HAZARDOUS CHEMICAL RTK/HCS TRAINING Science Education Consultants 2008
REQUIREMENTS OF RTK Post RTK poster Distribute RTK brochure to every employee Maintain Central File RTK Survey MSDS Sheets HSFS Sheet Hazardous Substance List Complete survey/inventory every 5 years Complete updates to inventory every year
REQUIREMENTS OF HCS Identify responsible staff Develop and implement a written program Identify hazardous chemicals Maintain an updated list of hazard chemical Obtain MSDS & HSFS All containers labeled Train employees prior to them starting work with hazard substances
Re-train employees every 2 years Train employees whenever a new chemical is introduced to their work area
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 Work process Forms of substance Use of labels PEOSH 300 Log
HEALTH EFFECTS Conditions that result in disease and illness ACUTE CHRONIC Immediate Latency period Often reversible Generally not Can identify cause Difficult to identify High dose-short time Small dose-long time
EXAMPLES OF SYMPTOMS ACUTE CHRONIC Dermatitis Emphysema Dry skin Pulmonary fibrosis Eye irritation Neurological degeneration Dizziness Blindness Nausea Paralysis Itching Cancer Shortness of breath
HIERARCHY OF HAZARDOUS SUBSTANCE CONTROL MEASURES 1.SUBSTITUTION 2. CHANGE THE PROCESS 3. ISOLATION 4. ENCLOSURE 5. GENERAL VENTILATION 6. LOCAL EXHAUST VENTILATION 7. ADMINISTRATION MEASURES 8. PERSONAL PROTECTIVE EQUIPMENT
LABEL REQUIREMENTS Top 5 ingredients Hazardous ingredients > 1% Special hazards > 0.1% Name on Hazardous Substance List CAS number for each
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?
COST OF CHEMICAL TOTAL COST Quantity + Storage + Disposal
INCOMPATABILITY Acetic Acid + Acetaldehyde polymerizes with high heat release Acetic Anhydride + Acetaldehyde violent explosive reaction Calcium Chlorate + Cupric Disulfide explodes on contact
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
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 teachers duty is to insure that instruction is appropriate for these students. NEGLIGENCE – Conduct that falls below a standard set by the law or ones 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 teachers demo or eliminate the activity.
