Tree work is among the most dangerous jobs on any property, and the accidents are rarely freak events. They follow predictable failures: a cut made in the wrong order, a limb nobody noticed was under tension, a saw run from the top of a ladder. Tree felling safety comes down to planning, the right kit and the discipline to stop when conditions turn.
If you are hiring, this shows what a competent crew should be doing on your property. If you were thinking of doing it yourself, it shows how much sits behind a safe cut.
What makes felling a tree dangerous
The saw gets the attention, but the falling wood does most of the harm. Green timber weighs close to a tonne per cubic metre, so a branch as thick as your leg can outweigh you. These are the hazards our crews plan around:
- Kickback. When the tip of the bar catches wood, the saw is thrown up and back towards the operator in a fraction of a second.
- Barber chair. A leaning trunk cut in the wrong sequence can split vertically up from the back cut and kick off the stump with enormous force.
- Hung-up trees and hangers. A stem that lodges in a neighbouring crown, or a cracked limb caught in the canopy after a storm, can drop at any moment.
- Wood under tension. A bent branch or a pinned trunk stores energy like a loaded spring. Cut it in the wrong place and it whips sideways hard enough to break bones.
- Power lines. Contact with a live line, through a branch or a wet rope, is frequently fatal. If a tree is touching or close to a line, keep everyone away and report it to the electricity supplier before any cutting.
Cape Town adds its own twist. The summer south-easter can gust hard enough to push a falling stem metres off its line, and winter fronts leave trees waterlogged and rooted in soft soil. The tall gums and pines in many older Southern Suburbs gardens are brittle, often partly rotten inside and prone to dropping limbs without warning, which is why our tree felling in Constantia is almost always done in sections.
The kit and rigging a professional crew uses
Proper tree felling safety gear is built for chainsaw work, not general DIY. Anyone running a saw on a professional crew should be wearing:
- A chainsaw helmet with a mesh visor and ear defenders in one unit.
- Chainsaw-protective trousers, lined with long fibres that clog the chain before it reaches the leg.
- Cut-resistant boots with steel toes and grip soles, plus gloves.
Gear keeps a small mistake from becoming a hospital visit, but it does not replace method. Off the ground, our climbers work in a harness on ropes, and nobody runs a saw aloft without being tied in.
Near buildings we take trees down in sections: each limb is rigged on lowering lines, slings and pulleys and let down through a friction device rather than dropped. It is slower, and far safer.
Our guide to the methods of felling trees explains when a straight fell works and when it does not.
How a safe crew runs the site
No cut happens before the tree is read. We check species, lean, dead wood in the crown, cavities and fungal brackets at the base, and everything within falling distance: roofs, pools, walls, cables, cars and the neighbour’s side of the boundary.
Then the work area is run like a small construction site:
- An exclusion zone. Nobody but the crew comes within about twice the tree’s height during a fell, and a ground person controls access the whole time.
- Signals and escape routes. Saws make voices useless, so the crew agrees hand signals. Two escape routes are cleared at roughly 45 degrees behind the felling direction.
- A set cutting sequence. A directional notch faces the line of fall, then a back cut leaves a hinge of uncut wood that steers the stem down like a closing door. Wedges and pull ropes stop a back-leaning trunk from sitting down on the saw.
- Weather calls. If the south-easter or a winter front is moving the crown unpredictably, we reschedule.
The hazards do not end at ground level. Trunks under tension snap when cut, logs roll on slopes and a springy limb can throw a saw. The site is only safe once the wood and brush are processed and gone, which is why our quotes include clearing and taking the waste away. A stump left behind is a trip hazard, and our stump grinding service closes the job properly.
What you should do on the day
Near misses on felling jobs usually involve something nobody thought to move. Before the crew arrives:
- Move cars, trailers and bins well clear of the work area and the access route.
- Keep children and pets indoors until the crew tells you the cutting is finished.
- Clear pot plants, garden furniture, washing lines and ornaments from the area.
- Tell your neighbours, particularly if branches hang over the boundary or they park near the wall.
- Point out septic tanks, irrigation lines and buried cables so heavy timber and machinery stay off them.
Be there at the start to confirm the plan and at the end to walk the site with us, but stay outside the exclusion zone while cutting is under way.
Why DIY tree cutting goes wrong
We are not against homeowners doing their own garden work. But most serious DIY accidents follow the same pattern: a small job that grew. Someone means to trim one branch, ends up on a ladder holding a saw one-handed and cuts overhead. A ladder gives you no anchor, no escape route and a platform that moves the moment the limb drops. If a cut needs a ladder, it needs a climber instead.
Fatigue makes it worse: accidents cluster late in the day when arms are tired. A homeowner racing the sunset with a hire-shop saw usually has no chainsaw trousers, no helmet and nobody watching the crown. If you do not own the protective kit, treat that as the decision made.
Then there is liability. If your felling damages a neighbour’s wall or brings down a cable, you pay. Insured companies carry cover precisely because trees do not always behave, and our article on insured tree felling explains what to look for.
What is reasonable to do yourself
- Pruning shrubs and small branches you can reach from the ground with loppers or a pole pruner.
- Clearing twigs and light brush after a storm.
- Walking the garden each season and looking up for dead wood, cracks, fungus or a new lean.
Hand it over if the work needs a chainsaw above shoulder height, a ladder, or is within falling distance of a house, wall or line, or if the tree is leaning, dead or storm-damaged.
Check the legal side first
Before any cut, confirm the tree is legally yours to fell. A tree on the pavement belongs to the municipality, and a protected species such as a milkwood needs a national licence first.
Choosing a crew that takes tree felling safety seriously
Ask three questions before work starts. Is the company insured, with public liability cover for property damage and COIDA registration for its workers? Can they explain in plain language where each piece of the tree will go and how your structures will be protected? And will they put the scope in writing?
A reputable crew will happily walk you through the plan. If someone cannot tell you where the tree will land and why, do not let them cut it. If a quote for a large tree near your house says nothing about rigging or sectional work, keep looking.
