使用する際の注意点

With almost any of the transitive senses except sense 1, the object may appear before or after the particle if the object is a noun or noun phrase:

He blew the room up without blowing up the building.

If the object is a pronoun, then the pronoun must come before the particle:

Try not to blow it up.

(Putting up between the verb and the pronoun, as in "blow up it", converts the particle into a preposition, and thus changes the meaning.)
