Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704 's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ordinary air.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Hydrogen produced was stored on site, and dispensed as fuel. These projects were first of its kind in California, and proved to be highly successful. The projects clearly demonstrated the safety of hydrogen for general public use. The Hindenburg curse that caused experts to vilify hydrogen [neutrality is disputed] was lifted. Success of these ...
The Task Force is responsible for planning a safe, economical and environmentally sound hydrogen infrastructure, increasing the use of fuel cells in government, increasing the use of hydrogen in distributed power generation, establishing uniform hydrogen codes, standards and safety protocols, and defining vehicle hydrogen fuel system integrity ...
Emissions from burning hydrogen can be negligible but emissions from producing hydrogen are currently higher than direct combustion of the source. [37] Hydrogen has a wide flammability range (3–70% H 2 in air) in comparison with other fuels. [35] As a result, it can be combusted in an internal combustion engine over a wide range of fuel-air ...

Toby Fischer lives in South Dakota, where just 27 doctors are certified to prescribe buprenorphine -- a medication that blunts the symptoms of withdrawal from heroin and opioid painkillers. A Huffington Post analysis of government data found nearly half of all counties in America don't have such a certified physician. So every month, Fischer and his mother drive to Colorado to pick up their ...
