Good LGBT Diamond Peace Love CNA Shirt

I used to work in a lab that had some cryogenic equipment (SQUID magnetometer). We used to have "Welding Grade" and Ultra High Purity (UHP) helium. You needed to use the UHP helium to force liquid helium into the magnetometer, otherwise you could get frozen nitrogen in the magnetometer. Never heard of "Balloon Grade" before, that's funny.Balloon grade is the low end of helium purity. Still very pure, but not on the scale of helium used for divers breathing mixes or helium used in MRI machines.

My friend in Beirut says that the Russians dropped off 50 tons of ammonium nitrate at that port in 2014. The government was supposed to clean it up but didn't and just left it there. They don't know how it was ignited though.Naw, Look for maps, I think he’s just behind the last warehouses, just in front of the tall apartment buildings. Otherwise it would have been impossible to get the low, unobstructed view of the white building from that angle. At least we know now that not everyone on the roadway I saw in other videos died...

Instead of asking "why do I expect these companies to do anything other than to try to make more and more money?" I suggest you ask yourself why news outlets are for-profit in the first place.We entirely depend on them just doing the right thing but they don't. They haven't done the right thing for years and years. So we should stop expecting them to do anything for the good of the country. Buy it :  Awesome Even Jesus Had A Fish Story Shirt

Ammonium nitrate is very stable on it's own. There are thousands of these warehouses scattered across the US. They're usually in farming communities and they store many tons in close proximity. While there have been a small number of accidents I would say that, compared to the volume that has been safely stored, it is relatively safe to store it this way.First story I read said ammonium nitrate. Typically used as a fertilizer, however that was also the explosive component of the OKC bombing in the 1990s. That was a quantity that fit inside a box truck, not an entire storage facility like this was. The number of dead will be in the thousands when all said and done most likely.
