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. |

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 |
