by explosive-fire-hazard. During design there have been taken into account requirements for
necessary quantity of evacuation exits, and have been avoided crossings cargo and people
streams. In case of explosion there are provided in explosive premises the easily dropped
constructions. It can be window apertures and coverings. There are provided spark-proof
floors in premises or constructions of categories: A, B, C.
For fast response during emergencies origin on the industrial areas there is a complex
of buildings and constructions of fire-prevention purpose:
- pump stations of household and fire-prevention purpose;
- fire-prevention water-supply tanks;
- automatic firefighting pump stations;
- automatic firefighting water tanks.
There are provided following action for the purpose of decrease of production fire
hazard:
- all stop and safety valves is accepted by 1 class of flap tightness;
- there are installed gassed condition signalling devices in explosive premises;
- electric equipment in fire-explosive premises and on external areas is
designed in explosion-proof version;
- technological pipelines are laid underground or on fireproof support;
- explosive- and fire-hazardous substances are removed from premise by
exhaust ventilation system;
- valves and pipeline are estimated on the pressure exceeding the maximum
possible working pressure for reduction of emergency;
- if the devices are stopped for repair the liquid rests are drained in the
drainage tank, and gases are freeing on a torch.
Antiseismic measures
All buildings and constructions were designed taking into account seismicity:
selection of all precast ferroconcrete and steel elements of the structures is executed by
typical materials developed taking into account seismicity, the buildings foundations were
are estimated on the special combination of loads, i.e. during action of seismic force.
Thus, the provided antiseismic measures are directed on maintenance of reliable and
safe use of buildings, constructions, and, accordingly process equipment operation.
Technological communication
The communication system is intended for operative and continuous control of
technological processes, maintenance of effective interaction of the factory divisions, and
also maintenance with communication of emergency, rescue and other services during
liquidation of consequences of failures, acts of nature and other emergency situations.
