In comparing with internal fire pipeline (IFPL) used from the 19th century, only traditional hardware of IFPL was updated, but design regulations for traditional IFPL and technology of fire hydrant using were permanent. In current set of rules 10.13130.2009 are mainly traditional IFPL requirements given but class of structural fire danger of different building types and their function are not considered. In the project of the updated version there are considered main regulations of the new edition of set of rules 10.13130, fire hydrant parameters of a new generation (low-consumed fire hydrants, including of water mist), dry pipes, fixed monitors are described, the algorithm for calculating the distance between fire hydrants is recommended; nomenclature of obligatory operational documentation, developed by planning organization, is proposed; the main accepted criterion for the hydraulic regime of fire hydrant is not pressure at the stop valve, but the reactive force of the jet, dispersed from the hand-held branch. The new classification of IFPL is introduced according to structural features of its hardware, pipeline appliance etc. Some regulations are specified for application and extension of hardware nomenclature of IFPL (pump installations including submersible pumps, fire tanks, pressure and flow indicator, location indicator, nonmetallic pipes, fire detection- and automatic control system etc.).
