REMEMBER THAT LATE PENALTIES WILL BE GIVEN FOR WORK WHICH IS SUBMITTED LATE!

PLAN AND CONSULT WITH DR. SHERREN.

Any unknown is submitted by giving Dr. Sherren the Student's Laboratory Record Book and the appropriate results section (including computer print outs and graphs), discussion section and conclusions on 8.5” x 11” paper. All reports are due at 4:30 P.M. on the dates listed above. Any report may be submitted early for early grading. If you have questions, you are encouraged to ask questions. All students are expected to sign in and out of the laboratory at the times that they are working. Also it is expected that at the end of the laboratory work period, each student will submit the laboratory record book to Dr. Sherren for a quick review of the day's work. Dr. Sherren will review, initial, and return the book to the student that day.

LABORATORY ATTENDANCE AND MAKE-UP LABORATORY SESSIONS: Laboratory attendance is expected of ALL students. Make-up laboratory sessions are a privilege. Make-up laboratory sessions are only permitted for certain reasons: personal illness with an official nurse's note; death of a spouse, sibling or parent; participation in a conference sporting event; court appearance; or an automobile accident on the way to laboratory. All make-up laboratory sessions must be arranged within one week of the missed laboratory session. Advance arrangements are preferred. No make up laboratory sessions will be held after the 9th week of the term.

CHM 210 LABORATORY DIRECTIONS1

**** BALANCE ETIQUETTE ****

l. Always pick up all paper and place in the trash can.

2. Always brush away all spilled chemicals on the balance table.

3. If chemicals are spilled in the balance, either brush away

completely or call the instructor for help.

4. Return all chemicals to the shelves of the laboratory (in

alphabetical order on the north wall of 114).

5. Remember that there may be others waiting, so try to limit

your operations to less than 15 minutes in time.

6. Call the next person waiting to use the balance.

**** HOOD ETIQUETTE ****

1. If chemicals are spilled in the hood, clean up the mess immediately or call the instructor for help.

2. Please return chemicals to the proper place immediately after using them.

**** OVEN ETIQUETTE ****

1. Always place your name in pencil on items you wish to recover.

2. Remove items promptly from the oven so that others can dry

their equipment.

3. Do not place corroding liquids in ANY oven without permission

of the instructor. (Water is the strongest liquid that may be

placed in the oven without permission.)

4. Take only those items which you have placed in the oven.

**** CHEMICAL USE ETIQUETTE ****

Avoid using excess amounts of reagents.

Never dispense more than the experiment calls for.

DO NOT RETURN EXCESS CHEMICALS TO THE REAGENT BOTTLE!

Good practice indicates that quick review of the MSDS Safety Sheets are needed when you first handle a chemical. If you have used a chemical in the past and feel comfortable with the properties of the chemical, then study of the MSDS is not needed.

NEVER taste, smell, or touch chemicals unless specifically told to do so. Skin, nasal, and/or eye irritations may result. Whenever your skin (hands, arms, face, etc.) comes into contact with chemicals, wash it quickly and thoroughly with soap and water. Use the eye wash fountain or safety wand to flush chemicals from the eyes and face. Get help immediately. Do not rub the affected area, especially the face or eyes, with your hands before washing. For large spills use the SAFETY SHOWER FOR AT LEAST 10 MINUTES. CALL FOR HELP IMMEDIATELY.

**** GENERAL RULE ****

If in doubt, ASK DR. SHERREN !!!!

ATS3/16/00

LABELS FOR CHEMICALS

All beakers, flasks, and bottles MUST be labeled. Good practice states that you will label all items. For any flask, bottle, or beaker that will be left overnight - USE A SAFETY DIAMOND LABEL WITH THE FULL INFORMATION.

HANDLING CHEMICALS

Handling chemicals is as safe as handling your dog. If handled carefully, no injuries will occur. Most techniques for the handling of chemicals are also regarded as safety guidelines.

Read the label on a reagent bottle at least twice before removing any chemical. The wrong chemical may lead to serious accidents or "unexplained" results. Never insert any object into a reagent bottle. The liquids will have droppers for your use.

Avoid using excess amounts of reagents. Never dispense more than the experiment calls for. DO NOT RETURN EXCESS CHEMICALS TO THE REAGENT BOTTLE!

Treat chemical spills in the laboratory as follows:

alert your neighbors and the laboratory instructor.

clean up the spill as directed by the laboratory instructor.

if the substance is volatile, flammable, or toxic, warn others of the accident.

Discard waste chemicals as directed in the experimental procedure of each experiment or by the laboratory instructor. Some suggested locations for the proper disposal of some substances are:

Sink:non-flammable, non-toxic, water soluble liquids and solids, followed by large amounts of water.

Waste basket:paper products only, such as litmus paper, filter paper, matches, and paper towels.

Marked Waste Containers:water-insoluble liquids, solids, toxic chemicals, and excess chemicals from the reagent container.

Marked Covered Containers:volatile liquids or very reactive chemicals.

CLEANUP

Clean up your work area and return all chemicals and equipment to their proper places.ATS 3/16/00
