RISK ASSESSMENT OF HYDROGEN STORAGE 

Hazard: Exposure to hydrogen will cause asphyxiation
Risk level: Tolerable risk region.
Risk reduction: Hydrogen should be stored in a purpose built compound, which should be well ventilated, and cylinder / tank condition should be periodically checked.


Hazard: Use of high-pressure gas cylinders / tanks.
Risk: Tolerable risk region.
Risk Reduction: Suitable pressure regulating devices used at all times.


Hazard: Hydrogen can form an explosive mixture with air.
Risk: Tolerable risk region.
Risk reduction: Store hydrogen in a well-ventilated location free from fire risk and away from sources of heat and ignition. Smoking should be prohibited.


Hazard: The occurrence of hydrogen flashback and fire following flashback.
Risk level: Tolerable risk region.
Risk reduction: A flashback arrestor, which will automatically shut off the gas flow must be incorporated. 


Hazard: The use of a conventional gas burner to supply hydrogen.
Risk level: Tolerable risk region.
Risk reduction: Modifications are needed, primarily to the nozzle, the length of the burner pipes must be decreased and also the diameter of the burner pipe, at the level of the gas jets.
