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 particular training and assessment requirements may depend on the work situations available |
What OHS hazards may be associated with tending nursery plants? | Hazards may include the use of chemicals and hazardous substances, sharp tools, manual handling, solar radiation and operating spray equipment. |
What areas may be considered part of the nursery environment? | The nursery environment may include glasshouses, shade houses and hardening-off areas. |
What is covered by plant growth and health requirements? | Plant growth requirements may include watering, light levels, fertiliser regime, pruning and shaping, repotting, and staking. |
What types of irrigation system may be relevant to this standard? | Irrigation systems may include ebb and flow, sprinklers, capillary beds, sprayers and drippers. |
What irrigation system components may require servicing? | Irrigation system components may include pumps, lines, pipes, sprinklers, sprinkler heads, solenoids, filters, controllers, sprayers and drippers. |
What performance parameters should be checked to ensure the effective operation of the irrigation system? | Checks may include identifying dry spots and blockages, water dumping, abnormal water flow, and leaking heads, lines and pipes. |
What nursery hygiene practices should be considered when tending plants? | Hygiene practices may include removing weeds, dead or diseased plant material; washing the work area on transfer of plants; disinfecting tools, equipment and work areas, and using foot baths on entry to different work areas. |
What personal protective equipment (PPE) may be required to tend nursery plants? | Personal protective equipment may include hat, boots, overalls, gloves, sunscreen lotion, goggles, face mask, respirator, spray jacket or suit. |
What common problems may be encountered during plant maintenance operations? | Common problems may include dehydration, pests, diseases, nutrient deficiencies and deformed plants. |
What types of nursery plants may be relevant to this standard? | Nursery plants may include containerised, balled and bagged, in-ground, aquatic, stock plants, cuttings and rootlings. |
What tools and equipment are likely to be used for plant maintenance? | Tools and equipment may include secateurs, water spray containers, dibblers, sprayers, plant supports, ties and rubbish bins. |
What treatments are likely to be selected and applied to nursery plants? | Treatments may include pesticides, fungicides, fertiliser, mulching, removing weeds, removing dead material, tip pruning, formative pruning, aeration, staking, tying, spacing and thinning. |
What methods may be used to apply water to nursery plants? | Water may be applied manually or by operating the irrigation system. |
What enterprise work procedures may apply to this standard? | Work procedures will be based on sound horticultural principles and practices and may include supervisors oral or written instructions, the Nursery Industry Accreditation Scheme, plant care program, enterprise standard operating procedures (SOPs), specifications, production schedules, routine maintenance schedules, work notes, product labels, and Material Safety Data Sheets (MSDSs); Integrated Pest Management (IPM) programs; manufacturers service specifications and operators manuals; waste disposal, recycling and re-use guidelines; and OHS procedures. |
What OHS requirements may be relevant to this standard? | OHS requirements may include identifying hazards, assessing and reporting risks, cleaning, maintaining and storing tools and equipment, appropriate use of personal protective equipment including sun protection, safe operation of tools and equipment, safe handling, use and storage of chemicals and hazardous substances, correct manual handling, basic first aid, personal hygiene and reporting problems to supervisors. |
What workplace information is likely to be recorded? | Records may include environmental parameters, date of treatments, type of treatment and rate of treatment. |
What type of waste may be collected? | Waste may include left over treatments, unused containers, plant debris or faulty irrigation components. |
What are the implications for the external environment when performing this unit? | Environmental implications may include the contamination of off-site ground water or soils from solids, nursery debris, nutrients or chemicals. |
