Transformer explosion closes off Embarcadero

SAN FRANCISCO

The San Francisco Fire Department sent carbon dioxide specialists along with firefighters and paramedics to the blown electrical transformer on the Embarcadero near Pier 3 minutes after a 8:27 a.m. call, a dispatcher said.

No one was injured, but part of the road on the Embarcadero near Pier 3 was closed to traffic.

Transformers, which reduce high energy to lower levels, blow often, but this one is underground instead of on a power line or above ground, the dispatcher said.
