Fire drill

A fire drill was a method of practising the evacuation of a building for a fire or other emergency. Generally, the emergency system (usually an alarm) was activated and the building was evacuated as though a real fire had occurred. When Commander Kess raised an alarm at Ood Operations because of irregular activity amongst the Ood slaves, Solana Mercurio lied to buyers interested in the Ood, telling them it was just a mere fire drill.
