  Before operating an aerial lift, I first ensure that all safety features are in proper working condition and have been inspected. I then inspect the work area and secure the lift to the ground. While operating, I maintain a safe distance from hazards and follow manufacturer instructions for boom angles, elevator capacity, and weight distribution.

Tree Health & Diagnosis

• 14. Can you explain some common pruning techniques for maintaining tree health?
  

  Some common pruning techniques include crown cleaning, crown reduction, and crown thinning. Crown cleaning involves removing dead or diseased branches, crown reduction reduces the overall height of the tree, and crown thinning removes select branches to improve air circulation and reduce the tree's weight and wind resistance.

Tree Removal & Safety

• 15. What safety measures do you take while removing a tree near buildings or power lines?
  

  Prior to removing the tree, I check for any potential hazards such as nearby electrical lines and secure the area to prevent accidents. I then determine the best approach for removal, which may involve using ropes or rigging techniques to carefully lower branches and safely guide the tree to the ground.

• 16. How do you handle a tree removal project that requires stump grinding?
  

  I use a stump grinder to carefully grind the stump down to below ground level and remove any excess debris and roots. I then backfill the area with topsoil and plant grass seed or cover with mulch.

Emergency Tree Care

  I have experience responding to emergency tree care situations, such as fallen trees during storms or hazardous branches endangering property. I prioritize safety, communicate with any necessary authorities or property owners, and work quickly and efficiently to resolve the issue.

• 18. Can you describe the process of removing a tree that has fallen onto a building?
  

  When removing a tree that has fallen onto a building, I first secure the area and assess the damage to the building and the tree. I then carefully remove the tree in sections, ensuring that it does not cause further damage to the building. Once the tree is removed, I clean up any debris and inspect the area for additional hazards.

Tree Pruning & Maintenance

• 19. What factors do you consider when determining the best time to prune a tree?
  

  I consider the type of tree, its growth patterns, and the purpose of pruning.

I also consider the weather and avoid pruning during extreme heat or cold.

• 20. How do you ensure that a tree will heal properly after pruning?
  

  I follow proper pruning techniques, such as making clean cuts at the right angle and avoiding cutting the branch collar. I also use pruning tools that have been properly sanitized to prevent the spread of disease.
