Narrative:

My co-worker and I were tasked with adjusting and selling to inspection; a girt bar fitting on the right aft service door of [an A319]. I was standing behind my partner as the safety observer; reading over the [aircraft maintenance manual]. During the same period of time my partner was working on the door checking for the proper tolerance while the emergency slide is armed as the [aircraft maintenance manual] instructs. As I was going over the [aircraft maintenance manual]; I hear an unusual noise and looked up to see the slide has been deployed.
