Range of VariablesThe Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available |
What pre-season maintenance might be carried out? | Pre-season maintenance may include removing scale in pipes, weed control in the system, removing sludge and living organisms, and repairing control devices. |
What post-season maintenance might be carried out? | Post-season maintenance may include draining supply system, draining and flushing diesel tanks of sediments, treating and flushing the system, capping open pipes on fixed systems, and covering fixed systems to protect from environmental degradation. |
What drainage systems might be relevant to this standard? | These may include surface drains, culverts, mole drains, sand slit, sub-surface traps, reed beds, pumps for recycling, and baffles. Systems may range from manual operation and monitoring to fully automated with computer control and monitoring. |
What components might be inspected and/or replaced? | These may include gutters, pipes, swales, subsurface pipes, gross pollutant traps, culverts, outfalls, and drainage materials such as rocks and gravels. |
What might the OHS requirements be for maintenance activities? | Requirements may include systems and procedures for safe manual handling, outdoor work (including protection from solar radiation, dust and noise), selection, use and maintenance of relevant personal protective clothing and equipment, selection, care and safe use of hand tools, and safe systems for the prevention of electrical injury. |
What might enterprise guidelines for weed control include? | Enterprise guidelines will identify OHS and environmental considerations. OHS requirements may include safe systems and procedures for the operation and maintenance of machinery and equipment, the handling, transporting, use and storage of farm chemicals, and protection against chemical residues, including that in/on foliage, water, soil and other items.Environmental considerations may include choice of chemical versus mechanical weed control/removal, use of hand versus powered equipment, and procedures for avoiding chemical contamination of water supplies. |
