Tank design standards

I often see tanks not being given their due importance by process engineers when modifications are being carried out. Many modifications are done without the use of proper engineering standards. A tank failure can be catastrophic and a good article mentioning the basic precautions and standards to be followed is available in this link.

Bromine gas leak incident

Thanks to Abhay Gujar for sending news about a bromine gas leak. The Times of India reports that "Over 150 people needed treatment and three are in intensive care after bromine gas leaked from a pharmaceutical company in Dombivli's MIDC and spread over a 1-km radius area affecting over 2.5 lakh people. Anger and fear are frothing in the surrounding settlements as this was the fourth instance of carelessness with chemicals that has imperiled people in the industrial area in the past two months".

Top management competency and process safety

I often interact with senior management regarding process safety issues and what I see presently troubles me. Over the years, the senior management in many chemical industries have gradually changed from hardcore chemical engineers and well experienced in plant operations and maintenance to those without a chemical engineering background and plant experience (finance and commercial background). Now this should not be a problem as long as the factory heads are in a position to assert their requirements in process safety and obtain the budgets necessary. But there is also a decline in the competency of factory heads in many units. The disease seems to be spreading and many future accidents are going to be attributed to this.
I don't know if there is a solution to this!
I would appreciate feedback from readers on how this works in their organization. You can mail me at bkprism@gmail.com
