Health and Safety Policy for Jet Washing and High-Pressure Cleaning Operations

This policy sets out the core principles that govern safe jet washing, pressure washing and power washing activities carried out by our teams. The purpose is to protect workers, bystanders and property by ensuring hazards are identified, controls are implemented and safe systems of work are followed. The policy applies to all personnel engaged in jet-cleaning tasks and those who plan, supervise or inspect such activities. It is essential that everyone understands their role and that safe equipment and methods are used at all times.

Scope and Responsibilities

This policy covers all high-pressure cleaning operations including surface cleaning, building façade washing and vehicle or plant cleaning. Management will provide resources and leadership to maintain safe pressure washing practices. Supervisors are responsible for risk assessment, authorising work and ensuring operatives are trained. Operatives must follow procedures, wear appropriate PPE and report hazards. Visitors and subcontractors must comply with site rules and co-operate with safety measures. Everyone has a duty to stop work if an unsafe condition arises and to seek guidance before continuing.

Hazard Identification and Risk Assessment

Prior to any jet washing task a documented risk assessment must be completed to evaluate potential risks such as slips, falls, water ingress, travel of spray, chemical exposure and equipment failure. The assessment should consider environmental factors, the condition of surfaces, proximity to people, electrical sources and confined spaces. Control measures are selected on the basis of the assessment and reviewed when conditions change. Typical hazards to consider include:

• High-pressure water injury and lacerations
• Chemical exposure from detergents or degreasers
• Falls from ladders, roofs or elevated platforms
• Electric shock from powered equipment or nearby supplies
• Environmental contamination and runoff

Control Measures and Safe Work Procedures

Controls for safe power washing and pressure cleaning include engineering and administrative measures and personal protective equipment. Engineering controls should be applied where possible and include using lower pressures for delicate surfaces, jet lances with safety nozzles, and barriers to isolate work areas. Administrative controls such as exclusion zones, permits for elevated work and job briefings reduce risk. PPE must be provided and used, including face shields, cut-resistant gloves, waterproof suits and non-slip footwear. Equipment must be inspected before use and maintained according to manufacturer guidance.

Training, Competence and Supervision

Personnel carrying out jet washing or high-pressure cleaning must be trained in safe operating techniques, hazard recognition and emergency response. Training should cover equipment setup, nozzle selection, chemical handling, and spill control. Supervision must be proportionate to the risk and competency of the operative. Records of training and competency checks are maintained and refresher training is provided when new equipment or methods are introduced. Only authorised and competent staff should operate high-pressure systems.

Safe systems of work for jet-cleaning operations should be written, communicated and displayed where appropriate. These systems include pre-start checks, method statements for complex tasks, and procedures for working at height or in confined spaces. Chemical safety data should be readily available and used to select appropriate PPE and neutralisation methods. Wastewater containment and disposal arrangements must be planned to prevent contamination of drains and waterways.

Emergency Preparedness and Incident Management

Emergency arrangements must be in place for high-pressure cleaning activities. First aid kits and trained first aiders should be available and emergency contact procedures are to be understood by the team. In the event of an injury, chemical splash or equipment failure, work must stop and help sought. Incidents, near misses and unsafe conditions should be reported promptly so that corrective actions can be taken. Investigations focus on root causes and prevention rather than blame.

Inspections and monitoring are essential to ensure ongoing safety in pressure washing and jet washing operations. Routine checks of hoses, couplings, nozzles and pumps reduce the likelihood of failures. Supervisors should undertake periodic audits of work sites and observe adherence to safe methods. Maintenance schedules and records for power washers and ancillary equipment form part of the safety management system, and equipment out-of-service must be clearly tagged until repaired.

Health, Environment and Continuous Improvement

Occupational health considerations include preventing prolonged vibration, repetitive strain and exposure to waterborne contaminants. Health surveillance is arranged where there is potential for significant exposure. Environmental protection is integral: contaminants and wash water must be controlled to prevent pollution, and biodegradable detergents are preferred where effective. This policy commits to continuous improvement through lessons learned, regular review, and stakeholder input. Management will review this policy periodically and when significant changes to jet washing methods or equipment occur.
