4. MY Responsibilities: • To provide safe learning activities (we’re NOT blowing anything up!) • To provide appropriate safety equipment • To provide verbal and written safety instructions whenever needed • To provide safety instruction

5. To follow instructions everyday, all day, without exception To read and double check all written safety instructions To ask questions when confused YOUR Students' Responsibilities

6. General Safety Information • All science classes have potential hazards • The more advanced the class, the greater the possibility for safety issues

7. Concerns & Issues for Science Classes • General hazard warning • When you see this symbol, triple check for safety issues

8. Safety Procedures • Planning is the key to safe science. • In case of an accident or emergency the teacher should stay with the problem and send a paraprofessional or student to an administrator for help. Follow local school procedures for reporting the accident. • Be aware of the location of fire extinguishers and how to operate them. • Teachers should be aware that certain chemicals, plants, animals, or odors can trigger allergic reactions in students. Science activities should be conducted in well-ventilated areas. Teachers need to check student contracts to identify students with identified allergy or asthma problems.

9. Safety Regulations • Occupational Safety and Health Act of 1970 • School District Policies • Professional Liability • Contributory Negligence (even if student is negligent, can still have % suit) • Keeping Records (Safety lectures, safety checks etc.) • Teacher's Responsibilities (Duty of Instruction and Supervision)

10. Laboratory Features • Location of Gas Main Valve • Location of Electrical Panel • Location of Water Main Control • Detecting Gas Leaks • Evacuation Procedures

11. Fire Extinguishers Fire Blankets Eye Washes Safety Showers Sand Bucket Dilute Acetic Acid or Boric Acid Sodium Hydrogen Carbonate First Aid Kit Emergency Equipment

12. 1. Each science classroom should be equipped with appropriate first-aid and safety materials First Aid

13. Safety showers must be provided in all areas where chemicals are handled. Safety showers must be located in areas that are accessible and unblocked by obstacles. The shower should have a quick opening valve which requires manual closing. Safety showers must be tested at least quarterly. Safety Showers

14. Eyewash Fountains /Eyewash Bottles • Eyewash fountains or Eyewash bottles must be provided in all laboratories where chemicals are handled. • Eyewash fountains must be capable of providing at least 15 minutes of water in a soft stream. • Fountains should be located close to the safety showers so that, if necessary, the eyes can be washed while the body is showered. • Eyewash fountains must be tested at least monthly.

15. All chemical operations that may generate air contaminants are to be conducted in a hood. Conduct all work at least 6 inches back from the face of the hood. Hoods are to be kept clear and the sash at the proper working height. Air flows will be routinely monitored by EH&S and the proper sash height noted. Laboratory Hoods

16. Adequate hand protection must be used when inserting glass tubing into stoppers or when placing rubber tubing on glass hose connections. Only glassware designed for vacuum work should be used for that purpose. Hand protection should be used when picking up broken glass. When rinsing glassware that contained chemistry, discard the first rinse volume into the appropriate waste container. Subsequent water rinses can be discarded to the sink. Glassware

17. Fire • If a fire occurs, pull the nearest building alarm. If you feel you can use a fire extinguisher safely, then follow the instructions below:NOTE: All fires do not use the same type of extinguisher media.Use the correct extinguisher for the specific fire. • Remove the fire extinguisher from the wall • Approach the fire with your escape route behind you. • If you don’t know how to operate a fire extinguisher, don’t attempt to fight the fire. Pull the alarm, close the door behind you and evacuate the area

18. Fire • Fire hazard • Use goggles • Tie back long hair • Tie back loose clothing

19. It is important that all chemical spills be responded to in a safe and expeditious manner by trained personnel. If a chemical is spilled in a quantity that can be safely cleaned up by he person causing the spill, then do so. If the quantity exceeds one quart, call Victor Gaither (404 – 802 - 3767). Chemical Spills

20. Safety goggles Eyes are very fragile Always protect them!

21. Goggle Use • Wear goggles when using: • Chemicals • Sharp objects • Fire • NON-NEGOTIABLE • It’s a LAW!

22. How to Disinfect Goggles • When using the safety goggle cabinet, the ultraviolet light timer should be set for a minimum of ten (10) minutes. • Chemical Disinfection: After student use, wash the goggles in soapy water followed by a ten (10) minute rinse in five percent bleach solution (10:1 ratio - 10 parts water to 1 part bleach). The goggles should be allowed to air dry.

