Process Safety - Another day, another blast!

On Good Friday, another blast occurred in a refinery in the USA. The CSB will be investigating the incident but it appears that the CSB is now having its hands full with its investigators currently investigating other incidents. If this is the trend in the USA where PSM is mandatory, we must be very careful in India!

"A Washington state oil refinery hit by a deadly blast and fire early Friday was recently fined for safety violations amid what federal watchdogs call a troubling trend of serious accidents at refineries.
Three men died at the scene and two women died later at a Seattle hospital. Two other men were hospitalized with major burns over the majority of their bodies. It was the largest fatal refinery accident since a 2005 explosion at a BP American refinery in Texas killed 15 people and injured another 170.The Good Friday holiday blast rattled windows more than a mile away and has the most recorded fatalities since 15 workers were killed in a BP Plc incident in 2005 at that company’s Texas City, Texas, operations.
The Tesoro incident occurred as members of a seven-person crew were cleaning a heat exchanger in a unit handling naphtha, a volatile liquid chemically similar to jet fuel, Westfall told reporters.

The blast shook houses and woke people miles away, shooting flames as high as the refinery’s tower before the blaze was extinguished about 90 minutes later.
The blast occurred in a unit that was in the dangerous process of returning to operation, turning up heat and pressure, said Tesoro spokesman Greg Wright".

CSB Chairman and CEO John Bresland said, “The CSB has eighteen ongoing investigations. Of those, seven of these accidents occurred at refineries across the country. This is a significant and disturbing trend that the refining industry needs to address immediately.”
