2. 17 October 2003 WRPPN Inspector Workshop Important Questions Consumers Ask What is really new and improved? What is really is GREEN? What is really safer for human health, but may be more harmful for aquatic life? What does “environmentally friendly” mean?

3. 17 October 2003 WRPPN Inspector Workshop Educate Consumers and Businesses on Basic Chemicals Include Toxics Education principles while on-site with Regulated Businesses Provide Toxics Education Workshops in an effort to increase chemical awareness Develop Toxics Education materials for dissemination to businesses The Answer: Toxics Education

4. 17 October 2003 WRPPN Inspector Workshop A Simple Idea Toxics Education Benefits Teach the consumers which chemicals to be wary of The consumers are empowered to purchase safer chemicals and affect chemical marketing and manufacturing

7. 17 October 2003 WRPPN Inspector Workshop Parts Washing Old Methods: Degreasing tanks using ketones, various acetates, petroleum blends with or without chlorinated hydrocarbons New Methods: Good aqueous substitutes that use hot soapy water: Dishwasher style Sink top style Ultrasonic Enzymes

8. 17 October 2003 WRPPN Inspector Workshop Brake Cleaning Old Methods: Solvent Dip Tanks Aerosol Cleaners New Methods: Water Dip Tanks Drying with Compressed Air No Aerosols Needed

9. 17 October 2003 WRPPN Inspector Workshop Aerosol Cleaning Positives Popular with Employees Easy to Use Product “hits” it’s Target Specific Cleaners Negatives Toxic Ingredients - “Toxic Soup” Propellant – Not an Active Ingredient More of an Inhalation Hazard due to Aerosol Form

10. 17 October 2003 WRPPN Inspector Workshop CARB Aerosol Regulations CARB regulates less than 2 gallon container sizes Regional air districts regulate the stationary sources Chlorinated Manufacturing Ban: 7/01/01 Chlorinated Use Ban: 1/01/03

11. 17 October 2003 WRPPN Inspector Workshop Aerosol Trends Aerosols: Most Toxic Solvents Chlorinated hydrocarbons- CNS, liver, carcinogen Methylene chloride (25 ppm) Perchloroethylene (25 ppm) Trichloroethylene (25 ppm) Trichlorethane (25 ppm) Brominated hydrocarbons- CNS, liver, reproductive toxin N-bromopropane (TLV not yet established) N-hexane- peripheral neuropathy (50 ppm)

12. 17 October 2003 WRPPN Inspector Workshop Aerosol Trends Aerosols: Most Toxic Solvents (Cont.) Aromatic hydrocarbons-CNS, liver Xylenes (100 ppm) Toluene (50 ppm) Ethylbenzene (100 ppm) Aromatic blends Methyl ethyl ketone- CNS (200 ppm) Cyclohexanone (25 ppm) Butanol (n-butanol 50 ppm) (tert-butanol, sec-butanol 100 ppm) Naphtha (coal tar 100 ppm) Volatile methyl siloxanes- uterine cancer (MSDS from 11/02 10ppm)

14. 17 October 2003 WRPPN Inspector Workshop Common Floor Cleaning Chemicals Acids (usually hydrochloric or sometimes a weaker acid) Sodium metasilicates in combination with a caustic or glycol ether Phosphate cleaners (TSP) Glycol ethers Various detergent and water solutions

15. 17 October 2003 WRPPN Inspector Workshop Floor Cleaning Best Practices Seal the floor Use dry floor clean-up methods Rags Hydrophobic Systems Eliminate the use of loose absorbent

16. 17 October 2003 WRPPN Inspector Workshop Education is the KEY Education is the key for inspectors in the millennium. We are the most knowledgeable about compliance issues, chemical hazards and looking at the whole picture. If we educate our regulated businesses a bit more, we will be seeing increased compliance as well as a good understanding of specific pollution prevention practices for that business. Simple and site specific toxics education is welcomed by businesses and makes us more effective in implementing P2 change.
