- Attentiveness to proper procedure would have prevented this incident.
- This incident also underscores is the need for rigorous training on hydrogen properties and behavior, not only for the operators of fueling equipment but also…
- A SOP should be developed which prohibits drivers from backing into the fill position.
- As a precautionary measure to mitigate similar events in the future, piping barriers should be installed which protect critical H2…
- All tank trailers should have a safely accessible auxiliary shut off valve in case of spills.
- Emergency personnel need to have access to all of the appropriate protective clothing, including shoes. Liquid hydrogen is stored at 20…
Standard procedure must be followed in all cases. Assumptions are made at great risk. Risk also increases with complacency.
Refueling operations need to be conducted in a careful and attentive manner, and operators need to be aware of the potential consequences of their actions.
