Vacuum cleaner may have caused $400 million fire on nuclear sub
Source: Associated Press
KITTERY Preliminary findings from Navy investigators suggest a fire aboard a dry-docked submarine started in a vacuum cleaner used by shipyard workers, officials said Wednesday. The Navy also confirmed a preliminary estimate of $400 million for repairs.
A statement from the Portsmouth Naval Shipyard said the vacuum was used by workers to clean up after each shift and was stored in an unoccupied space when the fire started.
The repair cost estimate allows the Navy to begin lining up funding.
The Navy estimated that an additional 10 percent cost or $40 million more would be needed to account for disruption to other planned work across all naval shipyards and for potential assistance from private sector contractors, the shipyard said.

Maybe we could have a bake sale or something to help out.

(8,747 posts)Vacuum up extremely fine material, especially particles that were electrically conductive, like metal shavings, this material may have been too small to be trapped by the filter or bag, and passed through and caused a short in the vacuum motor. This could have started the fire, and since ships and submarines are full of flammable material this could have resulted in the fire spreading like it did.
For example, in a business environment, you can't use a conventional floor or canister vacuum to vacuum up spilled laser printer / copier toner. The toner particles are too small and will go right through the filter or bag, and being electrically conductive can short the motor.

I'm not disputing your guess; just wondering.
I was thinking that somehow the workers had vacuumed up some slag left over from welding. The bits were still hot and caused adjacent dust in the bag to ignite. I'm am led to think this by the many house fires I hear about every winter caused by ashes being left in a grocery bag or trash can. The residents think that the ashes are cold, but there's this one warm cinder in the bag they don't know about.
Thanks for the plausible method by which this could have occurred.

(8,747 posts)Laser toner particulate size is 8-10 micrometers, so theoretically a vacuum with a HEPA filter SHOULD catch the toner. But....
Then there's this: http://en.wikipedia.org/wiki/Toner
If they were using an ordinary household vacuum, with all the plastic parts, as opposed to some sort of specialty vacuum, like a shop vac with a metal dust container, that could have caused it. I did not think of the dust explosion theory.
And I like your idea of welding slag causing the fire, I didn't think of that, either.

(12,660 posts)Tool boxes, welding machines, test gear, collected trash - all had to be hauled off every day. We had to sweep and clean, and empty all trash collecting devices that would be left on the ship - including ship's cleaning items that we might be useing, such as trash cans, mop buckets and vacuum cleaners.
We were required by contract to keep the ship area we were working in clean and the only things we were allowed to leave on the ship unattended after our work shift was cable we might be in the process of running, test gear that was still running overnight tests, bypass gear, or the hardware and equipment we were installing.
Sounds as if it were a shipyard issue.

Man ... what an imperfect, flawed piece of everyday technology.
Every review, every conversation, every report on vacuum cleaners reveals something wrong with their operation.
In the 21st century it is amazing that no one has apparently constructed a reasonably-priced vacuum cleaner that works reasonably well for at least three or four years.
So, frankly I'm not surprised that it was the vacuum cleaner's fault.
(Of course, if someone knows of good vacuum cleaner, let me -- and the Navy -- know right away.)

(60,567 posts)A lot of it is made of plastic resins, and it's starting to deteriorate.
But it does a terrific job in cat hair and dander.

(8,747 posts)I've been using for 10 years. I don't have pets, but it's still a great vacuum.
My tips:
(1) Get a bagless vacuum, no question.
(2) When you buy the vacuum, buy an extra belt and one extra of each filter.
From everything I've read Dyson is the best out there. Expensive, but the best. Of course you can buy 2-4 cheaper vacuums for the price of one Dyson.

So find the operator and sue them, too.

(33,982 posts)There's all sorts of volatile, and flammable material you'd never find in a residential home.
More than likely, the shipyard will be sued. So that's covered.

We probably won't be suing ourselves.

My quick search didn't reveal any widely known issues with cordless appliances, but appliance fire stats are rather disturbing considering that only half of appliance fires are attributed to human error, animals, or storms.
"The Consumer Product Safety Commission, using estimates from 2006 through 2008, says that major appliances caused more than 150,000 residential fires each year, resulting in 3,670 injuries, 150 deaths, and $547 million dollars in property damage."
"More than 15 million appliance units have been recalled in the past five years for defects that could cause a fire, according to our analysis of CPSC records, with 1,942 incidents reported. Almost half of the recalled units were dishwashers, and the CPSC told us that it is investigating the problem."
