TECHNICAL MEANS FOR TIME REDUCTION OF DELIVERY HOSE ROLLING

Abstract

One of the ways to increase the efficiency of firefighters' actions is mechanization of their work. It includes the process of delivery hose rolling after fire that is a very intensive and time-consuming activity. To accelerate this process it is suggested to use hose line purging device and device for hose rolling. Purging with compressed air allows forcing out the residues of extinguishing agents from hose lines quicker, and mechanization of hose rolling process helps to reduce time of this activity. The test results analysis of these devices shows that hose line purging before its dismantling allows making a hose rolling process 3-31 seconds quicker. It depends on the quantity of hoses in the line: the more hoses, the more time saving. Mechanization of hose rolling process allows to reduce the time of their collecting more than for one minute for each hose. Thus the use of these devices increases the efficiency of firefighters' actions during fire danger period or in cold weather conditions.
