ABOUT IMPROVEMENT OF THE REGULATORY BASE FOR TECHNICAL REQUIREMENTS AND TEST METHODS FOR DELIVERY FIRE HOSES

Abstract

The urgency of the development of the corresponding national standard, which regulates the technical requirements and test methods for the layflat delivery fire hoses for fire vehicle. Currently, the Operative Rescue Service mainly uses pressure hoses of the “T” type (for fire vehicle ) with a diameter of 51 mm and 77 mm, the technical condition of which often does not meet the requirements, which may not withstand the pressure that pumps of even traditionally used fire vehicle develop when extinguishing fires. The use of such hoses in extinguishing real fires can limit the ability, reduce the effectiveness of operational and tactical operations of operational and rescue units, as well as put personnel at risk. Today, there are a number of complaints from Civil Protection Operations and Rescue units regarding substandard fire hoses being purchased and operated. Basically, the complaints concern the non-conformity of these products with respect to the pressure requirements and the wear resistance of the surface of the material from which it is made. Over the past three years, the State Emergency Service has purchased about 120 fire vehicle each year, which are completed with fire delivery hoses with diameters of 51 and 77 mm. The requirements of the current national standard DSTU 3810-98 in Ukraine are outdated and do not meet the practical needs of today. Taking into account that new types of fire hoses and technologies of their creation have appeared in the leading countries of the world, and considering that the standard in Ukraine DSTU EN 15889: 2017 does not apply to layflat delivery fire hoses for fire vehicles, the issue of developing a national standard for this type of fire hose is urgent. In addition, European regulatory document CEN / TR 16099 states that the EU does not have a single standard that sets the technical requirements for "flat-fire attack hoses", ie those used with fire-fighting pumps. In EU countries, this issue is likely to be governed by the individual national standards of the Member States. This is confirmed by the German national standard DIN 14811-2008 / A1-2012, A2-2014. The technical characteristics and test methods of fire hoses in accordance with current DSTU 3810-98 and German standard DIN 14811-2008 are given. On the basis of analytical research the methods of testing layflat delivery fire hoses are specified, which will be given in the draft national standard. Keywords: layflat delivery fire hoses, rescue vehicles, specifications, test methods.
