on the quantity of explosives,
class B explosives unable to mass explosion hazard, fire

class C explosives unable to mass explosion hazard, fire
raises the strong thermal effects and can quickly
expand. The surrounding area is mainly put at stake the flames, heat

"THE DETERMINATION OF SAFETY DISTANCES
(1) the safety distance shall be determined according to the basic formula
S = k. (M) n,
where S is the safety distance (m)
k is the coefficient of the elected according to the character and construction
implementation of the affected object, and the degree of damage
design and construction of an object affects the
M is the lining (kg)
n is the exponent whose value depends on a decking threatening
object.
(2) for the determination of safety distances from the object class and the danger,
In addition to the safety distance for the affected warehouse and production
the class of danger, and, the coefficients referred to in table 1 of this
the annex, while the values corresponding to an exponent n = 1/2 are used for
covering less than 2000 kg, corresponding to the value of the exponent n = 1/3
used for lining of 2000 kg and more. The value of the coefficient k of the
the range of the building affected by the implementation of the chosen object, its
meaning, nature, terrain, etc.
(3) for the determination of safety distances the affected manufacturing objects
classes and groups the risk of AI to AIV from warehouses and production buildings of class
danger and shall apply the coefficients listed in table 2 of this
Annex.
(4) in the case of explosives, which with its energy content significantly deviate
from trinitrotoluene, etc. some of the high explosives, pyrotechnical compositions,
explosives of the type DBT, vysokobrizantních explosives, M is:
and can be multiply by kekv), if its value is less than 1,
(b)) to be multiply by kekv, if its value is greater than 1.
The value of the coefficient of kekv are listed in table 3 of this annex.
(5) the safety distance from the object class and the danger in which they are
objects around in the explosion-threatening rozletem of heavy debris, is for
roads and railways at least 180 m and for residential buildings outside the territory
the establishment of at least 275 m.
(6) the safety distance from the object of class danger (B), which is
around threatened only rozletem light debris, shall be as follows:
and for any class) risk and production výbušinářského
operation in potentially explosive atmospheres is a safety distance of 15 to 90 m,
(b)) for the production without the risk of explosion is the safety distance
25 to 90 m,
(c)) for the administrative, social, energy or other objects not related to
manufacture of explosives is a safety distance of 40 to 90 m,
(d)) for roads and railways the safety distance is determined according to the
the basic formula, which uses the values of k = 39, n = 1/6; the smallest
However, the safety distance is 60 m,
(e)) for a residential building outside the facility security clearance
determined in accordance with the basic formula, which uses the values of k = 58, n =

(7) the safety distance from the object of class B in which the hazards are
objects around in the explosion-threatening rozletem of heavy debris and ammunition
caliber above 60 mm, shall be as follows:
and for any class) risk and production výbušinářského
operation in potentially explosive atmospheres the safety distance is 15 to 135 m,
(b)) for the production without the risk of explosion is the safety distance
25 to 135 m,
(c)) for the administrative, social, energy or other objects not related to
manufacture of explosives is a safety distance of 40 to 135 m,
(d)) for roads and railways the safety distance is determined according to the
the basic formula, which uses the values of k = 51, n = 1/6; the smallest
However, the safety distance is 90 m,
(e)) for a residential building outside the facility security clearance
determined in accordance with the basic formula, which uses the values of k = 76, n =
1/6; the minimum safety distance is 135 m.
(8) If it is possible to choose a safety distance referred to in paragraphs 6 and 7 of the
a certain range, according to building design-threatening and
the affected object.
(9) for the determination of safety distance from the object of class danger (C)
apply the exponent n = 1/3, and the coefficients listed in table 4 of this
Annex.
(10) if the lining of the object class of danger (C) less than 100 kg,
safety distance does not provide.
(11) the safety distance from the object of class danger (D) Assembly
100 kg and above is for all the buildings inside the establishment of at least 10 m,
for a residential building outside the establishment, roads and railways, at least 25

the distance reduced, or does not provide.
(12) if the lining of the object class of danger (D) less than 100 kg,
safety distance does not provide.
(13) in the different building design and the placement of hazardous objects
the explosion will determine the safety distance according to the following principles:
and if the object) is partially ovalován, then in the direction of the open sides
the safety distance is calculated as for object neovalovaný,
(b)) are two adjacent objects to each other through the open sides,
determine the distance between them as objects without barriers,
