If you are going to use a chainsaw to cut the branches off then the answer is no. Beyond this you will need to asses the risks to determine whether it is safe to do so. Please consider the following when determining what course of action to take.
- Do I need to climb the tree to cut the branch? If yes, do not cut the branch off.
- Could I get hurt if this branch fell on me or anyone I am with? If yes, do not cut the branch off
What are the risks associated with the branch’s removal? What tools am I going to use (not a chainsaw) and do I have appropriate Personal Protective Equipment (PPE)? If all of this is documented in a risk assessment and the outcome is that the branch can be removed safely, it is OK to remove it.
