GLASS
Safety distance
The project documentation shall include the determination of the safety distance. This distance shall be calculated in accordance with Annex 2 to this Decree. The classification of explosives for the purpose of determining safety distances shall be carried out in accordance with Annex 1 to this Regulation. Where explosives of different hazard classes are stored in the warehouse as referred to in Annex 1 to this Regulation, the safety distance shall be determined according to the explosive of the highest class and group of hazards, taking into account the overall lining of the store.
Principles for the construction of a warehouse
(1) The warehouse is built as a single floor.
(2) The construction work of the warehouse is based on the type of material stored, storage techniques, handling and technology.
(3) At least one wall or roof of the warehouse must be in the exhaust.
(4) There shall be another exit at the warehouse in addition to the main exit if the length of the escape route from any point of the warehouse to the nearest exit is greater than 20 m.
(5) The main exit (entrance) of a warehouse surrounded by a rolling stock shall be placed closest to the passage of the rolling stock.
(6) A belt of non-flammable materials, such as concrete or tiles, shall be at least 1 m wide around the warehouse, which is drained and to which a fire strip of not less than 5 m is connected. The surface of the fire strip shall be covered with non-combustible material or, if necessary, shall be frozen. In the case of a flooded warehouse, the fire strip shall be built at least 3 m from the entrance to the warehouse and the result of ventilation shafts.
(7) The organisation shall ensure the warehouse or warehouse assembly by fencing at least 2,2 m high If the mesh is used, the mesh size may not exceed 0,05 m, with two rows of barbed wire superstructure. That provision shall not apply to the manufacturer to a warehouse or set of warehouses situated within the fenced area of the establishment.
(8) The fence distance from the warehouse shall not prevent the leakage of persons and shall be determined in the project documentation taking into account local conditions, linings, construction of the warehouse and protective measures.
Storage security
(1) The design documentation of the warehouse shall specify the method of securing the store against the theft or misuse of explosives, which shall be assessed by the expert or operator carrying out the security of the premises.
(2) The individual building parts of the warehouse (windows, walls, roof, etc.) must be sufficiently resistant to forced entry into the warehouse except for the elements in the exhaust. Entry into the warehouse shall be ensured by a mechanical defence system.
(3) The warehouse door is built as resistant to burglary. This requirement shall be deemed to be met if the requirements of the Czech technical standard, which lays down requirements for door resistance against burglary (3), are met, corresponding to at least safety class 4.
(4) The warehouse shall be equipped with an electronic signalling device to indicate a breach of the security of the warehouse (forced entry into the warehouse) in places with a permanent presence of persons. The place with permanent presence of persons is a continuously occupied workplace from which it is possible to report forced entry into the warehouse for 24 hours a day.
(5) Where a warehouse is permanently guarded in such a way as to prevent the theft or misuse of explosives, the provisions of paragraph 4 shall not apply to it, the intermediate warehouse and the carry-over warehouse shall also be subject to the provisions of paragraph 3.
Design requirements for individual warehouse parts
(1) The construction products of the reaction-to-fire class A1, A2 or B classified according to the legislation governing the technical conditions of construction fire protection 4 shall be used for the construction of walls, bulkheads, guarantees, doors, exhaust surfaces and roof structures. Construction products of wood can only be used with a treatment ensuring the reaction class to fire B classified under the legislation governing the technical conditions of fire protection building 4).
(2) Construction materials and coatings constituting explosive or incendiary mixtures and compounds with explosives must not be used.
(3) The surface treatment of the inner walls and ceiling of the warehouse shall be carried out in such a way as to allow effective cleaning.
(4) The roof of the warehouse may be made only
(a) as an exhaust, made of light, easy-to-break material, which does not endanger the environment in an explosion inside the building, or
(b) as resistant to the effects of explosion or reducing the effect of the pressure wave, firmly anchored in the surrounding walls and dimensioned to withstand or minimise the effects of the pressure wave and other effects of the explosion.
(5) The roof cover shall be made of such a mass that it cannot be spread through the cover in the event of a fire.
(6) The floor shall be flat and attached to the walls by curvature without clasps up to a height of at least 0,08 m above the floor. The surface of the floor is made of non-sparkling material and so as to be impermeable, with no cracks and easy to clean. The floor in the warehouse in which explosives with fire or explosion risk due to static electricity discharge are stored shall be carried out with protection against accumulation.
(7) Doors and frames can only be in design with opening out, without thresholds and tight throughout their perimeter. In the case of a black powder warehouse or explosives with a sensitivity similar to it, doors, frames, locks and fittings shall be carried out in such a way as to avoid sparks during friction or impact.
(8) When the doors are built as escape doors, they shall allow easy and fast passage. This provision shall not prevent the retreat of the evasive persons or the intervention of fire units.
(9) The windows shall be equipped with metal bars or nets at the window opening with a mesh size of not more than 0,02 m, painted in a light colour. The windows through which sunlight can pass shall be glazed with matte glass or glass without bubbles and spores or coated with white paint.
