A damaged tree is dangerous because the wood is already loaded, and the cut that releases that load decides where the weight goes. A hung up limb is held by friction. A bent trunk is a spring. A limb resting on a fence is pushing on it. None of that behaves like a standing tree, and none of it gives warning before it moves. That is why storm damage hurts people who have cut plenty of firewood. The tool is not the problem. The load path is, and it is invisible until something lets go.
Stay out from under it and leave it alone. A broken limb caught up in the canopy, sometimes called a widow maker, is holding on by friction and a strip of bark, and both fail without a sound. Wind is not required, and a warm dry afternoon is enough. Do not hose it, poke it with a pole, or try to rope it from underneath, because every one of those puts a person in the drop zone. Rope off the ground under the whole canopy, move cars, and keep kids and dogs out of the area until a climber can get above it and lower it down.
Bent or pinned wood is under tension on one side and compression on the other, and cutting the tension side makes it snap and kick. Small saplings bent flat under a fallen tree are the classic trap, because they hold far more force than their size suggests and they come back up hard and fast. The same thing happens with a trunk that fell and is resting on a fence, a car or a roof, where part of the load runs through the structure and part runs through the wood. The fix is relieving weight in small pieces in the right order, not one confident cut.
No. A ladder gives you no way to move when the limb does, and a chainsaw needs two hands, which means nothing is holding you to the ladder. Cutting overhead puts the bar near your face and puts the falling piece on your same path. Add kickback, add a saw that pinches in a limb under tension, add a homeowner working alone with nobody watching, and the outcome is predictable. Climbers work off ropes and saddles for a reason, and lifts exist for a reason. If the cut is above your shoulders or off the ground, that is dangerous tree and branch removal, not yard work.
Treat every wire as live, including one lying on the ground, and treat the tree touching it as energized too. Do not move the branch, do not set a ladder, do not let anyone walk near the base, and keep vehicles away. Call the utility, and call 911 if a line is down. Only line clearance crews work near energized conductors, and no tree crew of any kind should start until the utility says the wire is handled. This comes up most after high wind, when a limb drops across the service drop running to the house.
Make the area safe and make it easy to work. Rope off or cone off the ground under the damage. Park cars away from the drop zone and out of the driveway, since a truck parked close cuts the debris walk in half. Unlock gates, and tell the crew where the sprinklers, septic lids and buried lines run. Take photos for your insurance before anything is cut. If something is leaning on the house, get people out of the rooms under it. Then wait. A hazard tree does not keep business hours, and JCC Tree Service is open 24 hours, every day of the week.
Emergency work stops the danger. It does not finish the tree. What comes next is usually a full removal or a set of cuts to balance what is left, plus a real cleanup, because storm debris piles up in volume fast. Look at the rest of your trees while you are at it, since the same wind that broke one often cracked another. Reading your trees before a storm is cheaper than calling after one.
