Chemistry 152L - Laboratory Details (Syllabus, page 4)

Safety is the most important aspect of CHEM 152L. Please read the safety rules in Experiment #1 and pay attention during each pre-lab discussion. Additional rules will be presented each day for specific experiments. Violation of any safety rule may result in dismissal from class. If dismissed, you lose credit for the lab.

You are responsible for laboratory safety. You will be handling glassware, fire, and chemicals which may be flammable, corrosive, reactive, and/or otherwise toxic. The most frightening aspect of this is that your classmates (some of whom may not have read the lab manual nor listened very well in the prelab discussion) are handling the same dangerous materials. Each student must be responsible for following all safety rules.

Lab Drawers (or "lockers"). Groups of two students share lab equipment in a locked drawer. During check-in, you will sign a paper saying that you will return the drawer with all of the equipment in good condition at the end of the semester. Check-in is your opportunity to make sure it is all present and in good condition when you get it. Each "locker group" must purchase a lock from the Miramar Bookstore to place on the drawers. This provides easy access and security.

Dress for Lab. Wear old clothes. In general, if you would be sad to see a piece of clothing dissolve or become permanently stained, then don't wear it to lab (or wear a lab apron over it). Required clothing includes shoes with tops and safety goggles. Latex gloves are optional and available in the campus bookstore.

Goggles. You must wear goggles whenever anyone in the room is working with chemicals or lab equipment. Must be ANSI Z-87 certified safety goggles (not glasses with side-shields) are required.

Suggestions for Lab To do well in the lab and to write good lab reports, you must prepare ahead for each experiment. Before you walk in the door, you should read the lab manual and think through the whole experiment. Read your lab notebook and summarize the experiment in your own words: draw pictures, write a step-by-step procedure, make data tables, and think of questions that might show up on the prelab quiz. Quizzes will typically cover material from the experiment you are about to do and occasionally will include review questions from a previous experiment. Your time spent planning for each lab period will pay off in efficiency, speed, accuracy, and safety while you're in the lab.

Get to lab on time, so you can hear and participate in the pre-lab discussion. This is a safety-related requirement. If you arrive late, see me before you begin working on your experiment.

Students with Disabilities. Any student with a disability should discuss this with me during the first two weeks of class, so that we can make accommodations to enhance the learning process. You should also contact the DSPS office on campus. I will do my best to make the class workable for you.

Before you leave.

• Read the whiteboard. Check for announcements, assignments, and/or directions.
• Wash your hands.
• Clean up your benchtop.
• Wipe down the balances, if necessary.
• Return chemicals and borrowed equipment to original location.

• Push your chair in, under the benches.
• Don't forget to pass in your report.
