Sanitary Engineering Solutions

Buildings of (КРУЭ перевод?) 330 kV and (КРУЭ перевод?) 110 kV on SS projected for the I degrees of fire-resistance. In building of (КРУЭ перевод?) -330 kV and (КРУЭ перевод?) -110 kV concordantly NAPB 06.015-2006, category on explosive and fire hazard of apartments - "D". For every building there must be no less than two outputs. Width of passage-ways for the ways of evacuation is accepted no less than a 1,0 m, width of doors - no less than 0,8 m.

In the apartment of storage batteries of building of (ОПУ перевод?), the pressurized accumulators, selecting the very negligible quantity of hydrogen in the mode of subcharge and boosting battery, are set. Taking into account permanent operating system of natural reveal-drawing ventilation and dissolution of concentration of hydrogen, this concentration can not attain explosive indexes. The apartment of storage batteries is subsumed «D».

External fire-fighting system is provided from existing on SS of the circular plumbing with fire-cocks.

Internal fire-fighting system from fire faucets is not used. For apartments foreseen only primary facilities of fire-fighting.

The gasket of cable is executed taking into account the requirements of gl.2.3 PUE. Concordantly NAPB 05.031-2010 in cable trays through 50 m, and also in the places of branches fire-prevention belts are foreseen from sand.

Fireproof cable passage-ways are foreseen through build constructions with the limit of fire-resistance no less EI60, compression of openings round pipes, cables - with the limit of fire-resistance no less EI60 concordantly p.3.16 SNiP 3.05.06.-85, p.10.5 NAPB V.01.056-2005/iii.
