Several parties were involved in hydrogen quality sampling when it was discovered that a hose which was being used in the collection process, connecting two sampling components, was not rated for the pressure to which it was being subjected. Upon discovery, the process was stopped, the hose was removed, and an alternate configuration of the equipment was implemented before carrying on the sampling.

During a 70-MPa fueling, the fueling hose breakaway separated. The separation occurred without any extraneous forces other than the pressure of the gas internal to the fueling hose. Upon investigation, it was determined the pull force set point was incorrectly adjusted. No further issues or actions.
