Narrative:

While accomplishing door-1L (left) and door-1R (right) slide rii inspections; door-1L slide was deployed. We completed door-1L installation up to the bustle installation. We were still having emergency test issues; so the mechanics started the installation of door-1R. We had problems with the door-1R arming; so we were comparing the feel of the arming handle on both 1-Right and 1-Left. We resolved the issues with door-1R and when the mechanic was installing the bustle on door 1-Left I heard the slide deploy. It was the end of shift and we were trying to complete the installation. We were under the assumption the slide was not the emergency light problem; so we wanted to complete the installation of the slides.
