What happens when you get into an accident?
Wouldn’t want to be around an H2 leak, some O2 and a flame or a spark.. the pop would be fast and the flammable stuff would burn more spectacularly..like the Hindenburg...at least you can put out secondary fire with water.
*Nine out 10 times, no problem.
**And the tenth time?
*Problem.
“What happens when you get into an accident?”
Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly. Hydrogen is a colorless, odorless, and tasteless gas. Natural gas and propane are also odorless, but a sulfur-containing (Mercaptan) odorant is added to these gases so that a leak can be detected. At present, it is hard to tell if there is a hydrogen leak because it has no odor to it. Hydrogen is a very light gas. There are no known odorants that can be added to hydrogen that are light enough to diffuse at the same rate as hydrogen. In other words, by the time a worker smells an odorant, the hydrogen concentrations might have already exceeded its lower flammability limit.
Hydrogen fires are invisible and if a worker believes that there is a hydrogen leak, it should always be presumed that a flame is present. When workers are required to fight hydrogen-related fires, employers must provide workers with necessary protective gear to protect them from such invisible flames and potential explosion hazards. There are several OSHA standards that may apply to employers who produce or use hydrogen.

Notice the terms unseeable flames and explosions? That’s your answer.
