Abstract

Buildings or properties seriously damaged due to detonation of explosives, gas explosions, technological accidents, and other emergency’s threaten their surroundings with their instability. Their damage is usually so significant that no repair or reconstruction is ever considered, demolition is inevitable. In such hazardous situations, use of special charges could be the possible solution for a safe disposal of damaged and statically unstable structures. Use of this emergency pyrotechnic instrument could eliminate or considerably reduce the possibility of health hazards of intervening people, rescue equipment and surrounding properties during the disposal process of extremely damaged buildings in a very short time, mainly in neighbourhoods. A System of special sequentially timed charges use the increase of efficiency of external charges and cover with water-bags together with the increase of efficiency of the whole system due to their timing. Developed charges increase the operability and safety of rescue units of IRS (Integrated Rescue System).
