Safety HazardsSafety Hazards

.. Hydrogen has the widest

explosive/ignition mix range with air of all the gases except acetylene. That means that whatever the mix proportion between air and hydrogen, a hydrogen leak will lead to an explosion, not a mere flame.

Laws and RegulationsLaws and Regulations

Flame detectors must be used -Implementation of higher standards to detect

early leaks -“Standard for the installation of stationary fuel

cell power systems” (Wiki) - Codes and standards have been a major barrier to

deploying hydrogen technologies and developing a hydrogen economy

-DOE is currently in the process of devising safety codes, standards and regulations
