Estimated Asset Damage:
Before welding, a contractor noticed a flame coming from a hydrogen pipe that was did not appear to be in use within the aircraft manufacturing plant. Despite several attempts to extinguish the fire, it grew larger and led to a factory shut down and all production stopped. 
Preventability with DetecTape
In industries with a small margin for error like aerospace, having hydrogen lines (regardless of their use) wrapped in DetecTape could have indicated to the welding contractor that a leak existed. This potentially could have prevented the extreme risk of an open flame in the facility and reduced production time lost.
