THE DANGER OF EXPLOSIVES CLASS
The explosives, according to the explosive conversion of behavior to be classified in
These classes of risk:
class A-explosive mass explosion, whereby
the surrounding area threatened by pressure effects and flying
the fragments. The severity of the injury and the extent of the damage are dependent
on the amount of explosives,
class B-explosives unable to mass explosion hazard, fire
explode individually. The pressure effect is limited to the
the immediate surroundings and on construction sites in the vicinity
arise only minor damage. Vymršťované items
explode and thus transfer the fire and explosion,
class C-explosives unable to mass explosion hazard, fire
raises the strong thermal effects and can quickly
expand. The surrounding area is mainly threatened by the flames, the heat
radiation and vyletujícími burning parts. Objects can
explode and be individually cast into the surrounding space.
Threat to structures in the immediate vicinity by the action of
Air shock waves is small,
class D-explosives present no significant hazard
for the surrounding area. The effects are limited to the individual packaging, when
fire isn't nearly the entire contents of a single package. Are
capable of burning, articles may individually
exploding. Eliminates dangerous fragments, size
range debris is small.

25 to 90 m,
(c)) for the administrative, social, energy, or other objects that are unrelated to
manufacture of explosives is a safety distance of 40 to 90 m,
(d)) for road and rail the safety distance is determined by 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 premises the safety distance
determined in accordance with the basic formula, which uses the values of k = 58 n =
1/6; minimum safety distance, however, is 90 m.
(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
over 60 mm, shall be as follows:
and for any class) risk and production výbušinářského
hazardous area operation the safety distance is 15 to 135 m,
(b)) for the production the object without risk of explosion is a safety distance
25 to 135 m,
(c)) for the administrative, social, energy, or other objects that are unrelated to
manufacture of explosives is a safety distance of 40 to 135 m,
(d)) for road and rail the safety distance is determined by the
the basic formula, which uses the values of k = 51, n = 1/6; the smallest
However, the safety distance is 90 m,
