Select timber preservation techniques

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency describes the outcomes required to select timber preservation techniques taking into account the principles of environmental suitability and sustainability.

The unit applies to those working in technical roles in the forestry and forest products industry.

No licensing, legislative, regulatory, or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

ELEMENTS

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions.

1. Determine preservation requirements for timber

1.1 Identify service requirements for preservation of timber.

1.2 Identify required chemical retention rates and calculate suitable solution strengths.

1.3 Identify penetration pattern of timber for treatment.

2. Decide on appropriate preservation technique/s for timber

2.1 Investigate options for preservation techniques for job requirements and their environmental impact.

2.2 Review and compare options for suitability and value.

2.3 Select most appropriate preservation technique.

2.4 Identify and follow water management procedures.

2.5 Develop contingency management plans.

2.6 Implement quality assurance procedures for preserving timber.

2.7 Implement environmental monitoring procedures.

A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. If a specific volume or frequency is not stated below, then evidence must be provided that the following requirements have been performed on at least one occasion:

follow organisational procedures for selecting timber preservation techniques

select the most suitable preservation technique for different types of timber considering chemical retention rates and preservation patterns.

A person competent in this unit must be able to demonstrate knowledge of:

organisational procedures for preserving timber and selecting timber preservation techniques

environmental risks and hazards associated with different preservation techniques

timber preservation chemicals and their safe use and storage

timber preservation techniques including:

full cell (Bethel) process

empty cell process

rueping process

double treatment

boultonising

Australian Standards for timber preservation and market requirements, particularly Australian Standard (AS) 1604.1-2010 Specification for preservative treatment - Sawn and round timber and in Queensland, the Queensland Timber Utilisation and Marketing Act

service requirements including:

treated timber hazard ratings

marine borer hazard ratings

timber durability ratings

chemical retention rate/s including the amount of preservative retained in a piece of timber after treatment and fixation have taken place, and must be expressed as either weight for volume or weight for weight.

preservation patterns including the distribution of preservative within the cross section of a treated piece of timber.

water management procedures including consideration of:

ground water monitoring

bund storages

contaminated water containment

contaminated water reuse

drip pads

contingency plans including consideration of:

chemical handling and spill procedures

groundwater leakage procedures

fire suppression procedures

emergency evacuation procedures

environmental monitoring procedures including monitoring of:

groundwater

chemical disposal

residue disposal

dust

noise

types of tools and equipment, used for timber preservation and their safe use and maintenance.

The following resources must be made available:

organisational policies and procedures for selecting timber preservation techniques

examples of preservatives and end uses from which candidates must select appropriate chemicals and techniques.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessor requirements

Assessors must:

hold the appropriate assessor competency standards as outlined in regulations; and

be able to demonstrate vocational competencies at least to the level being assessed; and

be able to demonstrate how they are continuing to develop their VET knowledge and skills as well as maintaining their industry currency and assessor competence.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
