Wood preservation facilities, general recommendations: chapter A, table 15

Table 15. Recommended Design Features for Kilns and Accelerated Fixation Areas (All Preservatives)

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/stabilization of preservative prior to release to uncontained storage area.
Reduce the time required for fixation/stabilization from that required for ambient fixation/stabilization.

Design feature	Recommendations
General design	Consider integrated design provisions for area that is sheltered from precipitation, dust, debris; adequate air flow; sufficient heat and humidity to achieve fixation or promote stabilization.
Drip and containment	Should have an impermeable floor and be designed so that any residues may easily be cleaned up. Should be fully contained with sufficient grade and an efficient drainage system to direct any free liquid to a collection and recycling system. Fluids should be returned to the treatment process with minimum dispersal from tracking by personnel and vehicles.
