MILWAUKEE (CBS 58) -- Law enforcement departments got the chance to train for emergencies at Fiserv Forum.

Milwaukee Police, fire, and other departments took part in the drill. The departments say practice is important to their success.

"It allows us the opportunity to communicate and coordinate all of the moving parts that will be necessary for an sort of emergency in this sort of building to be able to do this in the building again, it is so critical to our success," said Deputy Chief Aaron Lipski with the Milwaukee Fire Department. 

Fiserv Forum is slated for its grand opening Sunday August 26.
