Why Strimmer Safety Matters

A strimmer can:

• Throw stones and debris at high speed
• Cut skin instantly on contact
• Cause eye injuries in seconds
• Lead to slips and falls on uneven ground
• Create fatigue-related accidents during long use

Used correctly, a strimmer is safe. Used carelessly, it can be dangerous.

Always Wear Proper Safety Gear (PPE)

Before you start strimming, wear:

• Eye protection – flying debris is the biggest risk
• Sturdy footwear – steel toe or thick-soled boots preferred
• Long trousers – protects legs from debris and line contact
• Gloves – improves grip and reduces vibration
• Hearing protection – especially for petrol strimmers

Avoid loose clothing that could snag on the cutting head.

Check the Area Before You Start

Always inspect the area first:

✔ Remove stones, sticks, wire and toys
✔ Watch for hidden edging, roots or metal
✔ Check for uneven ground or slippery slopes
✔ Look out for pets, children and bystanders

Most debris injuries happen in the first few minutes.

Use the Right Strimmer for the Job

Not all strimmers are suitable for all tasks.

• Use line strimmers for grass and light weeds
• Use heavy-duty or blade-capable strimmers for nettles and thick growth
• Don’t force lightweight tools into heavy vegetation

Using the wrong tool increases kickback and loss of control.

Correct Starting & Handling Technique

• Start the strimmer on clear ground, not in grass
• Hold with two hands at all times
• Keep the head below waist height
• Maintain a stable stance with good footing
• Let the line reach full speed before cutting

Never raise the cutting head towards your body.

Safe Cutting Technique

• Trim in smooth arcs, not stabbing motions
• Work away from your body, not towards it
• Keep the guard fitted at all times
• Avoid hard edges like paving and fencing
• Reduce speed near obstacles

Let the tool do the work — forcing it increases risk.

Extra Safety for Wet or Sloping Ground

UK gardens are often damp or uneven.

✔ Wear footwear with good grip
✔ Take smaller passes in wet grass
✔ Avoid steep slopes when possible
✔ Be mindful of cable position on electric models

Slips while strimming are a common cause of injury.

Cordless, Electric & Petrol Safety Differences

Cordless Strimmers

• Remove battery before maintenance
• Keep battery dry and clean
• Avoid crushing or dropping batteries

Electric (Mains) Strimmers

• Keep cable behind you at all times
• Use an RCD-protected socket
• Never strim in heavy rain

Petrol Strimmers

• Refuel only when cool
• Never refuel near ignition sources
• Use hearing protection
• Store fuel safely away from heat

Never Do These Things

❌ Remove safety guards
❌ Strim in sandals or barefoot
❌ Operate above shoulder height
❌ Use damaged line or blades
❌ Allow children near operating strimmers
❌ Work while tired or distracted

Most serious accidents happen when shortcuts are taken.

Take Breaks and Avoid Fatigue

Fatigue reduces control and reaction time.

• Take regular breaks
• Stretch hands and shoulders
• Stop if vibration or numbness starts
• Use harnesses for heavier strimmers

Tired gardeners make mistakes.

After Use Safety

✔ Switch off and unplug/remove battery
✔ Let petrol engines cool before storage
✔ Clean debris from the head
✔ Store out of reach of children

Safe use doesn’t stop when the cutting does.
