A friend of mine who works as an EMT and has also been a firefighter in the past asked me to bring up this topic. In the event you need to call 911, seconds count. Please make sure your house number is clearly marked in a location easy to see from the street. Time and again, these emergency crews expend crucial ticks of the clock trying to determine which house it is where they are needed.
If possible during an emergency, send someone outside to the end of the driveway to flag down the rescue squad, police, and/or fire crews.
With that said though, let’s say you’re home alone and suffer an injury. You are able to get to the phone and dial 911 but are unable to carry on a conversation with the dispatcher. Standard protocol is to send out a police officer to investigate 911 hang ups or 911 calls where the caller isn’t responding to the dispatcher. The 911 system is set up such that they can automatically trace the call to your address. But, don’t make them have to hunt for your house. Display your house number on your mailbox at the minimum, preferably also on or near your front door. Use reflective numbers and letters so it is easy to read at night.
