Local authorities are working on a compensation plan for residents in a community worst hit by the blasts, according to Zhang Chuanjie, an official with the Binhai New Area, where the warehouse was located.

The subsidies are expected to help the residents to take temporary dwellings in the next quarter, Zhang said, adding that it would take a long time for the damaged apartments to be revamped.

Located only about 600 meters away from the blast site, the community had two residents killed and nearly all doors and windows destroyed.

Covering more than 40,000 square meters, the complex accommodates more than 3,100 households in 44 high-rises.

The residents will be allowed into homes to get their property in the following days, Zhang said.
