2. Safety in the Chemistry Laboratory

4. Golden Rules In The Laboratory • Familiarize yourself with the laboratory. • 1. Gas and water outlets • 2. Fire exit, fire extinguishers

5. 3.First-aid kit, eyewash stations, blankets 4. Sandbox, safety shower

6. CLASSES OF FIRES

7. Class B fires involve flammable liquids and gasses, such as gasoline, paint thinner, kitchen grease, propane, and acetylene.

9. Class D fires involve exotic metals, such as magnesium, sodium, titanium.

10. FIRE EXTINGUISHERS Know the Different Types

12. Never work alone in the laboratory- perform only under the supervision of your teacher

13. Wear chemical splash goggles and protective shoes. Wear chemical resistant gloves Wear a lab coat and/or a chemical resistant apron

14. Remove necklaces or other dangling jewelry • If you have long hair, tie it back

16. Only books and notebooks needed for the experiment should be in the laboratory • Do not bring textbooks, purses, bags, or items in the laboratory

18. Followyourteacher’sdirections • Neverbegintheactivityunlessyourteachertellsyoutodo so • Never perform activities that are not authorized by your teacher • If the procedure is unclear ask for assistance • Carefully look for safety symbols or warnings provided for the experiment

21. No horseplay or fooling around in the laboratory • Clowning in the laboratory is dangerous • Always keep a watchful eye when carrying chemicals • Stay at your laboratory tables at prescribed times

25. Never eat nor drink inside the laboratory • Some chemicals may look like ordinary water or delicious candies • Keep your hands away from your face and mouth while working • No texting or phone calls while in the laboratory • Know the fire drill procedure and the location of exit doors

28. Be sure your hands are dry before using electrical equipment • Before plugging an electrical cord into a socket, make sure that the equipment is turned off • After using the equipment, turn it off, then unplug it • Cords should not lie in puddles of spilled liquid

29. Notify your teacher about problems- spill anything, break any glassware, cut yourself or your classmate, or encounter any unusual problems • Use tongs, gloves, or other equipment when handling hot objects • Avoid impossible transfers • If liquids are to be transferred from a large-mouthed container into a small-mouthed container, use pipette or funnel

30. Dispose of waste materials properly • Solid waste- waste can, liquid waste- sink • Never return chemicals to their original containers to avoid contamination • Clean as you go • Wash your hands before leaving the laboratory • Use your sixth sense- the common sense

33. First Aid and Emergency Measures

34. Acid on the Skin Wash the affected part with plenty of water, then wash it with dilute sodium bicarbonate solution, and finally wash it again with water. Then apply burn ointment on the affected area.

35. Alkali on the Skin Wash the affected part with plenty of water, then wash it with dilute boric acid solution, and finally wash it again with water. Then apply ointment on the affected part.

36. Organic Chemicals on the Skin Wash the affected part with plenty of water, then with rubbing alcohol. Afterwards, clean it well with soap and water. E.g. of organic chemicals are benzene, turpentine, and kerosene.

37. Poisoned by Swallowing Make sure that the victim vomit by letting him/her drink one glass of saltwater solution. Continuously give this until the expelled liquid is clear. Immediately bring the victim to the nearest hospital.

38. Cuts • Minor-cuts Let the cut bleed for a few seconds to remove any fragment from the wounded area. Apply disinfectant and cover it with bandage. • Serious Cuts Prevent excessive bleeding by applying pressure using a sterile pad over the wounded area . See a doctor immediately.

39. Eye accidents If you get chemicals in your eyes, go to the eyewash station or the nearest faucet and wash your eyes with running water. Hold your eyelids open with your thumb and fingers, and roll your eyeballs around. Flush your eyes continuously for at least 15 minutes. Never apply any chemical, for this may further irritate the eyes.

40. Thermal burns Apply ice on burning area until swelling subsides. Cold water may also be used. Do not apply bandage or ointment. Severe burns need the immediate attention of doctors.

41. Fire from burning chemicals Use a damp wet towel or rag to cover the mouth of the burning vessel to extinguish the fire and prevent it from spreading. Turn off all gas burners. In case of larger fire, use a fire extinguisher or dry sand.

42. Fire from burning clothing If your clothes catch fire, stay calm. Do not panic. Walk to the safety shower, stay under it, and turn it on. You can also use a wet laboratory gown to put out the fire.