Protective bays
(1) Safeguards shall be established as closed, unilaterally open or unilaterally open with a separate bead.
(2) Only non-combustible and compacted materials may be used for the construction of the protective wall. If the protective wall is made of stoneware, a layer of sorted material with a thickness of at least 1 m with a grain diameter up to 0,016 m shall be used on its inside. The surface of the protective wall must be secured against erosion.
(3) The inner slope of the protective wall may have a slope of not more than 40 ° and a crown width of not less than 0,5 m. The profile of the protective wall shall be demonstrated in the project by calculation of stability including seating and pushing the wall body into the ground. The protective wall must not be planted with wood.
(4) The lower part of the inner slope of the protective wall may be replaced by a supporting wall which may not, however, exceed half the height of the protective wall.
(5) The crown of the protective wall must not be lower than the level of the roof ledge of the warehouse; for a warehouse with one-sided roof inclination, this applies to the roof ledge on the lower side of the roof. However, it is necessary that the crown of the protective wall exceeds by at least 0,5 m the upper level of the explosives stored.
(6) The side edge of the crown of an open or detached wall shall extend beyond the position of the warehouse by at least 0,5 m.
(7) The distance between the heel of the protective wall and the circumferential wall of the warehouse shall not exceed 2 m for a closed and unilaterally open protective wall and 5 m for a separate wall.
(8) The area between the heel of the protective wall and the warehouse is adjusted as a fire strip in accordance with § 6 (6) and must be drained.
(9) The passage in the protective wall shall be established as close as possible to the escape route from the warehouse by interrupting the protective wall or as a tunnel. The passage is at least 1,5 m wide, with a gradient of not more than 8 °.
(10) The passages are built arched or broken in such a way that any line through them intersects their wall protected by a protective bead. In the event of failure to comply with this condition, an additional protective wall or a protective wall shall be established at a distance of 1 to 4 m from the outer heel of the protective wall against the mouth of the passage of the additional protective wall or wall, overlapping by at least 1,5 m in all directions or at the same height as the cut-off wall and with a crown exceeding the edge of the cut-off wall by at least 0,5 m.
(11) The tunnel passage shall be at least 2,1 m high, illuminated, without any output. Its walls and ceiling are made of reinforced concrete or of equally durable material.
(12) A common wall between two warehouses must have no passage. The passage shall not be considered to be a transmittance for energy distribution provided that it is ensured against the transmission of detonation.
Protective wall
(1) A protective wall may be used instead of a protective wall.
(2) The protective wall must be securely anchored in the ground and its stability and resistance to explosion, supported by calculation in the project.
(3) The distance between the protective wall and the warehouse wall shall not be less than 2 m and more than 5 m.
(4) Paragraph 9 (5) and (6) shall apply to the determination of the height and length of the protective wall.
(5) The protective wall placed in front of the exhaust shall be so addressed that the explosion does not result in a dangerous control of the pressure wave, e.g. in the adjacent area.
Other equivalent protection
(1) The equivalent protection of the warehouse within the meaning of Sections 9 and 10 is made up of a grown forest or terrain inequality with parameters corresponding to the protective masses.
(2) The increased forest area referred to in paragraph 1 shall be wider than 15 m and its transparency shall not exceed 30% in the winter months. The evaluation of transparency shall be supported by calculations or photographs in the project.
Fire securing of the warehouse
(1) If no fire main is introduced into the warehouse, water supply or water supply must be provided in the water tower. The amount of fire water in the water tower, the diameter of the water supply pipe or the type and quantity of other fire extinguishers shall be determined in the warehouse project.
(2) Water distribution is conducted in a protective wall in a separate tunnel or passage. Hydrants shall not be placed against the free exhaust walls of the object.
Storage heating and ventilation
(1) The design of the storage unit, including ventilation and heating, must ensure compliance with the conditions for storage of explosives laid down by the manufacturer.
(2) Before work starts and during the work of persons in storage, effective ventilation must be ensured so that maximum permitted concentrations of pollutants in the air are not exceeded. 5)
(3) The ventilation equipment must be easy to clean and prevent the spread of fire.
(4) Temperature and humidity shall be checked in such a way as to comply with the conditions laid down for the storage of explosives.
Electrical equipment and protection against the effects of electricity
(1) Electrical equipment shall be set up in its design for potentially explosive atmospheres. This condition is met if the requirements of the relevant Czech Technical Standard (6) or equivalent technical standard of a Member State of the European Union, a State of the European Free Trade Association which is a Contracting Party to the Agreement on the European Economic Area, or Turkey, are met, provided that it guarantees at least an equivalent level of health and safety protection.
(2) The warehouse is protected from the effects of lightning.
Road transport
(1) Railway routes to warehouses cannot be used as transit routes for transporting other material.
(2) The sorting facilities for explosives are established at locations at least 300 m from the warehouses of all hazard classes.
