Fire Drill
The Fire Drill occurs twice a year; one time it is announced in advance to all students, the other time is a "secret" which only the staff know about. However, it always occurs ten minutes into a lesson, and a tell-tale sign is the fact the teacher will ramble on about something irrelevant for far longer than usual to bide time.
Once the fire alarm sounds, students proceed to the Astroturf where registers are taken and people are shouted at through an ineffective megaphone. The previous procedure was that years 7-11 lined up on the courts, in close proximity to the potentially burning building.
It is rare that the fire alarm is set off by a real fire. One occasion involved someone burning down room 7 in 1998 after a rather vigorous thermite reaction. Another occurred when a heater in the Food Technology room starting smoking a bit. Both resulted in 137 fire engines appearing within six minutes, in accordance with government over-reaction policy.
