- Description
The incident occurred when delivering liquid hydrogen to a stationary storage system of a semiconductor plant. Cold gaseous hydrogen was vented for unknown reason, ignited and created a plume of flames several metres high. The fire receded within seconds, leaving the truck with little damage and its driver unharmed.
The first notification of the ignition was given by the plant personnel. The driver sealed off the vent within seconds and stopped the leak.- Event Initiating system

- Initiating cause
- unknown
- Root CAUSE analysis
The INITIATING and the ROOT CAUSES are of difficult identification, because the cause of the leak is not reported, and the source for the ignition remained unknown.
It can be assumed that a material failure at one of the trailer-to-stationary storage connections was at the origin of the leak.- Root causes

Lesson Learnt
- Lesson Learnt
The safety equipment in place and the timely action of the truck driver prevented the fire from spreading into the tanks.
The lack of details on the specific location of the leak and the specific actions taken by the driver to isolate the leak do not allow for a more in-depth analysis.
