If you have to call 9-1-1 for an emergency do you know what to do? The first thing to do - STAY CALM! 

1. Try to remain calm. Take a deep breath when you're asked "What is your emergency?" This will help both you and the dispatcher to interact efficiently.
2. Cell phone or land line? Yes, we are in the age of the smartphone, but 911 calls from cell phones may not tell the 911 dispatcher where you are. With land lines, however, the address associated with that number will show up on a dispatcher's screen.
3. Know your location. If you do call 911 from a cell phone, this is crucial and important. The more accurate and detailed your location report is, the quicker dispatchers can get emergency crews to answer your call. Describing major cross streets and landmarks can help.
4. Be aware of your surroundings. This is not only helpful in determining your location, but it's crucial in helping you to describe other victims, the suspects, or other details about the scene.
5. Don't hang up. You may hear clicking, static, or pauses as the call progresses, but this doesn't mean your call has been dropped.
6. Let the 911 dispatcher guide the conversation. They are trained in this process and know about pertinent details that are usually required in the given situation.
7. Be patient. The call may seem to take forever or seem like it's being dragged out, but the dispatcher is most likely typing information into the system while simultaneously alerting services to your whereabouts.
8. Follow all directions. Be sure to ask for clarification if you don't understand, especially if the 911 dispatcher directs you to provide emergency aid.
9. Don't cry wolf. While you should feel free to call 911 in an emergency remember this....  If the situation does not require an immediate response by police, firefighters, or paramedics, consider calling a non-emergency number instead. (ie: you shouldn't call 9-1-1 for a power outage unless it's an emergency....instead call the power company.)
