Description of Driving Event:
Flammable and toxic vapors can be expelled into the deservicing hangar at DFRC, providing a potential for fire, explosion and toxicity above the permissible exposure limits (PEL). No venting is planned, however, pressure bleed vents do exist on these systems and are expected to boil off and vent periodically in short bursts if the fuel cells have been secured.
