Power flushing, Unit 3, Canal Side Business Park, Stockport
Risk assessment
People entering the work area or tripping over materials
Workers, occupants and visitors
Mark or barrier the active work area. Store tools and materials away from access routes.
Flushing exposes a leak and causes water damage
Heating workers and building occupants
Record the condition before work. Stop if the system is not suitable for flushing.
Electric shock, hot water or uncontrolled flow
Heating workers and occupants
Use the planned isolation. Prove the system is safe before opening it.
Dirty or treated water floods the building or reaches the wrong drain
Heating workers, occupants and the environment
Do not start without an agreed route. Keep people away from the discharge water.
Sludge, leaks or uncontrolled discharge during flushing
Heating workers and occupants
Watch the hoses, connections and system while flushing. Stop if a leak or unsafe pressure appears.
Cleaner or sludge remains in the heating system
Heating workers and occupants
Follow the machine and product instructions. Use only the agreed discharge route.
Debris, tools or unfinished work left in the area
Workers, occupants and visitors
Remove waste by the agreed route. Record and protect any unfinished work.

Method statement
- 1Set up the work areaConfirm the work area and scope before starting. Keep other people outside the active work area. Keep entrances and escape routes clear.
- 2Check the system before flushingInspect for heavy sludge, corrosion and signs of leaks before connecting the machine. Explain that cleaning can expose leaks in badly corroded parts.
- 3Isolate the heating systemTurn off the electrical controls and isolate the system before connecting the flushing machine. Let hot water cool before opening the system.
- 4Set up the discharge routeConnect the dump pipe to the agreed waste drain or contained tank. Check the route, hose joints and spill control before starting.
- 5Run the initial flushTurn on the power-flushing unit to remove the system water. Refill with fresh water and dose this job's cleaner as its instructions say.
- 6Flush until the water is clearContinue dynamic flushing with mains water until the discharge is clear. Disconnect the machine safely when the flush is complete.
- 7Clear and hand back the areaRemove tools, waste and unused materials. Check the area is clean and ready to use. Tell the customer or whoever runs the site when the work is complete.
What a power flushing RAMS covers
Pumping water and cleaning chemicals through a radiator system to shift sludge and scale, then adding inhibitor. Not covered: sealed commercial heating or chilled loops.
- Heating system flush
- Chemical treatment
Suggested steps and hazards for power flushing
Suggested for heating system flush before any questions are answered.
Check the system before flushing
- Inspect for heavy sludge, corrosion and signs of leaks before connecting the machine.
- Explain that cleaning can expose leaks in badly corroded parts.
Hazard
Flushing exposes a leak and causes water damage
Who might be harmed and how
Heating workers and building occupants
Controls in place
- Record the condition before work.
- Stop if the system is not suitable for flushing.
A condition check finds weak parts before pressure and flow expose them.
Powerflushing Isolate the heating system
- Turn off the electrical controls and isolate the system before connecting the flushing machine.
- Let hot water cool before opening the system.
Hazard
Electric shock, hot water or uncontrolled flow
Who might be harmed and how
Heating workers and occupants
Controls in place
- Use the planned isolation.
- Prove the system is safe before opening it.
Isolation controls electrical energy, hot water and flow before the machine is connected.
Powerflushing Set up the discharge route
- Connect the dump pipe to the agreed waste drain or contained tank.
- Check the route, hose joints and spill control before starting.
Hazard
Dirty or treated water floods the building or reaches the wrong drain
Who might be harmed and how
Heating workers, occupants and the environment
Controls in place
- Do not start without an agreed route.
- Keep people away from the discharge water.
A checked route keeps flush water under control from the first discharge.

- What chemical is specified?
- Which parts will you flush?
- What is in the heating system?
Where
- Where will the flush water go?
How it’s done
- What will you stand on to reach the work?
- How will you check the treatment?

What the law asks for
What a RAMS is
A risk assessment and method statement. The risk assessment records what could cause harm on the job, who could be harmed and how, and the controls that keep the risk down. The method statement sets out how the work will be done, step by step, in the order it happens.
A client or main contractor will usually ask for one before you start. RAMS is a site term, not a legal one: the law asks for the risk assessment and for the work to be planned, and a method statement is the usual way to show that plan for one job.
What the law asks for
- Employers, and self-employed people doing construction work, must make a suitable and sufficient assessment of the risks to their own people and to anyone else affected by the work (Management of Health and Safety at Work Regulations 1999, regulation 3).
- An employer with five or more employees must record the significant findings and any group of employees it finds especially at risk. The assessment must be reviewed if there is reason to think it is no longer valid, or the work has changed significantly.
- Every contractor must plan, manage and monitor its work so that, so far as is reasonably practicable, it is done without risks to health and safety, and must give its workers the information and instructions they need, including the hazards the risk assessment found (Construction (Design and Management) Regulations 2015, regulation 15).
HSE guidance: the steps to manage risk and what contractors must do under CDM. This is the law in Great Britain; Northern Ireland has its own equivalent regulations.
What the builder does
You choose the work and answer questions about how the job will be done, such as what you will stand on and what else is going on nearby. Your answers decide which steps, hazards and controls it suggests.
Many suggestions link to the HSE guidance they draw on. Your work is kept in this browser and, signed in, on your account with its photos; the PDF is made on your device. A briefing you send to phones goes through your account.
Separate documents
A COSHH assessment, lifting plan, permit to work, asbestos survey and the principal contractor’s construction phase plan are separate from the RAMS.
Reviewing a RAMS before work starts
RAMS review reads a RAMS PDF, yours before you send it or one a subcontractor sends you, and lists the points to raise, each marked on the page it comes from. Quick reviews are free.
