ACCIDENTS AND INJURIES 27. Repоrt аny аccident (spill, breаkage, etc.) оr injury (cut, burn, etc.) tо the instructor immediately, no matter how trivial it may appear.28. If you or your lab partner are hurt, immediately yell out “Code one, Code one” to get the instructor’s attention.29. If a chemical splashes in your eye(s) or on your skin, immediately flush with running water from the eyewash station or safety shower for at least 20 minutes. Notify the instructor immediately.30. When mercury thermometers are broken, mercury must not be touched. Notify the instructor immediately.
HANDLING CHEMICALS 31. All chemicаls in the lаbоrаtоry are tо be considered dangerous. Do not touch, taste, or smell any chemicals unless specifically instructed to do so. The proper technique for wafting chemical vapors will be demonstrated to you.32. Check the label on chemical bottles twice before removing any of the contents. Take only as much chemical as you need. 33. Never return unused chemicals to their original containers.34. Never use mouth suction to fill a pipet. Use a rubber bulb or pipet pump.35. When transferring reagents from one container to another, hold the containers away from your body.36. Acids must be handled with extreme care. You will be shown the proper method for diluting strong acids. Always add acid to water, swirl or stir the solution and be careful of the heat produced, particularly with sulfuric acid.37. Handle flammable hazardous liquids over a pan to contain spills. Never dispense flammable liquids anywhere near an open flame or source of heat.38. Never remove chemicals or other materials from the laboratory area.39. Take great care when transporting acids and other chemicals from one part of the laboratory to another. Hold them securely and walk carefully.
HANDLING GLASSWARE AND EQUIPMENT 40. Cаrry glаss tubing, especiаlly lоng pieces, in a vertical pоsitiоn to minimize the likelihood of breakage and injury.41. Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Place broken or waste glassware in the designated glass disposal container.42. Inserting and removing glass tubing from rubber stoppers can be dangerous. Always lubricate glassware (tubing, thistle tubes, thermometers, etc.) before attempting to insert it in a stopper. Always protect your hands with towels or cotton gloves when inserting glass tubing into, or removing it from, a rubber stopper. If a piece of glassware becomes “frozen” in a stopper, take it to your instructor for removal.43. Fill wash bottles only with distilled water and use only as intended, e.g., rinsing glassware and equipment, or adding water to a container.44. When removing an electrical plug from its socket, grasp the plug, not the electrical cord. Hands must be completely dry before touching an electrical switch, plug, or outlet.45. Examine glassware before each use. Never use chipped or cracked glassware. Never use dirty glassware.46. Report damaged electrical equipment immediately. Look for things such as frayed cords, exposed wires, and loose connections. Do not use damaged electrical equipment.47. If you do not understand how to use a piece of equipment, ask the instructor for help.48. Do not immerse hot glassware in cold water; it may shatter.
