Do the motors, pumps, and other equipment located inside the protective dike of the oil tank area have to be moved outside the dike?

Do the motors, pumps, and other equipment located inside the protective dike of the oil tank area have to be moved outside the dike? Some time ago, I saw oil transfer pumps and motors inside the diesel containment dike of an oil depot. Is such an arrangement in line with safety requirements?
It should be done outside the dike; we have already made corrections some time ago.
In accordance with the requirements of the Code for Fire Protection Design of Petrochemical Enterprises GB50160, it is not allowed to be located within a fire dike.
It’s the same as here; I really don’t know what they were thinking. They are now carrying out repairs, but during those repairs I noticed that motors and submersible pumps have been installed inside the zero-level trench cofferdam. It’s unbelievable. .
In accordance with the requirements of the Code for Fire Protection Design of Petrochemical Enterprises GB50160, it is not allowed to locate such facilities within fire dikes, and all design institutes follow these regulations when carrying out their designs.
According to GB50160 requirements, it is not allowed to be installed within a fire dike.
Of course it’s not allowed; it must be located outside the dike. Our company just completed the necessary adjustments for that recently
I have that impression. It is not allowed to put it inside. But I’ve forgotten which specific standard it is
There are regulations prohibiting it from being placed inside the embankment.
May I ask which article in the building codes addresses the owner’s question? Why can’t I find it?
This is clearly stipulated in the Code for Fire Protection Design of Petrochemical Enterprises: pumps, alarm devices, etc., cannot be installed within the cofferdam. So this definitely has to be moved.
After moving outside the dike, if one is in an environment with explosive gases, electrical equipment must also be of the explosion-proof type.
GB50058 sets requirements regarding wiring, but it’s impossible to have no electrical equipment inside the fire dike – for example, combustible gas detectors are useless if they’re not installed there.
It is not allowed to be installed within a fire dike.
Yes, it must be moved out; otherwise, safety regulations require it!
GB 50160—99 \"Code for Fire Protection Design of Petrochemical Enterprises\", Section 2: General Layout of the Plant – Note (9): The dedicated pumps (or pump houses) for tank groups shall be located outside the fire dike. The fire separation distance between them and the tank groups should be no less than 15 meters for Class A and A1 materials； For Class A B and Class B, it should be no less than 12m ； For floating roofs and Class C tanks, the height should be no less than 10 m (for tanks with a volume of 500 m3 or less, it should be no less than 8 m). According to GB 50160—2008 \"Code for Fire Protection Design of Petrochemical Enterprises\", clause 5.2.22 states that the layout of the tanks (groups) in a plant shall comply with the following requirements: 1 When the total volume of the tanks in the plant is such that liquefied hydrocarbon tanks have a volume of 100 m3 or less, and tanks holding flammable gases or liquids have a volume of 1000 m3 or less, these tanks can be located within the plant; the fire separation distance between these tanks and other equipment and buildings shall be no less than the values specified in Table 5.2.1. 2 When the total volume of the storage tank group in the facility is: for liquefied hydrocarbon tanks, it is greater than 100 m3 and less than or equal to 500 m3; for flammable liquid tanks or flammable gas tanks, it is greater than 1000 m3 and less than or equal to 5000 m3, such tanks should be arranged together at the edge of the facility ； However, the volume of a single tank for liquefied hydrocarbons should not exceed 300 m3, and the volume of a single tank for flammable liquids should not exceed 3000 m3. The fire protection design of the plant’s tank farm shall comply with the relevant provisions in Chapter 6 of these specifications, and the pumps and machinery related to the tanks shall be located outside the fire dike. The fire separation distance between the unit’s storage tank group and other equipment and buildings within the unit shall not be less than the values specified in Table 5.2.1.

It should be improved; we have already carried out similar projects
I once conducted a safety assessment for a methanol project, which involved placing pumps and motors within the tank area; the report was only issued after corrective actions were taken
Facilities such as motors and pumps can generate sparks due to issues like damaged insulation, posing a danger; they should be moved outside the protective barrier.
It is not allowed to install mechanical pumps inside fire dikes, as the likelihood of combustible gases appearing there is higher than in other areas.
