Incident due to nomalization of deviation

Operators used to routinely try to clear blockages in an asphalt line by heating the line externally with a propane torch. In this incident, this normalisation of deviation turned into an incident when it caused an explosion in the tank. Read about the incident in this link.

Readers response to post

Mr M.K.Rao, Executive Director of India Glycols responded to my post "Of Mimic panels and Video walls - back to the past?"
His reply is as follows:

"The subject Blog item is interesting and highly relevant too.

When I entered the DMT control room (IPCL, Baroda) in the year 1981, the scene was similar. The space above the pneumatic controllers had a mimic panel that depicted the complete PFD. In addition, we had a model of the entire plant on a large table in the same control room at a corner. It made learning faster and we used to have a better feel of the process. It was easier to know what was going on at a glance.
 

Going by the best of Past & Present, I feel a combination of
  1. DCS work stations
  2. Mimic panel representing the complete/ continuous PFD like in the past (Instead of Video panels – which may appear broken)
  3. A model (physical) of the plant right in the control room would help"

I agree with his valid suggestions and thank him for responding..
