Chemistry Safety Contract

 

Purpose:

Science is a hands-on laboratory class.  Safety in the science classroom is the priority for students, teachers and parents.  To ensure a safe science classroom, this list of rules has been provided to you.  These rules must be followed at all times.  A contract stating that you will abide by all safety rules and procedures must be signed by you and your parent/guardians before you can participate in the laboratory.  This contract is available online for you to print out or read at any time.

 

General Guidelines:

  1. Conduct yourself in a responsible manner at all times in the laboratory.
  2. Follow all written and verbal instructions carefully.  If you do not understand a direction or part of a procedure, ask the instructor before proceeding.  Unauthorized experiments are not permitted.
  3. No student may work in the lab without an instructor present.
  4. Do not eat, drink or chew gum in the lab area.  Never use lab equipment as a container for food or drink.
  5. Never fool around, play jokes or roughhouse at any time in the laboratory.
  6. When first entering a science room, do not touch any equipment, chemicals, or other materials in the room until instructed to do so.
  7. Work areas should be kept clean and tidy at all times.  Bring only your labs, pencils and calculators into the lab area.  Do not allow paper towels to accumulate on the lab stations and keep the sinks free of debris.
  8. Know the locations and operating procedures of all safety equipment including the first aid kit, eye wash station, safety shower, fire extinguisher and fire blanket.
  9. Always work in a well-ventilated area.  Use a fume hood when working with volatile substances or poisonous vapors.  Never place your head in the fume hood.
  10. Notify the instructor of any accidents (spills, breakage, etc.) or injuries immediately, no matter how trivial it may seem.
  11. Dispose of all chemical waste properly.  Follow all disposal directions and check waste container labels twice before adding your chemical waste container labels twice before adding your chemical waste to the container.
  12. Wash hands with soap and water after performing all experiments.
  13. Students are never permitted into the science storage rooms or preparation areas unless given specific permission from the instructor.

 

Clothing:

  1. GOOGLES ARE TO BE WORN AT TIMES WHILE IN THE LABORATORY !!!!  There are no exceptions to this rule.
  2. Contact lenses should not be worn in the laboratory unless you have permission from your parent/guardian or doctor.

  2.  Check the label on chemicals twice before removing any chemicals.  Take only as much chemical as needed.
  3. If a chemical should splash on your skin or in your eyes, immediately flush with running water from the sink, safety shower or eye wash station for at least 20 minutes or until your instructor instructs you to stop.
  4. Never return chemicals to their original container.
  5. Acids must be handled with extreme care. Always add acid to water, swirl or stir the solution and be careful of the heat produced.

  4. Never look into a container that is being heated.

 

A statement acknowledging this contract and agreeing to abide by its rules and procedures is to be signed on the course document entitled “Chemistry Course Acknowledgement” before any laboratory experiments will be allowed.
