EXPOSURE SERIOUSNESS

• Chemical composition

• The amount and concentration (dose)

• Length of exposure

• Route of exposure

• Synergism

• Sensitivity of the individual

• Work conditions

ROUTES OF EXPOSURE

• LUNGS

• SKIN

• INGESTION

RECOGNIZING HAZARDS

• Use of senses

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

ORDERING

• How often is the chemical used?• How is the chemical hazardous?• What is its educational value?• What is the cost of this chemical?• Can a less hazardous chemical be substituted?• Have I used the chemical?• Can I use the chemical safely?

PROPER STORAGE

• Shelves/cabinets attached to walls

• Shelves with anti-roll lips

• Wood construction

• Acids in acid cabinets (nitric acid)

• Flammables in flammable cabinet

• Sever poisons in poison cabinet

DANGEROUS CHEMICALS

• Carbon disulfide

flash point -22º F

• Ethyl ether / Isopropyl alcohol

store no longer than 3-6 months

• Potassium metal

develops peroxide crystals, reactive with water

• Picric acid / Perchloric acid forms explosive peroxides

• Mercury

CORRECTING PROBLEMS

• Maintain an accurate inventory

• Bag or can dangerous chemicals

• Organize chemicals by compatibility

• Arrange for disposal

• Purchase less / Use less / Substitute

• Date chemicals when received

• Discard when storage period is reached

• Store chemicals by compatibility• No more than a 2 years supply• 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• Containers must be labeled: name, CAS#, conc.• Emergency phone numbers posted with means of communication available

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.
