People, a building or utility equipment face immediate danger
A tree contacting electrical equipment, actively shedding large pieces or affecting an occupied structure is not simply a cleanup scheduling problem. Explain the immediate exposure when contacting emergency responders or the serving utility. An urgent response can secure a danger without deciding the eventual scope of removal, repair or insurance coverage. Those are separate decisions once access is controlled.
Notice next: Use a safe location to describe who or what is exposed. Do not send a family member into the area to photograph the damage.
