Safety+Rules


 * __ Student Safety Contract __**

The following rules are required for safety during labs in the chemistry classroom.

Please be aware that violation of these rules will result in removal from the lab and a grade of zero on this laboratory activity. This is not just arbitrary punishment - each year many students nationwide are badly injured because they have failed to work safely, and I am determined that you will not be one of them.

1) Always conduct yourself appropriately in the laboratory. Be serious and alert at all times. 2) Follow all written and verbal instructions carefully. If you are not certain about what to do after reading the instructions, please ask your teacher for clarification. 3) Never work alone in the laboratory. A teacher must always be present. 4) Do not touch any equipment or chemicals in the laboratory until your instructor has given permission. This includes the balances, which are very sensitive to tampering. 5) You may not eat or drink anything while performing a lab. 6) Keep your work area and walkways clear of debris, backpacks, books, and other obstacles. 7) Do not perform unauthorized experiments. 8) Know where all of the safety equipment is in the room and how to use it. 9) Don’t play with the safety equipment. 10) Use the fume hood when working with chemicals that give off toxic fumes. 11) Notify the instructor of any unsafe conditions you observe. 12) Wash your hands after touching anything in the laboratory. While working in the lab, keep your hands away from your face. 13) Pay attention to your experimental apparatus at all times. Unattended laboratory equipment is a serious hazard. 14) You are not allowed in the chemical storage room. 15) If there is a fire, all electrical equipment and equipment using gas must be shut off.
 * General safety rules:**

16) **Goggles must be worn in the laboratory at all times until __all__ students are finished working. Failure to wear goggles will result in a zero on the lab assignment and removal from the laboratory.** 17) Lab aprons should only be worn with teacher approval. Gloves are rarely worn…..if you don’t want something on your hands…..don’t get any on your hands. 18) Long hair must be tied back if an experiment involves fire. If you have long hair, be sure to keep some sort of hair tie in your locker for quick access when you need it. 19) Loose clothing and jewelry should be secured to prevent accidents. 20) Shoes that cover the feet must be worn. Sandals are not allowed.
 * Clothing and protective equipment:**

21) Instantly report any accident, spill, or injury to your instructor, no matter how minor. 22) If chemicals get in your eyes, flush them in the eyewash until professional medical assistance arrives.
 * Accidents and injuries:**

23) All chemicals in the laboratory are assumed to be dangerous. Never eat, touch, or smell any of them unless specifically told otherwise. 24) The proper way to smell chemicals are to waft the odors toward you with your hand, not to take a big sniff. 25) Chemicals should never be handled with your bare hands. Use a spatula. 26) Chemicals should never be placed directly on the balance. Use weighing paper, plastic weighing boats, or a beaker to weigh chemicals. 27) Always read the label of a chemical bottle before using it. 28) When moving reagents from one bottle to another, always hold both away from your body. 29) Never return unused chemicals to their original containers without prior permission. 30) Acids give off large amounts of heat when mixed with water. Always slowly add acid to water, never water to acid. 31) Never remove chemicals from the lab. 32) Be careful when moving chemicals from one part of the lab to another. 33) If you spill an acid or corrosive chemical on your skin, wash it off immediately using lots of water. 34) Dispose of chemicals properly. Your teacher will inform you of how to do this before the lab.
 * Using chemicals:**

35) Never handle broken glass with your bare hands. Use a brush and dustpan to clean it up and place it in a glass disposal container. 36) Never use dirty, cracked, or chipped glassware. 37) If you don’t know how to use a piece of equipment, ask your teacher. 38) Don’t put hot glassware in cold water – it will shatter. 39) Never press down on a balance – it will break.
 * Handling glassware and equipment:**

40) Keep combustible materials from open flames (especially alcohols, acetone, and anything that smells like gasoline). 41) Never place anything into a Bunsen burner flame that doesn’t belong there. 42) Never leave a lit Bunsen burner unattended. 43) When heating something in a test tube, point it away from yourself and others. 44) Before touching something that’s been heated on a hotplate or Bunsen burner, splash a few drops of water on it. If it sizzles, it’s too hot to touch. 45) Never look into anything that’s being heated. 46) Never heat anything in a closed container. 47) Never reach across a flame. 48) Turn off all Bunsen burners and hotplates before leaving the lab.
 * Heating substances:**

49) Handle sharp instruments with care. Always cut away from your body, not toward it.
 * Handling sharp instruments:**

50) Never use electrical equipment in areas that are wet or while you have wet hands. 51) When you are finished using a piece of electrical equipment, unplug it. 52) Report damaged electrical equipment promptly.
