NO2 leak


Don't know what is going wrong here, but I'm happy I wasn't around. Does anyone know what is going on here?

That almost has to be a compressed NO or NO2 leak. It looks like winter there and I can't see a leak of ordinary 68% HNO3 making that much gas. Could fuming HNO3 put out that much of a plume?

I would guess that someone put nitric acid in a tank made of a metal that reacts with it. It may have been winter, but the reaction is exothermic and will accelerate.

Perhaps it is not NO2 but Br2. What is the source of this video?

Either way NO2 or Br2, it's awful. Those look like residential buildings in the background. Where was that?



Any other SF Bay chemists?

No idea where that is- I'm not seeing anything distinctive. Could be Germany, could be Russia, could be Alberta (well, the buildings don't really look like Alberta, but...).

I don't know what the source of the video is, I found it on 9gag... usually not the best site to find background information.

More leaking stuff! A couple of days ago in Mainz, Germany. 22 tons of CO2, no injuries because of the gas, only the driver of the truck got some frostbite from the the broken valve. Cool (hihi) photo though.

To me it resembles the mixed nitrogen oxides that are released when HNO3 reacts with metals. Luckily it looked windy there.

I found this article from RT:


Quote:

A tanker truck carrying chemicals burst open in a peaceful neighborhood in Dnepropetrovsk, Ukraine, covering the area with nauseous orange fumes. An estimated two tons of what appears to be nitric acid spilled out and evaporated.

The spectacular leak happened last week in a residential area just meters from a children's playground. A video filmed by a local resident showed the tanker, its driver nowhere to be seen, producing clouds of orange-brown fumes, which were blown towards nearby houses. The smell of the chemical fumes was reportedly felt kilometers away.

A fire brigade arrived on the scene and washed out the chemicals remaining in the tank. Local authorities assured the population the leak did not pose any danger to public health or the environment, but couldn't immediately confirm the extent of the damage. No evacuation was ordered.


There is concern that the chemical transported in the tanker was nitric acid, which can decompose into water, oxygen and nitrite dioxide at high temperatures or exposure to light. Nitrogen dioxide is a toxic gas varying in color from white to dark brown, depending on the temperature.

Could be propellant for a rocket/missile. The Soviets used N2O5+fuel extensively for rocket propellant.

I doubt that N2O5 would be shipped in a tanker like that.

I've seen "children's playgrounds" in Ukraine, particularly in areas like that. Rarely used, a surprising amount of broken glass in the sand, benches that were last in good shape during the Krushchev era.....

That's an awesome picture. I don't understand why the driver was not suffocated.

The driver had the Wind in his favour.

Maybe also the good sense to run upwind as well.

Wow, it looks nasty, but fascinating at the same time... Reminds me of my nitric acid synthesis moments. Hopefully no one was injured from this. Also, the camera man seems to be pretty brave, standing like that, near such quantities of leaking nitrogen dioxide.

Yeah, but clearly, he wanted to get views, otherwise he probably wouldn't risk his life :D

This might have been taken with a dashcam, not that this would give total protection. I understand that the reason we have so many good videos of the Chelbalyinsk meteorite is due to the high popularity of dashcams in Russia.
