"Your SaferSource for Science Supplies"
Science is a hands-onlaboratory class. You will be doing many laboratory activities whichrequire the use of hazardous chemicals. Safety in the scienceclassroom is the #1 priority for students, teachers, and parents. Toensure a safe science classroom, a list of rules has been developedand provided to you in this student safety contract. These rules mustbe followed at all times. Two copies of the contract are provided.One copy must be signed by both you and a parent or guardian beforeyou can participate in the laboratory. The second copy is to be keptin your science notebook as a constant reminder of the safetyrules.
1. Conduct yourself in aresponsible manner at all times in the laboratory.
2. Follow all writtenand verbal instructions carefully. If you do not understand adirection or part of a procedure, ask the instructor beforeproceeding.
3. Never work alone. Nostudent may work in the laboratory without an instructorpresent.
4. When first entering ascience room, do not touch any equipment, chemicals, or othermaterials in the laboratory area until you are instructed to doso.
5. Do not eat food,drink beverages, or chew gum in the laboratory. Do not use laboratoryglassware as containers for food or beverages.
6. Perform only thoseexperiments authorized by the instructor. Never do anything in thelaboratory that is not called for in the laboratory procedures or byyour instructor. Carefully follow all instructions, both written andoral. Unauthorized experiments are prohibited.
7. Be prepared for yourwork in the laboratory. Read all procedures thoroughly beforeentering the laboratory. Never fool around in the laboratory.Horseplay, practical jokes, and pranks are dangerous andprohibited.
8. Observe goodhousekeeping practices. Work areas should be kept clean and tidy atall times. Bring only your laboratory instructions, worksheets,and/or reports to the work area. Other materials (books, purses,backpacks, etc.) should be stored in the classroom area.
9. Keep aisles clear.Push your chair or stool under the desk when not in use.
10. Know the locationsand operating procedures of all safety equipment including the firstaid kit, eyewash station, safety shower, fire extinguisher, and fireblanket. Know where the fire alarm and the exits arelocated.
11. Always work in awell-ventilated area. Use the fume hood when working with volatilesubstances or poisonous vapors. Never place your head into the fumehood.
12. Be alert and proceedwith caution at all times in the laboratory. Notify the instructorimmediately of any unsafe conditions you observe.
13. Dispose of allchemical waste properly. Never mix chemicals in sink drains. Sinksare to be used only for water and those solutions designated by theinstructor. Solid chemicals, metals, matches, filter paper, and allother insoluble materials are to be disposed of in the proper wastecontainers, not in the sink. Check the label of all waste containerstwice before adding your chemical waste to the container.
14. Labels and equipmentinstructions must be read carefully before use. Set up and use theprescribed apparatus as directed in the laboratory instructions or byyour instructor.
15. Keep hands away fromface, eyes, mouth and body while using chemicals or preservedspecimens. Wash your hands with soap and water after performing allexperiments. Clean (with detergent), rinse, and wipe dry all worksurfaces (including the sink) and apparatus at the end of theexperiment. Return all equipment clean and in working order to theproper storage area.
16. Experiments must bepersonally monitored at all times. You will be assigned a laboratorystation at which to work. Do not wander around the room, distractother students, or interfere with the laboratory experiments ofothers.
17. Students are neverpermitted in the science storage rooms or preparation areas unlessgiven specific permission by their instructor.
18. Know what to do ifthere is a fire drill during a laboratory period; containers must beclosed, gas valves turned off, fume hoods turned off, and anyelectrical equipment turned off.
19. Handle all livingorganisms used in a laboratory activity in a humane manner. Preservedbiological materials are to be treated with respect and disposed ofproperly.
20. When using knivesand other sharp instruments, always carry with tips and pointspointing down and away. Always cut away from your body. Never try tocatch falling sharp instruments. Grasp sharp instruments only by thehandles.

34. Acids must behandled with extreme care. You will be shown the proper method fordiluting strong acids. Always add acid to water, swirl or stir thesolution and be careful of the heat produced, particularly withsulfuric acid.
35. Handle flammablehazardous liquids over a pan to contain spills. Never dispenseflammable liquids anywhere near an open flame or source ofheat.
36. Never removechemicals or other materials from the laboratory area.
37. Take great care whentransferring acids and other chemicals from one part of thelaboratory to another. Hold them securely and walkcarefully.
HandlingGlassware and Equipment
38. Carry glass tubing,especially long pieces, in a vertical position to minimize thelikelihood of breakage and injury.
39. Never handle brokenglass with your bare hands. Use a brush and dustpan to clean upbroken glass. Place broken or waste glassware in the designated glassdisposal container.

49. You will beinstructed in the proper method of heating and boiling liquids intest tubes. Do not point the open end of a test tube being heated atyourself or anyone else.
50. Heated metals andglass remain very hot for a long time. They should be set aside tocool and picked up with caution. Use tongs or heat-protective glovesif necessary.
51. Never look into acontainer that is being heated.
52. Do not place hotapparatus directly on the laboratory desk. Always use an insulatingpad. Allow plenty of time for hot apparatus to cool before touchingit.
53. When bending glass,allow time for the glass to cool before further handling. Hot andcold glass have the same visual appearance. Determine if an object ishot by bringing the back of your hand close to it prior to graspingit.
