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
