Designing with H2
- Hydrogen does not pool on the ground like gasoline
or LPG therefore lowering the explosive potential.
- Hydrogen has a higher flammable and explosive
fuel/air mixture limit than gasoline.
- Hydrogen is flammable and explosive in any confined
space, therefore constant monitoring for gas
build up is necessary. Additionally, a ventilation
system is required to prevent gas build up in the
- Flammable limit:
4% fuel/air mix.
- Explosive limit:
13% fuel/air mix
- Flammable/Explosive limit:
1% fuel/air mix
