Abstract
The most important factor in fire fighting at the scene of fire is a good combination of water, pumps and hose. Recently fire pumps have been much improved and many new fire trucks equipped with excellent pumps are distributed at fire stations, but unlined linen fire hose, that is the standard equipment of Japanese Fire Departments, seems to be behind in progress when compared with fire pumps.
The improvement of the present hose will mean indirect reinforcement of the existing fire fighting strength.
As the first approach towards the above improvement, we have made a series of tests on unlined linen hose of our Fire Department and found that each piece of hose tested showed some deterioration, while considerable number of pieces found unfitted for normal use. From these results we felt keenly that the improvement of hose quality along with the development of better maintenance and handling procedure is a key to our present problem of hose.
