“Should there not be more than two rows of storage tanks within a tank farm?
Thread Content
According to the provisions in the Code for Fire Protection Design of Petrochemical Enterprises, there should not be more than two rows of storage tanks within a tank farm. How should this sentence be understood? Can a maximum of 2 rows of tanks be placed within one fire dike? If there are a dozen or so tanks of the same type and they need to be arranged in 4 rows, is it then necessary to use a fire dike (a barrier)? ) Enclose them? __________ | | | O O | | | | O O | | | |__________|_______________________ | | | O O O O O O O | | | | O O O O O O O | | | |_________________________________| Ugh, it took a long time to draw this; does it look correct, everyone? Does it have to be this way? The tank area has this shape, but it’s not separated in the middle yet. Is it necessary to separate it? This post was last edited by chinazwr on 2009-4-2 19:37.]
“The storage tanks within the tank farm should not exceed two rows. ”It should be easy to understand: 8 tanks in a row, with 4 in each group ； 10 tanks in a row, 5 per row; there are two rows, and it’s not specified that the number of rows cannot exceed two.
This is not correct; it’s as if there are two tank areas, and they must be separated by a barrier, with fire barriers in place. This helps to enable simultaneous firefighting in case a fire breaks out in the storage tanks.
Article 5.2.8 The storage tanks within a tank farm shall not exceed two rows； However, for Class B storage tanks with a single-tank volume of 1000 m3 or less, there should not be more than 4 rows; there are no restrictions on the single-tank volume or the number of rows for lubricating oil tanks. If it’s for Category C B, I’m not sure if that should work. However, for Category A and B tanks, there should not be more than two rows. Pay attention to the red-colored tanks below; when fighting a fire, it is necessary to jump over one of these tanks in order to proceed. Therefore, it is not suitable. Other storage tanks should meet more requirements if they are surrounded by fire roads. Personal opinion, for reference only. __________ | | | O O | | | | O O | | | |__________|_______________________ | | | O O O O O O O | | | | O O O O O O O | | | |_________________________________|
It is related to the volume of the container and the properties of the material.
In other words, up to two rows of tanks can be placed within each fire dike; of course, it is also possible to have 4 or 5 tanks in one row. Additionally, regulations specify the maximum storage capacity allowed within a fire dike – the total volume of tanks in a single fire dike should not exceed this specified limit
The \"Code for Fire Protection Design of Petrochemical Enterprises\" provides very detailed explanations; asking this question indicates that it has not been read in its entirety. For Class A tanks with a volume of more than 1000 M3, the requirements specified for the 2nd and 4th floors must be met. The explanations for the 5th floor are quite detailed, along with relevant guidelines; there are also provisions regarding a fire safety distance of 120 meters and safety passages. If the area occupied by the tank cluster is small, it may not be necessary to provide safety passages between the tanks.
Thanks, Ha – I now understand a lot better: lol A Class tank area refers to one where the capacity of each tank is less than 1000 M3. According to what was said on floor 5, shouldn’t there be any storage tanks in the location of that red tank?
Agree with what was said on the eighth floor; the design standards should be studied carefully
It is mainly to consider rescue operations in case of a fire.
It should be determined based on the actual situation; it is recommended to read the standards first!
I think the owner’s setup does not comply with the regulations. Regarding what was mentioned by others above about clause 5.2.8 and the 1,000 cubic meter limit, this applies to Class C-B storage tanks; for Class A and B storage tanks, even if their volume is less than 1,000 cubic meters, the number of rows cannot exceed two. If fire dikes are used to separate them into two tank groups, then according to clause 5.2.13, a fire access road with a width of at least 7 meters must be provided.
Putting aside the convenience of firefighting, the poster’s diagram should meet the standards, right? Should we use a dike to separate it as soon as the volume approaches 1,000 cubic meters?
