SAN FRANCISCO (CBS SF) — Firefighters in San Francisco were able to rescue a worker who fell into a confined space on a U.S. naval ship in dry dock in the city’s Dogpatch neighborhood.

The adult male victim, who is not a naval employee, was working on the U.S. Naval Ship Guadalupe at a private dry dock facility at 20th and Third streets when he lost his footing and fell 10 to 15 feet, according to fire department spokesman Jonathan Baxter.

Fire officials first reported the incident shortly before 3:30 p.m.

The man has moderate injuries from his fall but is reported to be conscious and breathing, Baxter said.

Firefighters are conducting a confined space rescue, which means that personnel were lowered by rope to the victim and then the victim will be raised back out.

Baxter said the space has no windows or ventilation and will require monitoring to make sure it has sufficient air for both the victim and rescuers.

Shortly after 4:30 p.m., the department tweeted video of the rescue in process as the victim and fire personnel were hoisted up.

Fire personnel were seen taking the victim off of the ship with a gurney via one of the walkways at about 4:40 p.m.

The San Francisco Fire Department PIO Twitter account also posted a humorous clarification in case someone had misinterpreted an earlier tweet.
