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 is covered under routine inspections? | Routine inspections may include water levels, water quality, colloids, salts and water supplies may also need to be tested for evidence of pathogens.Checks are made of medication tanks, drinker lines, filters, fogging systems, pumping systems, dams or town supplies as applicable. |
What water supplies may need to be monitored? | Water supplies may include rivers, dams, ponds, bores, tanks, town or mains water, and recycled water. |
What might be included in enterprise policy and procedures? | These may include operating manuals, recording and reporting requirements and OHS procedures for outdoor work such as protection from solar radiation, dust and noise, protection from drowning in rivers or dams and procedures for working at heights to monitor water levels in tanks. |
How might water need to be treated? | Where pathogens are found to be present, water should be sanitised before being provided to livestock. In line water medicators should be checked if applicable.Hand dosing of water supply may also be necessary. |
What information on water supplies may be recorded? | Information may include water levels, water quality problems such as presence of gross pollutants, oil and plant/algal growths, evidence of pathogens. |
What blockages might need to be cleared? | Blockages may be caused by vegetation overgrowth, sludge, animal carcasses and debris. |
What safe working procedures might be relevant to clearing blockages? | These might include the selection and use of relevant personal protective clothing and equipment, safe use of hand tools, relevant manual handling procedures, protection against contamination and safe disposal of materials causing pump blockages. |
What strainers are relevant to this standard? | Strainers include only those external to the pump.Livestock water supply systems may incorporate water filter systems which need to be regularly checked. |
What types of water delivery equipment may be relevant to this standard? | Water delivery equipment may include pumps types such as centrifugal, submersible, rotor, jet, diaphragm, piston, windmill and multi-stage centrifugal types, and axial flow. |
What OHS requirements relate to starting pumps? | OHS requirements may include procedures for prevention of electrical injury and protection of hearing, working outdoors, and working in confined spaces. |
