Bengaluru: An explosion in a molten plastic paint machine near the underpass of the second terminal of the Kempegowda International Airport caused injury to six workers early Monday, the police said.
According to the airport police, two of the six workers, Ajay Kumar and Siraj are critical after suffering over 40 percent burns.
The others identified as Avinash, Goutam, Prashanth and Nagesh have been admitted to Victoria Hospital. The police said that the workers were using a thermoplastic road marking machine to paint the zebra crossing and signages on the roads leading up to the airport terminal.

The exact cause of the fire is still not known but prima facie investigations have revealed that a "substantial amount" of paint vapour and mist could have been released causing the accident.
"Perhaps storage of paint material, overspray could have drifted into surrounding areas, mixing with the air and accumulating in enclosed or unventilated areas leading to a blast," the police explained, adding that the blaze spread to the underpass in no time.
"Security guards rushed to the spot after hearing the workers' cries and took them to hospital. Firefighters soon arrived at the scene but it wasn't before two hours that they doused the flames," the police said.
