  1. Unit 8Spill Prevention and Floor Cleanup

  2. Baseline: Safety Hazards and Contaminated Wash Water

  3. Environmental Concerns • Sanitary sewer discharges • metals in treatment sludge • “pass through” contaminants • Storm drains discharge directly to surface water • Dry well discharges can contaminate groundwater

  4. P2: Use Roll-Around Drip Pans

  5. P2: Use Sloped Drum Covers

  6. P2: Secondary Containment

  7. P2: Overhead Bulk Delivery

  8. P2 Alternative: Dry Shop • Use dry clean up methods • Use launderable rags for small spills • Segregate spill wastes (4-step method) • Use absorbents sparingly • Epoxy-seal floor to reduce cleaning needs

  9. Making It Work Q1: Gasoline or solvent spill? If Yes Absorbents If No Q2

  10. Making It Work Q2: Cleanup with £ 3 rags? If Yes Use the rags If No Four-step floor cleanup

  11. Four-Step Floor Cleanup MOP WATER

  12. Step 1: Oil Spill? Use hydrophobic mop.

  13. Step 2: Antifreeze Spill? COOLANT ONLY Use dedicated antifreeze mop.

  14. Step 3: Dry Surface Wipe up with rags. Do not saturate.

  15. Step 4: Wet Mop Use mild, non-caustic detergent.

  16. Making It WorkMinimize Absorbents • Disadvantages: • Spilled oil and antifreeze cannot be recovered • Must be purchased repeatedly • May be a hazardous waste • Contaminants may be released to environment • Reserve absorbents for large spills and emergencies • Where possible, use reusable pads and pigs

  17. Making It Work Epoxy-Seal the Shop Floor • Won’t absorb spills as a concrete floor does • Makes spill cleanup easier • Requires less time and water to clean • Lasts for years and reduces long-term liability for floor contamination • Looks great to customers and worker

  18. Making It WorkPower Washing • Is wash water properly disposed? • Even if a contractor power washes the floor, you can be held liable for illegal disposal.

  19. Take Home Messages • Stop if there’s a drop! • Source segregation • Use absorbent sparingly • Epoxy floors make this easy
