Design and robustness

 How GE designs its jet engines

The above link is worth watching and it is interesting to see how strict mandates for aviation design are!
Of late, in India, I see a deterioration in design aspects in chemical plants., mainly because of cost cutting pressures and severe competition in the EPC space. This leads to some dilution in design. Let me give you an example. There were two EPC contractors bidding to build a new ammonia storage tank. One of them who was the lowest bidder got the assignment. Tank was erected, commissioned and everything went off well. As time went by, corrosion started affecting the tanks and only then it was noticed that the designer had scrounged on the number of root isolation valves to cut costs. This meant that if there was a leak in an instrument manifold tapping coming from the top of the tank to the bottom, the leak could not be isolated. You might argue that a HAZOP study should have spotted this, but the quality of HAZOP studies has nosedived!

Fatality due to fall in molten iron bucket

News reports indicate that an employee of a major steel company has died after falling into a molten iron bucket which was at 1600 deg C. The investigation will reveal the cause of the tragic incident.

I want to share an incident in another company I heard about few years back, where an engineer fell into a shredding machine that was operating. The fall was due to an open manhole, left open by maintenance. The engineer did not see the open manhole and fell into it. The maintenance crew had taken a break and left without barricading or closing the manhole cover.

Lessons from an air crash

The NTSB's investigation of an air crash at San Francisco airport during landing last year mentions that
"The board’s acting chairman, Chris Hart, warned that the accident underscores a problem that has long troubled aviation regulators around the globe — that increasingly complicated automated aircraft controls designed to improve safety are also creating new opportunities for error. 
The Asiana flight crew ‘‘over-relied on automated systems that they did not fully understand,’’ Hart said. 
‘‘In their efforts to compensate for the unreliability of human performance, the designers of automated control systems have unwittingly created opportunities for new error types that can be even more serious than those they were seeking to avoid,’’ he said. "
Read the article in this link. 

I am a firm believer of keeping it simple. Just because that vendors try to sell you a piece of "latest" technology, do not buy it unless you are convinced it will be useful for you. If the argument is that we need more automation systems as competency is going down, I would answer by saying, keep your systems simple so that your training programs become more effective!

We are like this only........

Recently I was travelling on a highway which is notorious for accidents. The company car which had picked me up had 4 other employees in it. Only the driver and me (sitting in the rear seat) were wearing the seat belts. I finished my work in the company (which has many plants at various locations) and was travelling back with the corporate safety head of the company along with me. He was not wearing his seat belt!! The driver was rash but none objected till I told him to drive safely. Guess you know where the problem is!!
Why are we like this??
