High Pressure Cleaner Risk Assessment

Product Overview

Identify and control organisational risks associated with High Pressure Cleaner operations through a structured, management-level WHS Risk Management approach that focuses on systems, planning, training, and equipment selection. This Risk Assessment supports compliance with the WHS Act, demonstrates Due Diligence, and helps protect your business from operational and legal liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Governance, Legal Compliance and WHS Consultation: Assessment of WHS governance structures, officer due diligence, consultation arrangements with workers, and alignment of policies with legislative requirements for high pressure cleaning activities.
  • Procurement, Design and Selection of Equipment: Management of risks associated with specifying, purchasing and introducing high pressure cleaners, including suitability of pressure ratings, guarding, hose and fitting integrity, and supplier documentation.
  • Competency, Training and Supervision Systems: Evaluation of competency requirements, induction content, refresher training programs, and supervision levels needed to safely manage high pressure cleaning operations.
  • Safe Work Procedures and Work Planning: Development and control of documented procedures, job planning processes, isolation and lock-out steps, and coordination of simultaneous operations involving high pressure cleaners.
  • Plant Maintenance, Inspection and Isolation Systems: Systems for scheduled inspection, testing and maintenance of pumps, hoses, lances and nozzles, including pre-start checks, defect reporting, tagging-out and isolation protocols.
  • Fuel, Energy and Environmental Management: Management of fuel storage and handling, electrical supply and leads, water usage, wastewater and overspray control, noise, and environmental protection obligations.
  • Traffic, Public Interface and Site Access Management: Controls for vehicle movements, pedestrian segregation, barricading, signage, and managing public exposure to high pressure cleaning activities in workplaces and public areas.
  • Personal Protective Equipment (PPE) and Health Monitoring Systems: Selection, issue and enforcement of appropriate PPE (e.g. eye, face, hand, foot and hearing protection, wet weather gear) and consideration of health monitoring where exposure risks are identified.
  • Emergency Preparedness and Incident Response: Planning for high pressure injection injuries, slips and falls, electrical shock, fuel or chemical spills, and ensuring first aid, communication and escalation procedures are in place and tested.
  • Audit, Monitoring and Continuous Improvement: Implementation of inspection checklists, performance metrics, incident trend analysis and management review processes to continually improve high pressure cleaner risk controls.

Who is this for?

This Risk Assessment is designed for Business Owners, Directors, Safety Managers and Supervisors responsible for planning, approving and overseeing High Pressure Cleaner operations across their organisation.

Hazards & Risks Covered

Hazard Risk Description
1. Governance, Legal Compliance and WHS Consultation

  • • Lack of clear organisational WHS policy and safety objectives specific to high pressure cleaning and ultra‑high pressure water‑blasting
  • • Inadequate consultation with workers and Health and Safety Representatives (HSRs) regarding high pressure cleaning risks in carparks, pathways, external walls and hard surfaces
  • • No formal process to review serious incidents, near misses or regulator alerts involving high pressure cleaners, hot water blasters and street cleaners
  • • Poor integration of WHS risk controls into business management systems, contracts and procurement decisions
  • • Inadequate change management when introducing new high pressure equipment, detergents, or demolition techniques
2. Procurement, Design and Selection of Equipment
  • • Procurement of high pressure cleaners, hot water blasters and ultra high pressure water‑blasting units that are not fit for purpose or non‑compliant with Australian Standards
  • • Selection of petrol‑powered pressure washers and hot jet street cleaners without considering ventilation, exhaust emissions and ignition sources
  • • High pressure hoses, guns, lances and fittings that are incompatible, poorly rated, or of low quality, increasing risk of hose burst, whipping or fitting failure
  • • Lack of engineered controls such as pressure relief valves, emergency shut‑offs, guards, hose restraints and gun trigger safety locks
  • • Insufficient noise, vibration and ergonomics consideration in equipment selection leading to long‑term health effects and fatigue
  • • Inadequate provision for safe transport, storage and handling of machines, fuels, detergents and wastewater containment accessories
  • • Failure to specify safety features for work in public carparks, pathways and external areas, such as lockable isolation, signage and traffic interface controls
3. Competency, Training and Supervision Systems
  • • Workers operating high pressure cleaners, hot water blasters and ultra high pressure demolition equipment without adequate training or verification of competency
  • • Supervisors lacking technical understanding of pressure cleaning hazards to enforce procedures and safe limits
  • • No formal induction specific to high pressure cleaning tasks in carparks, pathways, external walls and hard surface areas with public interface
  • • Inadequate training in emergency response, including dealing with injection injuries, electrical contact, chemical exposure and loss of control of hoses
  • • Failure to provide and enforce correct use of personal protective equipment (PPE) for different operating pressures, temperatures and cleaning chemicals
  • • Complacency or normalisation of deviance over time, leading to bypassing of controls such as guards, interlocks or isolation procedures
4. Safe Work Procedures and Work Planning
  • • Absence of documented safe work procedures (SWPs) or safe operating procedures (SOPs) for different types of pressure washing and water‑blasting tasks
  • • Inconsistent planning for high risk conditions such as working on wet, sloped or degraded concrete in carparks and pathways, or on elevated external walls and facades
  • • Inadequate assessment of proximity to electrical installations, live traffic areas, pedestrians, parked vehicles and other services before commencing work
  • • Failure to control simultaneous activities (e.g. other contractors, vehicle movement, public access) during pressure cleaning operations
  • • No formal process to assess weather, lighting, noise and environmental conditions that may affect high pressure work
  • • Poor definition of exclusion zones and barricading for ultra high pressure or hot water pressure cleaning where projectiles and spray can travel significant distances
5. Plant Maintenance, Inspection and Isolation Systems
  • • Degradation or failure of high pressure hoses, couplings, guns, lances and nozzles due to inadequate inspection, maintenance and replacement programs
  • • Failure of pressure relief devices, emergency stops or isolation valves from lack of testing or servicing
  • • Uncontrolled release of high pressure water or steam due to incorrect assembly, damaged fittings or makeshift repairs
  • • Use of pressure washers, hot water blasters or hot jet street cleaners with unreported defects, leaks, vibration or unusual noise
  • • No system for isolating and tagging out defective high pressure equipment, leading to continued unsafe use
  • • Over‑extended service life of critical components such as hoses operating beyond recommended hours or calendar life
6. Fuel, Energy and Environmental Management
  • • Uncontrolled storage and handling of petrol and other fuels for pressure cleaners, creating fire, explosion and environmental contamination risks
  • • Use of petrol‑powered pressure cleaners and hot jet units in partially enclosed carparks or near building intakes leading to carbon monoxide build‑up and fumes exposure
