Wood preservation facilites, pentachlorophenol thermal: chapter F, table 20

Table 20. Additional Recommended Operating Practices for Process Systems

Operation	Recommendations
Objectives:	To define procedural practices to enhance environmental protection and worker safety To prevent worker contact with treatment solution and with freshly treated loads To operate the facility in compliance with the National Fire Code of Canada
Routine checks	Implement visual inspection routine at least once each shift for prompt detection of abnormal conditions (as per the NFCC). Frequently inspect and test all safety shutoff valves and other fire safety devices (as per the NFCC).
Charges	Secure loads to avoid uncontrolled floating. Stack loads to allow good drainage of preservative from all surfaces after treatment.
Treating tank lids	Ensure that lids fit tightly on tanks to minimize the release of vapours when tanks are not used.
Charge removal	Allow ventilation of the charge before unloading by exposing the open tank to air. Minimize exposure to vapours by working upwind of the charge and/or wearing an approved respirator. Maximize use of mechanical equipment for charge removal to minimize the need for worker handling of freshly treated wood. Remove charges from tank to drip pads only when preservative drippage has stopped.
