While the boiler at ammonia plant burst at around 11:40 am today, district administration Ropar was informed after 40 to 50 minutes of the incidence.
Confirming this, deputy commissioner Priyank Bharti said that even area SDM Lakhmir Singh was not informed immediately after the incidence.
“As per the protocol, the NFL authorities should have informed us within minutes after the incidence. But it took at least 40 to 50 minutes for the news to reach us. Fortunately, there was no ammonia leakage. Had it been a gas leakage, more damage could have been caused and informing us untimely could have added to chaos,” he observed.
However, official spokesperson NFL Naya Nangal claimed that the SDM and DSP were informed within 15 minutes of tragedy.Sources said that injured Umesh Kumar’s timely action of switching off main gas connection helped in saving many lives. Had the ammonia spread around, more losses of life and property would have happened.
The plant, where tragedy struck, was to be closed on Monday for 25 days maintenance practice. Annual target of NFL for urea production was 4. 78 lac tonnes and NFL had already attained 4.73 lac tonnes production.Daily production of ammonia at the plant is 900 tonnes, while that of urea is 1450 tonnes. NFL spokesperson said that company would meet its target with the help of other units. The unit has been shut down three days before the scheduled time due to accident.
Nangal MLA Rana KP Singh too reached the spot. He held the NFL management responsible for this tragedy and demanded a high level probe. He said that the fire fighting equipments at factory were not up-to-date. SSP L K Yadav asked people not to panic as the accident was result of some technical failure.
