Wood preservation facilities, chromated copper arsenate: chapter B, table 15

Objectives:

• Minimize losses of preservative chemicals from treated wood to the environment by providing adequate controls to ensure minimization of preservative drippage prior to removal to unprotected storage areas
• Ensure fixation of preservative prior to release to uncontained storage area
• Reduce the time required for fixation from that required for ambient fixation

• Consider integrated design provisions for
  • area that is sheltered from precipitation, dust, debris;
  • adequate air flow; and
  • sufficient heat and humidity to achieve fixation.

• Area should have an impermeable floor and designed so that any residues may easily be cleaned up.
• Area should be fully contained with sufficient grade and an efficient drainage system to direct any free liquid to a collection and recycling system.
• Provide for return of fluids to treatment process with minimum dispersal from tracking by personnel and vehicles.
