Hazards & Risks Covered

Hazard	Risk Description
1. WHS Governance, Roles and Consultation	• Lack of clearly defined WHS responsibilities for irrigation projects • Inadequate consultation with workers and subcontractors on site‑specific irrigation risks • Insufficient WHS planning for simultaneous landscaping and irrigation works • Failure to integrate WHS Act 2011 due diligence duties into project decision‑making • Poor communication of WHS expectations to small contractors and seasonal workers • No formal process for raising and resolving WHS concerns related to irrigation works
2. Project Planning, Design and Engineering of Irrigation Systems	• Irrigation system design not considering WHS implications (e.g. unsafe access, high‑pressure lines, manual handling loads) • Poor coordination between designers, engineers and installers leading to unsafe construction methods • Inadequate consideration of soil stability and trench design for ditches and pipe runs • Failure to identify existing services in design stage, increasing risk of strike during excavation • Design choices that necessitate ongoing high‑risk maintenance activities (e.g. valves in confined or unstable locations)
3. Contractor, Subcontractor and Labour Hire Management	• Engagement of irrigation contractors without verification of WHS competency or licences • Poor coordination between multiple subcontractors (irrigation, landscaping, civil works) leading to uncontrolled interaction risks • Inadequate supervision of inexperienced labourers during ditching and repair works • Labour hire workers not inducted into site‑specific irrigation and excavation hazards • Inconsistent safety standards across different contractors on the same project
4. Training, Competency and Supervision for Irrigation Works	• Workers performing irrigation installation or repairs without adequate training in WHS requirements • Insufficient competency in trenching, shoring and working around underground services • Lack of understanding of hydraulic hazards (pressure, stored energy, water hammer) • Inadequate supervision of apprentices and new starters on landscaping irrigation projects • No verification of plant operator competencies for trenchers, excavators or compactors
5. Plant, Equipment and Tool Management for Irrigation and Ditching	• Use of uninspected or poorly maintained trenchers, excavators, compactors and pumps • Failure of hoses, couplings or fittings under pressure during irrigation testing • Uncontrolled interaction of mobile plant with workers in excavation areas • Inappropriate tools used for cutting pipes or fittings, increasing risk of lacerations and eye injuries • Lack of system for managing defective equipment and removing it from service
6. Excavation, Trenching and Ground Stability Management	• Collapse of irrigation ditches and trenches due to unstable or waterlogged soils • Uncontrolled access to open excavations by workers or public (especially in landscaped public areas) • Inadequate systems for assessing trench depth, battering and shoring requirements • Failure to manage spoil placement leading to surcharge on trench edges • Ingress of surface water increasing risk of slip, trip and drowning in deeper excavations
7. Underground and Overhead Services Management	• Striking underground electrical, gas, water, communications or sewer lines during ditching • Contact of plant or irrigation materials with overhead powerlines during installation • Inaccurate or outdated services plans leading to false sense of security • Lack of a systematic approach to locating and positively identifying services • Uncontrolled work in easements with multiple third‑party asset owners
8. Water, Pressure and Pump System Safety	• Uncontrolled release of high‑pressure water during testing, flushing or commissioning of irrigation lines • Failure of pumps, valves or fittings resulting in hose whip or component ejection • Backflow contamination into potable water supplies due to inadequate backflow prevention systems • Working on live or partially isolated irrigation systems • Stored energy hazards in pressure vessels, accumulators or elevated storage tanks
9. Environmental Conditions, Site Layout and Public Interface	• Heat stress, UV exposure and dehydration during outdoor irrigation and landscaping works • Slips, trips and falls due to uneven ground, open ditches and temporary irrigation lines • Uncontrolled access by members of the public to active irrigation installation areas, particularly in parks or commercial landscapes • Adverse weather (rain, storms, flooding) affecting trench stability and electrical safety of pumps • Poor site layout leading to vehicle‑pedestrian conflict around material laydowns and watering equipment
