Wood preservation facilities, ammoniacal copper zinc arsenate: chapter C-8

8. Operational Recommendations

The recommendations for good operating practices listed in the following tables must be used in conjunction with those in Part I, Chapter A - General Recommendations for All Wood Preservatives, Section 8.

8.1 Operational Standards

The registered pesticide labels are legal documents that must be followed when treating wood with wood preservatives. The labels state the required Personal Protective (PPE), the acceptable treatment solution concentrations and the target retention rates within the wood. While not a legal requirement, the Canadian Standards Association (CSA) O80 Series of Standards specifies a number of additional requirements including ACZA.

Those standards should be followed and applied in respect of applicable laws and regulations. Process controls should be installed, maintained and calibrated in accordance with CSA O80.2-08 Clause 4.1 (referenced to AWPA M3). The calibration can be conducted by facility staff if they have the appropriate training.

All tables of general content from Chapter A, Section 8 must be taken into consideration.

8.2 Facility Wide Recommendations

In order to develop a successful facility-specific worker safety and environmental protection protocol, it is important to have an operations manual that provides written instructions to employees for all aspects of chemical use.

Refer to Part I, Chapter A - General Recommendations for All Wood Preservatives, Section 8.2 and consult Table 17 and Table 18.

8.3 Area specific Recommendations

Table 20 provides additional recommended operating practices for process systems.

Table 21 provides additional recommended operating practices for kiln, accelerated stabilisation chamber and dripping area.

Table 22 provides additional recommended operating practices for maintenance, cleanout and shutdown of treatment systems.

User should refer also with Part I, Chapter A - Table 20, Table 21 and Table 22 since these tables should be used in conjunction.
