This document is provided as general guidance only and does not constitute legal, safety, or compliance advice. See the Important Notice at the end of this document.
This document provides guidance on pre-use and end-use checks for petrol and battery leaf blowers, handheld and backpack, used in grounds maintenance, estates, sports venue and local authority work. It covers equipment checks, operator safety considerations, and exposure obligations, and for blowers the exposure story has two strands of equal weight: hand-arm vibration through the handles, and noise, where petrol blowers are among the loudest tools in a grounds fleet and leaf season delivers some of its longest continuous running times.
For consistency, this document uses blower to refer to each individual machine. Checks described here are visual and operational only and do not replace inspection or servicing by a competent person. Where a defect involves the impeller, fan housing, throttle controls, or any safety-critical component, the blower should be assessed by a competent person before it is returned to service. If there is any doubt about a blower's safety at any point during a check, take it out of service until that assessment has happened. This guidance should be used alongside your organisation's site-specific risk assessments and safe working procedures, including any local arrangements on working hours and dust in public areas.
Vibration and Noise: The Long-Session Problem
Blowers rarely alarm anyone on paper: declared hand-arm magnitudes commonly sit between 1.5 and 4 m/s², modest by chainsaw standards. What the declared figure does not show is the duty cycle. Clearance work means long, near-continuous trigger time, hours of it in leaf season, so a modest magnitude multiplied by a long day still eats meaningfully into the exposure points budget, and a blower with a damaged impeller or perished mounts is no longer modest at all.
Noise is the blower's headline hazard. Petrol machines commonly run in the high 90s to over 105 dB(A) at the operator's ear, well above the upper action value of the Control of Noise at Work Regulations 2005, and the noise Regulations guide explains why at those levels unprotected exposure is measured in minutes and why the three-decibel doubling rule makes long blower sessions so costly. Hearing protection is not optional equipment on a petrol blower; it is part of the machine.
Exposure Action Value (EAV)
- Daily exposure: 2.5 m/s²
- At this level employers should take action to reduce exposure
- Health surveillance should be introduced
- Operators should be informed of the risks
Exposure Limit Value (ELV)
- Daily exposure: 5 m/s²
- This level should not be exceeded
- Exceeding this value is a breach of the Regulations
- Immediate action to reduce exposure is required
Tracking HAV exposure with Toolminder. Toolminder tracks hand-arm vibration exposure in real time as each blower is used, calculating cumulative daily exposure against the EAV and ELV thresholds and flagging with amber and red indicators when limits are approached or exceeded. Long blower sessions are exactly where live counting earns its keep. Reliable calculations depend on accurate, real-world vibration data for each blower. See the note below.
Vibration data: do not rely on manufacturer figures. The HSE advise that manufacturer quoted vibration values are typically measured under controlled conditions and are often not representative of real-world use. A blower's true magnitude also changes with the condition of its impeller and anti-vibration mounts. For accurate exposure calculations, vibration testing should be carried out on the actual blowers in use. Earlsmere offer vibration testing for grounds equipment. Contact Earlsmere for further information.
Pre-Use Check
A pre-use check should be completed each time a blower is brought into use. Where vibration exposure is tracked in Toolminder, the pre-use check is presented automatically before timing begins, so it is completed as part of starting work with the blower. Checks are typically completed in 2-3 minutes where no issues are found.
Operator training and authorisation. Everyone who uses a blower at work must have received adequate information, instruction and training under PUWER, covering safe operation, exposure management, and your organisation's rules on working near the public. Organisations should maintain records of training and authorisation, and only trained, authorised operators should complete these checks and use this equipment.
PPE Requirements
- Eye protection: safety glasses to EN 166: a blower's air jet lifts grit, dust, and debris into exactly the air the operator is standing in
- Hearing protection: mandatory on petrol blowers under the Control of Noise at Work Regulations 2005 given the levels involved, with ear defenders in good condition with intact seals, and worn for the whole session, not just the loud-feeling parts: noise exposure is cumulative across all equipment used that day
- Respiratory protection: in dry, dusty conditions, suitable dust protection in line with your risk assessment: a blower is a dust-raising machine by design, and the operator works inside the cloud
- High-visibility clothing: to EN ISO 20471 where work is on verges, near roads, or around moving plant and vehicles, in line with your organisation's site rules and risk assessment
- Gloves: work gloves for handling and for impeller access with the machine isolated. Anti-vibration gloves should not be relied upon as a control measure for HAV exposure: the HSE advise that their effectiveness against the vibration frequencies produced by this category of equipment is limited. Warm, dry hands are, however, genuinely less vulnerable to vibration injury
Do not use a blower with a safety-critical defect. Any blower with a cracked fan housing, a damaged or fouled impeller, missing intake guards, a throttle or cruise control that sticks or does not return, a stop switch that does not work, a backpack frame or harness with failed mounts or straps, or any fault that could affect operator safety or increase vibration output should be taken out of service and assessed by a competent person before further use.
