The multi-storey plastic manufacturing factory had caught fire and collapsed on Monday, killing 13 people, including six firemen.

The rescue operation by a team of the 7th battalion of National Disaster Response Force (NDRF) continued on the fourth day today.

NDRF squad leader Deepak Kumar said he could not say at this point how many more days the rescue operations would continue.

“We want to complete our job at the earliest, but we are facing so many problems,” he said, adding eruption of fire at some spots because of chemicals inside the factory was posing a problem in the rescue operations.

Three houses and two factories located adjacent to the plastic factory had also got damaged because of the impact of the incident, the official added.
