Tree crew safety: the phrases nobody can afford to mishear
A tree job is the loudest place in landscaping. A chainsaw forty feet up, a chipper at the curb, a truck backing in — and the only thing holding it together is a handful of short calls between the climber and the ground. They have to land in a half second, over the noise, in whatever language the person hearing them thinks in.
If your groundman thinks in Spanish, the English call is a translation problem at the worst possible moment. Here are the ones that matter, with the Spanish the ChambaTalk glossary uses — free at https://app.chambatalk.com/glossary, every one marked safety-critical.
The drop zone
The drop zone is where the wood lands. Nobody works in it while there is a cut in progress, and everybody knows where its edge is. For felling, the rule of thumb is two tree lengths.
| English | Español |
|---|---|
| Clear the drop zone before he makes the next cut. | Despeja la zona de caída antes de que haga el siguiente corte. |
| Everyone outside two tree lengths before he starts the back cut. | Todos afuera de dos largos del árbol antes de que empiece el corte de atrás. |
| Nobody moves brush under the tree while the climber is cutting. | Nadie mueve ramas debajo del árbol mientras el trepador está cortando. |
| There’s a widow-maker in that oak — nobody works under it until it’s down. | Hay una rama colgada en ese encino — nadie trabaja abajo hasta que la bajemos. |
“Headache!”
On an English-speaking crew, “headache!” is the traditional call for something falling from above. It does not translate — a Spanish speaker new to US tree crews hears a complaint about a sore head. The Spanish call is ¡Aguas arriba! Mexican crews also shout ¡trucha!, and the all-purpose warning is ¡Aguas! Pick one per language and make it the crew’s word, so nobody decides which shout means what while a limb is already moving.
| English | Español |
|---|---|
| Heads up! Dropping a board. | ¡Aguas arriba! Va una tabla. |
| Watch out! The load is swinging your way. | ¡Aguas! La carga va hacia ti. |
| Load coming down — clear the drop zone. | Va bajando la carga — despejen la zona. |
The chainsaw
Kickback is contragolpe; workers from elsewhere may say rebote. Chaps are chaparreras. The felling cuts have names — muesca, corte de atrás, bisagra, cuña — and a crew that shares them can talk about a leaning trunk before it becomes a barber chair.
| English | Español |
|---|---|
| Never cut with the tip — that’s how you get kickback. | Nunca cortes con la punta — así es como te da el contragolpe. |
| No chaps, no chainsaw — put them on before you start it. | Sin chaparreras no hay motosierra — póntelas antes de arrancarla. |
| Face the notch at the open lawn, not the fence. | Apunta la muesca hacia el pasto abierto, no hacia la cerca. |
| It’s leaning back — set a wedge before you cut deeper. | Está recargado hacia atrás — mete una cuña antes de cortar más. |
The chipper
The chipper is chipeadora on most US crews; the glossary also lists astilladora and trituradora. Feed from the side, keep ropes away from the infeed, and the chip truck never backs up without a spotter — señalero.
| English | Español |
|---|---|
| Feed the chipper from the side and keep the ropes clear of it. | Alimenta la chipeadora desde el lado y mantén las cuerdas lejos de ella. |
| Nobody backs the chip truck without a spotter. | Nadie echa en reversa el camión de chips sin señalero. |
| Poison ivy — gloves and sleeves, and bag it, don’t chip it. | Hiedra venenosa — guantes y manga larga, y a la bolsa, no a la chipeadora. |
The bucket and the power lines
The aerial lift is canastilla. Outriggers go down and level before it goes up, and anything near power lines is a call to the utility, not a judgment call. OSHA sets minimum distances from energized lines that depend on the voltage and on whether the worker is qualified for line-clearance work; ten feet is the figure crews quote for anyone who is not. Follow your company’s number, and when in doubt, do not touch it.
| English | Español |
|---|---|
| Outriggers down and level before the aerial lift goes up. | Estabilizadores abajo y nivelados antes de subir la canastilla. |
| That limb is hanging over the power lines — we call the utility, we don’t touch it. | Esa rama está encima de los cables de luz — le hablamos a la compañía, no la tocamos. |
Climber and groundman: the script
The industry standard for tree work, ANSI Z133, expects a command-and-response system between climber and ground, with the ground crew acknowledging before a cut. The exact words are up to the crew. Here is a set built from glossary phrases; the point is that the groundman answers every call, and no cut starts until he does.
| English | Español |
|---|---|
| Climber: Rope that limb before I cut — it’s over the fence. | Trepador: Amarra esa rama con cuerda antes de que corte — está encima de la cerca. |
| Groundman: It’s ready. | Ayudante: Ya está listo. |
| Climber: Clear the area! | Trepador: ¡Despejen el área! |
| Groundman: Clear. | Ayudante: Despejado. |
| Climber: Heads up! | Trepador: ¡Aguas arriba! |
| Groundman: Lower it slowly, don’t drop it. | Ayudante: Bájale despacio, no lo sueltes. |
| Climber: Don’t let go until I say so. | Trepador: No lo sueltes hasta que yo te diga. |
| Groundman: That’s good right there. | Ayudante: Ahí está bien. |
| Groundman: Stop! The rigging is loose. | Ayudante: ¡Párale! El amarre está flojo. |
| Climber: Are you okay? | Trepador: ¿Estás bien? |
Run it once at the trailer with the saw off, in both languages, before the first cut of the day. Then run it for real. The crew that has said ¡Párale! in practice is the crew that says it in time.
The glossary has the rest of the tree vocabulary — desramar, trocear, el método de tres cortes, reducción de copa — with an example for each, and the app’s talk mode will say any of it out loud. More on the tree and lawn side at /landscaping.
