BEIJING — An explosion at a chemical plant in Shandong Province late Monday night killed at least one person, according to a Chinese news media report.

The fire had been extinguished by early Tuesday, and officials were investigating the cause. Industrial explosions in China have come under more scrutiny since the recent Tianjin disaster.

On Monday, officials in Tianjin said the explosions there on Aug. 12, set off by hazardous material in warehouses near the port of Tianjin, had killed at least 158 people and resulted in the hospitalization of 356 others. The dead included 94 firefighters, 11 police officers and 53 civilians. About 15 people remained missing.

An investigation by The New York Times showed that Rui Hai International Logistics, the company that was storing the chemicals, had exploited weak governance in Tianjin and used political connections to avoid scrutiny.
