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 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. Prepare for treating timber | 1.1 Review work order and where required check with appropriate personnel. 1.2 Select appropriate personal protective equipment and check for operational effectiveness. 1.3 Obtain chemicals and type and quantity of timber for treatment from storage. 1.4 Plan treating cycles in line with work order. |
2. Use equipment to treat timber | 2.1 Complete pre start-up equipment checks to ensure operational effectiveness. 2.2 Identify water requirements and check to ensure treatment process requirements are met. 2.3 Test moisture content of timber in line with organisational procedures. 2.4 Check, adjust and maintain strength of preservative solution at specified strength and volume. 2.5 Bring treating plant to full operating condition and regularly check operating parameters to ensure optimum output. 2.6 Load timber into treatment vessel and complete treatment cycles. 2.7 Brand treated timber in line with organisational procedures. 2.8 Safely handle treated timber and transfer to storage area. |
3. Complete operator maintenance | 3.1 Follow organisational safety procedures to lock out equipment. 3.2 Check all treatment mechanisms for effective condition. 3.3 Keep machine clear of dust and debris in line with organisational safety procedures. 3.4 Store chemicals in line with organisational safety procedures and report on stock levels. 3.5 Record and report timber treating process and equipment faults to appropriate personnel. |
