A major fire at ONGC's Uran plant killed four people on Tuesday and also highlighted the firm's alleged negligence towards the residents of the adjoining villages. The villagers were trapped inside their houses as the blaze spread to the nullah, which carries hazardous chemicals along with storm water from the ONGC and flows through the surrounding villages.

Three Central Industrial Security Force (CISF) officers — N A Nayka, S Paswan and S Khushwaha — are among the deceased. The fourth victim has been identified as ONGC's resident production superintendent C N Rao.
