FOG FIRE EQUIPIiSNT 



A fruit grower exporting apples .aay sustain a heavy loss if the cargo i:? 

 lost at sea or his crop is damaged in transit. But his loss is much greater 

 If hiP apple storage burns davm before he can dispose of the stored apples. 



Realizing that the pressures developed by orchard sprayers produce a 

 superior fog type of spray, especially effective in fighting fires, state aiia 

 county officials in some states have adopted their use. In Kent County, 

 ■lichigan, two fog type spray outfits were obtained several years ago and 

 housed in the garages of the highway department in rural areas. Today that 

 county has seven outfits. All the firemen are volunteers. 



Some agricultural engineers believe that orchard sprayers represent one 

 of the most effective types of fire engines ever developed. The average spra;. 

 tank full of water applied in a fog may be fully as effective in fighting a 

 fire as two to three thousand gallons applied in a solid stream. 



The fog expelled from a gun at customary orchard pressures is so fine 

 that v;nen it contacts the fire it turns to steam. 'Vhile this happens it absorbs 

 heat and it helps to push the oxygen away from the fire. This accounts for the 

 amazing speed with which these fog guns subdue a fire, and with much less 

 water than a conventional fire engine uses, Water damage to property is reduced, 

 and the limited supply of water in most rural areas is utilized to the utmost. 

 In the February lOth issue of "Fruit Notes", ah article offered suggestions 

 on keeping a spray rig in readiness for fighting fires in v/inter. Not only 

 grov/ers, but rural communities, are adopting this safety measure in some 

 states, 



Pennsylvania State College has received most favorable reports from 

 thirty towns using fire trucks equipped for high pressure applications of water 

 with fog guns. Neighboring fire companies show a fine spirit of cooperation. 

 The many tliousands of spray rigs on U, S, farms could be of tremendous value 

 in reducing the 0100,000,000 annual loss from rural fires,
