Make-up Exam SAFETY IN LABORATORY COURSES

Name Semester: Fall 2013-2014

To the student: You are required to read, understand and implement the safety precautions indicated in your laboratory manual or laboratory handouts, which are summarized below. Your signature on the attached sheet indicates your absolute willingness to abide by these precautions while you are in the laboratory.

1.Work in the laboratory only as authorized by your instructor. Do not perform unauthorized experiments. 2.You are required to purchase safety goggles and wear them as directed during some laboratory sessions. 3.Learn emergency procedures and know the locations of the nearest eye wash and chemical cleanup materials. 4.If you are injured or if any type of accident or fire occurs, IMMEDIATELY call your instructor for assistance. 5.Carefully read all instructions and thoroughly plan your work. 6.Wear appropriate clothing and shoes, not sandals, in the lab. Confine long hair. 7.Carefully read all labels on chemical bottles and familiarize yourself with the number/color hazards codes. Never return excess chemicals to the stock bottles. Do not put a pipet or a dropper directly into a commercial stock reagent bottle. Instead, pour an aliquot of the reagent from the stock bottle into a beaker. Use premixed lab reagents as directed in the instructions for specific laboratory exercises. 8.Do not eat, drink or smoke in the lab. Never taste chemicals. Smell chemicals cautiously by wafting the vapors toward you. 9.When mixing or heating chemicals in a test tube, point the test tube away from people. 10.Do not use Bunsen burners or other sources of spark or flame in the vicinity of flammable liquids. Note that most organic solvents are flammable. 11.While mixing acid and water, always add the acid to the water, not vice-versa. 12.Fill a pipette by using a pipette bulb or mechanical pipettor only; never pipette by mouth. 13.If a spill occurs during regular hours, refer it to your lab assistants or instructor or other trained person immediately. If a minor spill occurs when no senior person is available, clean it up immediately by using plenty of water. 14.Dispose of chemicals as directed by your assistant. Organic solvents are never to be disposed of down the sink. For disposable inorganics use plenty of water.

I have read carefully and understand all of the safety rules contained on this sheet. I also agree to read all rules for specific exercises contained in the laboratory manual or laboratory handouts required for this course. I recognize that it is my responsibility to obey them faithfully.

I realize that all chemicals are potentially dangerous; therefore I will exercise care in handling them. If I am unsure of the potential hazards of any chemical, I will discuss this with my assistant prior to using the chemical in question. I understand that I am required to wear safety goggles at all times when directed to do so in the laboratory. I also understand that there are dangers involved in wearing all types of contact lenses in laboratory situations where reactive chemical agents, biological fixatives, or volatile organics are in use. I am aware that even when safety goggles are worn, the Chemistry Department strongly discourages wearing of contact lenses in these situations. If I do elect to wear contact lenses in the laboratory, I will inform my assistant and I will assume all responsibility for damages caused by wearing them in the lab.

Date LAB REPORT FORMAT

Lab reports are to be prepared as instructed by your teaching assistants. A representative lab-report should include

1. Title Page 2. Purpose (1-2 sentences) 3. Introduction ( 1 page max) 4. Experimental (don't rewrite procedure, reference the lab manual and note differences. Maximum 5 sentences) 5. Results (3 pages max) 6. Calculations (Max. 4 pages) 7. Conclusions (1 page max) 8. Signed Statement

REPORTS CAN NOT BE COPIED FROM OTHER STUDENTS. IF ANY PART OF THE REPORT IS COPIED, YOU WILL SHARE THE GRADE WITH THE OTHER STUDENTS. (FOR EXAMPLE, IF TWO STUDENTS' REPORTS ARE THE SAME, THE MAXIMUM POSSIBLE GRADE WILL BE 50. IF 10 STUDENTS' REPORTS ARE THE SAME, THE MAXIMUM POSSIBLE GRADE WILL BE 10.

SIGNED STATEMENT:

I have only worked with the following persons ______for this lab experiment. I received no other help and I did not copy another person's work.

Signature : ______

An automatic 50% reduction in the lab report grade will be applied if this statement is not included.
