1. Safety Guidelines in the Laboratory

2. Objectives Recognize common safety symbols for Physics lab. Understand expectations of students in the Physics lab. Understand how to use SDS sheets. Understand experimental procedures.

4. Lab Safety Rap

5. General Safety Guidelines 1.Personal apparel should be appropriate for laboratory work. 2.NEVER work alone in the laboratory 3.Only books and notebooks needed for the experiment should be in the lab. 4.Read the entire experiment before entering the lab.

6. General Safety Guidelines 5. Always heed safety symbols and cautions written in the experimental investigations and handouts, posted in the room, and given verbally by your teacher. 6. Know the proper fire drill procedures and the location of fire exits and emergency equipment. 7. If your clothing catches on fire, do not run; WALK to the fire blanket, wrap up in it and roll. 8. Report all accidents to the teacher immediately, no matter how minor.

7. General Safety Guidelines 9.DO NOT perform unauthorized experiments or use materials and equipment in a manner for which they were not intended. 10. Stay alert in the lab, and proceed with caution. 11.Horseplay in the lab is very dangerous. 12.Food, beverages, chewing gum, and tobacco products are NEVER permitted in the laboratory.

8. General Safety Guidelines 13. Use extreme CAUTION when working with hot plates or other heating devices. 14. Exercise caution when working with electrical equipment. 15.Keep work areas and apparatus clean and neat.

13. Eye Safety Wear safety goggles when conducting any laboratory experiment. Know the location of the Eye-wash station and how to use it. Notify your teacher immediately if something comes in contact with your eyes.

14. Clothing Protection Wear your lab coats during any lab experiment or investigation. Lab coats help to prevent your clothing from stains or damage. No dangling jewelry. No loose clothing. No open toed shoes.

15. Glassware Safety Check all glassware prior to use. Look for chips or cracks. Broken, cracked or chipped glassware should not be used in experiments. Glass tubing should not be forced into rubber stoppers. (follow teacher instructions) Clean all glassware.

16. Sharp Objects Be careful when using knives, scalpels, or scissors. Always cut in the direction away from your body. Always cut in a direction away from your lab partner.

17. Heating Safety Keep heat sources turned off until needed. Use oven mitts to handle hot glassware. Point test tubes away from your body when heating.

18. Heating Safety Use pyrex glassware Do not pour hot liquids into plastic containers.

19. Fire Safety Tie back long hair Do not reach across open flames Roll up long sleeves or keep cuffs buttoned

20. Electrical Safety Check for worn or frayed cords before use Keep work area dry Do not overload circuits Keep electrical cords out of traffic areas

21. Poison/Chemical Handling Read the label of all bottles. Do not mix any chemicals unless directed to do so. Always add acid to water. Use the fume hood when necessary.

22. Poison/Chemical Handling Never taste any chemicals or lab substances. Keep your hands away from your face when working with chemicals. Wash your hands with soap and water after handling chemicals.

23. SDS An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. SDS format was adopted in 2012.product stewardshipworkplace safetymelting point boiling pointflash pointtoxicityhealth effectsfirst aidreactivity

24. SDS Safety data sheets are important in helping you, or anyone you supply, to make the workplace safe and to protect the environment. More specifically, a safety data sheet contains information to help you make a risk assessment as required by the Control of Substances Hazardous to Health Regulations (COSHH).

25. SDS Has eleven mandatory sections 1. Product Identification7. Handling 2. Hazards Identification8. Exposure 3. Composition/Ingredients9. Properties 4. First Aid measures10. Reactivity 5. Fire Fighting measures11. Toxicity 6. Accidental Release

26. SDS There are also five non-mandatory sections 12. Ecology Information 13. Disposal Considerations 14. Transport Information 15. Regulatory Information 16. Other Information – revision and changes

27. SDS

28. Animal Safety Do not bring wild animals into the classroom Do not cause pain and discomfort to an animal Keep all lab animals fed and watered Wash hands with soap and water after handling animals

29. Plant Safety Use caution when collecting plant specimens Do not eat or taste plants or plant parts If you are allergic to pollen, wear a face mask
