Title: Big explosion in west texas, anyone there?

Looks like a fertilizer plant cooked off.

I know where it is and have driven through there a couple of times.

You think it was ammonium nitrate, or natural gas?

At least 10 structures are on fire in the town, including a school which is next door to the plant.

The town's community hospital is about four blocks from the burning fertilizer plant.

Great community planning there, folks.

Huh...  Wondered what that was.

Local nooz drove down there and sent their helicopter.  Looks like all of central Texas sent their emergency vehicles, 'cause there aren't that many red lights in the whole county.  Bunch of buildings flattened and half the country is on fire. Pretty huge fustercluck.

And now they're evacuating the town in case there's a second explosion.  Seems like the mushroom cloud and resulting hellacious fire would've dealt with the combustibles, but they must know something I don't.

I live about an hour from West, and we felt the explosion here. I was with a friend at our small church. It felt like someone closed a door really hard. We went outside to check for unexpected visitors. Didn't know about the explosion until I got home. Know a few co-workers who live in West....all OK, thank God.

Good coverage on this on 

www.kwtx.com
www.wacotrib.com

Now reporting as many as 70 dead....

Town I grew up in has an ammonium nitrate plant.  They located it a good five miles north of town, and even then there was speculation that if it went off the explosion would break every window in town.

The second tank still has a fire nearby. They're keeping away from it in case it explodes, too.

Well, the Pepcon plant in Nevada had several successive explosions:

Slightly off topic:

While I sympathize with the tragic loss of life (especially the emergency workers) and housing, the first thing I noticed was that the article cited above...

http://www.wfaa.com/news/texas-news/powerful-exploson-rocks-town-north-of-waco-203508001.html

.... was a pretty good example of classic reportage.  Who, what, where. when.  A lot of prominent journalists today could take a lesson from that.

Place is a little more than halfway between Austin and Dallas, making it a good hour and a half, maybe hour and 45 minutes drive north of where I'm at along I-35 - too far away to hear or feel the explosion from here.

News reports are sketchy, but earlier they were saying over 100 injured and "between 5 and 15" feared dead, with some VFD crew members "unaccounted for."

Overnight a south wind was keeping the smoke plume blowing north, but by 7 it was already changing direction as a line of storms and a cold front were coming through. Haven't seen an update for a couple of hours . . .

If the one in my town had caught fire, I'd have probably watched it...from the top of the mountain on the opposite side of the valley a good 10 miles away, and I'd have made sure I was standing near something substantial to duck behind.

Really? It does to me. I work in an industrial area and make it a point to know what is in and the potential blast radius of all the stuff around me.

Maybe I'm projecting my knowledge of boomy things, but I really thought that everyone know that kinda of thing goes big when it goes.  This isn't the first fetilizer plant to go boom.

Same here.  Closest place that uses volatile chems in quantity are about 2 miles from the house.  Not worried because the quantity is small relative to say a fertilizer plant.

No reason for gov't to step in here.  I would bet dollars to donuts the plant predates the surrounding structures.  Property owners knew of it and were OK with the risk.  And most will end up OK.  Some, not so much.

There was a pretty good KB at a chemical plant near Waxahache a year or two ago.  Roasted a fire truck, IIRC.  Luckily it was outside of town.

I guess Camera Guy missed the news that day.  Potential for boom = GTFO.  I can't imagine living in the apartments across the street and not bailing at the first sign of smoke.  Drive to Waco, have dinner at Ninfa's, and hope the house is there when you get back.

I have read about the Texas City Disaster.  Here is another scary one: http://en.wikipedia.org/wiki/Cleveland_East_Ohio_Gas_explosion

TL ; DR  1944 LNG (Liquefied Natural Gas) tank leaks and the vapor gets into the sewer lines and mixes with air and sewer gas and finally ignites.  After the first explosion the onlookers return to their homes and there is a second explosion from another leaking tank leveled the tank farm and then the underground explosion continued.
Quote
However, the explosions and fires continued to occur, trapping many who had returned to what they thought was the safety of their own homes. Housewives who were at home suddenly found their homes engulfed in flame as the explosion traveled through the sewers and up through drains. The following day, Associated Press wire stories contained quotes from survivors, many of whom were at home cleaning in preparation for the coming Sabbath. Survivors said that within a split second after the explosion, their homes and clothes were on fire.

Found out this am that two former coworkers are ok. They live in West and were assisting in the evac. of the nursing home. They were just outside the destruction zone when blew. Were up all night searching homes. As I understand the homes, nursing home and apartment complex had been evac before it blew.

An article I saw said that the plant owners were asked about the possibility of an explosion during the planning process and they stated flat out that it "could not" explode. Based on that, I would have to conclude that the property owners did not know of it and were not okay with the risk.

Slow-mo of a phone vid.

http://www.youtube.com/watch?v=qVzz8NylTwM

From the frame or two prior to the full explosion it looks like the ignition point was slightly away from the main fire, somewhere in the combustion gas column.  I wonder if there was a chlorine source somewhere in the immediate vicinity.  When ammonia gas is exposed to chlorine in high enough concentrations you get nitrogen trichloride, which is some pretty nasty stuff.

