According to the above, technological failures in the steady process conditions have a
low degree of probability.
The projected production equipment complies with the rules of operation, so the
possibility of accidents associated with mechanical failure is almost completely excluded.
Organizational, technical failures, causing accidents, almost impossible, because the
reduction or excess volume of processed gas is in the range of installed capacity. Otherwise,
the emergency stop units occur automatically or manually triggered protection by pressing
the emergency stop.
With regard to emergencies caused by natural disasters, particularly earthquakes,
they are unlikely, because the structures are located in a zone of low seismicity, and the
buildings and equipment are calculated taking into account possible earthquakes.
are:
Quantitative characteristics of the harmful effects of a possible emergency process
- The value of the possible deadweight loss (ie the number of deaths due to
accidents);
- The value of the possible loss of human health (ie, the number of victims who
require hospitalization);
- Expected frequency of accidents.
The object in question is classified as potentially hazardous. The severity of fire
sources of substances determined by their volatility. In this case, gases are 4 class of danger
with a boiling point 253oK.
Cause ignition of an explosive mixture can be an open flame, a spark from hitting an
iron object, a spark of electrical devices (circuit breakers, furnaces), etc. When lighting
equipment is necessary to consider the possibility of gas accumulation, so all the wiring
must be explosion-proof lights, or reflectors must be installed in window openings, or
special. Fire safety and explosion-proof manufacturing processes ensure the development
and implementation of systems to prevent fires and explosion protection systems.
However, when the equipment is projected construction accidents can still occur due
to excess pressure in the pipelines due to the formation of gas-air mixture at concentrations
capable of provoking an explosion, followed by ignition of gas.
Emergency situations are impossible to predict either at their place of origin, nor in
time. Therefore, in evaluating the parameters of emergencies and their harmful effects on
health and safety of people allowed some assumptions.
Thus, under all operating rules and safety measures the likelihood of accidents is low
and, according to RD 118.0027714.24-93 priori frequency of accidents on pipelines is 10-5.
Reliable trouble-free operation facilities designed to ensure strict compliance of
technological regime, all job descriptions both production and safety, good technical
training staff.
The main binding conditions of safe processes are:
