Neumann H2 – Safety Hydrogen?

Facts:

• Hydrogen has a high lower flammability limit and a high flammability temperature (4% and 580 °C, respectively), but is flammable over a wide range. It is easily ignited on ignition.
• There is little chance of ignition in an open space due to the rapid dissipation of hydrogen due to its low density.
• Does not form fuel "puddles".
• Does not float on the surface of the extinguishing agent.
• Hydrogen burns at high temperatures but very quickly. If there is no combustible material nearby, the fire will quickly go out.
• Hydrogen flames are difficult to extinguish and can spread quickly.
• Hydrogen flame emits little heat and is less likely to cause burns.
