Science Safety Rules For Secondary Science

The science lab is a place for responsible, adult behavior. By knowing and practicing the safety rules, will help prevent serious accidents to you and to others.

Most accidents can be prevented if you make safety a habit!

1. Never take any equipment or chemicals from the classroom without the teacher’s permission.
2. Never try any classroom science activity at home without asking the teacher first for permission.
3. Do not perform any experiments or science activity when your teacher is not in the classroom.
4. The science storage rooms are for authorized persons only, teachers only. You must have permission from your instructor to enter these rooms.
5. When working in the lab, shoes must be worn that completely cover the feet. Loose, baggy clothing must be secured and long hair must be tied back. Dangling jewelry must be removed.
6. Do not perform any unauthorized experiments. Do not handle equipment and chemicals at any lab station until you are instructed to do so.
7. Know where all emergency equipment is and know how to use it. Know the proper fire drill procedures.
8. Always wear safety goggles over your eyes when they are required.
9. Read and follow all directions very carefully. Listen to the teacher for additional verbal instructions before beginning the activity.
10. Focus on the work at your lab station at all times. Do not distract students at other lab stations. Do not borrow chemicals or equipment from other lab stations unless the teacher gives you permission.
11. When the teacher asks for your attention during the activity, immediately stop what you are doing and pay special attention.
12. Never work alone. When reading labels or measuring something, have your lab partner double check your readings. If you disagree on any procedure or measurement, contact the teacher to resolve the matter.
13. Know the proper name and proper use of all science equipment used in the activity. Never use a piece of equipment for anything other than what it was designed for.
14. If you have an accident or injury of any sort, notify the teacher immediately.
15. If you are doing a science project or experiment at home, you must get approval from your teacher before you begin.
16. Wash your hands after working in the lab.
Some other rules that may apply:
17. When observing the sun, use only an indirect method of observation.
18. When chiseling or grinding rocks, safety goggles must be worn.
19. Use caution when working with sharp instruments. Carry instruments with sharp ends pointing down.  When cutting, always cut away from your body.
20. Be aware of the mechanical advantage that some tools have and exercise caution when using them.
21. Inspect all electrical power cords for bare or frayed wires. Notify your instructor if you find one. Use caution when working with any power tools.
22. Do not use household electricity for experiments. Instead, use batteries or low voltage power supplies. When inserting or removing an electrical plug from it’s socket, grasp the plug and not cord.
23. When working with lasers, follow all precautions stated by the teacher and never look directly into the beam.
24. Look for dangerous situations with all science activities. Whether you are experimenting with w rockets, vacuum pumps, ultraviolet lamps or microwave devices, find out what the dangers are in advance! If you observe an unsafe situation, notify your instructor immediately.  

Life Science I Biology Safety Rules: In addition to the general rules, students should also follow the rules listed below for biology.
1. Take extra precautions when handling dangerous chemicals.

  1. Goggles must be worn over the eyes whenever required by the teacher. If you wear contact lenses, you should remove them and wear your glasses under your goggles whenever working with hazardous chemicals. You may wear contact lenses in the science lab only with the permission of the instructor.
  2. Know how to use the eyewash fountain. If a chemical gets in your eye, quickly rinse it with running water with your eye open and at the same time notify your teacher.
  3. Never eat food or drink liquids while working in the science lab. Never eat or drink from laboratory equipment.
  4. Never mix, touch, taste, smell or heat chemicals unless your teacher tells you that it is OK to do so.
  5. When testing for odors, hold the chemical about an arm’s length away and wave your hand over it, cautiously sniffing from a distance.

. 7.  Use caution when working with open flames. All excess chemicals should be placed well away from the flame. Loose clothing and jewelry, like necklaces, should not be worn near burner flames. Long hair should be tied back. Never reach over a flame to get something.

  1. Never point a test tube you are heating toward yourself or anyone else. Use a stirring rod or boiling chips when heating liquids.

9. Turn off the gas at the main valve when you are through using your burner.

  1. Be extra careful when working with hot objects. Do not place hot objects directly on the lab tables.

Handle all hot objects with clamps or tongs. Use the proper tool for the proper job.