Isolation Before Hands-On Checks
The hazard behind a blower's intake guard is a fan spinning at very high speed. Before any manual inspection, cleaning, or clearing of the impeller, tubes, or intake, the blower must be made incapable of running.
- On petrol blowers, the engine stopped and the spark plug lead disconnected before any access to the impeller or fan housing, however quick the clearance looks: fingers and an impeller must never be able to meet on a machine that could fire
- On battery blowers, the battery physically removed before any inspection, cleaning, or clearing: with the pack seated, a bumped trigger is all it takes for the fan to run
- Blowers taken out of service due to a safety-critical defect should be tagged or labelled clearly to prevent use by another operator, and physically separated from serviceable machines where possible, with a service job raised in Toolminder so the fault is formally recorded and tracked
Impeller, Housing & Tubes
The impeller is the blower's blade: it decides the machine's balance, its vibration, and what happens to anything drawn into the intake.
- Fan housing free of cracks and impact damage, with the intake guard or screen fitted, undamaged, and clear of packed leaf debris
- Impeller inspected through the guard, or per the handbook with the machine isolated: blades intact, with no chips, cracks, or debris wound around the shaft. A damaged or fouled impeller unbalances the machine, and imbalance at fan speeds becomes vibration at the handles immediately
- No rattle from the housing when the machine is gently tilted while isolated: a loose stone inside the fan case is both a vibration source and a projectile waiting for the outlet
- Blower tubes and nozzle secure, undamaged, and correctly latched: a tube working loose changes the machine's balance and thrust mid-session
- On vacuum-capable machines used in vacuum mode, the collection bag zipped, undamaged, and correctly fitted: the bag is part of the guarding between the impeller and the operator
Handles, Controls & Harness
- Handles secure, with anti-vibration mounts inspected for cracking, perishing, or separation: on backpack machines this includes the mounts isolating the engine from the frame, which are what keep the engine's vibration out of the operator's back and shoulders. A machine that suddenly buzzes through the frame has usually lost a mount
- Throttle returning freely, and any cruise control or throttle lock engaging and, more importantly, releasing cleanly: a throttle lock that sticks at speed removes the operator's quickest control
- Stop switch clearly marked and working
- On backpack machines, the harness webbing, stitching, buckles, and padding undamaged, with straps adjusting and holding: the harness carries the machine for hours, and its condition is a fatigue and posture matter as much as a comfort one
- All casings, covers, and fasteners present, secure, and undamaged
Power & Fuel
- On petrol blowers, correct two-stroke fuel mix per the handbook from fresh fuel, no fuel leaks, caps secure, and the air filter clean and correctly seated: blowers work in the dust they raise, so their filters clog faster than most, and a starved engine runs badly and hot
- Exhaust and its heat shield secure and undamaged, with the spark arrestor in place where fitted: on a backpack machine the silencer rides close to the operator's body, and a hot blower set down in dry leaves is an ignition source. Refuelling with the engine off and cooled, away from ignition sources, moving the blower away from the refuelling point before starting
- On battery blowers, the battery charged and correctly latched, with the casing free of cracks, swelling, or signs of water ingress and the terminals clean; spares stored per the manufacturer's guidance
Starting & Operational Check
- Blower started per the handbook on clear ground, with the outlet pointed away from people, animals, vehicles, and loose debris
- Starts cleanly, idles smoothly, and responds to the throttle without hesitation, with cruise control tested through engage and release
- No abnormal vibration at any speed: vibration that rises with fan speed points at the impeller, and stops work until the machine has been isolated and inspected
- Any failed task should prompt a reason for failure and supporting photos. Raise a service job immediately within the app
- Use the observations field to note early signs of wear, unusual vibration, or running issues
Work Area, Public & Dust
- Air jet never pointed at people or animals: the outlet stream carries grit at high velocity and can cause genuine eye and skin injury at close range, and this rule holds for colleagues as firmly as for the public
- Bystanders kept clear of the working area and the debris path, with work paused as people pass: on footpaths, around parked cars, and outside buildings, the considerate pause is also the safe one
- Debris directed away from roads, drains, and neighbouring property, and never blown into a live carriageway
- Dust managed in dry conditions: work with the wind rather than against it, consider damping down where practicable, and hold off around doorways, vents, and gatherings rather than fill them
- Noise managed as an exposure and a courtesy: the mobile hearing-protection principle from the noise Regulations guide applies, so colleagues working within the blower's radius wear protection too, and site or local rules on working hours near housing are respected
End-Use Check
An end-use check should be completed each time a blower is finished with and returned to storage. Where exposure is tracked in Toolminder, an end-use check can be configured to run automatically when the blower is stopped, closing the operator's usage record for that session, which is important for accurate HAV exposure tracking.
