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


Table 20. Additional Recommended Operating Practices for Process Systems

(Use in conjunction with Part I, Chapter A - General Recommendations for All Wood Preservatives, Table 20.)

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.
