ANALYSIS OF THE TECHNICAL REQUIREMENTS FOR THE FIRE-FIGHTING DELIVERY HOSES USED TOGETHER WITH THE FIRE-RESCUE EQUIPMENT
The urgency of the issue of substantiation of technical requirements to fire-fighting layflat delivery hoses for fire-rescue equipment is given.
Fire hoses are a significant component of fire fighting equipment. According to DSTU 2273, a fire hose is a flexible conduit fitted at the ends with connecting heads intended for the transport of extinguishing agents.
Among the technical means intended for the transportation of extinguishing agents to the fire cell, the main role is certainly played by delivery fire hoses. According to DSTU 2273 delivery fire hoses (in EU countries they are classified as "layflat") are intended for transportation of extinguishing agents under excess pressure.
At present, there are a number of standards in Ukraine and in the leading countries of the world that set the technical requirements for delivery fire hoses, in particular those used in conjunction with fire rescue equipment, namely DSTU 3810-98, DIN 14811, EN 14540: 2004 + A1: 2007, etc. In addition, a draft state standard is being developed in the Republic of Belarus.
Considering the process of gradual integration of Ukraine into the European Union and the fact that the requirements of the current national standard DSTU 3810-98 do not meet the modern European requirements for layflat delivery hoses for fire-fighting equipment, a pressing issue is the justification such types of hoses.
In order to assist in solving this problem, the Ukrainian Research Institute of Civil Protection is currently conducting a research work "Justification of fire hose test methods", within which a national standard will be developed, which regulates general technical requirements and test methods for the fire-fighting layflat hoses for fire – rescue vehicles.
The basic technical requirements for the specified hoses, which meet the modern requirements of the EU and which, after appropriate experimental justification, can be considered in the draft national standard, which regulates the general technical requirements and test methods for the fire-fighting layflat hoses for fire – rescue vehicles to be developed. This publication lists six tables that provide basic specifications for delivery fire hoses.
