PAULSBORO, N.J. (AP) - Officials say residents of a southern New Jersey town should remain inside until further notice because levels of vinyl chloride remain high after a train derailment last week.

A group of state, federal and local officials issued the last shelter-in-place order for Paulsboro at about 6 p.m. Monday and it's still in place Tuesday morning.

It's the longest-lasting such order since Friday morning's derailment. It's not clear when it will be lifted.

About 100 households from the town are free to go outside. They've been evacuated and are staying in hotels outside the borough line.
