Health & Safety Policy for Pressure Washing Services
This Health & Safety policy sets out the approach our gardening and grounds maintenance teams take when delivering pressure washing services and associated exterior cleaning. The aim is to protect staff, clients, the public and the environment during all forms of surface cleaning, from high-pressure power washing to gentler soft wash and jet wash techniques. The policy applies to scheduled maintenance, one-off restorations, driveway cleaning and routine pressure-cleaning tasks across our service area.
Our commitment is to maintain safe systems of work and to ensure that every operative understands risk controls for pressure washing, power washing and related external cleaning operations. The policy is intended to be practical for field crews working alongside planting and landscaping activities and for supervisors planning site work. It does not replace specific method statements or dynamic risk assessments produced for complex jobs.
Responsibilities are clearly allocated: management must ensure safe equipment, training and oversight; supervisors must confirm site controls and documentation; operatives must follow procedures and report hazards. Key duties include:
- Pre-job risk assessment and permit-to-work where needed
- Provision and correct use of personal protective equipment
- Maintenance of pumps, hoses and nozzles to manufacturer standards
Risk Assessment and Planning
Each pressure cleaning task requires a documented risk assessment identifying hazards such as slips, contact with moving parts, chemical exposure, noise and flying debris. Planning must consider surface type, adjacent planting, irrigation systems and nearby footpaths or roads. Wherever possible a soft wash approach should be used on fragile masonry, timber or upholstery to avoid damage while still delivering effective cleaning.Control measures must be proportionate to the hazard. Use appropriate nozzle sizes, pressure settings and safe distances when using jet washing or power washer equipment. Isolation of utilities, consideration of electrical equipment, and temporary diversion of pedestrians are routine controls. Supervisors should ensure a written method statement is available for complex façades or elevated work.
Equipment, Inspection and PPE
All pressure washers, boilers, hoses and consumer chemical containers must be inspected before use and maintained under a scheduled programme. Operatives must wear suitable PPE: eye protection, waterproof gloves, non-slip boots, hearing protection and, where chemical agents are used, chemical-resistant aprons and respirators. It is essential that equipment guards are in place and that staff understand lock-off procedures before cleaning or maintenance.Chemical Use and Environmental Controls
Chemicals and detergents used for cleaning should be chosen for efficacy and biodegradability. Store hazardous substances in labelled containers and follow the manufacturer's directions. Minimise run-off with absorbent booms, drains blocked with containment plugs, and by collecting wash water where practical. Protect planted areas and wildlife from contamination by using targeted application and rinsing procedures that prevent chemical ingress to soil and watercourses.Waste and rinse water should be disposed of responsibly; where collection is not feasible, you must use approved containment and neutralisation techniques to prevent pollution. Avoid overuse of surfactants and avoid mixing products. A conservative approach to chemical concentration is both safer and often more sustainable.
Traffic, Public Safety and Site Controls
On streets, pavements and communal spaces, implement clear exclusion zones with cones, tape and signage to separate the working area from the public. Assign a banksman or operative to supervise pedestrian flow for larger jobs. When operating near vehicles or cycle lanes, use high-visibility clothing and ensure pressure equipment is positioned to avoid trip hazards. Keep a basic first-aid kit and spill kit on site at all times.Working at Height and Access
When façade cleaning requires ladders, mobile elevating work platforms or scaffolding, comply with safe systems for working at height. Assess stability of surfaces before positioning ladders and never exceed recommended reach while operating a pressure washer. Consider alternative methods such as telescopic low-pressure systems to avoid unnecessary exposure to heights.
Training, Competence and Supervision
All operatives must receive training in the safe use of pressure washing equipment, chemical handling and emergency procedures. Training should cover different cleaning techniques including power wash and jet wash methods, plus competency assessments and refresher sessions. Supervisors are responsible for ensuring staff are signed off for the specific equipment they will operate and that on-the-job coaching is provided.
