Hedge Trimming and Garden Maintenance
Regular garden maintenance activities including powered hedge trimmer operation, lawn mowing (push and ride-on), line trimming/whipper snipping, leaf blowing, garden bed weeding and mulching, shrub pruning with secateurs and loppers, and green waste removal. Covers powered equipment operation, hazard controls for flying debris and eye injuries from line trimmers (cutting-head tip speed at full RPM is in the order of hundreds of km/h), noise exposure from multiple tools (hedge trimmer 90-100 dB(A), ride-on mower 90-100 dB(A), line trimmer 95-105 dB(A), leaf blower 85-100 dB(A)), manual handling of heavy equipment and green waste (bags 15-25kg), repetitive overhead work for hedge trimming causing musculoskeletal strain, UV and heat exposure from full-day outdoor work, and chemical handling for herbicides and fertilisers. Work may involve ladder access for tall hedges, operation near public roads and traffic, and possible contact with toxic ornamental plants (oleander, euphorbia, dieffenbachia) where applicable. Pre-filled hazards, controls, and risk ratings.
A line trimmer's nylon cord whips at speeds fast enough to launch a small stone through a parked car window, and the public-liability claim that follows is the recurring cost line on a domestic garden round. A 15-metre exclusion zone with a visual sweep of the work area before pulling the cord is the practical control; the operator who hits a metal edging or a brass sprinkler with the head running is creating a projectile they didn't plan for. Eye protection to AS/NZS 1337.1:2010 — full safety glasses or a face shield, not sunglasses — covers the operator's side.
The cumulative noise picture is what catches the trade legally. A garden maintenance day routinely runs hedge trimmer (90-100 dB(A)), line trimmer (95-105), blower (85-100) and ride-on mower (90-100) across the same 8 hours, and the daily noise dose under the Model Code of Practice on Managing Noise and Preventing Hearing Loss sits well above the threshold. Class 5 muffs to AS/NZS 1270:2002 as the default rather than the upgrade, and double protection (plugs plus muffs) on the line trimmer in particular.
Where chemical spraying enters the round — knapsack glyphosate on a path, a spot-spray on a driveway weed — wind condition, nozzle pressure and a logbook entry shift the work into APVMA spray drift territory. Drift onto a neighbour's vegetable garden is the recurring complaint trigger that turns a routine hedge job into a council inquiry. Snake encounters in long grass through summer, ladder use for tall hedges with the Working at Heights Code of Practice governing the upper-storey reach, and an SPF 50+ regime on full-day exposure round out the daily call. Walk before trim, hearing on, drift checked — three habits per house.
What's In Your SWMS
7 Hazards & Controls
Corneal abrasion or perforation, retinal damage, hyphema (blood in anterior chamber), lens dislocation, permanent vision loss or blindness, orbital compartment syndrome, facial lacerations and bruising
Use pre-edged paving/paths instead of line trimming edges. Use mulch bed borders instead of requiring constant line trimming at obstacles.
Use manual edging tools (spade, edge trimmer) instead of powered line trimmer for small areas. Use ride-on mower instead of line trimmer where possible.
Establish exclusion zone 5m radius from line trimmer operation. Keep other workers and public at least 10m away. Use barriers/cones if work near public areas.
- Hedge trimmer with integrated cutting head guard designed to deflect debris away from operator (guards must be present and functional)
- Line trimmer guard sized to catch and contain stones (minimum 50mm guard around cutting head)
- Full face shield or visor integrated into helmet - polycarbonate or glass minimum 2mm thickness
- Leaf blower with deflector to direct discharge away from people
- Cutting head spinning at controlled speed (not exceeding manufacturer specs) - overspinning increases projectile velocity
- Pre-operation inspection: check guard integrity, cutting head alignment, and blade condition before each use
- Operator scan protocol: scan work area for rocks, sticks, loose debris BEFORE starting equipment. Remove larger stones/debris manually
- Operator position: stand at 90-degree angle to cutting head, never directly in line with discharge
- Never point line trimmer toward people, property, or vehicles
- Keep bystanders minimum 10m away during operation - enforce perimeter
- Use line trimmer on lower speed settings for edge trimming (reduces projectile velocity by 20-30%)
- Inspect cutting line condition - dull or damaged line increases debris generation
- Do NOT use line trimmer near windows, parked vehicles, or pedestrians - position yourself to prevent ricochet
Safety glasses or full face shield (AS/NZS 1337.1:2010) MANDATORY for all line trimmer and hedge trimmer operation. Full-coverage face shield strongly preferred over glasses alone.
16-Step Work Procedure
Equipment & PPE
Equipment (11)
- Powered hedge trimmer (petrol, electric, or battery)
Petrol 20-25cc or electric 80-120V. Double-sided cutting blades for efficient operation. Regular inspection of blade sharpness, alignment, and safety switches. Maintain 600mm clearance from body. Never attempt to clear jammed material with trimmer running.
- Push lawn mower (petrol or electric)
For residential lawns and accessible areas. Maintain sharp blades. Ensure grass catcher or mulch function is working. Never reach into discharge area.
