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