Worst ever U.S. industrial accident, 1947: 576 dead

April 16 marks the 60th anniversary of the Texas City Disaster. A large cargo ship being loaded with tons of ammonium nitrate caught fire and exploded, setting fire to other nearby ships, one of which exploded, and devastating much of the town. In all, 576 people died in Texas City on April 16 and 17, 1947.

The incident also produced one of the most famous tort cases in U.S. history, Dalehite vs. United States, 346 U.S. 15 (1953). (Here is the Findlaw version, subscription required.)

The entire Texas City fire department was wiped out, 28 firefighters in all. The International Association of Fire Fighters, Local 1259 has a website dedicated to the history of the disaster, with a collection of some powerful photographs.

More below the fold.

It was a creeping disaster, starting with fire aboard the Grandcamp as it was being loaded, including fires aboard at least four vessels by day’s end, two massive explosions, a tsunami, and fires across the city as a result of raining debris. Here is part of the explanation from the IAFF Local 1259 site:

Around 9:00, flames erupted from the open hatch, with smoke variously described as “a pretty gold, yellow color” or as “orange smoke in the morning sunlight…beautiful to see.” Twelve minutes later, the Grandcamp disintegrated in a prodigious explosion heard as far as 150 miles distant. A huge mushroom like cloud billowed more than 2,ooo feet into the morning air, the shockwave knocking two light planes flying overhead out of the sky. A thick curtain of steel shards scythed through workers along the docks and a crowd of curious onlookers who had gathered at the head of the slip at which the ship was moored. Blast over pressure and heat disintegrated the bodies of the firefighters and ship’s crew still on board. At the Monsanto plant, located across the slip, 145 of 450 shift workers perished. A fifteen-foot wave of water thrust from the slip by the force of the blast swept a large steel barge ashore and carried dead and injured persons back into the turning basin as it receded. Fragments of the Grandcamp, some weighing several tons, showered down throughout the port and town for several minutes, extending the range of casualties and property damage well into the business district, about a mile away. Falling shrapnel bombarded buildings and oil storage tanks at nearby refineries, ripping open pipes and tanks of flammable liquids and starting numerous fires. After the shrapnel, flaming balls of sisal and cotton from the ships cargo fell out of the sky, adding to the growing conflagration.

Some descriptions say the sisal rope in some places resembled a massive spider web across the city. The disaster wasn’t over, yet — for another half day ship fires would rage leading to a second explosion; again, from the IAFF Local 1259 site:

The horror was not over yet. As help poured into Texas City, no one gave much thought to another Liberty ship tied up in the adjoining slip. The High Flyer was loaded with sulfur as well as a thousand tons of ammonium nitrate fertilizer. The force of the Grandcamp’s explosion had torn the High Flyer from its moorings and caused it to drift across the slip, where it lodged against another vessel, the Wilson B. Keene. The High Flyer was severely damaged, but many of its crew members, although injured, remained on board for about an hour until the thick, oily smoke and sulfur fumes drifting across the waterfront forced the master to abandon ship. Much later in the afternoon, two men looking for casualties boarded the High Flyer and noticed flames coming from one of the holds. Although they reported this to someone at the waterfront, several more hours passed before anyone understood the significance of this situation, and not until 11:00 P.M. did tugs manned by volunteers arrive from Galveston to pull the burning ship away from the docks. Even though a boarding party cut the anchor chain, the tugs were unable to extract the ship from the slip. By 1:00 A.M. on 17th April, flames were shooting out of the hold. The tugs retrieved the boarders, severed tow lines, and moved quickly out of the slip. Ten minutes later, the High Flyer exploded in a blast witnesses thought even more powerful than that of the Grandcamp. Although casualties were light because rescue personnel had evacuated the dock area, the blast compounded already severe property damage. In what witnesses described as something resembling a fireworks display, incandescent chunks of steel which had been the ship arched high into the night sky and fell over a wide radius, starting numerous fires. Crude oil tanks burst into flames, and a chain reaction spread fires to other structures previously spared damage. When dawn arrived, large columns of thick, black smoke were visible thirty miles away. These clouds hovered over Texas City for days until the fires gradually burned out or were extinguished by weary fire-fighting crews.

The disaster occurred shortly after the enactment of the Federal Tort Claims Act (FTCA), which detailed how and when citizens could sue the government for injurious actions. Many people sued, including Elizabeth Dalehite, suing for wrongful death of her husband Henry Dalehite; at least 300 separate suits were consolidated into the Dalhite suit. Texas district federal courts determined the federal government was liable on several grounds (the ammonium nitrate was bound for Europe as part of the post-World War II reconstruction process); on appeal, however, the Supreme Court determined that various negligent acts by government decision makers did not make the government liable, since the negligence was in the planning of the processes, not in the execution, and planning negligence is immune from liability.

