- 477
- Quality
- Description
- The explosion affected a furnace for the annealing of wire in special reducing atmosphere. An excess of hydrogen resulted from an insufficient purge with [96% N2 and 4% CO].

- Main component involved?
- Reactor / Oven / Furnace / Test Chamber
- How was it involved?
- Internal Explosion (H2-Air Mixture)
- Initiating cause
- Inadequate Or No Purge
- Root causes
- Root CAUSE analysis
- The INITIATING CAUSE was the creation of a flammable atmosphere (probably air-hydrogen).
The ROOT CAUSE was probably due to a shortcoming in the purging procedure.
