Science Class Safety

Science Class Safety Practices
"Safety In The Laboratory"
Purpose

The course you will be taking this year will allow you to do many experiments. If you do them properly, they are perfectly safe, and very few accidents should occur. The book has been written so that there are instructions and drawings to help you do each of the activities. In addition to doing each activity, you should observe the following rules. Two copies will be provided. One copy must be signed by both you and your parent or guardian before you can participate in the laboratory. The second copy is to be kept in your science notebook as a constant reminder of the safety rules.

General Guidelines
  • Clear all laboratory stations of books, purses, notebooks, or other items not related to the laboratory work. It is suggested that these items be left in your locker.
  • Your work area should be left clean. Clean all pieces of equipment after use and return them to the supply area.
  • Throw waste materials into the proper containers.
  • Do not chew gum, eat or drink in the laboratory. Never taste any chemicals.
  • Wash your hands after each lab when instructed to do so.
  • Horseplay can lead to chemical spills, accidental fires, broken containers, injuries, and damage to equipment. Be careful where yo put your hands and arms and stay in your designated area during the lab.
  • Better safe than sorry. If you have questions or are not sure how to handle a chemical, ask your teacher. Think safety first!!
Clothing
  • Goggles must be worn whenever you are working with chemicals, are heating materials in test tubes, or could be harmed by flying objects (this is required by State law).
  • Dress properly during a laboratory activity. Long hear, dangling jewelry, and baggy clothing are a hazard in the laboratory. No sandals allowed.
Accidents And Injuries
  • Wipe up spills with damp paper towels.
  • Report any accidents to your teacher immediately.
Handling Chemicals
  • Handle all chemicals carefully. Keep them away from your eyes, ears, nose, mouth, clothing and skin.
  • Read labels. Use chemicals only from containers that are clearly labeled.
  • Measure all samples at the supply table so that you take to your work area only the amounts you need.
  • Always replace caps, covers, and stoppers on chemical containers.
  • Mix chemicals according to instructions only.
  • Avoid breathing the fumes of chemicals.
Handling Glassware And Equipment
  • Equipment and chemicals should be used only in the classroom, unless your teacher gives you permission to use them elsewhere.
Heating Substances
  • When heating chemicals in a test tube, keep the open end of the tube pointed away from yourself or anyone else.
  • Take special care in handling hot objects such as beakers, burner stands and burners.
  • Glowing pieces of wood or paper must not be placed in the waste containers and must be immersed in water before disposal.
Questions
  • Do you wear contact lenses?
  • Are you color blind?
  • Do you have allergies?