The case established that breaking through governmental immunity would be difficult even under the FTCA (an issue I dealt with in the radiation compensation issues three decades later). Notably, by the time the case got to the Supreme Court, a young attorney named Warren Burger was Assistant Attorney General for the U.S. , supervising the Civil Division of the Department of Justice. Burger appeared in court on behalf of the United States. Three years later President Dwight Eisenhower appointed Burger to the U.S. Court of Appeals for the District of Columbia Circuit where he sat for 13 years, until President Richard Nixon named him Chief Justice of the Supreme Court in 1969.

The Texas City disaster gets only brief coverage in most Texas history texts (there is no mention in Texas Essential Knowledge and Skills (TEKS)). Neither do other disasters get much coverage, such as the Galveston hurricane of 1900 (between 6,000 and 15,000 dead), the New London School explosion of March 18, 1937, nor the famous 1957 Dallas tornado. The Dust Bowl was a longer-running disaster, and is covered, but not in so much depth as I would like. Without being too macabre, a Texas history teacher could make the course considerably more interesting, and perhaps relevant, with reference to these disasters and how they shaped the Texas psyche.

Disasters expose the errors and mistakes humans make in developing our modern world.  Often, they point out serious problems in government institutions, and they provide opportunities for heroes to rise to superhuman tasks.  The Texas City Disaster should be part of the core knowledge of all Texans.

  2. Ed Darrell says:

    Okay. At some length, I see the issue Moon Warrior wrote about.

    The ship is known as S.S. Grandchamp in about half the histories, and S.S. Grandcamp in others.

    “Grandcamp” in French can be pronounced as “Grandchamp” in English. Google it, and you’ll find accounts of the disaster under both spellings.

    Oy, the issues that screw up straight history research!


  3. Ed Darrell says:

    The ship I’m referring to is the Grandchamp. See the court case on it.


  4. moon warrior says:

    oh by the way, in the first chapter there is one mistake, you accidentally put Grandchamp instead of Grandcamp


  5. Ed Darrell says:

    Early focus was on the storage of liquid ammonium compounds, anhydrous ammonia — but the crater is where the ammonium nitrate was stored in big, open bins.


  6. The Texas fertilizer explosion at present echoes that of what happened in 1947. The explosion in the west doesn’t really seem to be caused by ammonium nitrate though.


  7. […] A nasty fire, a small, brave band of volunteer firefighters, a commonly-used but very dangerous agriculture chemical, unfortunate winds, inadequate emergency response equipment, and bad siting, seem to have combined to make yet another cautionary tale from yet another explosion disaster in Texas (remembering the natural gas explosion in New London in 1937 that killed 300, mostly school kids, and the Texas City fertilizer explosions of 1947 that killed 576). […]


  8. James Kessler says:

    And Morgan will blame that on government regulation


  9. […] April 16 marked the 66th anniversary of the massive explosions of fertilizer on ships in the harbor … — 576 people died in that 1947 disaster. […]


  10. Ed Darrell says:

    Most of the stuff I quote is from the union site — as is the photo. What I don’t show as quoted is the little bit I wrote.


  11. j a higginbotham says:

    Ed wrote the main article. The quoted material is taken from, as Ed says, “the IAFF Local 1259 site”. However he presumably got it from a third party, as the quoted picture caption is not from the IAFF site (it misspells “Grandcamp”).

    The fires were caused by improper handling. No one treated the fertilizer as an explosive. Some earlier fires were caused by workers leaving cigarettes on the bags. Spilled material was not properly cleaned up and mixed with organic matter, making it more hazardous. Some of the bags were reported to be warm from the manufacturing process. Which specific cause started the fire which led to the steam heating (rather than water extinguishing) which produced the first explosion is unknown.


  12. Val says:

    oh, I forgot to ask; Ed, are you the one who wrote this article?


  13. Val says:

    I read somewhere (possibly on Wikipedia) that ammonium nitrate can heat up and become explosive in a confined area. It is possible that’s how the fires started. I don’t know if this is true, since they surely would have talked about it in other articles. Most likely people just don’t know.


  14. Ed Darrell says:

    Val, I regret I don’t know what triggered the first fire — nor do I know if anyone does. If that knowledge exists, I’ll bet Bill Minutaglio’s book has it. Why don’t you look for it at your library?


  15. Val says:

    Do you know how the very first fire was started? Is that still a mystery? Were the bags of fertilizer too close to the furnace, or was one of the crew members smoking? What led to the ammonium nitrate catching on fire?


  16. […] “disasters of the last 100 years”).  The list is limited to natural disasters, so the Texas City harbor disaster of 1947 isn’t even considered, and the New London, Texas, school explosion doesn’t make the […]
