Title: Sanding Waste Management

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

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

Sanding and Priming Area
Sand in designated area to control waste
5
Wet sanding
  • Best Practices
  • Squirt bottle
  • Minimizes water use
  • Collect wet sanding waste
  • Clarifier
  • Ensure adequate capacity and design
  • Inspect routinely and remove waste
  • Drip pans

Container cost 75.00 each
6
Vacuum Sanding
  • Central Vacuum System
  • Works well for large shops
  • Consider work station placement
  • Tools and sandpaper for most needs
  • Clean shop, clean paint jobs
  • Allows worker to see surface clearly
  • Dust removal from surface pores- brush
    attachments
  • Use efficient dust removal abrasive discs

High Efficiency Sanding Discs
8
Sanding Discs
More dust is collected more holes, more flow
area
Less dust is collected
9
Portable Vacuum Systems
  • Portable vacuum sanding units
  • May use for dedicated hazardous sanding waste
    collection
  • Less expensive than central systems
  • Shop-vac with HEPA filter
  • Use block sanding tool attachments
  • Clean-up after block sanding tasks

Why Vacuum Sanding?
  • Increase production
  • Save labor and material costs
  • Cleaner paint jobs
  • Reduces
  • Surface cleaning
  • Sandpaper use
  • Need to re-work
  • Maintain environmental compliance
  • Hazardous waste management and disposal
  • Storm water quality
  • Worker health safety
  • Reduces airborne contaminants
