1. Mr. Villa Fall Semester

2.  Carelessness  Insufficient knowledge  Taking unnecessary risks  Being in too great a hurry

3.  Reading all procedures so you know what you are going to do  Following the procedures as they are written (Do not do “extra” experiments just for fun. The results may be dangerous or even deadly.)  Immediately report any accident or injury, no matter how minor, to your teacher

4.  Take this seriously  Fill out the answers to the questions  Bring back signed by parent tomorrow for a 100%

6. Dr. TT Aklinski HEALTH SPECIAL REACTIVITY (STABILITY) FLAMMABILITY

8. Dr. TT Aklinski Avoid water. May detonate with heat or ignition. Severe health risk. Burns readily. Diborane

9.  Material Safety Data Sheet  On file for all purchased chemicals.  Includes all information shown on a chemical label and more.  Different formats are used by different chemical companies. Dr. TT Aklinski

12.  Follow the teacher’s directions and do not perform any experiment the teacher has not authorized  Remember that the human body is a conductor of electricity  Never use electrical equipment with which you are not familiar or that contains no directions to follow  Hands and work areas, including floors and tables, should be dry  Never overload a circuit  Watch for exposed wires  Make sure all electrical equipment is properly grounded

13.  Never force glass tubing into rubber stoppers  Never pick up broken glass with your bare hands  Allow heated glassware to cool before touching it

14.  Never taste chemicals as a means of identification  Do not breathe fumes directly  Do not eat or drink in the laboratory  Do not eat or drink from laboratory glassware  Never handle mercury  Label reagent bottles properly  Read bottle labels carefully  Wash hands thoroughly after experiments  If any chemical comes in contact with your skin, rinse area with plenty of cold water and notify the teacher

15.  If any substance, liquid or powdered, splashes or blows into your eyes, wash them out immediately with water and notify your teacher  Wear safety goggles when necessary  All laboratories should have an emergency eye- wash station; know its location  Wearing contact lenses, even with goggles, is dangerous; fumes from chemicals can get under the lenses, causing eye damage

16.  Fire extinguishers and fire blankets should be available  Turn off hot plates or burners when not in use  Tie back hair and loose clothing  Use proper procedures when lighting laboratory burners  In case of fire, smother flames with a cloth or fire blanket  When heating the contents of a test tube, point the tube, away from yourself and others

17.  Take great care in noting odors or fumes; use a wafting motion of the hand  Use volatile liquids only in very small quantities and in a well ventilated room  Do not breathe pure gases such as hydrogen, argon, helium, or nitrogen (high concentrations of CO 2 can also be dangerous)  Turn off gas valves when not in use

18.  Confine loose clothing  Wear laboratory aprons

19.  Use safety shields or screens if there is a potential danger of an explosion or implosion of apparatus  Never use an open flame when working with volatile liquids such as alcohol

20.  Always use single-edged razors; double-edged razors are too dangerous  Handle any sharp instrument with extreme care; never cut any material towards you, always cut away from you  Notify your teacher immediately if you are cut in the lab

21.  Take particular care to handle glassware safely, and never use broken glassware  Never heat glassware that is not thoroughly dry; never pick up any glassware unless you are sure it is not hot; if it is hot, use heat-resistant gloves or beaker tongs  Always clean glassware thoroughly before putting it away  Fire polish ends of glass tubing; do not force glass tubing and funnels into rubber stoppers; glass tubing should be wrapped in toweling when being inserted or removed from rubber stoppers; a lubricant (glycerin or stop cock grease) is always used

22.  If any substance splashes or blows into your eyes, what should you do?  What kinds of safety apparel do you wear in the science laboratory?  If your partner wants to perform an experiment that he/she thought up, what should you tell him?  Before leaving the laboratory for your next class, what should you do?  A chemical solution has spilled on your skin. What is the first thing you need to do?  Draw a floor plan of your classroom and identify the location of the eyewash fountain, fire blanket, and fire extinguisher.  If your hair is long, what precautions will you take in the laboratory?  What does wafting mean?  Why is a lubricant used when inserting glass tubing into a rubber stopper?  List four main causes of laboratory accidents.

23.  Radioactivity  Glass Safety  Eye Safety  Animal Safety  Laser Safety  Explosive Safety  Sharp Objects  Biohazard  Poison Safety  Electrical Safety  Heat Safety  Fire Safety
