| Feature | Characteristics |
| Treated wood use limitations in Canada (3) | For industrial and non-industrial wood products for above-ground, ground, or freshwater contact, or for treatable wood products out of water but subject to saltwater splash in the following categories: Residential construction such as decks, patios, fencing, play structures, siding, plywood and sill plates, as well as recreational applications such as walkways, boardwalks, landscaping, docks, gazebos and picnic tables General construction and commercial applications such as dimensional lumber, structural timbers, posts and decking Agriculture and horticulture applications such as fencing, framing and building poles Also used in highway construction and as lumber and timbers for bridges, bridge decking, hand rails, spacer blocks and posts Do not use to treat utility poles and pilings. *Note: permitted uses and limitations of CA-B-treated wood may change over time. Refer to pesticide label for up-to-date uses. |
| General process of application | Pressure treatment (refer to the pesticide label for details) |
The CSA O80 Series of Standards specifies requirements related to the preservation and fire retardance of wood through chemical treatment (pressure), which includes CA-B treated products. (4)
Treatment conditions must be calibrated to yield the target retention levels described on the pesticide label
