Unformatted text preview: Laboratory Safety Many o f the reagents (chemicals) and so me equipment in a bio logy laboratory are potentially dangerous. Following rules o f laboratory safet y and using co mmon sense throughout the course will enhance the learning experience by increasing the student’s confidence in his or her abilit y to use chemicals and equipment safely. The following rules of laboratory safety should not simply be memorized, but rather they should become habits. 1. Wear safet y glasses or goggles during exercises in which glassware and solut ions are heated, or during which dangerous fumes may be present, creating possible hazard to eyes, or contact lenses. 2. Assume that all reagents are poisonous and act accordingly. Read labels on chemical bottles for safet y precautions and know the nature of the chemical you are using. Your instructor will inform you of potentially dangerous materials and will give instructions as to their safe handling. If chemicals co me into contact with skin, wash immediately wit h water. 3. DO NOT a. ingest any reagents; b. eat, drink, or smoke in the laboratory. Toxic material may be present, and some chemicals are flammable; c. carry reagent bottles around the room; d. pipette anything by mouth; e. put chemicals in sink or trash unless instructed to do so; f. pour chemicals back into containers unless instructed to do so; g. operate any equipment until you are instructed in its use. 4. DO a. keep work area neat, clean and organized. Ask your instructor for assistance in cleaning up broken glassware and spills. Wash hands, desk area, and glassware at the end of each exercise and/or before leaving the laboratory. b. stopper all reagent bottles when not in use. Immediately wash reagents fro m yourself and your clothing if they spill on you, and immediately inform the instructor. c. handle hot glassware with testtube clamp or tongs. Use caution when using heat, especially when heat ing chemicals. Do not leave a flame unattended; do not light a Bunsen burner near a gas tank or cylinder; do not move a lit Bunsen burner; keep lo ng hair and loose clothing well away fro m the flame; make certain gas jets are off when Bunsen burner is not in use. Use proper ventilat ion and hoods when instructed. d. use extra care when working wit h scalpels, knives, and glass tubing. e. wear clothing which, if damaged, would not be a serious loss, or use aprons or laboratory coats, since so me chemicals may damage fabrics. f. wear shoes as protection against broken glass or spillage which may not have been adequately cleaned up. g. be familiar with the experiments you will be doing before coming to the laboratory. This will increase your understanding, enjo yment, and safet y during exercises. Confusion is dangerous. Completely fo llow the procedure set forth by the instructor. h. note the location of emergency equipment such as a first aid kit, eyewash
