Imagine the police (or army or whoever's job is that) found out that some maniac placed a lot of primary explosives under a building. They have evacuated the building and deactivated the trigger.
What now? You have a barrel full of Acetone peroxide (terrorist's favourite explosive). You move it - it might blow.
Even if it doesn't - can you react acetone peroxide slowly, to avoid explosion?
What do factories do with this compound formed as a side waste?
Could you answer the same for nitroglycerine?
