There are a variety of hazards associated with working in a laboratory, just as there are hazards associated with cooking in a kitchen. Before you are allowed to begin any experiment involving chemicals, you must undergo training in chemical hazards, laboratory safety rules, and hazardous waste training. Then you must pass a safety quiz. You will also sign the Chemistry Lab Rules for Students and Safety Agreement. The purpose of this workshop is to make you aware of the hazards, so that you can minimize hazards to yourself and others in the laboratory. Minimization of hazards requires everyone to follow safety and lab practice rules.
Each CHEM 115 student will be required to pass a safety quiz with a 100% score before working with chemicals in the lab. At the start of each exercise is a table of all of the chemicals used in the exercise and their associated hazards. (The following table is an example.) There are three types of information given in these tables—chemical classification, chemical hazard (possibility of), and the National Fire Protection Agency (NFPA) code. The chemical classification scheme is designed to help identify the dominant properties of a given chemical, and to help segregate incompatible chemicals. The chemical hazard defines the dominant type of hazard associated with the chemical. The NFPA code helps to identify some major hazard(s) that may be associated with the chemical. The definitions of the chemical classifications, chemical hazards, and the NFPA system are included in the introduction to the Laboratory Manual.

Caution:
Anyone found acting contrary to the rules will be excluded from the remainder of the lab period and assigned a zero for that day's work.
For any serious injury or sudden illness, call campus police at 911 from any campus phone. Campus police have first responder and CPR training to assess the situation and decide if an ambulance needs to be called. The lab instructor should be notified of any injury (cut or burn) or chemical exposure (inhalation, splash on skin, clothes or eyes) immediately, and their instructions should be followed.