- Line trimmer/whipper snipper (petrol or electric)
Petrol 20-25cc or electric 80V+. Nylon cutting line fires at high velocity (300+ km/h). Regular inspection of cutting head, line condition, and guard integrity. Replace cutting line when worn. Never use metal blade on line trimmer.
- Leaf blower (petrol or electric)
Handheld or backpack mounted. 80+ km/h wind velocity can propel stones. Keep air discharge away from people and windows. Check air intake filter regularly.
- Secateurs and hand pruning shears
For cutting branches up to 10mm diameter. Maintain sharp blades. Use bypass-type secateurs for clean cuts. Check handles for cracks or looseness.
- Loppers and long-handled pruning shears
For branches 10-20mm diameter. Lever action provides mechanical advantage. Maintain sharp blades and check joint pin/pivot for wear.
- Hand pruning saw (folding)
For branches over 20mm diameter. Maintain sharp blade. Secure in holster when not in use.
- Wheelbarrow (heavy-duty, pneumatic tyres)
For transporting green waste to collection point. Check tyre pressure before use. Pneumatic tyres handle uneven ground better.
- Garden rake and broom
For collecting leaves, debris, and grass clippings. For final cleanup of hard surfaces.
- Green waste collection bags or large bins
For collecting trimmed hedge material and grass clippings. Heavy-duty bags rated for mulch/waste. Label bags with contents for appropriate disposal.
- First aid kit (comprehensive)
Include eye wash bottle (critical for debris eye injuries), sterile gauze/dressings, compression bandages, tweezers for splinter removal, burn treatment, sunburn relief supplies.
PPE (7)
- Safety glasses or face shieldAS/NZS 1337.1:2010
CRITICAL for line trimmer and hedge trimmer operation. Flying stones and twigs from line trimmers are a leading cause of eye injuries in garden maintenance. Impact-resistant polycarbonate with UV protection. Anti-fog coating recommended. Full face shield preferred if doing heavy line trimming.
- Hearing protection (Class 5 for power equipment)AS/NZS 1270:2002
Multiple equipment exposure: hedge trimmer 90-100 dB(A), ride-on mower 90-100 dB(A), push mower 85-95 dB(A), line trimmer 95-105 dB(A), leaf blower 85-100 dB(A). Daily exposure commonly exceeds the 85 dB(A) LAeq,8h exposure standard, making cumulative damage risk HIGH. Earmuffs or custom-moulded earplugs. Ensure proper fit and seal throughout work day.
- Safety boots (steel cap, non-slip sole)AS 2210.3:2019
Steel cap for protection from dropped tools and equipment. Non-slip sole essential for wet grass or slippery surfaces. Oil-resistant sole for handling petrol equipment. Note: AS 2210.3 is now AS-only (Australia-only re-designation).
- Work gloves (cut/abrasion resistant; vibration-damped where used with vibrating tools)AS/NZS 2161.1:2016 (general); AS/NZS 2161.3:2020 (mechanical/cut-resistance)
Mechanical-risk gloves (AS/NZS 2161.3:2020) for handling cut hedge clippings and abrasive material. For chemical handling (herbicide/fertiliser mixing) switch to AS/NZS 2161.10.1:2024-rated nitrile/rubber. Anti-vibration glove padding can reduce hand-arm fatigue but does not eliminate Hand-Arm Vibration Syndrome (HAVS) risk — primary HAVS control is reduced exposure time and tool maintenance per ISO 5349-1 / AS 2670.1. Remove gloves when using secateurs/loppers if better dexterity is needed.
- Long trousers (heavy-duty, light-coloured)
Full-length trousers for protection against debris, scratches, and skin contact with fertilisers/herbicides. Light colours reflect heat (important for hot-weather outdoor work). Tuck into boots to prevent debris entry. (No specific AS/NZS standard for general work trousers.)
- Long sleeves and long-sleeved shirtAS/NZS 4399:2020 (UPF rating, optional)
Protection against UV exposure, flying debris, and chemical splash. Light-coloured, loose-fitting shirt allows air circulation for cooling. UPF-rated sun-protective long sleeves to AS/NZS 4399:2020 recommended for outdoor work. Long sleeves rolled down during spray operations.
- Sun protection (hat, SPF 50+ sunscreen)AS/NZS 4399:2020 (sun protective clothing UPF rating)
Wide-brim hat (minimum 7.5cm brim) or cap with neck flap. Australian outdoor workers carry substantially elevated lifetime skin cancer risk per Cancer Council Australia. SPF 50+ broad-spectrum sunscreen applied every 2 hours and after sweating. Sunglasses with UV protection (Category 3 minimum) if not wearing face shield.

Emergency Procedures
FLYING DEBRIS EYE IMPACT - Corneal Abrasion or Foreign Body: Stop work immediately. Wash hands, do NOT rub eye. If foreign body visible in eye white: use eye wash bottle to flush eye gently with water (do NOT attempt manual removal). If object on iris/pupil or if embedded: do NOT flush - cover eye with sterile dressing and seek urgent hospital eye care. Call 000 for serious eye injuries.
