1006.063 Eye-protective devices required in certain laboratory courses.--
(1) Eye-protective devices shall be worn by students, teachers, and
visitors in courses including, but not limited to, chemistry, physics,
or chemical-physical laboratories, at any time at which the individual
is engaged in or observing an activity or the use of hazardous substances
likely to cause injury to the eyes.
“Personal protection devices which come in contact with the skin shall be sanitized after each
use” FL 6A-2.097
Mechanical SystemsVentilation
The ventilation system should provide adequateair changes for scienc laboratory rooms where biological or chemical investigations are beingconducted.

The Teacher’s Responsibility to Use Due Care
• The Duty of Instruct• The Duty to Supervise• The Duty to Properly Maintain
Equipment and Surroundings
The Duty to Instruct
FORESEEABILITY - Instruct students in problems that can be reasonably foreseen.
STANDARD OF CARE - Conform to standards established by the profession.
The Duty to Supervise
DEGREE OF SUPERVISION is commensurate with potential danger
STANDARD OF CARE - Conform to the Standards Established by the Profession (www.nsta.org)
The Duty to Maintain Equipment and Surroundings
KNOWLEDGE OF LAWS AND RULES
STANDARD OF CARE - Conform to the Standards Established by the Profession
Safety is an Attempt to Minimize the Risk of Harm
• The law only requires that a person is reasonable
• “Reasonable” is exercise of good common sense
• Negligence is conduct that falls below a standard established by law or by the profession
• Negligence is habitually being guilty of neglect
• Negligence is lacking in due care or concern
• Negligence is being extremely careless
