A small explosion occurred in an apartment in Van Nuys, injuring three workers, CBS News Los Angeles reported. The incident took place just before 10 a.m. at 14540 Hartland Street, according to the Los Angeles Fire Department.

The explosion was caused by fumes from chemicals used during work on a single apartment. These fumes are believed to have come into contact with a water heater's pilot light, leading to the blast, CBS News Los Angeles said.
