LABORATORY SAFETYCOMMUNITY COLLEGE OF AURORASCIENCE DEPARTMENTIntroductionThe science laboratory is one of the safest environments around; it is considerablysafer than your home. The main reason for this is that although there are inherent dangerswhen working in the laboratory, everyone involved takes all the necessary precautions toprevent accidents from occurring. These precautions include being knowledgeable of theexperiment and respectful of the chemicals and biologicals involved.Safety is everyone’s concern. It starts with being prepared for each experiment.This means reading each laboratory BEFORE coming to the classroom and being awareof any hazardous material or procedure being performed. Before you start your firstexperiment, you Instructor will outline the safety procedures in this guide, locate thesafest equipment in the room, and describe the procedures if there is an accident.The most common laboratory injuries are cuts and burns. The best way to preventthese from happening is to be aware of your surroundings, know the safety procedures,and don’tdeviate from an approved procedure.Personal ProtectionThere are several things you can do to make the lab a safe haven. Much of this iscommon sense. The idea is to minimize the risk of chemical burns, fires, and electricalshocks. For your protection, here is a list of guidelines that must be followed.1.Safety goggles, rated for chemical splash protection will be worn at all timesin the chemistry lab and when designated by your instructor in any of theother labs. With these approvedgoggles, contact lenses can be worn.a.These goggles must be worn over your eyes, not resting comfortably onyour forehead.b.Goggles will be worn at all times, even if you are finished with theexperiment. Others may still be working.c.They can be purchased at the bookstore.2.You may need to wear gloves for some experiments. Your instructor will tellyou if this is necessary, and you should do as instructed. The purpose ofgloves is to act as an extra barrier to avoid skin contact. Gloves should beremoved whenever you leave the laboratory. Ideally your gloves should notbecome contaminated, but if you suspect they have replace them immediately.3.You will be required to wear lab coats in certain classes during lab time. Makesure you are always wearing it with buttons closed, not open, and that youtake it off when leaving the classroom.
4.Wear closed shoes that shed liquids. Canvas shoes, sandals, heels, and opentoed shoes are not permitted. This is true at all times for the chemistry lab.Your instructor will tell you if this is true for any of the other labs.5.Shorts and short skirts should not be worn.Skirts and pants should extend tobelow the knees. Otherwise they will not provide adequate protection for aspill on your legs. This is true at all times for the chemistry lab. Instructors inother areas will determine if this is necessary for any of the other laboratories.
