  1. LABORATORY CONDUCT AND SAFETY REGULATIONS(Indoor & Field Safety) Biology Lake City High School Mrs. Whittington

  2. Standard Standard B-1 The student will demonstrate an understanding of how scientific inquiry and technological design, including mathematical analysis, can be used appropriately to pose questions, seek answers, and develop solutions. • B-1.9 • Use appropriate safety procedures when conducting investigations. Safety regulations are established for each laboratory by Federal, State, and School mandates.

  3. Objectives Successful work in the laboratory and field involves not only mastery of concepts and techniques, but also knowing: • what the safety requirements are, • what equipment is available, and • when and how to use each piece of equipment • how to keep yourself and others safe and • how to respond to emergencies. Safety regulations are established for each laboratory by Federal, State, and School mandates.

  4. Universal precautions and basic lab safety rules will be strictly enforced

  5. NON-COMPLIANCE • 1st violation: leave the activity area until compliant • student may receive a zero for work missed • 2nd violation: leave the activity area for the day • student may receive a zero for all work missed that day

  6. NON-COMPLIANCE • 3rd violation: leave the activity area permanently • student may receive a failing lab grade • *Severe violations will warrant immediate removal from the lab • student may receive a failing lab grade

  7. Lab Safety

  8. STUDENT BEHAVIOR • No horseplay (pushing, shoving, etc...) in the lab • Always be aware of potential hazards & act cautiously in the lab

  9. Read, read, read • BEFORE beginning a lab READ ALL safety precautions and lab instructions..

  10. Eating & Drinking • Food and drink of any kind are strictly prohibited in the lab.

  16. Eye and Face Safety

  17. No contact lenses during wet labs (when using chemicals or biohazards) • Safety glasses during all wet labs • Disposable gloves when working with hazards or chemicals

  18. Eye Protection O Z87 Type Goggles

  19. NO Food, Drink, Tobacco, Cosmetic use

  20. Biology I Bell Ringer • You notice in the lab instructions that you will be using test tubes. What are two rules that you know you will need to remember? (Hint: There may be more than 2, but you only need to write about two.)

  21. Bell Ringer Free Write Friday • Write at least 3 sentences on whatever you like. • Examples: Tell me how your first week at school has been. Have any plans for the weekend? Be prepared to turn in your bell ringers.

  22.

Will be on Tuesday! • Put standards page in your folder. Initial the safety indicator (B 1.9) • 1st Period – Acceptable Use Policy!

  23. Assignment • You will be assigned a rule from the safety contract. • Your mission is to create a sign that will remind people to follow that rule. • Put your first and last name and the class period in the upper right hand corner. • Must communicate the rule • Must be creative and neat • Must finish in class

  24. Standard Standard B-1 The student will demonstrate an understanding of how scientific inquiry and technological design, including mathematical analysis, can be used appropriately to pose questions, seek answers, and develop solutions. • B-1.9 • Use appropriate safety procedures when conducting investigations.
