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

To facilitate repair works to be carried out to a grizzly bar, two metal rods were placed above the grizzly bar and this was covered by a tarpaulin sheet.Right below this arrangement welding of grizzly bar was carried out. When the welding process was being carried out heavy lumps of urea started falling down from the prill tower and fell on the iron plates placed over the grizzly bar. The iron plates along with heavy lumps of urea fell on the workers working right below the covered tarpaulin sheet and they sustained head Injuries and died.

Management of Change or Change of Management?

In 1999, when I was carrying out a PSM audit, we were auditing a maintenance mechanic. I was asking whether he can explain what is the meaning of management of change. He replied that when his company was recently taken over by another company, that is management of change!
Are you carrying out MOC for change in Management?
