Process safety and fatigue

It is disturbing to note that fatigue probably played a part in the new US power plant explosion that occurred when lines were being blown with natural gas. It appears that one of the victims who died in the explosion was working 12 hours a day, seven days a week, for six months. If operators are being allowed to work without break even in the US, imagine the plight in India!The pressure of commissioning a plant to meet target deadlines often result in people working overtime. With more and more activities being outsourced, industry must be careful that this problem is tackled to avoid incidents. What is more worrying is that the aviation industry in India is reporting incidents of pilot fatigue due to inadequate rest periods.If it can happen in the aviation industry, it can happen in the chemical industry too!