23. Laboratory refrigerators must never be used for the storage of food or beverages. “Explosion-proof” refrigerators are to be used for storing flammable or combustible materials. Uncapped containers should never be placed in a refrigerator. Refrigerators

24. Corrosive • Corrosive Hazard • Wear goggles • Read labels • Wear apron • Keep off skin

25. Corrosives • Nitric acid is corrosive and its oxides are highly toxic. Because nitric acid is also an oxidizing agent, it may form flammable and explosive compounds with many materials (e.g., ethers, acetone and combustible materials). Paper used to wipe up nitric acid may ignite spontaneously when dry.

26. Poison • Poison Hazard • Wear goggles • Read label • Keep away from mouth

27. Electrical • Electrical Hazard • Watch for water • Be aware of cords

28. NEVER LEAVE THE GAS ON Always turn the gas taps in the lab OFF immediately after USE. Remember, a spark as small as the flick of a light switch could ignite A WHOLE ROOM THAT IS FILLED WITH GAS, along with anyone in or near it.

29. Tie up long hair in the lab!

30. Use tongs, test-tube holders, or pot holders to handle hot laboratory equipment. Allow ample time for glassware to cool before handling. (Remember, hot glass looks like cool glass.)

31. Compliance Environmental Protection Agency (EPA) Occupational safety & Health Administration (OSHA) Georgia Environmental Protection Division (EPD) Safety Lost of valuable financial resources Why organize chemical storage area?

32. This slide depicts several storage hazards. The storage unit is located in the classroom. The shelving unit shown is not designed to support the load which is applied; only four shelf clips support 100 pounds, which causes the shelf to deflect. The chemicals are not compatibly grouped and no shelf lips are present. Chemical Storage Area

33. This classroom storage unit is grossly overcrowded and is not designed for chemical storage. Chemical Storage Area

34. A 100 gram container of lithium sits on a shelf above a sink to which students have access. Water reactive chemicals are involved in many chemical accidents and are frequently stolen. Chemical Storage Area

35. Chemical accumulation is a problem in many schools. This 16x20 foot storage area contains 20 years of stockpiled chemicals. Chemicals are even stored on the hot air duct located 14 feet above the floor. Chemical Storage Area

36. Many Internet recipes for explosives list ingredients readily available from most high schools. These include: ammonium nitrate, other nitrates, chlorates, metal powders and water reactive chemicals. Chemical Storage Area

Step 3:Organizing Your Chemical Storage Area Step 4: Bag and can dangerous chemicals Step 5: Improve the chemical Storage Area Facility Step 6: Organize Chemicals by Compatible Families Step 7: Chemical Disposal

39. Chemical Labeling • Chemical containers must be labeled. • Portable chemical containers, intended only for the immediate use of the employee, do not require labels. • Remember, immediate use means that it can not be left unattended • Labels on incoming containers of hazardous materials should not be removed or defaced. Other information placed on the container should not obscure or detract from existing labels. • Recommendations found on labels should be read and followed.

40. Chemical Storage • All chemicals must be stored according to chemical compatibility. • Chemicals should be stored in areas designed for chemical storage. Storage rooms, storage cabinets, storage shelves and refrigerators are examples of appropriate areas. • Flammable liquids should be stored in approved flammable liquid storage cabinets. • Corrosives should be stored in approved corrosive storage cabinets

41. Chemical Storage • Chemicals must not be stored in offices, desks or file cabinets. • Chemicals should not be stored on bench tops because they are unprotected from potential exposure to fire and they are more readily knocked over. • Chemicals should not be stored on the floor or in the aisles. • Nothing may be stored on top of cabinets, shelves or shelf racks in the laboratory.

42. Hazardous Waste Disposal • Each teacher is responsible for his/her own waste in terms of proper preparation for waste disposal. • This is to include the use of proper containers and completing a waste identification tag in a neat and legible fashion with all the required information. • The use of laboratory sinks for the disposal of chemicals is strictly prohibited!

43. A MSDS is designed to provide both workers and emergency personnel with the proper procedures for handling or working with a particular substance. MSDS's include information such as physical data, health effects, first aid, reactivity, storage, disposal, and spill/leak procedures. Material Safety Data Sheets (MSDS)

44. Safety Contract • Each student and a parent or guardian will sign a safety contract. • Students without a signed contract on file will not be allowed to participate labs.
