Hydrogen Gas Safety

Hydrogen is used to produce many products (glass, peanut butter, soap, toothpaste) and as fuel for space exploration and eco-friendly vehicles. As with any gas, safe handling practices must be followed.

Diffusion

• Provide plenty of room and adequate ventilation around contained hydrogen in case of leakage. Hydrogen dilutes quickly when not contained. It is the lightest element in the world and rises twice as fast as helium, states the U.S. Department of Energy.

Flammability

• Do not mix hydrogen in a container with oxygen or other oxidizers. Hydrogen cannot combust unless combined with an ignition source and an oxidizer. Once ignited, it burns more quickly, with more control and at a lower heat than gasoline, states the National Hydrogen Association. Water vapor is emitted when hydrogen burns.

Manufacturing

• Use federally-approved hydrogen products. Because the presence of the odorless, colorless gas is not detectable by human senses, manufacturers of hydrogen products must provide leak sensors and adhere to strict safety guidelines and testing.

Fueling

• Fuel-cell vehicles use electric motors powered by a mixture of hydrogen and oxygen, describes the California Fuel Cell Partnership. Owners of hydrogen-powered vehicles must not smoke or use cell phones while fueling their vehicles. Hydrogen pumps attach securely to the fueling tank to avoid leakage.

Characteristics

• Hydrogen is as dangerous as any other flammable fuel--such as gasoline, states NHA. In contrast, it is nontoxic and does not emit any harmful greenhouse gases.
