COLOR-CODED FIRE HYDRANTS


The National Fire Protection Association (NFPA) recommends fire hydrants be colored chrome yellow for rapid identification apart from the bonnet and nozzle caps which should be coded according to their available flow.

Color coding the hydrant tops and caps lets firefighters know how much water is available from the closest hydrant so that they can select the appropriate size hose lines for the size and complexity of the fire. This information is known as “available flow”.

The coding colors are as follows:


BLUE
1500 GPM or more
Very good flows
GREEN
1000-1499 GPM
Good for residential areas
ORANGE
500-999 GPM
Marginally adequate
RED
Below 500 GPM
Inadequate
