Disasters in The Library

Okay guys. Real talk here.
Hogwarts Castle is insanely dangerous.

For some of you, this isn't news at all. Disasters at the school are a regular occurrence. Just a light perusal of Hogwarts: A History reveals that Hogwarts has had a total of more than twelve major disasters, not including the Battle of Hogwarts. That's why it's necessary for our library to have disaster plan in place to save our precious collection.

Let's have a rundown of said Disaster Plan implemented by the venerable Madam Pince, shall we?

----------
1. Evacuate all Staff and Students from the Library. 
 
Speaks for itself, right? Gather all the students and get them out of the room in a calm and orderly fashion.

2. Rapid Assessment of the Emergency.

Look into the danger and the damage extent.

3. Take Steps to prevent any further damage to the collection.

Remove as many endangered materials as possible from the Danger Zone.

4. Notify the Department of Magical Accidents and Catastrophes.

You could send an owl (the slowest method), call via Floo Powder, or send a teacher to Apparate there (the fastest method).

5. Stabilize the environment.

Close the library and do not let any unauthorized people inside.

6. Do comprehensive assessment of collection damage.

Take inventory and take note of the extent of the damage done to the collection.

7. Salvage damaged items and begin repairs.

Only do this after the Library is guaranteed safe.

It's a straightforward plan. Thankfully, we haven't had to implement this plan very often, but there is one recent incident that comes to mind.

One afternoon, Cadmus Finnigan was tending to his schoolwork within the library. As far as I know, he was studying his Standard Book of Spells when he decided he would try a spell out for himself. Unfortunately, he was not aware that, or perhaps ignored our clearly-stated policy- Spells aren't to be practiced outside of the classroom for underage wizards - particularly first years! It turned out he really did take after his father Seamus Finnigan (a boy who could set water on fire, given half the opportunity)- as his spell went badly wrong and his entire stack of textbooks burst into flames!

As a result, students began to use Aguamenti to distinguish the fire. While this might have diminished the threat of fire to our collection, the amount of water spewing out of student's wands quickly turned into a minor flood. Next thing we knew, half of our History of Magic books were soaked through and bloated, almost beyond repair. Fortunately, we were able to reverse the effects of the spell and revive the books.

So you can see why having a disaster plan in place is so important in a place like the Hogwarts Library - especially with that Finnigan around.
