Can pumps be installed within fire dikes (for Class A and B tank areas)?
Thread Content
Do domestic regulations permit pumps to be installed within fire dikes (for Class A and B tank areas)? What do foreign standards stipulate? Thank you all!
It is not allowed; the clear distance between the pump and the storage tank must be more than 12 meters – this is a new regulation
It is possible to find loopholes; if it is a single tank, it can be installed there, considered as an auxiliary device attached to the main unit, with no further specific requirements. The two people upstairs are both talking about tank-group pumps, so distance requirements apply!
Brother upstairs, you can’t take advantage of things like this!
When it comes to fire safety, there must be no attempts to find loopholes
According to petrochemical and construction regulations, pumps for storage tanks in tank farms are not allowed to be installed inside fire dikes. However, there is an exception for liquefied petroleum gas: in tank farms where liquefied petroleum gas is used as fuel, hydrocarbon pumps can be placed inside fire dikes according to the relevant regulations. I’ve never really understood this!
It’s not allowed according to the regulations, but for a foreign project I worked on last year, the pump was located on the fire dike, and it was quite close to the tank area. It seems that it needs to be determined based on the actual circumstances, and the standards cannot be copied blindly. Of course you can handle the fire safety; then nothing will be a problem. Have you ever seen a Class A tank that is only 1 meter away from the main road? Also passed. :L
Regarding fire safety, it doesn’t matter... as long as you’re the boss
I have always been puzzled by this issue: Chinese regulations prohibit standard pumps from being placed within fire dikes. I read a report online stating that Japanese regulations allow such pumps to be located inside fire dikes
I think it’s not allowed. The purpose of a fire dike is to prevent fires from occurring when materials leak; if your pump is located inside the fire dike, an emergency could lead to an even bigger accident
The regulations do not allow pumps to be located within fire dikes
Depending on the specific pump, if it has certain protective measures in place, it can be placed at a certain distance; however, it is generally required to be kept at least 12 meters away
The fire pumps in the tank farm should be located in a pump house.
When it comes to liquefied hydrocarbons, the process of vaporization must be taken into account, which requires minimizing distances; for situations not permitted by regulations, manufacturers usually make adjustments on their own. I’ve seen many similar cases, such as single tanks for ethylene and propylene, and the same approach can be applied in such scenarios. Of course, it’s necessary to first consult with the local fire department. Rules are established by humans, and special circumstances can allow for exceptions
