LABORATORY CONDUCT AND
SAFETY REGULATIONS(Indoor & Field Safety)
BiologyLake City High School
Mrs. Whittington
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.
Standard
• B-1.9 • Use appropriate safety procedures
when conducting investigations.Safety regulations are established for
each laboratory by Federal, State, and School mandates.
Successful work in the laboratory and field involves not only mastery of concepts and techniques, but also knowing:
Objectives
• 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.
Universal precautions
and basic lab safety
rules will be strictly
enforced
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
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
Lab Safety
STUDENT BEHAVIOR
• No horseplay (pushing, shoving, etc...) in the lab
• Always be aware of potential hazards & act
cautiously in the lab
Read, read, read• BEFORE beginning a
lab READ ALL safety precautions and lab
instructions..
Eating & Drinking• Food and drink of any
kind are strictly prohibited in the lab.
• Report all medical conditions (pregnancy, cardiac or respiratory disorders, allergies....)
• Only authorized people in the lab.
• All human secretions will be treated as biohazards
Stow books, backpacks, purses, etc... under the desk
APPAREL
• Lab aprons (tied in back)
• Long hair must be tied back
• Only closed toed shoes
Proper Clothing
Avoid floppyclothing!
Tie back loose hair!
Store belongingsout of the way!
Never take any lab materials out of the lab.• Lab materials are costly and
may be dangerous as well.• Taking them may result in
school discipline or even legal prosecution.
Eye and Face Safety
• 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
Eye Protection
Z87 Type Goggles
O
NO Food, Drink, Tobacco, Cosmetic use
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.)
Bell RingerFree 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.
Today• Reminder Safety Contracts due today.
– You may turn it in late for a point reduction.• Anyone miss yesterday’s pre-test?
– Everyone must take the pre-test• Safety Quiz – Postponed due to printer
issues. Will be on Tuesday!• Put standards page in your folder. Initial the
safety indicator (B 1.9)• 1st Period – Acceptable Use Policy!
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
