What must a sign at a fire department connection indicate?

A sign at a fire department connection must indicate the type of fire system connection intended because it is crucial for firefighters responding to an emergency to quickly understand what kind of connection they are dealing with. This information allows them to determine the appropriate equipment and procedures needed to effectively use the connection, ensuring a rapid and efficient response.

For instance, knowing whether the connection is for a standpipe system, sprinkler system, or another type of fire protection system allows the fire department to deploy the right tactics and apparatus. This facilitates the swift and safe management of fire emergencies, reducing potential damages and aiding in the preservation of life.

The other options provided—such as the location of the nearest fire station, estimated response time, and the capacity of the water tank—do not directly assist firefighters in understanding how to utilize the fire department connection on-site, thereby making them less relevant for the purpose of the sign at the connection location.
