At 6 pm, the combustion of corn in one of a silo’s 2 dryers activated the “high temperature” detection alarm inside the exhaust air duct, in shutting down the installation. Fire-fighters were alerted 10 min hence, after a hot spot on the dryer’s lower section had been located. The drying column was cooled using extinguishers and the corn was drained under fire-fighter protection by installing a water hose. The grain was stacked within the courtyard. The incident was brought under control by 8:15 pm; first responders left the site 15 min later. The silo operator conducted monitoring rounds until midnight. A worn riveted plate attached to one of the dryer access hatches prevented grain from being discharged, causing the grain to heat in this sector adjacent to the burner zone. The dryer was restarted the following Monday after cleaning and then replacing the heated brackets and clamping plates of the installation’s 6 access hatches. The operator instituted a thorough inspection of all such plates on both dryers upon completion of each grain collection campaign.
