The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |

Work order is to include: | instructions for the drying of timber and may include: species colour type width length thickness quantity target moisture content instructions for the environmental monitoring of work and procedures environmental care requirements relevant to the work |
Appropriate personnel may include: | supervisors suppliers clients colleagues managers |
Drying | is the process of removing water from timber whilst minimising degrade until it reaches a target moisture content suitable for intended use |
Conversion process may include: | sawing process yard storage shed or other kiln storage delivery of material to the kiln site |
Racks | are packets of timber with racking sticks between each row of boards to facilitate evaporation of water from the timber |
Visual assessment is to include: | the assessment of materials to determine stacking quality and faults and may include: stability squareness of ends spacing of strips support to minimise warping |
Equipment must include: | solar assisted kilns procedures for equipment lock-out and safe entry, i.e. protecting operators and co-workers from accidental injury by isolating the machinery from the power source and may include: supplementary heat plant forklift or loader traverser and trolley |
Sample Boards | are boards selected to be used to monitor moisture loss during the drying process |
Moisture content | is the amount of moisture in timber at any given time and must include: assessment via capacitance, resistance and oven-dry methods |
Drying plan | is the anticipated process the timber will undergo to remove moisture to target moisture content and may include: air drying sheltered air drying pre-drying reconditioning high humidity treatments final kiln drying equalising conditioning |
Communication may include: | verbal and non-verbal language constructive feedback active listening questioning to clarify and confirm understanding use of positive, confident and cooperative language electronic alarm, alert and notification systems associated with the kiln control software |
Pre start-up checks | are conducted to ensure equipment has been set-up correctly, the systems are performing accurately and equipment is operating to optimum performance |
Emergency shutdown | is the immediate shutting off of the equipment to prevent an accident or prevent damage to the machine or product |
Kiln | See equipment |
Baffles and/or blankets | are to assist in the drying process by directing air flow |
Drying schedule | is the drying set points based on moisture content, moisture loss or time |
Drying degrade may include: | surface checks internal checks end splits collapse excessive distortion bow spring twist cup case Hardening |
Drying end point | is the point in time when the drying process will be completed and the target moisture content achieved |
Target moisture content | is the moisture content the kiln operator is trying to obtain from any given batch of timber |
Drying stresses | are stress levels that develop through the drying process likely to affect timber performance in service |
Rectified | refers to the amelioration of excessive drying stresses and may include: high humidity treatments conditioning re-drying letting timber equalise |
Sub-standard material | See drying degrade |
Disposal may include: | processing to a lower grade of product recovery of heat value recovery as ungraded product |
Moisture probes | are probes pierced into representative boards which provide moisture readings to assist in monitoring the drying schedule and may include resistance or electromagnetic property probes |
