  1. HAZARDOUS CHEMICALRTK/HCS TRAINING Science Education Consultants 2008

  2. 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

  3. 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

  4. Re-train employees every 2 years Train employees whenever a new chemical is introduced to their work area

  5. EXPOSURE SERIOUSNESS • Chemical composition • The amount and concentration (dose) • Length of exposure • Route of exposure • Synergism • Sensitivity of the individual • Work conditions

  6. ROUTES OF EXPOSURE • LUNGS • SKIN • INGESTION

  7. RECOGNIZING HAZARDS • Use of senses • Work process • Forms of substance • Use of labels • PEOSH 300 Log

  8. 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

  9. EXAMPLES OF SYMPTOMS ACUTECHRONIC Dermatitis Emphysema Dry skin Pulmonary fibrosis Eye irritation Neurological degeneration Dizziness Blindness Nausea Paralysis Itching Cancer Shortness of breath

  10. HAZARD CLASSES HEALTH HAZARD PHYSICAL HAZARD • corrosives • flammables • irritants • reactives • poisons • oxidizers • carcinogens • explosives • reproductive hazard • sensitizers • asphyxiants • radioactive

  11. HIERARCHY OF HAZARDOUSSUBSTANCE CONTROL MEASURES • SUBSTITUTION 2. CHANGE THE PROCESS 3. ISOLATION 4. ENCLOSURE 5. GENERAL VENTILATION 6. LOCAL EXHAUST VENTILATION 7. ADMINISTRATION MEASURES 8. PERSONAL PROTECTIVE EQUIPMENT

  12. LABEL REQUIREMENTS Top 5 ingredients Hazardous ingredients > 1% Special hazards > 0.1% Name on Hazardous Substance List CAS number for each

  13. EXPOSURE LIMITS • PEL – Permissible Exposure Limits Specifies the maximum amount or concentration of a chemical to which a worker may be exposed.

  14. Generally defined - • Ceiling Limit (C): the concentration that must not be exceededat any part of the workday • Short-Term Exposure Limit (STEL): the maximum concentrationto 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

  15. POSSIBLE PROBLEMS • Ordering • Warehousing • Storage

  16. 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?

  17. COST OF CHEMICAL TOTAL COST Quantity + Storage + Disposal

  25. INCOMPATABILITY •Acetic Acid + Acetaldehyde polymerizes with high heat release • Acetic Anhydride + Acetaldehyde violent explosive reaction • Calcium Chlorate + Cupric Disulfide explodes on contact

  26. Organic Compatible Family Codes • 01 – Acids, Amino Acids, Anhydrides, Peracids • 02 – Alcohols, Glycols, Sugars, Amines, Amides Imines, Imides • 03 – Hydrocarbons, Esters, Aldehydes, Oils • 04 – Ethers, Ketones, Ketenes, Halogenated Hydrocarbons, Ethylene Oxide • 05 – Epoxy compounds, Isocyanates • 06 – Peroxides, Hydroperoxides, Azides • 07 – Sulfides, Polysulfides, Sulfoxides, Nitrites

  27. 08 – Phenols, Cresols • 09 – Dyes, Stains, Indicators • OM – Miscellaneous Flynn Scientific

  28. Inorganic Compatible Family Codes • I1 – Metals, Hydrides • I2 – Acetates, Halides, Iodides, Sulfates, Sulfites, Thiosulfates, Phosphates, Halogens • I3 – Amides, Nitrates (except Ammonium Nitrate) Nitrites, Azides • I4 – Hydroxides, Oxides, Silicates, Carbonates, Carbon • I5 – Sulfides, Selenides, Phosophides, Carbides, Nitrides

  29. I6 – Chlorates, Bromates, Iodates, Chlorites, Hydrochorites, Perchlorates, Pefchloric Acid, Peroxides, Hydrogen Peroxide • I7 – Arsenates, Cyanides, Cyanates • I8 – Borates, Chromates, Manganates, Permanganates • I9 – Acids (except Nitric) • I10 – Sulfur, Phosphorous, Pentoxide • IM – Miscellaneous Flynn Scientific

  30. 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

  31. 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

  32. Picric acid / Perchloric acid forms explosive peroxides • Mercury

  33. 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

  34. 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

  35. LEGAL PERSPECTIVES

  36. 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.

  37. 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.

  38. 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.
