Standard Marking for Fire Hydrants

Standard Marking for Fire Hydrants

Some cities have adopted plans for marking fire hydrants so that it is possible to tell the character of fire stream that particular hydrant is capable of giving. On page 205 of this issue is presented a letter by J. W. Randlette, Water Works Superintendent, Richmond, Me., on the painting of fire hydrants.

At a meeting of the Maine Water Utilities Association held in Portland, Me., March 22, the following resolution was drawn up:

“Whereas, it has been established that sreat benefit accrues to both the Water Department and Fire Department to have the fire hydrants marked to indicate their capacity and,

“Whereas, we believe that the time has arrived when steps should be taken toward a national uniform marking of fire hvdrants and,

“Whereas, this association in 1929 adopted a system for marking hydrants in the State of Maine, therefore be it

“Resolved, that we urge the editorial staff of FIRE ENGINEERING to seek the cooperation of the various Fire Departments to the end that a national code of colors for marking fire hydrants be established”

This resolution was signed by J. W. Graham, General Manager, Portland Water District. A. W, Read. Superintendent, Bangor; Earle A. Tarr, Superintendent, Winthrop; Walter E. Abbott, Superintendent, Bath; S. S. Anthony, Superintendent, Augusta; S. D. Soule, Superintendent, Gardiner and J. W. Randlette, Superintendent, Richmond. These are the members of the association’s hydrant markings committee.

The standard adopted follows:

The barrels of the hydrants are painted a chrome yellow for visibility and distinct markings are used for the caps.

Class A. Hydrants which have sufficient supply for one or more pumpers or 1,000 gallons per minute. lops and nozzle caps green.

Class B. Hydrants which are capable of supplying pumpers with not less 500 gallons per minute. Tops and nozzle caps yellow.

Class C. Hydrants insufficient to supply pumpers of 500 g.p.m. Tops and nozzle caps painted red.

The suggested method of painting is to paint the entire hydrant first with a good metal aluminum paint and then to cover the first coat with the proper colors.