In one of the post-explosion cellphone videos, residents speculated that it was a plane crash.  Seems like a reasonable assumption, given the information they had at the time.  I suspect plane crashes account for a large percentage of cornfield-based fiery explosions.  I think I might have made a similar guess with limited information.

Missile strike would have rated a bit lower on the probability scale, but I did turn the shiny side inward by accident.   [tinfoil]

Last I heard was the firefighters putting water on the fire may have triggered the explosion.

11 of the 14 dead were volunteer emergency responders.

They need to build statues or name high schools after them.

If they hadn't got the area mostly evacuated, the death toll would likely have been in the triple digits.

??? You fight anhydrous fires with water just like any other fire.  Who is saying it may have triggered the explosion, and why?

Does anyone know if they had a pile of AN laying around?  Even forty or fifty tons of that laying around during a fire would be... bad.

my organization works very closely with Dallas Fire & Rescue. I never met him, but office-mates worked with Kenny Harris, the Captain who lived nearby and went to assist.

Rest in peace, Captain, with the other brave souls who went after the fire that day.

Not really sure what the reported issue is but have heard more than once about water mixing with something at the plant makes a violent gas. Some of the locals are kinda pissed about these statements. They were doing the best that they could. You would think that if they were doing something wrong the firefighter from Dallas that was on the scene and died could have stopped or redirected the efforts. Just keep in mind that this is not an official report via the news. Just things heard from those that know people in the area.

It is very possible that there was another chemical there that mixed with the water and created an explosion. We don't know everything about a scene while we are on it, especially something that you might never even see until you find out later about it.

Also this could have happened:

Never apply water to a large pool of liquid ammonia. Pools of ammonia will autorefrigerate to 28 degrees below 0. Applying relatively warm water will increase the vaporization of ammonia by raising its temperature.

Water Use

Applying water is the most effective tool to fight an anhydrous ammonia release. Before the decision is made to aggressively attach the release many factors must be reasoned through.

Staging water upwind of a potential ammonia releaseVehicles must approach carefully from up wind or from the side. It is difficult if not impossible to drive across a freshly plowed or muddy field with fire truck apparatus not to mention hauling water out to the site of an ammonia release.

Having enough water is vital. As a rule of thumb, 100 gallons of water is needed for every gallon of product released. A 500-gallon apparatus will only allow a few minutes of support. A long-term sustained attack will require lots of water and in rural locations this means shuttle operations.

If a fire is impinging on the ammonia tank the pressure relief valves must be working properly. Keep the tank cool by applying water on its shell.

Never apply water to a large pool of liquid ammonia. Pools of ammonia will autorefrigerate to 28 degrees below 0. Applying relatively warm water will increase the vaporization of ammonia by raising its temperature.

Before applying water, work with the managers to determine where runoff will flow or pond. A simple earthen dike will contain the ammonia contaminated water for later recovery and disposal.

Using Water to Approach and Secure the Source of an Ammonia Release

    Fog streams provide a protective curtain for a safe approach to the source.
    Attack using 2, 1½ inch lines. Consider additional lines if available.
    Both lines should apply 95 gallons per minute with 100 psi at each nozzle end. (? minutes * 2 lines * 95 gallons = amount of water needed)
    Attack crew should consist of 5 members. A crew leader flanked by a nozzle person and hose handler on each of the leader's sides. All on supplied air.
    The crew leader should be wearing ammonia rated gloves. All must be on supplied air (SCBAs) and enough air must be available.
    Rotate nozzles applying maximum flow with the widest fog pattern.
    Angle your approach to avoid high downwind concentrations.
    A rapid high and wide rotation is more effective for ammonia absorption.
    Nozzle end holders should rotate in unison like the wheels on a bike.
    If a line fails or crew member develops skin irritation evacuate immediately and reassess.
    Narrow sweep when closing in on source.
    Avoid pools of ammonia.
    Force vapors down to the ground
    Narrow fog sweep significantly as you close in on source.
    Crew leader reaches to valve and tightens it stopping flow.
    Decontaminate crew members with water prior to leaving scene. k

Heard on the news this am that there was 54k lbs :O of ammonium nitrate on site. Also heard that if they had more than 400 lbs requires reporting to the feds. If the reports are true that the volume had not been reported, plant owner is toast.

We have one truck that can put out that kind of flow.  Trouble is that is so slow that it might be next Tuesday before it gets there.  Better give us 24 hours notice before you're planning to have an incident.

I think those guidelines are for a leaking tank, not an entire plant on fire.   =|

I'm not sure if anybody even uses ammonia around here.  Pretty much just hay and livestock.

Watched one news report with before and after aerial video.  Before shot showed covered, open front structure with many ton piles of AN inside.  After shot showed structure was gone, large crater in its place.  Hmmm...