Cleaning & Condition
- Blower isolated before cleaning begins: engine stopped and spark plug lead disconnected on petrol machines, battery removed on battery machines
- Intake guard, cooling inlets, and fan housing cleared of packed leaves and debris: a blocked intake starves the fan and overheats the engine, and the end of a leaf-clearance day is exactly when it will be blocked
- Air filter checked and cleaned per the handbook, especially after dry, dusty work
- Casing, tubes, and harness wiped down, which is also the moment new damage gets noticed
Wear & Damage Review
- Impeller and housing condition reviewed for the next user, particularly after any ingestion rattle or vibration change during the session
- Anti-vibration and engine mounts re-checked after long sessions, along with harness condition on backpack machines
- Any new damage, leaks, or running issues recorded with notes and photos, with a service job raised if a fault needs attention before next use
Storage & Transport
- Fuel managed per the manufacturer's guidance for the expected storage period; batteries removed and stored per the handbook
- Blower stored dry and secure, never hot against dry leaves or other combustible material
- Transported secured, with tubes latched and the machine unable to shift or rest on its throttle
- Check saved to the asset history, with operator usage time recorded and visible to supervisors for HAV exposure monitoring
HAV Exposure: Operator Responsibilities
Operators using blowers should be aware of their cumulative daily vibration exposure and should report any symptoms of hand-arm vibration syndrome (HAVS), including tingling, numbness, or whitening of the fingers, to their supervisor immediately. Early reporting matters: HAVS is progressive, and symptoms become permanent if exposure continues without intervention.
The blower's risk is quiet accumulation. Sessions are long, the machine feels benign, and the points build anyway, on top of whatever the mower, trimmer, or brushcutter contributed earlier in the day. Cold-season clearance adds the familiar aggravator: cold, damp hands are more vulnerable to vibration injury, so warm, dry gloves and planned breaks from trigger time are part of doing the season properly.
Impeller condition is an exposure control. A chipped impeller blade, wound-on debris, or a stone rattling in the housing turns a low-vibration machine into a high-vibration one at fan speed, and on a tool run for hours at a stretch that change is expensive. Any increase in vibration beyond what is normally expected of a particular blower should be reported and the machine isolated and inspected before continued use.
Common Situations
All tasks pass
Mark each task as Pass, add any observations if relevant, and the check is complete. The blower is confirmed in good condition and ready for use. Plan the session's trigger time against the operator's remaining daily exposure budget, remembering that long clearance sessions draw it down steadily.
Rattle or new vibration from the fan housing
Stop and isolate the machine fully before investigating. The usual causes are a drawn-in stone or debris in the housing, material wound around the impeller shaft, or a chipped impeller blade, and all three are found with the machine isolated, never by peering into a running intake. Record the finding, clear or condemn as appropriate, and raise a service job in Toolminder if the impeller is damaged.
Throttle or cruise control sticks, or the stop switch fails
A blower that cannot be brought promptly under control is out of service immediately. Tag or physically separate the machine so it cannot be picked up in error, record the fault in Toolminder, and raise an urgent service job. Do not work around a sticking throttle for the rest of the day, however manageable it feels.
Working near the public on paths, car parks, or verges
Pause as people pass, keep the outlet and debris path directed away from them, and respect local arrangements on hours and dust. Where the public genuinely cannot be kept clear, your organisation's arrangements for the task apply. Record recurring pinch points in the observations so routes and timings can be planned rather than improvised.
Operator approaching daily limits across a long clearance day
If an operator's cumulative HAV exposure is approaching the EAV or ELV, or the day's noise dose is mounting across multiple loud tools, the work should be rotated to another trained operator. Record the session end in Toolminder so the exposure record is accurate. Supervisors can review operator usage across all assets, which matters most in leaf season, when the same few machines run all day.
Configuring Blowers in Toolminder
Toolminder can be configured with your organisation's blowers as individual assets, each with their own pre-use and end-use check templates covering the checks in this document. HAV exposure is tracked in real time as operators use each blower, with cumulative daily exposure calculated automatically across every tool used that day, which suits the blower's long-session profile particularly well. Accurate vibration data for each machine is essential for reliable exposure calculations, and blower magnitudes change meaningfully with impeller and mount condition. Earlsmere offer vibration testing for grounds equipment. Contact your Toolminder representative to discuss configuration and vibration testing for your fleet.
