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 pressurised irrigation systems might be relevant to this standard? | Pressurised irrigation systems may include micro-irrigation systems and spray irrigation systems.Micro-irrigation systems may be mains pressure, low pressure, below or above ground, sprays systems, drip emitter trickle, t-tape, mini-sprinklers, and capillary.Spray irrigation systems may be travelling irrigators (soft hose, hard hose boom type), centre pivot, linear move, powered side roll hand shift permanent (installed), and bike shift/easy shift.Irrigation systems may range from manual operation and monitoring to fully automated with computer control and monitoring. |
What OHS requirements are relevant to this standard? | These may include systems and procedures for the safe operation of irrigation equipment and to ensure protection against injury when working with pressurised equipment, the prevention of electrical type injury, manual handling and procedures for working outdoors, including protection from solar radiation, dust and noise. |
What may need to be inspected? | This may include water flow, water quality and pressures at delivery points, lines for leaks and blocks, and drainage flow. |
What irrigation indicators might be relevant to this standard? | These may include soil moisture and plant/crop condition. |
What environmental considerations relate to this standard? | Environmental considerations may include efficient operation of the system to conserve water by identifying and repairing leaks, avoidance of over watering, and even distribution of water to targeted areas with minimal wastage and run-off. |
What might system components include? | These may vary according to brand and supplier and may include pumps, tensiometers, probe tubes, flow meter, catch cans, pressure gauge, computer and/or other scheduling devices, recycling equipment and spray equipment. |
What irrigation activities may be recorded? | These may include water used, time of shutdown, malfunctions, blockages, leaks and other faults requiring repair. |
