1. LAB SAFETY
Lets talk about lab safety.

2. INTRODUCTION
People are naturally curious. They want to understand the world around them. The field of science would probably not exist if it were not for human curiosity about the natural world.

3. INTRODUCTION
If you have ever wondered about why something happens and you wanted to explore what you observed then you displayed the basis of what science is about.

4. INTRODUCTION
Along with exploration comes some responsibilities, including the issue of safety. Not only your personal safety, but safety for others in the lab, and safety to ensure that lab equipment is not broken or abused.

5. INTRODUCTION
Experts agree, lack of safety in science labs not only endangers people but also produces poor results. The more effectively a scientist works, the better the data will be that they collect. A clean, safe lab is the starting point for valid and consistent experimentation.

6. INTRODUCTION
What kinds of rules about working on things in a science lab do you remember? Let’s list some of them on the board. Write down on the board.

7. OBJECTIVES Memorize the lab safety rules.
Prepare yourself to work safely in a lab setting.
Recognize common lab safety symbols.

8. VOCABULARY
Corrosive – eats away at other substances, usually through direct contact.
Toxic - can cause injury or death, by chemical means; poisonous.
Flammable – easily set on fire.
Contaminated – made impure by exposure to poison or polluted materials.

9. IN QUESTION
A friend tells you that only a scientist can “do” science. Do you agree with that statement? Why or why not?

10. LAB SAFETY RULES
1. No running or horseplay. Move purposefully and be aware of what’s around you.
When going into the lab make sure to WALK.  There will be no running in the lab.  There will be materials and equipment out that can break if you accidently knock into them.  There may be things on the ground that you may trip over as well.  Please WALK and be careful. No horseplay means that if it will cause harm, disrupt the lesson, or lead to an accident DON’T DO IT!

11. LAB SAFETY RULES
2. Wear proper safety attire, closed toe shoes and goggles & keep hair tied back.
Flip-flops, sandals and peep-toe shoes, are not allowed in the lab area.  You must wear closed toed shoes on the days we have lab.  If you do not have appropriate footwear on then you cannot participate in the lab.
HAIR MUST BE TIED BACK if you have long hair. When the instructor says so, it must be worn up in a ponytail.
SAFETY GOGGLES will be provided for you to be used in class when the instructor tells you to..  

12. SPECIAL NOTE
When the teacher says wear your goggles, that is not a request!!
If you don’t you will NOT be allowed to continue with the lab!!
Safety issues require students, that’s ya’ll to wear approved eye safety devices (goggles) whenever instructional programs involve the use of hot solids or liquids, caustic or explosive materials, and certain tools or machinery. In short, goggles must be worn in the laboratory whenever the instructor, that’s me, tells you they are needed. Not wearing goggles when instructed to do so will result in the student sitting out for the remainder of the class period.

13. 3. Handle chemicals and lab equipment safely.
LAB SAFETY NOTES
3. Handle chemicals and lab equipment safely.
Make sure to read directions, make sure to understand how to use the equipment, and if you are not sure what to do ask the teacher for help.

14. 4. Do not touch or attempt to clean up broken glass.
LAB SAFETY NOTES
4. Do not touch or attempt to clean up broken glass.
If you break a piece of glassware DO NOT TOUCH IT.  Tell the teacher IMMEDIATELY when it breaks.  I will then come over and properly dispose of it.

15. LAB SAFETY NOTES
5. Know where the safety equipment is and how to use it.
If chemicals or particles get in your eyes, WALK to the eye wash station and rinse out your eyes for 15 minutes.  Make sure that you keep your eyes OPEN when you rinse them. If a fire starts use PASS, pull, aim, squeeze, and sweep. If someone catches fire use the fire blanket to smother the flames. ALWAYS make sure to tell the teacher when something like this happens.

16. LAB SAFETY NOTES
6. Do not eat or drink in the lab. Never sniff or taste anything without permission.
There will be NO eating or drinking during lab.  There are days that we may be using chemicals and I do not want you to get sick.  Also, the lab tables may have had chemicals on them previously that were not properly cleaned up so you should not eat or drink on them either. 
Sometimes we will be using food as materials in lab, this too should not be eaten unless I tell you it is ok.  The food may have been stored next to chemicals in the lab and could be contaminated. Don’t sniff things directly, learn to waft the aroma to your nose.

17. INTRODUCTION
If you have no idea what it means to “waft” a smell to your nose, pay attention to the next slide.

18. INTRODUCTION

19. LAB SAFETY NOTES
7. Keep the lab areas, the equipment, and you clean and organized. Avoid clutter.
Once lab is over, I will give you enough time to clean your lab table.  If you used any chemicals make sure to dump them into the designated waste container. DO NOT POUR THEM DOWN THE SINK!  Once the beaker, flask, or test tube is empty then you can  rinse it out in the sink.  PLEASE REMEMBER TO TURN THE FAUCETS OFF. Make sure you wipe down your lab area as well.  Any materials will be put back where they belong (I will direct you to where they need to be on the day of the lab) Before leaving the lab ALWAYS wash your hands.  Make sure you wash your hands after handling chemicals or biological specimens.

20. LAB SAFETY NOTES
8. Don’t touch equipment until given permission, and never do unauthorized experiments.

21. INTRODUCTION
The next few slides are common safety symbols you will see in a lab setting. You need to know what they mean.

22. COMMON SAFETY SYMBOLS Corrosive
Corrosive means that something will eat away or gradually harm organic (living) or nonorganic (like some metals in acid) materials. Acids and strong bases, like drain cleaner are corrosive.

23. COMMON SAFETY SYMBOLS Toxic
Toxic means that the substance is poisonous. We keep a book with safety measures to take in the event that any of the chemicals that we use are misused either accidentally or on purpose. It’s called the MSDS Material Safety Data Sheet.

24. COMMON SAFETY SYMBOLS Flammable
Flammable means that it’s likely to catch fire if exposed to a heat source like a hot pad or an open flame.

25. COMMON SAFETY SYMBOLS Explosive Danger
This means that the substance could explode if not handles correctly.

26. COMMON SAFETY SYMBOLS Glass and Sharp Objects Hazard
Just like it says, if you drop something and it breaks notify the teacher, don’t try to clean it up yourself.

27. COMMON SAFETY SYMBOLS Radiation Hazard
This means that there is a danger of exposure to radiation. Any store that uses a microwave is required to display the symbol as a warning that microwaves are in use.

28. SUMMARY
The best way to enjoy this class is to obey these simple rules and always check with the teacher if you are not sure what to do.
My Golden Rule is:
Tell the teacher!!
