If the school is to experience a Bomb threat, the school principal will make a detailed announcement or a message will be delivered to that teacher! Then usually the school will be evacuated imedantly, to that classroom's detailed location!
The school is required to make seasonal fire drills due to the state and local fire departments. Usually they are made in the fall/ winter term. Then usually the principal will make a un-anounced fire drill at the end of the school year! When a fire evacuation is im force the school will usually hear the fire alarm go off, but if it is a false alarm the office will make an announcement following the alarm!
The school usually makes these drills/safety plans around the spring of the year! If Inclement weather occurs the principal will make an announcemet on the intercom: "Please move your students into the hallway immedantly, we are under a bad weather warning for our area!" Then usually the students will sit with there backs against the wall, and then they will place thier head in-between thier legs with legs crossed. they will stay in this position until a: "ALL-CLEAR" is accounced or stated by the school official!*
*Note that the teachers may be required to sit in the position as students if the warning is ahead straight towards the school!!!!
