Hazard & Risk Assessment
Each hazard is assessed against a standard Likelihood × Severity matrix. “Initial Risk” reflects the risk before any control measures are applied; “Residual Risk” reflects the risk once the stated controls are correctly implemented on site.
High-Pressure Water Jet Injury
Control: Never direct the jet at any person, and maintain a safe stand-off distance from the surface being cleaned in line with the equipment's rated pressure.
Exposure to Cleaning Chemicals & Biocides
Control: Follow the COSHH data sheet for all patio cleaners, algaecides and biocides used, and prevent run-off into drains or water courses.
Slips on Wet Surfaces During & After Cleaning
Control: Use warning signage around the work area and allow surfaces to dry before reopening to pedestrian traffic.
Damage to Vulnerable Surfaces & Pointing
Control: Adjust pressure and nozzle distance for the surface type, testing on an inconspicuous area first to avoid damaging soft pointing or block paving joints.
Working Near Electrical Fittings & Outdoor Sockets
Control: Identify and avoid directing the water jet at outdoor electrical fittings, sockets or lighting during cleaning.
Required PPE
Emergency Procedures
Fire
Stop work immediately, raise the alarm and evacuate to the designated assembly point. Do not attempt to fight a fire beyond your training. Call 999 once safely evacuated if the fire brigade has not already been alerted.
First Aid / Injury
Stop work and alert the nearest first aider or site supervisor. For a serious injury, call 999 immediately and do not move a casualty unless there is immediate danger.
Spillage / Environmental Incident
Stop work, contain the spill using the site's spill kit if safe to do so, and report it to the site supervisor immediately. Do not allow any spillage to enter a drain or watercourse.
Frequently Asked Questions
Does this RAMS cover the risk of chemical run-off into drains?
Yes. It includes a control requiring run-off from patio cleaners, algaecides and biocides to be prevented from entering drains or water courses, in line with COSHH and environmental good practice.
Do I need to keep a copy of this RAMS on site?
Yes. HSE guidance expects a copy of the RAMS — along with the completed sign-off section — to be available on site for the duration of the work, and reviewed if site conditions change.
