1000 lbs of TNT Detonated-Hoopa Evacuated and Hwy 96 Closed

According to the Two Rivers Tribune,

Over 1,000 lbs. of TNT was detonated in downtown Hoopa—a remnant explosive formerly used in logging operations— that was located earlier this morning between the former Jackson’s Trailer Park and Joe’s Deli. According to Mendes the intense heat should consume the product within four to five hours. The team will send a robot to check the stability of the detonated area.

Highway 96 in downtown Hoopa remains closed. Officials are advising residents to stay indoors and out of the downtown Hoopa area. Air quality officials said carbon monoxide emissions and valley inversion make the situation more dangerous, adding anyone with respiratory distress should call the ambulance.  The closure will remain in effect until further notice, however officials are aiming to have the scene cleared by 6am Thursday morning. Hoopa Tribal Police Chief, Bobby Kane,  said anyone trespassing will be asked to leave and will be detained if they do not comply.

  • 1,000 pounds sounds like more than a “remnant”. How does someone forget that they’ve got a half ton of high explosives laying around a populated area going unstable?

  • Wait, so this stuff has been lying around for how long?

  • I heard on the radio last night it was dynamite, which years ago contained nitroglycerin. Nitroglycerin can become very unstable over time. I don’t think TNT does. You can burn either of them for disposal.

    A decade or two ago, some old dynamite was found in some cave up by one of the forest fires near Happy Camp(?). It was the nitro based dynamite and the nitro had settled and crystallized on the outside making it very unstable. The late Dennis Bakke and at least one other National Guardsman removed the dynamite and disposed of it. I recall Bakke getting some medal for his part in the operation.

    Nowadays nitroglycerin isn’t used in dynamite. They use RDX or some other explosive as a base that makes it stable just like regular high explosives.

    • True, except it’s ammonium nitrate mixes that are commonly used now – RDX is the ingredient of C-4 and it’s only used in military compositions….
      Ammonium nitrate mixes can be slurried and pumped like thin gruel – it’s the ingredient in all those massive mining blasts you see on youtube….It’s also available in stick form….
      Detonation = explosion, obviously they meant burning…..I’m surprised they burned it as occasionally it will explode in a hot fire.

      Imagine living and working next to that all those years!

  • I see the Times- Standard says it was TNT, too. Strange. Don’t understand why they thought it was so urgent to dispose of it, if it was indeed TNT. They could have given it to the local National Guard for training purposes, or something along that line.

  • There is a big difference between detonated and incinerated.
