FWPSAW3201
Treat timber


Application

This unit of competency describes the outcomes required to chemically treat timber and to operate the treatment plant to complete treatment cycles. Work is completed in a forest products factory setting.

The unit applies to those who treat timber in a forest products factory setting. Specific job roles can include treatment plant operator, kiln operator or timber products technician.

Copper Chrome Arsenate (CCA) chemical is a restricted chemical product, which means that CCA can only be supplied to and handled by suitably trained and authorised persons.

The Australian Pesticides and Veterinary Medicines Authority (APVMA) advised that as of 1 July 2012, CCA products can only be supplied to, and used by, suitably trained persons authorised under a relevant state or territory law from that date.

Licensing, legislative, regulatory, or certification requirements apply to this unit in some states and territories at the time of publication, and may differ according to jurisdiction.

In Victoria, to comply with licence/permit requirements, organisations must ensure that employees working with CCA demonstrate competence in this unit (FWPSAW3201 Treat timber), or that persons working with CCA do so under the direct supervision (sight and sound) of a trained and authorised person.

For regulatory information and details in other states and territories refer to the state or territory licensing body.
