Puromycin Dihydrochloride: Used at a concentration of 0.1 mg/ml. Plates will be incubated during one or two weeks and reincubated from time to time for a week. Cells will be kept in a 20 oC or 37oC incubator used for Dyctyostelium culture or for mammalian cell culture. 6 RISKS to HEALTH and SAFETY from INTENDED USE From personal exposure or hazardous reactions. Refer to OELs, flash points, etc., as appropriate. Are pregnant women, breast-feeding mothers especially at risk? G418 and Blastocidin: there is risk of inhalation when weighing powder and of skin contamination if in contact. Puromycin Dihydrochloride: harmful if ingested 7 CONCLUSIONS ABOUT RISKS Is level of risk acceptable? Can risk be prevented or reduced by change of substance/procedure? Are control measures necessary? The level of risk is not acceptable and the following control measures are necessary. 8 CONTROL MEASURES Additional to Good Chemical Practice G418, Lipofectamine, Fugene-6: Wear gloves, eye/face protection and suitable clothing. Avoid contact with skin and eyes. Do not swallow, do not breath dust, use only in fume hood. Puromycin Dihydrochloride: Wash hands, forearms and face thoroughly after handling the compound and before eating, smoking, using lavatory, and at the end of the day. Blastocidin: Store in a closed container in a +4 oC refrigerator. Material is toxic, avoid contact. Avoid prolonged or repeated exposure. Lab should be equipped with a safety shower and an eye wash station. Wash thoroughly after handling material. 9 INSTRUCTION/TRAINING Specify course(s) and/or special arrangements. Personnel involved in the use of this method must be adequately trained in handling cell culture materials, as well as toxic reagents. 10 MONITORING Performance of control measures, Personal exposure Health Surveillance 11 WASTE DISPOSAL PROCEDURE See School Server for Approved Procedure Document on specific Chemical Waste Disposal. Cells in general and stable transfectants in particular shall be transferred to autoclavable bags and autoclaved for 121oC for 50 minutes. Cells and medium containing, Fugene-6, Lipofectamine, G418 or Blastocidin are killed by this procedure. Place the waste into a yellow bag and seal for disposal. Liquid residues are aspirated into a flask containing bleach. 12 REVIEW Enter the date or circumstances for review of assessment (maximum review interval 5 years) March 2007 or when more is known about the toxicological properties of Blastocidin. 13 EMERGENCY ACTION TO CONTROL HAZARDS To stabilize situation eg spread absorbant on liquid spill; eliminate sources of ignition, etc. Spills and decontamination: G418: removed spilled material with water. Place into appropriate container for disposal. Avoid dust. Ventilate and wash spill area. Wear suitable clothing. Use gloves and eye/face protection. Lipofectamine, Fugene-6: Use an inert absorbent material (vermiculite, dry sand) to contain/pick up the spilled solution. Place all contaminated material into a suitable container, seal and label for disposal. Blastocidin: Evacuate area. Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Sweep up and place in a suitable container. Avoid raising dust. Hold for disposal using the special waste procedure (see Brian Facer in stores). Wash spill site and ventilate area after material pickup is complete. Puromycin Dihydrochloride: Splash goggles. Full suit. Boots, gloves, protective clothing might not be sufficient, consult a specialist before handling this product. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. TO PROTECT PERSONNEL Evacuation, protection for personnel involved in clean-up, Special First Aid First aid: G418, Lipofectamine, Fugene-6, Puromycin Dihydrochloride: Fresh air. If you feel unwell seek medical advice Skin contact:: G418, Lipofectamine, Fugene-6, Blastocidin, Puromycin Dihydrochloride: Take off contaminated clothes. Wash with soap and copious amounts of water, cold water in the case of Puromycin Dihydrochloride. Consult a physician. Eye contact: G418, Lipofectamine, Fugene-6, Blastocidin: Rinse eyes with copious amounts of water for at least 15 min, cold water in the case of Puromycin Dihydrochloride. Assure adequate flushing by separating the eyelids with fingers. Get medical attention immediately. Ingestion, inhalation: G418: If swallowed wash out with water, provided person is conscious. Consult a doctor. Lipofectamine, Fugene-6: Never give anything by mouth to an unconscious person. Get medical attention immediately. Blastocidin, Puromycin Dihydrochloride: Remove to fresh air and monitor breathing. If breathing becomes difficult, give oxygen and consult a physician. If breathing stops, give artificial respiration and consult a physician. If ingested, wash mouth out with water and consult the local poison centre and a physician. Puromycin Dihydrochloride: If ingested do not induce vomiting unless directed to do so by medical advice. Never give anything by mouth to an unconscious person. Get medical attention immediately. Loosen tight clothing such as collar, tie, belt or waistband. Clean-up/decontamination TO RENDER SITE OF EMERGENCY SAFE Spills and decontamination: G418: removed spilled material with water. Place into appropriate container for disposal. Avoid dust. Ventilate and wash spill area. Wear suitable clothing. Use gloves and eye/face protection. Lipofectamine, Fugene-6: Use an inert absorbent material (vermiculite, dry sand) to contain/pick up the spilled solution. Place all contaminated material into a suitable container, seal and label for disposal. Blastocidin: Evacuate area. Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Sweep up and place in a suitable container. Avoid raising dust. Hold for special waste (see Brian Facer in Stores) disposal. Wash spill site and ventilate area after material pickup is complete. Puromycin Dihydrochloride: Splash goggles. Full suit. Boots, gloves, protective clothing might not be sufficient, consult a specialist before handling this product. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Fire and explosion hazard: G418: Could cause fire in high temperatures. When heated to decomposition, materials emit toxic fumes (NO 4 and SO4). Lipofectamine, Fugene-6: use fire-extinguishing media appropriate for site conditions. Blastocidin: Upon thermal decomposition, it may emit toxic gases. Puromycin Dihydrochloride: These products are carbon oxides, nitrogen oxides…they emit toxic gases. For G418, Blastocidin and Puromycin Dihydrochloride , firefighters should wear self-contained breathing apparatus and full turnout gear. Emergency action in case of fire: G418: Fight fire with water, CO2 or powder. Blastocidin: Extinguishing media: dry chemical powder, CO 2, water, alcohol or polymer foam. Puromycin Dihydrochloride: Use dry chemical powder, or water spray, fog or foam. Not water jet. CONTACT L.M. Machesky PHONE 42504 10.10.00 * ** *** Prefix T is used for Teaching Assessment Number.
