Fire in chemical unit

A fire in a  chemical unit in Udaipur has gutted the unit. In the pictures in the news report in this link, you can see remnants of barrels that have caught fire. Often, plants store chemicals in barrels on roads due to lack of space. This practice is a waiting time bomb. Barrels exposed to heat from a fire can explode violently and  spread the fire rapidly.

Confined space accident kills 7

 The Hindu Business Line has reported a confined space accident in a textile mill in Erode where 7 workers lost their lives. Apparently, the accident took place when maintenance work was taking place in a sunken pit in a ETP, when a valve broke and released poisonous fumes. The would be rescuers ( 6 of them) entered the  pit one by one to rescue the others and died. Please emphasize in your training the importance of rescuers NOT to enter any space for rescue unless they are adequately protected. This incident  is a tragic loss of life

When the back up fails........

 When I was working in Saudi Arabia, the 3000MTD gas based methanol plant was operated with state of the art DCS systems. Just before a planned turnaround, instrument personnel were working with some control room underfloor cables when, by mistake, all power to the DCS displays were lost. It was restored after 30 minutes. The plant parameters were maintained throughout the upset without any safety issue as the controllers in auto were doing their job. However a case study presented in 2012 by Shri KC Tripathy and others of NTPC shows how safety hazards cropped up during "complete and simultaneous DCS failure in two 500MW units"
The case study mentions among other useful learnings, the following:
"All processors (active and redundant) abruptly rebooted at once. Thereby both redundant network & redundant processor concepts of DCS design were defeated".

 Read the case study in this link.

Lessons from NASA astronaut "water in helmet" incident

In July 2013, during a spacewalk outside the International space station, an astronaut reported water entry into his helmet. He was asked to get back only after he made three calls saying the water didn’t appear to be from a drinking bag. Later it was found out that the drinking bag was not the problem and a choked filter was the cause of the leak. The NASA investigation report mentions some of the reasons for the incident as inadequate training, the crew members and ground misunderstanding the severity of the situation, and a (false) perception that any water leak is likely due to a problem with the drinking bag. Do not normalize deviations!

Moving scaffolding near HT cables

In 2012, there was an electrocution incident in China, when painters moving mobile scaffolding contacted a 10000 V electrical line. The CCTV video in this link illustrates the dangers of high voltages. It is graphic and not for the faint hearted. See the video in this link.
