Share your incidents!

I thank readers of this blog for their continued support. I request readers to send in short descriptions of process incidents they know, to me at bkprism@gmail.com for publication in the blog. I will give the reader credit for the input. The company's name need not be mentioned.Thanks in advance!

Enforcing Process Safety Management

I always wonder that even in the US where PSM is mandatory and companies face stiff fines, there are always violations taking place. Recently OSHA has proposed to fine a seafood company a total of $279,000, for deficiencies in its process safety management program. "The inspection identified other PSM hazards that resulted in 12 serious citations, with $84,000 in proposed fines. These conditions included failing to update process safety information, conduct an incident investigation of a January 2001 ammonia leak, certify or evaluate the PSM program every three years as required, establish and implement procedures to maintain changes in the process, and provide and document employee training".

Engineering control to avoid deaths

The recent train accident at Sainthia station when a speeding train rammed into a stationary one,has raised many questions.An excellent article in Forbes India magazine describes the various engineering controls that are available to prevent such accidents. The article mentions that "There is a range of technological solutions that can remove the scope for human error and make the system fool-proof. The Indian Railways have experimented with a range of solutions to improve its safety record, but none of them has been scaled up nationwide either due to the lack of budget or simply because the powers-that-be had other priorities. When asked, a senior executive in the Indian railways, in charge of technology implementation, prefers to maintain a stoic silence on the issue. Former railway officials, however, are far less sanguine. “The job must be ruthlessly done and the management must not shy away from shedding blood,” says a former Chairman Railway Board who did not wish to be quoted".
In the chemical process industry also, I observe many cost cutting initiatives affecting engineering controls. As long as nothing happens, nobody dies!

The MSDS of Para Toluene Sulfonyl Chloride which was reportedly stored in the tank, indicates that it is water reactive. Read the MSDS in this link.

Safety valves and runaway reactions

I was participating in a HAZOP study of a reactor where a runaway reaction was possible.There was a serious discussion about the reaction kill system, when one of the participants asked what the operators will do if a runaway reaction occurs. The operations chief who was participating immediately answered - run away!He had witnessed an actual runaway reaction in which the reactor started rumbling, gaskets blew, safety valve lifted,and the operators ran away. Know the design basis of your safety valves. This is important for management of change and for writing operating procedures.
