General Maintenance Action
Aircraft
We went out to the aircraft and found the slide of the L1 door resting on the entry stand. We tried to push the slide back; but there was no way to re-secure the slide and we could not pin the slide. For safety purposes we were told to pull the stand away from the airplane and the slide then fully deployed.
I assigned Technician Y and Z to the aircraft which was parked in hangar to continue the cabin odor Job card. I was notified that the L1 door slide was laying on the platform on the stand.  Myself and others went to the aircraft to inspect the L1 Door. After further investigation there was no way to re-secure the slide or pin the slide. For safety purposes [it was decided] to move the Stand to prevent any injuries or further damage to the aircraft.
Maintenance crew reported aircraft escape slide detached from entry door.
