A toolbox talk ready to deliver for foremen and supervisors. An 8 to 10 minute spoken script plus a briefing register for the team to sign.
A stump grinder looks like the easy end of the job, the bit you do once the tree is down and everyone has relaxed. That is exactly why it catches people out. The cutting wheel throws chips, grit and the odd hidden stone at real speed, and a lot of stumps sit right next to a path or a road with the public walking past. This talk is the script a supervisor delivers so the grinder is set up, guarded and fenced off before the wheel ever turns.
Stump grinding is covered by HSE guidance and current industry best practice, and the rules that apply to any powered machine apply here: trained operators, guards in place, and people kept out of the danger area. The wheel does not care what it hits. Buried metal, a flint, a chunk of old concrete, any of it can be fired out fast enough to badly hurt the operator or a passer by many metres away. Most of the harm from these machines comes from ejected material and from the public getting too close, and both of those are things we control before we start.
Spoken script for the supervisor. Read or paraphrase, in order.
Nobody runs the grinder unless they are trained and competent on that machine. It is not one you learn by having a go while the boss is on the phone. If you have not been shown this exact grinder and signed off on it, you do not start it, you find me.
Before the wheel goes anywhere near the ground, we check what is buried. Gas, electric, water, fibre and drains can all run right under a stump, especially near a house or a path. Use the plans and a cable locator, and if we are not sure, we do not grind. Hitting a live cable or a gas main with a spinning wheel is a very bad day.
The biggest danger is material being thrown out, so nobody stands in the firing line. Set out the guards, mats and screens the machine came with, and fence or tape a proper exclusion zone around the work. On a footpath or roadside that means barriers and a banksman keeping the public back. If someone walks into the zone, the wheel stops until they are gone.
The machine's own guards, deflectors and debris screens are there for a reason, and they stay in place and set correctly. Do not run it with a guard swung out of the way because it is quicker. If a guard is damaged or missing, the machine is off the job until it is sorted.
Before you grind, clear the loose stones, the bits of old fence wire and the rubbish sat around the stump, because that is exactly what gets thrown. Give the ground a look for anything metal or hard that the wheel will fire out. A minute clearing up front saves the stone that comes back at you.
Set the machine on stable, level ground and keep good footing yourself. Watch for slopes, soft ground and edges where the machine could slide or tip. Keep your feet and legs well away from the cutting wheel at all times. The wheel keeps turning after you take your hand off the control, so wait for it to stop before you go anywhere near it.
The only person by the machine while it is running is the operator. No one leans in to look, no one clears debris by the wheel, no one holds anything against it. When you need to move a guard, clear a jam or check the teeth, the engine is off and the wheel has stopped, every time.
Half these jobs are in front gardens, verges and pavements. People, kids and dogs will walk straight up if you let them, and they have no idea what a grinder throws. That is on us to manage: barriers, signage, a banksman, and stopping the moment anyone gets close. Assume they will not read the sign.
It is loud, it is dusty and it shakes, so ear defenders and eye and face protection go on and stay on, and mind your hand arm vibration across the day. Wear a dust mask where the grinding is throwing up a lot of fine stuff. Take the breaks, swap the operator round, and do not grind all day solid without a rest.
What the supervisor should be actively spotting on walk-arounds.
Ask one or two of these at the end. Confirms attention more than a silent nod.
