Weak Sulphuric acid FRP tank collapse

In a factory, where 10 MT weak sulphuric acid was stored, suddenly the suction line valve tank nozzle assembly got broken and through this opening sulphuric acid drained out from the tank. This resulted in vacuum formation in the tank. This FRP tank hit against the supporting channel legs due to the formation of vacuum.
Causes :
1. The FRP tank was not maintained with a adequate strength and stability

2. The FRP tank was not tested and certified by the Competent person every year
