The worker accidentally cut a gas pipe that he thought was a drainage pipe, sparking the blaze at the Friendly Garden Apartments on Lynttonsville Road, Montgomery County Fire and Rescue (MCFRS) Chief Scott Goldstein said.
The cut pipe caused an explosion and a fire to erupt. The exact source, however, remains unknown.
The pipes were not labelled and there were concerns about the training of that worker who started the fire, Montgomery County Executive Marc Elrich said. He hoped that making proper adjustments to both these areas could prevent future incidents.
In addition, 12 out of the 14 injured were discharged from the hospital as of Monday. One person remained in critical care, according to Chief Goldstein. Various efforts are still being done to help those displaced by the fire.
