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. |
Relevant compliance documentation may include: | legislative, organisational and site requirements and proceduresmanufacturer's guidelines and specificationsAustralian standardsEmployment and workplace relations legislationEqual Employment Opportunity and Disability Discrimination legislation |
Outburst mining management plans establish procedures for maintaining a safe environment including: | hazard identification and quantificationrisk assessmentauthority and responsibilitycontrols established to manage identified risksreporting and communicationdocument control audit and review |
Actions (alarm or trigger) level is a generic term used to describe a level determined at the mine site at which action is initiated or a response made. | |
Audit is the validation process to ensure the system, procedures, processes meet the established objectives and are implemented. | |
Risk is defined as: the chance of something happening that will have an impact upon objectives. It is measured in terms of consequences and likelihood (definition from AS/NZS 4360:1999 Risk Management). | |
Hazard is defined as: a source of potential harm or a situation with a potential to cause loss (definition from AS/NZS 4360:1999 Risk Management). | |