HEAT STROKE - LIFE-THREATENING EMERGENCY: Call 000 immediately. This is a medical emergency with mortality rate 10-50% if untreated. Move worker to shade immediately, remove all excess clothing including hat/helmet. Apply aggressive cooling using water spray/immersion and ice packs on neck, armpits, groin. Do NOT give fluids if worker is confused or semi-conscious (aspiration risk). Monitor continuously for recovery of consciousness. Continue cooling until paramedics arrive. Do NOT wait for cooling to improve symptoms - begin treatment immediately upon recognition.
HEDGE TRIMMER OR MOWER LACERATION WITH SEVERE BLEEDING: Apply direct continuous pressure with clean cloth/sterile gauze. If bleeding does not stop after 5-10 minutes: apply tourniquet above wound (for limb injuries) - tighten until bleeding stops completely. Call 000 immediately. Do not remove tourniquet. Mark time applied on tourniquet. For partial/complete amputation: place severed part in sealed bag with ice pack (not direct contact) and transport with worker.
LADDER FALL FROM HEIGHT: Assume spinal injury until proven otherwise. Do NOT move worker or attempt to sit them up. Immobilize spine: stabilize head and neck, support torso, do not roll or flex spine. Call 000 immediately for any height >2m, loss of consciousness, head impact, or neck/back pain. Do NOT allow worker to move until spinal injury ruled out by paramedics.
CHEMICAL INGESTION (accidental): Call 000 immediately. Call Poison Control (13 11 26) if available in your state. Do NOT induce vomiting. Have SDS available for paramedics. Monitor airways - worker may need CPR if breathing stops.

Frequently Asked Questions
What is the most common injury in garden maintenance work?
Eye injuries from flying debris (stones, grass pieces) are the most common serious injury in garden maintenance, representing 35-40% of serious injuries. Safety glasses or face shields are critical PPE for all line trimmer and hedge trimmer operation.
Why is hearing protection so important for garden maintenance?
Multiple pieces of equipment generate high noise levels: hedge trimmer 90-100 dB(A), line trimmer 95-105 dB(A), mower 85-100 dB(A). A full day using multiple tools typically exceeds the 85 dB(A) occupational exposure standard. Noise-induced hearing loss is permanent and cumulative - 10 years of unprotected exposure results in 20-30dB hearing loss.
Can I mow wet grass?
No - mowing should only be done on dry grass. Wet grass is slippery (50-60% reduced friction), increases slip/trip risk, clogs the mower, and reduces mowing quality. Wait for grass to dry after rain or morning dew.
What should I do if my eyes are exposed to line trimmer debris?
Stop work immediately. Do NOT rub eyes. If object visible: use eye wash bottle to gently flush eye continuously for 5-10 minutes. If object embedded or if symptoms persist after flushing (continued pain, blurred vision, light sensitivity), seek urgent eye care at hospital. Never assume minor discomfort will resolve without treatment.
How should I handle heat stress during hot-weather work?
Schedule work outside peak sun hours (before 10am or after 4pm) when possible. Drink 200-250ml water every 15-20 minutes (not just when thirsty). Take 10-15 minute breaks in shade every 1-2 hours. Monitor workers for heat exhaustion signs (excessive fatigue, headache, nausea). Heat stroke (confusion, loss of consciousness) is life-threatening - call 000 immediately and apply aggressive cooling.
What is the correct ladder safety technique for tall hedge work?
Position ladder on level ground only (use mat if uneven). Set at 1:4 angle (1m from tree for every 4m height). Maintain three-point contact (two hands + one foot, or two feet + one hand, always in contact). Never reach beyond arm's length from ladder - reposition instead. Use a spotter to monitor stability. Never use ladder in high wind or on slopes.
Can I apply herbicides safely?
Read the Safety Data Sheet (SDS) BEFORE opening any chemical product. Wear chemical-resistant gloves and P2 mask when handling dry powders. Spray only in calm wind conditions to avoid drift. Apply only recommended dilution rates. Never eat, drink, or smoke while handling chemicals. Wash hands thoroughly after application. Keep SDS accessible for worker reference.
What manual handling injuries are common in garden maintenance?
Back strain, shoulder strain, knee damage, and carpal tunnel syndrome are common from sustained overhead hedge trimming, carrying equipment, and repetitive gripping. Proper lifting technique (bend knees, keep back straight), team lifts for items >20kg, and task rotation every 30-45 minutes help prevent injury.
How often should powered equipment be inspected?
Powered equipment requires pre-start inspection EVERY time before use: check guards are present and intact, blade/cutting head condition, fuel/battery level, kill switch function, and leaks. Never operate equipment with damaged guards or missing safety features.
What should I do if a worker shows signs of heat stroke?
Heat stroke is a medical emergency. Call 000 immediately. Move worker to shade, remove excess clothing. Apply aggressive cooling: water spray/immersion and ice packs on neck, armpits, groin. Do NOT give fluids if confused or semi-conscious. Continue cooling until paramedics arrive. Heat stroke mortality is 10-50% if untreated.
