ASTM might be the best point of contact for crafting this test. The ASTM F38 Committee on Unmanned Aircraft Systems is probably the best source of information on drone airworthiness criteria. They have a subcommittee developing a standard on fuel cell drone safety. One Panel member has been involved in a test with an LD vehicle tank filled with hydrogen that was dropped 60m onto a concrete pad…
LNG storage, plumbing, and other systems can’t be directly retrofitted to handle hydrogen. The LNG components and systems will need to be removed and replaced with equipment specifically designed for hydrogen. If the concept is to convert existing equipment or an existing ship, then it’s probably impossible. If it’s to convert an existing LNG design on paper, then it’s probably impractical.…
Type 1 steel tanks can be cut with a welding torch, so they can definitely be impacted by flame impingement. Above 400-500 C° the material properties of steel will start to degrade.
It is challenging to protect a vessel, either Type 1 steel or composite Type 2, 3, or 4 from an impinging fire since the safety devices may not see the elevated temperatures in the area of impingement.…
It is common to have combustible materials and fuels in a building during construction activities. Commissioning is typically considered part of construction. It is good to see that fire suppression is available. However, given the lack of alarm capabilities, it would seem prudent to have a fire watch posted when hazardous materials are present or being used. Regarding requirements, the…
In addition to ANSI/CSA FC1-2014, search for fuel cells in the Hydrogen Fuel Cell Codes & Standards
or H2Tools Bibliography sections.
Example safety guidelines are listed below but may not be all-inclusive (e.g., they do not cover general practices such as lockout/tagout, management of change, job safety analysis), and most are the same as for gaseous hydrogen. Also reference NFPA 2 and CGA documents such as H-3, H-5, and H-7. Additional safety training material can also be found on the following link to courses and…
