Dead Acacia tree. Could it still be used for climbing at a school?

[RayZor Saw MT480]

Hello, I am new to this forum. I have recently become an international P.E. teacher and am working in Ethiopia. Acacia trees are abundant. There is one in our school playground, and because they are so fun to play on it has pushed out too much sap and died. It has a lot of little twigs on top that keep falling, so the higher-ups have sectioned it off from being played on. My hypothesis is to cut the top small branches, tie some ropes in it and from it, and use it as another piece of playground equipment. I need to come to the administration with some evidence, anecdotal or factual, and expert opinion. That is where you people from this forum come in.

1. Are Acacia trees still strong after they die?
   1. If yes, for how long?
   2. What is the diameter of a branch that should be considered climbable?
2. Have you tried out tree nets for kids?
   1. What about a lot of kids?
3. Would tying together green shade tops at the top after cutting away the branches help add strength to the tree, or would it create unnatural tension?
4. What other questions should I ask to get them answered to bring to the administrators?

Thank you for considering. Here is a picture of the tree. It is a beautiful tree but, in my opinion, very solid. According to some of the gardeners I spoke with, the root system is supposedly deep.

If it’s actively rotting, it’s just going to get weaker and weaker. Definitely do not invest in making it a play area. It’s better to hire someone to remove it safely, then you can continue planning for the playground. It’s nice of you to consider entertaining them, though!
