  | Know the locations and operating procedure of all safety equipment including the first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket. Know where the fire alarm and the exits are located. |  | Always work in a well ventilated area. Use the fume hood when working with volatile substances or poisonous vapors. Never place your head into the fume hood. |  | Dispose of all chemical waste properly. Never mix chemicals in sink drains. Sinks are to be used only for water and those solutions designated by the instructor. Solid chemicals, metals, matches, filter paper, and all other insoluble materials are to be disposed of in the proper waste containers, not in the sink. Check the label of all waste containers twice before adding your chemical waste to the container. |  | Labels and equipment instructions must be read carefully before use. Set up and use the prescribed apparatus as directed in the laboratory instructions or by your instructor. |  | Students are never permitted in the science storage rooms or preparation areas unless given specific permission by their instructor. |  | When using knives and other sharp instruments, always cut with tips and points pointing down and away. Always cut away from your body. Never try to catch falling sharp instruments. Grasp sharp instruments only by the handles. |
 | Any time chemicals, heat, or glassware are used, students will wear laboratory goggles. There will be no exceptions to this rule! | | Dress properly during a laboratory activity. Long hair, dangling jewelry, and loose or baggy clothing are a hazard in the laboratory. Long hair must be tied back and dangling jewelry and loose or baggy clothing must be secured. Shoes must completely cover the foot. No sandals allowed. |
 | Report any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the instructor immediately, no matter how trivial it may appear. | | If a chemical should splash 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. |
 | All chemicals in the laboratory are to be considered dangerous. Do not touch, taste, or smell any chemicals unless specifically instructed to do so. The correct technique for smelling chemical fumes will be demonstrated to you. | | Check the label on chemical bottles twice before removing any of the contents. Take only as much chemical as you need. | | 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 | | 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. | | Inserting and removing glass tubing from rubber stopper can be dangerous. Always lubricate glassware (tubing, test 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. |
 | Exercise extreme caution when using a gas burner. Take care that hair, clothing and hands are a safe distance from the flame at all times. Do not put any substance into the flame unless specifically instructed to do so. Never reach over an exposed flame. Light gas (or alcohol) burners only as instructed by the teacher. | | Never leave a lit burner unattended. Never leave anything that is being heated or is visibly reacting unattended. Always turn the burner or hot plate off when not in use. | | You will be instructed in the proper method of heating and boiling liquids in test tubes. Do not point the open end of a test tube being heated at yourself or anyone else. | | Heated metals and glass remain very hot for a long time. They should be set aside to cool and picked up with caution. Use tongs or heat protective gloves if necessary. |
