Aside from shedding the tree, the most vital aspect that you have to consider during a tree removal is safety. With the dimensions of the tree that has to be taken down and the use of electric tools, tree removal is a threatening task. If you're doubtful of taking down a tree on your own, the task should be left in the hands of a pro.
Have the Tools and Protection
Such an undertaking requires you to dress appropriately to protect yourself. Your gear should ideally include a hard hat, eye and ear protection, guys, steel-toed boots, and leather work gloves. These things of clothing will not only shield you, but they can also allow you to work using the tools that you will need to take down the tree. The tools that you'll need for tree removal are a chainsaw, ladder, rope, and wedge. You may also wish to have someone else give you a hand through the entire process.
Evaluate the Tree and Its Surrounding Site
Ask a number of questions before you commence the tree removal project. In which direction does the tree lean? Is it free from people and other resources that might compromise a safe fall? Is the tree free from cracks and rotten sections that might permit it to fall at a unprecedented or unplanned time and direction? You might also need to consider the prevailing weather. In which direction is the wind blowing? Is it tough enough to change the direction of the tree as it falls?
Plan Your Escape Route
As soon as your tree starts falling, you will need a safe place where you can run to, so that you are guarded from the probable risks that a falling tree can possibly inflict on you. The trail should be 20 feet from the tree and may be at a 45-angle from the tree that you have selected for tree removal. You may even position yourself behind another tree for extra protection.
Once the tree starts falling, run through your escape route and never look back till you hear the thud. Only then should you look back, and go back to inspect how your tree removal job went.
