Understand the Risks Before You Start
A pressure washer can:
✔ Cut skin and cause serious injury
✔ Strip paint, damage wood and crack paving
✔ Send debris flying at high speed
✔ Knock you off balance on wet surfaces
Treat a pressure washer with the same respect you would any powered tool.
Wear the Right Safety Gear
Before switching on, always wear:
✔ Eye protection — flying grit and debris are common
✔ Sturdy footwear — non-slip shoes or boots
✔ Gloves — improves grip and control
✔ Long trousers — protects legs from spray and debris
Never use a pressure washer in sandals or barefoot.
Use the Correct Nozzle and Pressure Setting
Incorrect nozzle choice is a major cause of damage and injury.
✔ Start with a wide fan nozzle
✔ Avoid pencil or turbo nozzles unless needed
✔ Increase pressure gradually — never start at maximum
✔ Use low pressure on cars, decking and painted surfaces
High pressure is not always better.
Keep a Safe Distance
✔ Start 30–45 cm away from the surface
✔ Move closer only if necessary
✔ Never point the lance at people, pets or yourself
✔ Never test spray on your hand or foot
Even brief contact with high-pressure water can break skin.
Maintain a Stable Stance
Pressure washers produce strong kickback.
✔ Stand with feet shoulder-width apart
✔ Keep both hands on the lance
✔ Avoid leaning over edges or steps
✔ Be extra careful on wet patios and slopes
Loss of balance is a common cause of falls.
Be Careful Around Electrical Hazards
✔ Keep plugs and extension leads dry
✔ Use outdoor-rated extension cables only
✔ Avoid standing in puddles
✔ Never spray electrical fittings, sockets or lights
Electric shock is a real risk if water reaches power sources.
Never Run the Washer Dry
✔ Always turn on the water supply first
✔ Hold the trigger before starting the motor
✔ Shut off the machine before turning off the tap
Running dry damages the pump and increases failure risk.
Avoid Fragile Areas and Surfaces
Never pressure wash:
❌ Loose pointing or cracked paving
❌ Old or damaged wood
❌ Roof tiles or felt
❌ Windows, seals or vents
Use a soft brush or low-pressure wash instead.
Keep Children and Pets Away
✔ Keep a safe working area
✔ Never leave the machine running unattended
✔ Store the washer securely after use
High-pressure spray and hoses are dangerous distractions.
Take Breaks and Avoid Fatigue
✔ Don’t rush large jobs
✔ Take regular breaks
✔ Stop if your grip weakens or arms tire
Fatigue leads to loss of control.
Shut Down Safely After Use
✔ Switch off the motor
✔ Release pressure via the trigger
✔ Disconnect hoses and power
✔ Store equipment safely and dry
Proper shutdown prevents accidental spray and damage.
Final Thoughts
Pressure washers are incredibly effective — but only when used safely. Most accidents happen when users rush, ignore basic precautions or use too much pressure.
By wearing proper protection, choosing the right settings and staying aware of your surroundings, you can clean patios, paths, cars and outdoor spaces efficiently and safely.
A pressure washer should save you time — not send you to A&E.
