2. Sanding Waste Environmental & Health Concerns Hazardous waste Hazardous waste May contain heavy metals May contain heavy metals Restoration shops - lead, cadmium, chromium, zinc Restoration shops - lead, cadmium, chromium, zinc Shops working on newer cars Shops working on newer cars Newer paints contain less toxic materials, except zinc-based primers Newer paints contain less toxic materials, except zinc-based primers Sanding zinc primers may generate non-RCRA waste Sanding zinc primers may generate non-RCRA waste May be able to test or show non-hazardous May be able to test or show non-hazardous Storm water Storm water Waste tracked outside Waste tracked outside Sweeping or washing to parking lot, gutters, streets, storm drains Sweeping or washing to parking lot, gutters, streets, storm drains Worker Health and Safety Worker Health and Safety Dust particles in the air during sanding Dust particles in the air during sanding Take home hazard –dust carried on clothing and footwear Take home hazard –dust carried on clothing and footwear

3. Block Sanding Dust Control Best practices Sand in designated area Sand in designated area Clean up after each task Clean up after each task Wear PPE Wear PPE Respirator, tyvek or coveralls Respirator, tyvek or coveralls Sanding body filler Choose non-hazardous product Choose non-hazardous product Separate from primer sanding waste, usually hazardous Separate from primer sanding waste, usually hazardous

4. Sanding and Priming Area Sand in designated area to control waste

5. Wet sanding Best Practices: Squirt bottle Squirt bottle Minimizes water use Minimizes water use Collect wet sanding waste Collect wet sanding waste Clarifier Clarifier Ensure adequate capacity and design Ensure adequate capacity and design Inspect routinely and remove waste Inspect routinely and remove waste Drip pans Drip pans Container cost = $75.00 each

6. Vacuum Sanding Central Vacuum System Central Vacuum System Works well for large shops Consider work station placement Tools and sandpaper for most needs Tools and sandpaper for most needs Clean shop, clean paint jobs Clean shop, clean paint jobs Allows worker to see surface clearly Allows worker to see surface clearly Dust removal from surface pores- brush attachments Dust removal from surface pores- brush attachments Use efficient dust removal abrasive discs Use efficient dust removal abrasive discs

7. High Efficiency Sanding Discs

8. Sanding Discs Less dust is collected More dust is collected – more holes, more flow area

9. Portable Vacuum Systems Portable vacuum sanding units Portable vacuum sanding units May use for dedicated hazardous sanding waste collection May use for dedicated hazardous sanding waste collection Less expensive than central systems Less expensive than central systems Shop-vac with HEPA filter Shop-vac with HEPA filter Use block sanding tool attachments Use block sanding tool attachments Clean-up after block sanding tasks Clean-up after block sanding tasks
