FOG NOZZLES PROVE EFFECTIVE ON SMALL INTERIOR FIRES
Western Fire Chief Employs Device with Good Effects
FIRE Chief Henry Quane of Anaconda, Mont., has been experimenting with the fog nozzle for some five years and recommends its universal adoption. We have witnessed many of the experiments he has conducted. The type he uses comes in sizes adaptable to hose diameters from garden hose to 2 1/2 inches and is attached by removal of regular nozzle tips with which all Fire Departments are equipped. It operates at greatest efficiency as follows:
Garden hose size, 115 pounds pressure; three-quarter-inch size, at 130 pounds pressure: 1 1/2-inch size, at 150 pounds pressure; 2 1/2-inch size, at 175 pounds pressure.
In the use of the garden hose size, it is siamesed for fifty feet from a three-quarter-inch booster line two hundred feet long. It produces a fog or mist which when it comes in contact with fire instantly converts into steam and stops all blaze within a radius of seventy-five to one hundred feet or more.
Usefulness of fog nozzles is greatest when the Fire Department reaches the scene of the loss before openings are broken out or walls or roof burned through, and most fires are caught in this early stage. Furthermore the firemen can follow into the room without fear of too much heat.
Progress in solving the effective use of this modern invention is best expressed by comparison. Recently the writer had two losses, one in Anaconda, handled by Chief Quane, and one in a city not far away. Both fires originated in outside walls of frame residences caused by defective construction of fireplaces. The method used in the one location was to tear away plaster and lath in walls and partitions and part of fireplace, causing a repair bill of approximately $175 as a result of water and breakage, while Chief Quane, upon arriving at his loss, bored a two-inch hole in the outside wall and inserted the fog nozzle of the garden hose size, reduced the blaze without permitting moisture even to penetrate the plaster or destroy interior decoration. The result in his case was repairs costing $5.
The writer adjusted both claims and was so impressed with the results obtained where the causes of the fires were identical that we became interested and started our study of this attachment. We admit that some element of poor judgment was responsible for much of the damage in the first case cited; however, the outcome would still overwhelmingly justify the method used by Chief Quane.
We can recommend universal use of fog nozzles because their effect is instantaneous; moisture damage, minor; economy, advantageous, and their application simple. A fog nozzle was used at a fire in a hardware store, twenty-five by seventy-three feet, and stopped the blaze in this large building, where the fire was fed by a barrel of turpentine, a barrel of alcohol and 240 blazing automobile tires standing near the point of origin. Our investigation disclosed that the water damage in this store was comparatively small, considering the extent of the fire and the extreme heat which was sufficient to crack the plate glass front, protected by a partition back of the show window bulkhead.
We have seen so many fires during our years of adjusting experience where water was the cause of seventy-five or eighty percent of the damage done. Therefore, we desire to greatly emphasize the minimum of water damage when the spray or fog nozzle is utilized. There has been great effort expended in educational work toward Fire Prevention, which is most commendable in a country where the fire loss ratios are the highest in all the world. Our experience of the past few years would indicate that this program has been successful to some degree. Therefore, it might be reasoned that an effort be expended to create general adoption of this new method of fighting fires. I am firmly convinced that such action would consummate in a large percentage reduction in water damage.
We believe that Fire Chief Henry Quane of Anaconda deserves much credit for his valuable contribution in the adoption of this method of fire fighting. Others could profit by his experience.
