DESCRIPTION:On July 29\, 1956\, 19 firefighters were killed while battling
  a fire at the Shamrock Oil Refinery in northern Texas. This incident caus
 ed the fourth largest loss of firefighter lives in U.S. history.\nWe remem
 ber those killed 54 year ago tomorrow: Allen W. Cleveland\, Billy Joe Dunn
 \, Sam A. Gibson\, Jr.\, Albert O. Milligan\, Paschal Pool\, Meryl W. Slag
 le\, Donald W. Thompson\, Ray Biles\, Lewis A. Broxson\, Gilford R. Corse\
 , Claude Emmett\, Alvin Freeman\, D.C. Lilley\, James L. Rivers\, Virgil W
 . Thomas\, Gayle Weird\, Rupert Weir\, Charles Lummus and Joe West. All we
 re firefighters who worked for either the Sunray or Dumas volunteer fire d
 epartments or the Shamrock Industrial Fire Brigade.\nFlammable hexane and 
 pentane vapors began escaping from the spheroid designated as No. 199 at t
 he Shamrock Oil and Gas Refinery. A relief valve released\, turning pentan
 e loose to the ground. The wind was blowing toward the process area\, spec
 ifically an asphalt tank about 350 feet away under which a small fire was 
 kept. This photo shows tank 199 before the BLEVE.\nAt 6:53 a.m.\, the 12\,
 000-barrel\, pumpkin-shaped spheroid tank containing about 500\,000 gallon
 s of pentane and hexane gases exploded\, sending a mushrooming fireball in
 to the air and burning fuel to rain down for more than a mile.\nOn the mor
 ning of July 29\, 1956\, flammable hexane and pentane vapors began escapin
 g from the spheroid designated as No. 199 at the Shamrock Oil and Gas Refi
 nery\, a petroleum tank farm located between the small towns of Sunray and
  Dumas\, Texas. According to an article in Industrial Fire World\, a relie
 f valve released\, turning pentane loose to the ground. The wind was blowi
 ng toward the process area\, specifically an asphalt tank about 350 feet a
 way under which a small fire was kept. At about 5:45 a.m.\, vapors ignited
 \, then flashed back to No. 199.\nAccording to the NFPA\, for the next hou
 r\, firefighters and plant workers were occupied with both a ground fire i
 nvolving a liquid spill from a possible line leak in the vicinity of the t
 ank’s pump inside the dike\, and a fire at the gauging device and vents.
  Eventually\, flames from the dike fire rose 40 feet high\, enveloping the
  spheroid.\nAt 6:53 a.m.\, the 12\,000-barrel\, pumpkin-shaped spheroid ta
 nk containing about 500\,000 gallons of pentane and hexane gases exploded\
 , sending a mushrooming fireball into the air and burning fuel to rain dow
 n for more than a mile. The fireball ignited a 20\,000-barrel diesel oil t
 ank that contained 6\,500 gallons\, as well as two tanks of crude oil\; on
 e contained 6\,000 to 8\,000 barrels and the other contained 2\,000 barrel
 s. These tanks were 450 to 550 feet from spheroid No. 199. An 80\,000-barr
 el with a floating roof containing gasoline located about 225 feet away ha
 d two seal fires that were extinguished. A sixth tank smoldered but was al
 so extinguished. \nAccording to GenDisasters\, 15 firefighters burned to d
 eath almost instantly when the hot wall of fire shot across the ground. Th
 e other four died later of complications from their burns. Forty others\, 
 exposed to the explosion from a great distance\, were severely burned.\nTh
 e fire burned for days.\n
