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 government regulations, licensing and other compliance requirements may include: | biodiversity and genetically modified organisms biosecurity, translocation and quarantine business or workplace operations, policies and practices environmental hazard identification, risk assessment and control OHS hazard identification, risk assessment and control. |
OHS guidelines may include: | appropriate workplace provision of first aid kits and fire extinguishers clean, uncluttered, hygienic workplace codes of practice, regulations and/or guidance notes which may apply in a jurisdiction or industry sector enterprise-specific OHS procedures, policies or standards hazard and risk assessment of workplace, maintenance activities and control measures induction or training of staff, contractors and visitors in relevant OHS procedures and/or requirements to allow them to carry out their duties in a safe manner OHS training register safe lifting, carrying and handling techniques, including manual handling, and the handling and storage of hazardous substances safe systems and procedures for outdoor work, including protection from solar radiation, fall protection, confined space entry and the protection of people in the workplace systems and procedures for the safe maintenance of property, machinery and equipment, including hydraulics and exposed moving parts the appropriate use, maintenance and storage of PPE. |
ESD principles may include: | control of effluents, chemical residues, contaminants, wastes and pollution improving energy efficiency increasing use of renewable, recyclable and recoverable resources minimising noise, dust, light or odour emissions preventing live cultured or held organisms from escaping into environment reducing energy use reducing emissions of greenhouse gases reducing use of non-renewable resources undertaking environmental hazard identification, risk assessment and control undertaking facility quarantine, biosecurity and translocation of livestock and genetic material using and recycling of water, and maintaining water quality. |
PPE may include: | hard hat or protective head covering non-slip and waterproof boots (gumboots) or other safety footwear protective eyewear, glasses and face mask uniforms, overalls or protective clothing (e.g. mesh and waterproof aprons). |
