Unless staying on the line would put you in danger, never hang up before the Telecommunicator does. The information you provide about what is happening can be relayed to police and fire responders, allowing them to react to changing conditions and circumstances at the scene. These updates can mean the difference between solving or stopping a crime, and could even help save lives. If you are in a dangerous situation, and must leave the phone, do not hang up; simply set the phone down, and then walk away. Doing this allows the Telecommunicator to hear what happens in the room even if you are not in a position to speak or answer questions.
People often call 911 about very difficult or uncomfortable situations. Even if the answer is difficult or embarrassing, it is important never to lie to the Telecommunicator. It is a crime to knowingly and intentionally give false information to the police, and misrepresenting the facts about a situation might put those who are coming to help in danger.
