2. SCIENCE LABORATORY SAFETY is the RESPONSIBILITY of EVERYONE!

3. Safety First • Science is a class that involves many interesting and exciting laboratory activities intended to help you learn and discover! • However, the laboratory activities will require the use of unfamiliar items such as chemicals, specialized tools, organisms, and expensive lab equipment. • Safety in the science classroom is the #1 priority. This will ensure that students learn without injury and the science laboratory experience is available for all students. • To ensure a safe science classroom, a list of rules has been developed and provided to you in your Safety Agreement. • These rules must be followed at all times. • A signed Safety Agreement is required to participate in laboratory activities. • A student will be removed from the science laboratory immediately for his/her personal safety and the safety of all other students if the rules in the Science Laboratory Safety Rules are not followed.

4. Respect & Responsibility Conduct yourself in a respectful and responsible manner at all times in the science laboratory!

5. Respect & Responsibility What is wrong in these situations?

6. Clothing Requirements • Long hair, baggy clothing, dangling jewelry, sandals, shorts, skirts/dresses are safety hazards in the laboratory. • To participate in science laboratory activities: • Long hair must be tied back. • Clothing must be fitted. • Dangling jewelry must be removed. • Closed-toe shoes and pants must be worn. • Be prepared - Laboratory activities begin with an attire check!

7. Clothing Requirements Which hair style, clothing, and shoes meets the requirements? Why?

8. Laboratory Environment • Work areas should be kept clean and orderly at all times. • Bring only your science book and writing instruments to the work area. • Books or supplies should not be placed on the laboratory counters or floor. • Books and supplies not related to the science laboratory activities should be placed in the student’s assigned drawer or locker. • Jackets, bags, or purses are not allowed in the science laboratory and should be placed in the student’s assigned locker.

10. Equipment • Do not touch any equipment, supplies, organisms, or other materials in the science laboratory and classroom without permission from the teacher. • Use equipment (including scissors and sharp items) only as directed by teacher.

11. Equipment What can you observe about the equipment in these photos?

12. Instructions & Lab Activities • Follow all written and verbal instructions carefully. • Ask questions if you do not understand the instructions. • Perform only approved science laboratory activities, and do not stray from the instructions. • Remember to always read the laboratory activity for homework the night before a lab.

13. Personal Safety • To keep ourselves safe, we must take safety precautions in the science laboratory: • Wash your hands with soap and water before and after the science laboratory activity. • Never eat, drink, chew gum, or taste anything in the science laboratory. • Never put on makeup or Chap Stick in the science laboratory. • Keep hands away from face, eyes, and mouth while using science laboratory materials. • When directed to “sniff” in the lab, do not place nose over item. Follow the teacher’s directions for “wafting” the odor to the nose.

14. Personal Safety • Wafting: • Hold the substance in one hand. • Wave your other hand over the container towards your face. • Gently sniff.

15. Safety Equipment • Wear and use safety equipment including goggles, gloves, and safety tongs or mittens. • Never remove safety goggles during a science laboratory activity. There are no exceptions to this rule! • Cold or very hot materials can only be touched with heat safety items such as safety tongs, safety mittens, or rubber gloves. • Wear safety gloves and do not remove the gloves unless instructed to do so.

16. Safety Equipment Goggle Song The "Goggle Song" is sung to the tune of "I'm a Little Teapot." I'm a little scientist, short and stout. Here are my goggles, here are my eyes. When I don't wear my goggles, my teacher shouts, PUT THEM ON OR YOU GET OUT!

17. Safety Equipment What can you observe about the students safety equipment in these photos?

18. Accidents • Report any accident (spill, breakage, etc.), injury, or broken equipment to the teacher immediately. • Students should not clean up spills or broken items! Let the teacher know so that the teacher or custodian can take care of the spill or broken glass. • Glass should be used cautiously and chipped, cracked, or scratched glassware should never be used.

19. Clean Up • It is expected that laboratory students will clean all work areas and equipment at the end of a laboratory activity. • This means… • Dispose properly of any and all waste materials. • Properly clean and store glass. • Properly store equipment, materials, and specimens. • Clean work area. • Wash hands.

20. Clean Up • Waste Disposal: • First ask your teacher where and how to dispose of waste. • Never pour anything down the drain unless you are told to do so. • A waste bottle will be supplied for substance that cannot go down the drain.

21. Emergency • Learn how to handle emergency situations. Remember – • If you have an emergency situation, yell: Help

22. Emergency • Learn where the safety equipment is located and how to use it. • Fire Extinguisher: • There is one fire extinguisher at the front of the classroom. There is another fire extinguisher in the hallway outside the front door of the classroom. • There are three doors in the classroom that you can exit from in the event of a fire.

23. Emergency • Fire Blanket: • Do not panic. • Shout out for help: Code 1. • Open the container that holds the fire blanket and remove it. • Open the blanket up and throw it over the fire. • Never wrap a person in a fire blanket who is standing upright. This will cause a chimney effect. If a person is on fire, they need to stop, drop, and roll. Then throw cover over the person.

24. Emergency • Eye Wash: • Do not panic. • Shout out for help: Code 1. • Get to the eye wash station and turn the eye wash on. • Rinse both eyes with water for a minimum of 15 minutes. • Keep your eyelids open by using your hands to ensure adequate flushing of the eyes.

25. Emergency • Body Wash: • Do not panic. • Shout out for help: Code 1. • Get to the body wash station and turn the body wash on. • Rinse off the area that has been affected.

30. What’s Wrong With These Statements? • Mohammad says that his teacher is solely responsible for preventing laboratory accidents. • Keshia started the laboratory activity before reading it through completely. • Ricardo decided to see what would happen if he mixed the two substances even though the laboratory activity did not say to do so. • Stephanie says that the safety goggles mess up her hair and give her raccoon eyes. She takes them off when the teacher is not looking. • Alex and Tasha accidentally break a beaker full of some chemical. Instead of risking getting in trouble, they quickly clean up the mess with paper towel and throw it in the garbage.
