Laboratory Safety

• If you see anything in the classroom/lab that is
  dangerous, tell the teacher at once.
• Rags or paper towels with flammable liquids or

• To prevent accidents during lab activities with
  chemicals and equipment, you should follow
  directions.
• Playing (as opposed to working) in the laboratory
  or bothering another person is always against the
  rules.

Laboratory Safety

• To be able to put out a fire quickly and safely,

• When diluting acids, the proper procedure is
  adding acid to water.

  baking soda.
• Spilled bases can be made safe with vinegar.

10
Laboratory Safety

• You must wear approved eye protection while in
  the laboratory as directed by the teacher.
• You should prepare for each lab activity by
  reading all instruction before you do the
  experiment.

11
Laboratory Safety

• When measuring small amounts of liquids with a
  pipet, draw the liquid up into the tube by using
  a rubber suction bulb or pump.
• When heating substances in a test tube, be sure
  the open end of the bulb points toward no other
  person.

Laboratory Safety

• To remove an electrical plug from its socket, you

• When there is a fire drill you should know the
  proper procedures

14
Laboratory Safety

• When cleaning up, put chemicals into designated
  containers

15
Laboratory Safety

• Science is a hands-on laboratory class. Students
  will be doing many laboratory activities which
  require the use of chemicals. Safety in the
  science classroom is the 1 priority for
  students, teachers, and parents. To ensure a
  safe science classroom, a list of rules has been
  developed and provided to you. These rules must
  be followed at all times.

16
Laboratory Safety

• I have a no tolerance for inappropriate behavior
  during a laboratory activity. Students will be
  asked once to stop the inappropriate behavior.
  The second time it occurs the student will be
  asked to stand in the hall until the activity is
  complete
