Innovations in fire safety and examination of forces and means for extinguishing a fire in the ice palace “Baikal” in Irkutsk

Abstract

The aim of the work is to generalize innovative solutions in the field of construction of sports facilities and to examine the forces and means necessary to extinguish a fire in the Baikal Ice Palace in Irkutsk. To achieve this goal, the authors analyze the innovations proposed by Russian and foreign experts in the field of fire safety in the construction and operation of sports facilities. The effectiveness of modern innovative protection systems is discussed, such as fire extinguishing with remote control, fire alarms, robotic extinguishing systems, smoke protection in automatic and remote modes, control panels for evacuation control, etc. An analysis of the level of fire protection of an object was carried out using the example of an ice palace “Baikal”, for which possible scenarios of emergency situations related to fire were considered. It was possible to determine the forces and means necessary to extinguish a possible fire and conduct ASR (emergency rescue operations) using calculations of the fire area, the amount of the required fire extinguishing agent, the intensity of its supply, the number of involved units and units of the GDZS, the number of tankers. A method for calculating the stress state of a structure under the influence of a temperature load is proposed, possible schemes for the development of a fire are developed, and the necessary data for calculating the area and the number of mobile devices for extinguishing are obtained. During the inspection of the ice palace, it was found that the building provides for the protection of premises of any area with automatic fire extinguishing installations and fire alarms, robotic fire complexes (RPK) have been introduced. The success of firefighting depends on the correct placement and provision of sufficient firefighting forces and equipment, as well as on the careful choice of a decisive course of action. The objectivity of the assessment of the fire situation and the accuracy of decision-making are due to the highly professional training of the Cancellation Service Manager (RCD) and the ability to predict the development of fire fighting.
