for the working staff, the general population and finally, the environment is our top priority and is achieved by proper containment of biologically and chemically hazardous agents. Containment is ensured at research stage, when modifications are made, development work in the laboratory, greenhouse or growth room, The only risks involved are for those working in the laboratory and containment parameters are devised to ensure that the organism would not escape into the environment, or if it should, it would have been so designed not to survive in the open. All the handling of cell culture, bacterial colonies are carried out under laminar hood. The work bench, hood and hands of active members are washed both prior and after the laboratory work is done with rectified ethanol spirit. All the cell culture colonies are tightly wrapped with parafilm and maintained at 4 degree Celsius when not in use.
