• Requirements for protection from fire in industrial buildings

 10-1  Industrial buildings: industrial   Buildings or its parts that are specialized for the purposes of industry or for industrial occupations: include various facilities of companies such as factories of dairies and furniture, clothing Wash, laboratories of hazardous chemicals, printing and industrial and artificial buildings and crafts workshops in all kinds.

 10-1/2  Trades Industrial buildings: the buildings or parts where the reforming process takes place.
 10-2  Seriousness of fire: the danger of the fire is classified in the industrial buildings by the type of manufacturing processes that are carried within these buildings  and they are as follows:
 10-2/1  Medium danger: the factories that manufacture, stockpiling or production of non-combustible or burning materials, or that its content burn in relatively medium degree of spread, or that releases an obvious amount of smoke but doesn’t produce toxic gases, and doesn’t form any explosions when it is burned as it is shown in table 1-1 chapter ‘general safe requirements for the buildings’.
 10-2/2  High risk: the factories that manufacture or assembly or produce combustible materials, or that its contents burn at high speed, or produce toxic fumes or explosion, as indicated in Table 1-1 in the section "general preventive requirements of the buildings."
 10-3  Structural requirements:
 10-3/1  Conditions of the first section must be applied to provide the safety of the structure against fire.
 10-3/2  The validity of the buildings are specified from the structural side in order to be used in industrial uses according to the Table 1-2 "Classification of buildings in terms of resistance to fire" The following table 10-1 "validity of the buildings to be used for industrial purposes."

• Validity of the buildings from the structural phase

to be used in industrial subjects according to the  seriousness of its work

 Categories classification  Seriousness degree
 First and second type only  Buildings with high seriousness
 All types The fifth type in a temporary time and certain conditions  Buildings with medium seriousness

 Table 10-1

 10-4  Different usages
 10-4/1  In case that the buildings of the industrial facilities, or shops professions are part of the premises of another use, they should be separated in order for each one to be an independent fire sector that have free means of escape.
 10-4/2  The parts of the buildings specialized for purposes other than industrial, must be treated with depending on the type of use.
 10-4/3  Parts specialized for the building must be separated from other part of different usage.
 10-5  Control the spread of the fire must be applied in terms of section I in addition to these conditions.
 10-5/1  Horizontal proliferation: the area of fire should not exceed what is being set in the table 10-2, and if partition was impossible due to the nature of manufacturing processes, civil defense may decide alternative precautions as required by the situation.
 10-5/2  The basement must be protected by providing it with a network of the water fire sprinklers if its area increase more than (150 meter square).

• The fire sector area in the industrial buildings according to the seriousness of its work

   The type of dangerous in industrial buildings    The area of the fire sector in m2 according to the floor
 Ground Floor  Basements and higher floors
 Medium-risk buildings  5000 meter square  1500 meter square
 High-risk buildings  1000 meter square  500 meter square

Table 10-2

 10-5/2  Vertical proliferation: The terms of Part I must be applied in addition to these conditions.
 10-5/2/1  In case there were too many floors, each floor is considered an independent fire sector.
 10-5/3  Outer-proliferation: The terms of Part I must be applied in addition to these conditions.
 10-5/3/1  The outer walls that are found on the borders of the property, from the neighbor’s side it must be built of bricks.
 10-5/4  Fire access vehicles: the arrival of the cars and equipments of the civil defense must be accessible to the industrial buildings.
 10-6  Ways to escape (emergency exits):
 10-6/1  The terms of section three must be applied ‘ways of escape’ in addition to these conditions.
 10-6/2  Absorptive capacity (absorption): The absorption is appreciated according to the means of escape for (emergency exits) 3-4 agenda, and for the places of other usage, absorption is determined according to the nature of use.
 10-6/3  Capacity: the width of the escape passages is calculated according to the number of people who use them as stated in Part III "ways to escape (emergency exits).under a condition that the width of the general corridors in the industrial buildings must not be less than (2m), and those secondary not less than (1.5m).
 10-6/4  Distance of transition: the transition distance should not exceed from any point to reach the final exit or the protected stairs less than the numbers listed in Table 10-3.
 10-6/5  Direct distance: the transition distance should not exceed from any point to reach the final exit or the protected stairs less than the numbers listed in Table 10-3.

 10-6/6  Corridors: You must provide the general conditions of the corridors as it came in the section ways to escape (emergency exits). Under a condition that the width of the corridors must not be less than (2m) and the secondary not less than (1.5).
 10-6/6/1  If industry place were not fixed or permanent, and the corridors are unclear, the corridors must be planned with a reflector paint, to clarify the corridors and work spaces or storage.
 10-6/7  Exits: conditions of section III "for ways to escape (emergency exits) must be provided in addition to these conditions.
 10-6/7/1  The number of exits must be in accordance with the general conditions of not less than two abroad directors to the parties of the building and on the outer wall, each leading to the outside.
 10-6/7/2  all exits must lead to the outside directly, or to the stairs or safe corridor against fire which is separated from the building with an isolating space.
 10-6/7/3  only one way out in the industrial buildings might be accepted if it has a medium degree of danger, with the approval of civil defense, if the following conditions:
 10-6/7/3/1  The depth or direct distance inside the section must not exceed 15m.
