Using Common Sense
Most laboratory precautions are nothing more than common sense. The laboratory is not a place for horseplay. Do not work alone in the laboratory. Do not perform unauthorized experiments. Do not sniff, inhale, touch or taste organic compounds, and do not pipette them by mouth. Wipe acids and bases. Neutralize residual spilled acid with sodium bicarbonate and spilled base with dilute acetic acid. Do not put dangerous chemicals in the waste crock – the janitor may become injured. Do not pour chemicals down the sink – the environment will be injured. Instead, use the containers provided for chemical disposal. When working in the laboratory, wear suitable clothing. Jeans and a shirt will
rolled-up sleeves, plus a rubber lab apron or cloth lab coat, are ideal. Do not wear your best clothing laboratory attire usually acquires many small holes from acid splatters and may also develop a distinctive aroma. Loose sleeves can sweep flasks from the laboratory bench, and they present the added hazard of easily catching on fire. Long hair should be tied back. Broken glass sometimes litters the floor of a laboratory; therefore, always wear shoes. Sandals are inadequate because they do not protect the feet from spills. Wash your hands frequently, and always wash them before leaving the laboratory, even to go to the rest room. Because of the danger of fires, smoking is prohibited in laboratories. Because of the danger of chemical contamination also, food and drink also have no place in the laboratory. On the first day of class, familiarize yourself with the locations of the fire extinguishers, fire blanket,eyewash fountain and shower.
