EXPOSURE LIMITS
• PEL – Permissible Exposure Limits
Specifies the maximum amount or
concentration of a chemical to
which a worker may be exposed.
Generally defined • Ceiling Limit (C): the concentration that must not
be exceeded at any part of the workday
• Short-Term Exposure Limit (STEL): the
maximum concentration to which workers may be
exposed for a short period of time (15 minutes)
• Time-Weighted Average (TWA): the average
concentration to which workers may be exposed
for a normal, 8-hour work day
POSSIBLE PROBLEMS
• Ordering
• Warehousing
• Storage

•
•
•
•
•
•
•

Date chemicals when received
Discard when storage period is reached
• Store chemicals by compatibility

• Concentrated acids / bases stored in approved
safety cabinets
• Oxidizers isolated and stored in approved
safety cabinets
• Chemicals stored below eye level, not protruding
over the shelf edge
• Shelves must have a raised edge

LEGAL
PERSPECTIVES
NJSA 18A:16-6
The Board shall provide indemnification to any person holding any
office, position or employment under the jurisdiction of the Board,
including any student teacher, or person assigned to other professional
pre-teaching field experience, for damages, losses, and costs incurred
as a result of a civil or administrative action suit or other legal
proceeding brought against any such persons for any acts or omissions
arising out of and in the course of their employment or student
teaching or other assignment to professional field experience with this
Board. This indemnification will include all costs of defending such
action, including reasonable counsel fees and expenses, together with
costs of appeal, if any, and will hold harmless and protect such person
from any financial loss resulting from such action. No employee will
be held harmless or have his/her defense costs defrayed in a
disciplinary proceeding instituted against him/her by the Board or
when the employee is appealing an action taken by the Board.
Indemnification for exemplary or punitive damages is not required and
will be governed by the standards and procedures set forth in N.J.S.A.
59:10-4. The Board may arrange for and maintain appropriate
insurance to cover all such damages, losses, and expenses.
POLICIES: HOW IS NEGLIGENCE DEFINED
TODAY?
• DUE CARE – A teacher’s duty is to insure
that instruction is appropriate
for these students.
• NEGLIGENCE – Conduct that falls below
a standard set by the law
or one’s profession.
• COMPARATIVE NEGLIGENCE
Who is to blame and to what extent?
Weigh all educational endeavors involving
students for their educational value versus
their “foreseeable” hazard.
If the hazard outweighs the educational value
of the activity and safety features then limit to
a teacher’s demo or eliminate the activity.
