Was hydrogen gas the cause for the Hindenburg disaster?
Almost 80 years of research and scientific tests support the same conclusion reached by the original German and American accident investigations in 1937: It seems clear that the Hindenburg disaster was caused by an electrostatic discharge (i.e., a spark) that ignited leaking hydrogen.
Is hydrogen flammable Hindenburg?
The airship was designed to be filled with helium gas but because of U.S. export restriction on helium, it was filled with hydrogen. Hydrogen is extremely flammable, and the official cause of the fire was due to a “discharge of atmospheric electricity” near a gas leak on the ship’s surface, according to History.com.
How was hydrogen stored in the Hindenburg?
One involved a set of inner hydrogen gas cells to be installed at center of 14 of the ship’s 16 helium cells. The flammable hydrogen would be protected inside the larger cell containing inert helium, and when it was necessary to valve lifting gas, hydrogen, rather than helium, could be released.
Why did the handlers of the Hindenburg use hydrogen instead of helium?
U.S. law prevented the Hindenburg from using helium instead of hydrogen, which is flammable. After the crash of the hydrogen-filled R101, in which most of the crew died in the subsequent fire rather than the impact itself, Hindenburg designer Hugo Eckener sought to use helium, a non-flammable lifting gas.
How did the Hindenburg explode chemistry?
The actual cause of the explosion is still unknown, but the entire volume of hydrogen gas used to float the airship, about 200,000 m3, burned in less than one minute. Thirty-six people, including one on the ground, were killed. Hydrogen is the lightest known gas.
Why do you think hydrogen so flammable?
Hydrogen gas (H2) is composed of two hydrogen atoms stuck together, each containing just one proton and one electron. This simple chemical structure is what makes hydrogen gas flammable and relatively easy to ignite. This is also why hydrogen gas is non-toxic, odorless, tasteless, and light.
What other gas would have been a better choice for inflating the Hindenburg?
LZ-129 Hindenburg was designed to operate with helium and could have conducted transatlantic operations to North America, although with a much smaller payload, with helium as a lifting gas, and the U.S. Navy’s rigid airships were also able to fulfill their missions inflated with helium; U.S.S.
Was the Hindenburg hydrogen powered?
Because of U.S. export restrictions on helium, the Hindenburg was filled with highly flammable hydrogen as a substitute. An apparent spark near a gas leak caused the hydrogen to catch fire, creating a catastrophic spectacle.
Why do you think hydrogen so flammable *?
Some of the reasons that make hydrogen gas very flammable are as follows: Hydrogen is volatile by nature and without any other external effects. They can react very quickly with other near elements and be oxidized. This oxidized form is the cause of the burning of hydrogen.
How do you extinguish a hydrogen fire?
The only sure way of handling a hydrogen fire is to let it burn under control until the hydrogen flow can be stopped. Close the block or isolation valves close to the hydrogen container by remote operation from a safe distance. Use water sprays to extinguish any secondary fire and keep the fire from spreading.
What color is hydrogen flame?
pale blue flame
Roscoe distinctly states that “Hydrogen is inflammable, and burns with a pale blue flame.”
Why was the Hindenburg so flammable?
Hugo Eckener argued that the fire was started by an electric spark which was caused by a buildup of static electricity on the airship. The spark ignited hydrogen on the outer skin.
Can water put out a hydrogen fire?
You can’t burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.
Is hydrogen flammable in a vacuum?
Hydrogen has a very broad flammability range—a 4 percent to 74 percent concentration in air and 4 percent to 94 percent in oxygen; therefore, keeping air or oxygen from mixing with hydrogen inside confined spaces is very important.
How do you check for hydrogen leakage?
Hydrogen leaking from a system should be detectable by one or more of the human senses (sight, smell, hearing, taste, and touch). A typical electronic detection system is comprised of a sensor, transducer, and a device such as a bell, buzzer or light.
What happened to the hydrogen in the Hindenburg?
In lab experiments, using the Hindenburg’s outer covering and a static ignition, hydrogen was able to be ignited but with the covering of the LZ 127 Graf Zeppelin, nothing happened. These findings were not well-publicized and were covered up, perhaps to avoid embarrassment of such an engineering flaw in the face of the Third Reich.
Where can I find media related to the Hindenburg disaster?

Why did they not use helium in the Hindenburg?
U.S. law prevented the Hindenburg from using helium instead of hydrogen, which is more flammable. After the crash of the hydrogen-filled R101, in which most of the crew died in the subsequent fire rather than the impact itself, Hindenburg designer Hugo Eckener sought to use helium, a less flammable lifting gas.
Where is the site of the Hindenburg?
The actual site of the Hindenburg crash is at Naval Air Station Lakehurst, renamed by the Naval Air Systems Command (NAVAIR) as Naval Air Engineering Station (NAES) Lakehurst (or “Navy Lakehurst” for short).
