Today, it is known from the analysis of statistical
indicators around the world that 94% of the explosion
phenomena in industrial enterprises occur in
technological equipment, ventilation systems, filter
cameras and others. In 28% of cases, repeated
explosions occur in buildings, in the process of ignition
they participate in the form of waste products, as well
as dust, construction facilities and equipment, which
are released from technological equipment into the
room. Sediment dust is potentially dangerous, and
when assessing the risk of ignition in the room, it will
be necessary to take into account its quantity.
Therefore, since the amount of sediment dust causes
explosions in the ignition spark, the determination of
its amount in the air is one of the important issues and
necessitates the research work.

It is known that the dust in the production room
consists of two components, that is, dust in building
structures in the ground, in the air ducts, as well as dust
in the equipment. Ventilation and the total amount of
dust in the room indicate the stability of the production
room

in

the

stationary

technological

and

meteorological modes. The concentration of the raised
dust in the production premises of the inspected
enterprises, in rare cases, exceeds, this is less by 1%
than dust value of the lower limit concentration of the
flame. Therefore, when calculating the total amount of
dust placed in the room, it will also be possible to
ignore the amount of dust that has risen.

METHODS OF RESEARCH

This is evidenced by the fact that in the checked rooms
in a normal technological mode, as a rule, the
fulfillment

of

sanitary

requirements

is

ensured.Compliance with sanitary rules directly
ensures the safety of production explosions in cases
without accident. Therefore, from the point of view of
the explosion, the source of real danger is only

sediment dust, which, when switched to a suspended
state, can form explosive dust-air mixtures. The
separation and accumulation of flammable dust in
many manufacturing enterprises means that the
technological equipment works in the norm. The main
reasons for the accumulation of dust in the production
area have been studied as follows: absolute operation
of technological equipment, the inefficiency of the
systems of aspiration, the imperfection of the
equipment and the application of manual labor, which
make it difficult to aspirate. In many rooms under such
conditions, dust accumulates constantly. This process
was based on the model of the room dust regime. In
the development of the model, both current and
general cleaning work is carried out regularly in any
production associated with the release of flammable
dust into the room.

RESULTS

The percentage of dust that leads to the Upper Zone of
the room is due to the speed of the rising air flow and
the properties of the dispersed dust floor. Due to the
fact that theoretically it is not possible to determine
the speed of the air flow raised in production buildings.

CONCLUSION

Analysis of experiments on industrial enterprises
showed that natural concentration of dust in
production areas is occasionally. Therefore, from the
point of view of the risk of explosion, it is impossible to
ignore the amount of dust that has risen against the
sediments, and in addition, it is also necessary to pay
attention to the amount of dust that has settled on the
vertical surface and ceiling and to reduce the risk of its
explosion.
