If dust hangs in the air in sufficiently small particles and sufficient quantities, and if what does is of a substance that is combustible, then not only fire, but significant explosions can occur.Not sure about the explosion but I do remember that an accumulation of dust can cause a fire in some way.
Just before i served on the USS Hancock CVA-19 there had been several fires in heating and AC vents/ducts caused by dust build up.. The ship established a vent cleaning crew to maintain the cleanliness of the vents.
If dust hangs in the air in sufficiently small particles and sufficient quantities, and if what does is of a substance that is combustible, then not only fire, but significant explosions can occur.
This happens now and then in grain silos, and can happen anywhere if the space is confined, the dust particulates get suspended in the air and a spark is introduced.
The most famous example I am aware of was in Texas, City near Houston and Galveston in April 1947 when a vessel carrying amonium nitrate fertilizer, where the captain closed all of the hatches to protect the cargo from a small fire that had broken out in the galley or somewhere else, exploded violently. Glsss was shatrttered in towns up to 40 miles away. 581 people were killed and over 5,000 injured. The town of Texas City was almost completely destroyed. Early the next morning, a second ship, which had caught fire and was also carrying fertilizer, also exploded.
An entire propeller was blown off the 1st ship and found later more than a mile inland. Other parts of the vessels were found at similar distances from the explosion. Google "Texas City Disaster" and look at the images. There are some fairly amazing photos from the incident now over 65 years ago. See the site listed below for more pictures:
Excellent post ^^^
You see the same thing on USN ships. Look in the upper right hand corner of the photo below. If the cables are covered with a vent like structure what happens, believe it or not, dust collects and that is a great fire hazard.
Yes...do. Also, if you get the chance, visit the Battleship Texas. It is a very worthwhile museum that is a great display of World War I era battleship technology.Thanks for that bit of history Jeff. Now the next time I go to Galveston or Texas City for fishing, I'll be sure to look up at those memorials.
Actually Texas was commissioned in 1914 during World War I and saw action in the form of North Sea sorties during that war. She also was pretty involved in the Atlantic and then at Normandy, and then later in the Pacific in shelling enemy positions in World War II. But thanks for pointing out my error, I had meant to classify her in the World War I era, not World War II. I fixed that in my post above.Strictly off-topic:
If you want to see superb examples of pre-WW II battleship technology, you should be looking for USS Washington and North Carolina, neither of which is unfortunately preserved, as far as I know.
The USS Texas is definitely pre-WW I, and not a very outstanding specimen, either.
Thanks. I had wondered if that was true...sounds more and more like it is. IMHO, they should build a fourth to ensure that two different fleets always had one available.There is not fourth Type 071, I do not know if there ever ever will be.
You could maybe surge two at a time, but I highly doubt all three would be available at the same time unless they were all otherwise just sitting at pierside instead of doing the usual patrol/maintenance/training rotations.The PLAN thinking seems to be that three are adequate for the South Sea Fleet. Like that, they can lift the three mechanised battalion groups of one of the two marine brigades at any time.
