- On completion, remove tools and equipment, restore the work area, and report any incidents, near misses or changes in site conditions to the site supervisor.
- Complete the sign-off section at the end of this document before leaving site.
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.
Excavation Collapse Around the Tank Chamber
Control: Batter, shore or box excavations over 1.2m deep in line with a competent person's assessment, particularly around the larger open excavation required for a tank chamber.
Confined Space Entry for Connections & Inspection
Control: Never enter the tank chamber without a permit-to-work, atmosphere testing and a trained top-man in constant communication.
Manual Handling & Plant Interaction
Control: Use mechanical lifting for the tank itself, and keep operatives clear of the excavator's swing radius during placement.
Groundwater & Buoyancy Risk to the Tank
Control: Assess groundwater levels before installation and anchor or ballast the tank as specified by the manufacturer to prevent flotation.
Percolation Testing & Soakaway Siting
Control: Confirm percolation test results and soakaway siting distances from buildings, boundaries and watercourses in line with Building Regulations Part H before installation.
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 confined space entry into the tank chamber?
Yes. It includes a control prohibiting entry without a permit-to-work, atmosphere testing and a trained top-man, in line with the Confined Spaces Regulations 1997.
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.
