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. |
Relevantcompliance documentation may include: | legislative, organisational and site requirements and procedures manufacturer's guidelines and specifications Australian standards Employment and workplace relations legislation Equal Employment Opportunity and Disability Discrimination legislation |
Legislation may include Acts and regulations dealing with: | mining safety and health mine inspection OHS explosives |
Auxiliary equipment may be anything that is portable and mobile that is not part of the fixed infrastructure, and may include: | compressors distribution control systems (DCS) feeders gantry cranes and attachments and other mobile equipment hand and power tools hoses (water and air) |
Pre-start checks may include: | availability of equipment (e.g. conveyor) detection of conditions that are unusual fluid levels job requirements personnel availability walk through plant |
