A sudden manhole blast jolted Lincoln Road on Sunday night, sending flames into an electrical vault and leaving three people with minor injuries before they were taken to Mount Sinai Medical Center. Neighbors said they heard a deafening boom and watched windows shatter as firefighters rushed in, cleared the building near 230 Lincoln Road and shut down nearby streets. Officials said the injured are expected to recover.
Miami Beach Fire Department officials said a manhole fire triggered an ignition inside a Florida Power & Light Company electrical vault in an adjacent building near 230 Lincoln Road. Florida Power & Light cut power to the surrounding area while emergency crews moved in, and firefighters were able to contain the blaze, according to WSVN. The building was evacuated, police closed off streets around the scene and three people were transported to Mount Sinai Medical Center with minor injuries. Officials said those patients are expected to be okay.
Why underground vaults can be dangerous
Manholes and electrical vaults pack a risky mix: energized cables, tight quarters and, in some cases, gases or materials that can ignite or explode if something goes wrong with the equipment or water gets in. Federal safety guidance treats these spaces as confined or permit-required areas that must be tested for hazardous atmospheres, ventilated and secured through lockout/tagout procedures before anyone goes inside, according to the U.S. Occupational Safety and Health Administration. Laboratory safety manuals echo that approach, calling for atmospheric monitoring, ventilation and strict entry controls in underground utility vaults to help prevent explosions and protect responders.
Neighbors and the scene afterward
Bystanders described a sudden, violent blast followed by fast-moving flames. “I just heard this loud explosion,” one witness told reporters, while another recalled “a lot of flames coming out” as people scrambled out of the building, according to WSVN. Fire crews ultimately contained the blaze as investigators worked the scene Sunday night and Miami Beach Police kept watch around the evacuated building.
The cause of the manhole fire and the ignition inside the electrical vault remained under investigation. City and utility officials have not released further details on what sparked the blast or when the closed streets might fully reopen.
