Can bridges be installed on the fire embankment wall?

The fire embankment cannot be installed with bridges, and irrelevant process facilities cannot cross the storage area.

I've seen it in many oil depots, but I haven't seen any clear regulations prohibiting it. Generally speaking, the cable bridges in the fire embankment are laid on pipe piers, and there is no essential difference from those installed on the fire embankment.

There should be no problem with temporary things during construction.

Generally speaking, cables and instrument wire bridges related to the reservoir area should be laid along the outside of the fire embankment.

Yes, this is how our factory works. The headquarters safety inspection did not say no.

The cables mentioned by my friend upstairs are often run on the bridges or pipe piers of process pipelines. Occasionally they can be run against the fire embankment, but I have never seen other bridges placed on the fire embankment!

Pipe racks are not allowed to be erected on the protective embankment. They can be crossed, but pipe racks cannot be walked on it. It is best for the host to read more about the regulations.

Pipe racks can be spanned. Generally, brackets are not installed on the fire embankment. There are few pipelines that directly cross the fire embankment.

"Oil Product Storage and Transportation Design Manual Volume 1" P365 states that "Earth fire embankments should not be used as support points for pipelines.； Masonry firebreaks and firebreaks of concrete structures can be appropriately used as pipe support points, but cannot be used as fixed points. ” The process pipeline can pass through the fire embankment, but a waterproof casing must be added at the crossing point, and both ends must be sealed according to relevant regulations.

Thanks for the answers from the people above. I asked if it can be attached to the outside of the fire embankment and supported by a bracket. The bracket is installed on the outer wall of the fire embankment. It mainly carries the signal line of the fire valve, not on the top.

It should not be allowed. Nothing is installed inside or outside the firewall of all the storage tanks I have seen. Besides, the signal line connection is temporary and does not comply with the regulations. The cable bridge can be supported on the ground or the cable can be directly buried.

6.5.9 The fire dike of the oil tank group shall comply with the following requirements: 1 The fire dike should be closed and able to withstand the static pressure of the contained oil and the destructive force caused by earthquakes, ensuring its strength and stability. 2 The fire embankment should be constructed using non-combustible materials, preferably earth embankments. When there is difficulty in soil source, non-combustible materials such as masonry and reinforced concrete can be used to build the fire embankments, but the inner side should be earthed or coated with effective fire retardant coatings. The width of the top of the earth-built fire embankment shall not be less than 0.5m. 3. The calculated height of the vertical oil tank bank fire embankment should ensure the effective volume within the embankment. The actual height of the fire embankment should be 0.2m higher than the calculated height. The actual height of the fire embankment should not be less than 1.0m and should not be higher than 2.2m (both calculated from the road surface or floor outside the fire embankment). The height of the cofferdam of the horizontal oil tank group should not be less than 0.5m. 4 Where the pipeline crosses the fire embankment, it should be sealed with non-combustible materials. It is strictly prohibited to make holes in fire embankments. 5. The site inside the fire dike does not need to be paved, but the site inside the tank group in areas such as collapsible loess, saline soil, expansive soil, etc. should have measures to prevent rain and spray water from damaging the tank foundation. 6. The site inside the oil tank group should have a designed ground slope of not less than 0.5%. The drainage pipes should lead from below the designed ground inside the fire embankment to the outside of the embankment, and drainage and oil blocking measures should be taken. When the annual rainfall is no more than 200mm or the rainfall can be absorbed within 24 hours, there is no need to install a rainwater drainage system in the oil tank group. 7 There should be no less than two pedestrian steps on the oil tank bank fire embankment, and they should be in different directions. Pedestrian steps should be provided on every embankment. 6.5.10 The distance from the tank wall of an above-ground vertical oil tank to the inner slope foot line of the fire dike should not be less than half the tank wall height. The distance from the tank wall of a horizontal oil tank to the slope foot line inside the cofferdam should not be less than 3m. For oil tanks built on the side of a mountain, the distance between the side of the mountain and the tank wall to the foot of the excavation slope shall not be less than 3m. Pipes can cross firebreaks. Personally, I think there are no regulations prohibiting the installation of cable trays on firewalls, but they can be installed.

As we all know, cables are usually laid outside the fire embankment. There are various methods of laying bridges. Some large warehouses even allow cars to drive to the tank area, and they can only enter by using bridges! So this issue actually doesn’t have a clear definition in the specification!

I think this is very common. If the cable tray is laid along the fire embankment, the brackets must be installed along the outside of the fire embankment. Is it necessary to set up a pipe gallery in addition?

Can a trough box be installed on the inner pipe pier of the fire embankment to lay cables?
