• 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.
10-1/1	The premises of industrial occupation: the buildings or parts that are used for industry, in which the installation, mixing and packaging takes place.
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
The type of dangerous in industrial buildings	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.

•The expense of a transition and the direct distance of industrial buildings

location	Type of danger	floor
location	Type of danger	ground	basement
Direct distance inside the section	Middle	15	10
Direct distance inside the section	High	7.5	7.5
Transition distance to the exit or protected stairs	Middle	40	20
Transition distance to the exit or protected stairs	High	20	10
Closed ending	Middle	7.5	7.5

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.
