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? WRPPN Inspector Workshop
The Answer:Toxics Education • 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 WRPPN Inspector Workshop
Toxics Education Benefits A Simple Idea The consumers are empowered to purchase safer chemicals and affect chemical marketing and manufacturing • Teach the consumers which chemicals to be wary of WRPPN Inspector Workshop
Chemical Usage Table WRPPN Inspector Workshop
Parts Washing • What industries have use for parts washers? • Auto Repair Shops • Building Facility Maintenance Shops • Fleet Maintenance • Machine Shops • Paint Shops 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 WRPPN Inspector Workshop
Brake Cleaning • Old Methods: • Solvent Dip Tanks • Aerosol Cleaners • New Methods: • Water Dip Tanks • Drying with Compressed Air • No Aerosols Needed 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 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 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) 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) WRPPN Inspector Workshop
Aerosol Trends Aerosols: Less Toxic Solvents • Heptane (400 ppm) • Acetone (750 ppm) • Isopropyl alcohol (400 ppm) • Methanol (200 ppm) • Ethanol (1000 ppm) • Methyl ethyl ketone- CNS (200 ppm) Aerosols: Least Toxic • Aqueous • None WRPPN Inspector Workshop
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 Common Floor Cleaning Chemicals WRPPN Inspector Workshop
Seal the floor Use dry floor clean-up methods Rags Hydrophobic Systems Eliminate the use of loose absorbent Floor Cleaning Best Practices 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. WRPPN Inspector Workshop
