SAN FRANCISCO (CBS SF) — Fire personnel and PG&E crews responded to the scene of a PG&E manhole that exploded in San Francisco’s financial district Saturday morning, authorities said.

At least one manhole cover dislodged at the intersection of Grant and California streets around 10:15 a.m. because of an underground electrical failure, according to PG&E spokeswoman Jana Morris.

The manhole cover was contained by the casting structure that holds it in place and did not hit any passing vehicles, she said.

When PG&E crews arrived on scene, some smoke was emanating from the manhole, but that smoke had dissipated as of 11 a.m., Morris said.

Investigators from the electrical company were on scene to determine the source of the explosion.

“At this time we don’t know the cause,” Morris said.

Fire crews also remained at the intersection, which was closed to through traffic.

    One of the strangest and somewhat frightening things I’ve see in 61 years happen the early nineties as I walked down Market Street from Gough toward the Van Ness Muni station, as I passed across the street from the Cviic Center Hotel there was a loud explosion and a manhole cover came out of the sky and pounded the street a few yards from where white smoke was coming out of the hole in the sidewalk it had cleared. Any one touched by that flying hunk of iron would have been maimed or killed. What I remember was the force of energy released, enough to send a secured man hole cover flying into the air and the inability to know where or when it might happen again. The Pope could be in his popemobile on his way down Market when this thing comes flying. The power and randomness is not something that anyone who has seen it forgets.
