Introduction to the Exercises The information provided here is applicable to all of the exercises. You are responsible for knowing this information throughout the semester and should become familiar with it before beginning the first exercise. Mandatory Safety Rules Rules and procedures that make for a safe working environment are described in more detail in each exercise. The rules listed below must be followed by everyone in the laboratory. No food or beverages are permitted in the laboratory. Smoking is strictly forbidden in the building. Know the nearest location and proper use of the safety kit, emergency shower and fire extinguisher. Do not place clothing, backpacks or other unnecessary items in your work area. A set of instructions for the work to be performed, a notebook and pen for taking notes and recording data, and perhaps a scientific calculator are all that is needed for most exercises. Always wear appropriate clothing in the laboratory. Closed shoes with hard soles are required at all times. Shorts and open-toed shoes are unacceptable due to potential risk of skin exposure. Loose-fitting jewelry or clothing are not permitted. Expensive clothing is strongly discouraged because of the possibility of stains or other damage resulting from spills. Protective gloves are encouraged during the performance of all laboratory experiments; they are required any time there is any possibility of skin exposure to a hazardous substance. Protective eyewear is required apparel at all times in many professional laboratories. Protective goggles or safety glasses are encouraged any time they do not interfere with a procedure such as microscopy. They are required any time a procedure entails a potential eye hazard. A laboratory coat or apron is not required. However, they are available and should be worn any time a hazardous substance is handled. Do not “play” with lab equipment or other lab materials – this is wasteful and potentially dangerous. Never rush when working with potentially dangerous items. Plan ahead, then work methodically through each procedure. Allow plenty of room for the person doing the work if others wish to watch while a procedure is performed by one individual. The chance of an accident is increased considerably when the person performing a procedure is crowded, or when two or more people are trying to work together in an uncoordinated way. Do not allow liquids or solid chemical substances used in the laboratory to come in direct contact with skin or clothing. Immediately wash with soap and water if a reagent in the laboratory accidentally touches your skin.

Do not use cracked or broken glassware. Do not use any item that appears to be damaged or broken unless the instructor states explicitly that it is safe. Broken or damaged items should be reported immediately to the laboratory instructor, and in most cases will be discarded. Do not carry boiling hot, caustic (causing chemical burns), or flammable solutions from one place to
