Anatomy Student Safety Contract
Purpose
Science is a hands-on laboratory class. You will be doing many laboratory activities that require the use of hazardous chemicals. Safety in the science classroom is the #1 priority for students, teachers, and parents. To ensure a safe science classroom, a list of rules has been developed and provided to you in this student safety contract. These rules must be followed at all times! Two copies of the contract are provided. Both you and a parent or guardian must sign one copy before you can participate in any laboratory activity. The second copy is to be kept in your science notebook as a constant reminder of the safety rules.
General Guidelines
1. Conduct yourself in a responsible manner at all times in the laboratory.
§ Never fool around in the lab.
· Horseplay, practical jokes, and pranks are dangerous and prohibited.
· Do not run, jump, or throw anything in the lab.
· Think before you act.
2. Follow all written and verbal instructions carefully and immediately. If you do not understand a direction or part of a procedure, ask the instructor before proceeding.
3. Never work in a laboratory without an instructor present in the room.
4. Do not touch any equipment, chemicals, or other materials in the laboratory area until you are instructed to do so.
5. Students are never permitted in the science storage or preparation areas unless given specific permission by their instructor.
6. Never remove any chemicals or other materials from the laboratory without the express permission of the instructor.
7. Do not eat food, drink beverages, or chew gum in the laboratory. Any open food or beverage may be confiscated. Do not use laboratory glassware as containers for food or beverages. Do not put any laboratory equipment or materials in your mouth for any reason.
8. Perform only those experiments authorized by the instructor. Never do anything in the lab that is not part of a laboratory procedure or approved by your instructor. Carefully follow all instructions, both written and oral. Unauthorized experiments are prohibited.
9. Be prepared for your work in the laboratory. Read all procedures thoroughly before entering the lab and be sure that you understand both the goals and procedure of the experiment.
10. Observe good housekeeping practices. Work areas should be kept clean and tidy at all times. Only materials needed for the lab should be out on the tables, and everything else should be put out of the way. Clean up spills immediately.
11. Keep aisles clear. Push chairs under the desks when not in use.
12. Know the locations and operating procedures of all safety equipment including first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket. Know where the fire alarm and exits are located.
13. Be alert and proceed with caution at all times in the laboratory. Notify the instructor immediately of any unsafe conditions you observe.
14. Dispose of all waste materials properly. Never mix chemicals in sink drains.
15. Sinks are to be used only for water and those solutions designated by the instructor.
16. All insoluble materials (such as solid chemicals, metals, matches, filter paper, paper towels, tissues, and oily liquids) are to be disposed of in the proper waste containers (trash can or special designated container if so instructed)—not in the sinks.
17. Labels and equipment instructions must be read carefully and understood before use. Set up and use the prescribed apparatus as directed. If you do not understand how to use a piece of equipment, ask the instructor for help.
18. Keep hands away from face, eyes, mouth, and body while using chemicals. Wash your hands with soap and water after performing all experiments.
19. Clean and wipe dry all work surfaces (including sinks) and apparatus at the end of the experiment. Return equipment clean and in working order to the proper location.
20. Experiments must be personally monitored at all times. You will be assigned a laboratory station at which to work. Do not wander around the room, distract other students, or interfere with the laboratory experiments of others.
21. Know what to do if there is a fire alarm during a laboratory period. Close all containers; turn off gas valves, microscopes, and any other electrical equipment.
22. Handle all living organisms used in a laboratory activity in a humane manner. Preserved biological materials are to be treated with respect and disposed of properly.
23. When using knives and sharp instruments, always carry with the tips pointing down and away.
24. Grasp sharp instruments only by the handles. Always cut away from your body and never try to catch falling sharp instruments.
Clothing
25. Any time chemicals, heat or glassware are used, students must wear safety glasses.
26. Dress appropriately for a laboratory activity
27. Wear protective aprons when
recommended by the instructor or
desired.
Accidents and Injuries
29. Report any accident (spill, breakage, etc.,) or any injury (cut, burn, etc.) to the instructor immediately, no matter how trivial it may appear.
30. In case of a burn or cut, place the injured area in cold water immediately.
31. If a chemical should splash in your eye(s) immediately flush with running water from the eyewash fountain or sink for 20 minutes. (Place eyes in the stream of water. Hold the eyelids open.) Notify the instructor immediately.
32. If a chemical should splash on your skin, immediately flush with running water (sink or safety shower). Notify the instructor immediately.
33. Clean up spills and broken glass promptly and thoroughly. Use broom or brush and pan for glass and solids—never use your hands. Use paper towel or solid absorbent for liquids. Wash the desktop after chemical spills. Place broken glass in the designated container.
34. It is impossible to predict every possible situation, so use common sense in the case of any accident.
Handling Chemicals
35. All chemicals in the lab are to be considered dangerous. Do not touch, taste, or smell any chemicals unless specifically instructed to do so.
36. If instructed to observe a smell, fan the fumes gently toward you over the top of the container.
37. Check the label on chemical bottles repeatedly before removing any of the contents. Take only as much chemical as you need. Keep containers closed except when using them.
38. Use proper methods for dispensing chemicals. If something is specifically provided with a chemical (designated dropper or spatula), use it. If nothing is provided, then pour or dump out what you need into another container. Never put chemicals directly on a balance pan.
39. Never return excess or unused chemicals to their original containers.
40. When transferring reagents from one container to another, hold the containers away from your body. When carrying chemicals from one part of the lab to another, hold them securely and walk carefully.
41. Handle flammable liquids over a pan to contain spills. Never have an open container of anything flammable anywhere near an open flame or source of heat.
42. All chemicals, especially acids and bases, must be handled with extreme care.
Handling Glassware
and Equipment
43. Use caution with electrical equipment. Grasp the plug, not the cord, when removing the plug from an outlet. Hands must be dry when touching an electrical switch, cord, or outlet. Report damaged electrical equipment immediately. Look for frayed cords, exposed wires, loose connections. Do not use damaged electrical equipment.
44. Examine glassware before each use. Never use chipped or cracked. Clean dirty glassware before use. Do not immerse hot glassware in cold water—it may shatter.
45. If you do not understand how to use a piece of equipment, ask the instructor for help.
Heating substances
46. Exercise extreme caution when using hot plate.
47. Never leave a chemical reaction or lab experiment unattended.
48. Turn off the hot plate when not in use.
49. You will be instructed in the proper method of heating liquids in test tubes. Do not point the open end of a test tube being heated at yourself or anyone else. Do not heat a sealed container of any type.
50. Heated metal and glass remain hot for a long time. Do not place anything hot on the laboratory desk. Set hot items aside to cool and pick up with caution. Use tongs or heat protective gloves (or hot hands) if needed.
51. In case of a clothing or hair fire, the victim should stop, drop to the floor, and roll to extinguish the flames. Another person should get the fire blanket and use it to smother the fire. Alternatively, use water to douse the fire (sink or shower).
52. In case of a small lab fire use the fire extinguisher to extinguish the flames using the PASS technique. PASS-Pull the pin, Aim, Squeeze the handle and Sweep. In some cases it may be safest to let a small quantity of material burn itself out.
53. If at any time it appears that a fire is spreading and will not be quickly and easily extinguished, pull the fire alarm and exit the building immediately.
End-of-Experiment Rules
54. When an experiment is completed, clean up your work area and return all equipment to its proper location.
55. Wash your hands before and after every experiment.
