A fire broke out in an oven for fireworks stars at the time a technician remotely opened the oven doors to cool the contents. The 30 kg of composition made from barium chlorate, accroides gum, fine coal and sulphur were consumed by the fire, accompanied by projections of ignited stars. The oven control commands were damaged.

Additional tests, conducted subsequent to a similar incident that occurred on 10th March (ARIA 37060), demonstrated that the reintegration of manufacturing rejects into the normal cycle served to drop the spontaneous ignition point of the composition to 75°C, which was a temperature potentially reached during oven heating phase. Rejects would no longer be added back into the production cycle, but instead directly destroyed. Also, the heating control commands were moved away from the oven itself.
