Advice 1: How to determine the class of the building

The class definition of the building shows its architectural value, significance, social and urban value, and the functional complexity of the building. In the design and construction can meet the most different types of buildings, therefore their klassificeret by a variety of symptoms.
How to determine the class of the building
Instruction
1
Define the class of buildings for the purpose. The building can be residential, designed for permanent or temporary residence; the public, intended for social service; industrial, designed to accommodate production; agricultural, suitable for agricultural production.
2
Define the class of buildings the number of storeys. For low-rise buildings include buildings from 1 to 5 floors. To include mid-rise buildings 5 to 12 storeys. To high-rise buildings are buildings with more than 12 floors.
3
Define the class of the building according to the design of the walls. In this case, the building klassificeret on makeelement and krupnoblochnye.
4
Define the class of the building according to the method of construction. To prefabricated buildings are the buildings constructed with panels or large blocks. To no industrial buildings include buildings constructed of brick.
5
Define the class of buildings for durability. It means determining the period during which the building will retain its performance properties. The I class of building is a public building in operation for over 100 years. To the second class belong building height of 9 floors with a lifespan of 50 to 100 years. To the third class shall include buildings with a maximum height of 5 floors with a lifespan of from 20 to 50 years. IV class are temporary constructions and buildings with a lifespan of not more than 20 years.
6
Define the class of buildings for fire resistance. Buildings with stone constructions belong to the class I and II. Buildings with wooden stucco walls belong to the class IV. Building with wood, not stucco walls belong to the class V.
7
Define the class of the building according to responsibility. The class responsibility is assigned to the project organization involved in the project. I define the class public and large industrial buildings as well as residential building with a minimum height of 9 floors. The second class includes small public and industrial buildings as well as residential building with a height of 9 floors. To the class III define a residential building with height up to 5 floors and buildings with average performance requirements. IV class are temporary buildings that have minimum requirements.

Advice 2: How to determine the class of fire hazard

The concept of "class of fire" is different from the categories of fire", which combines the features of production. The first concept complements the value of the latter, and therefore its classification is produced separately for each element of the production system for all its components, can cause and contribute to the course of fire.
How to determine the class of fire hazard
Instruction
1
Differentiate the classes of fire presented separately substances, materials, equipment, electrical wiring, structural elements of the building.
2
Remember that all substances are divided into 4 classes.
In the list of the fire elements of the 1st class take the explosive aerosols having lower concentration limit corresponding to the real threat of fire or explosion (below 15 g per cubic meter). Such substances are represented by sulphur, rosin, naphthalene, dust, peat, mill, ebony.
3
In the list of flammable substances of the 2nd class will include explosive aerosols having lower concentration limit corresponding to the real threat of fire or explosion, ranging from 15 to 65 g per cubic meter. Such substances are represented by lignin, aluminum powder, hay, flour and shale dust.
4
On the list of substances of the 3rd class of danger will get even more flammable substances. This aerogels having lower concentration limit corresponding to the real threat of fire or explosion, which is higher than 65 grams per cubic meter. The ignition temperature of aerogels — not more than 250° C. Such substances are, for example, silo, tobacco dust.
5
In the list of flammable substances of the 4th class to rank aerogels having lower concentration limit exceeding the value of 65 g per cubic meter, with the ignition temperature to 250° C. It is in particular zinc dust and sawdust.
6
Of particular importance in the concepts of "class of fire" give the classification of areas of the enterprise.
Determine the fire hazard zone as the space is outdoors, indoors, where there is constant or periodic flammable materials and substances.
