Mike Steinkopf is on shift at ATV-CC this evening monitoring ATV hatch opening and ingress by the crew. He's just sent in the update below:
Scrubbing has finished, and the final ingress activities have started allowing crew to set-up ATV for crew use during the entire attached phase. Crew will remove the scrubbing equipment and will set up the air exchange duct, which will allow inter-module ventilation, install safety equipment (such as gas masks and a fire extinguisher) inside ATV as well as hand-rails to allow them to work within ATV. After launch and docking, final ingress is the third important mission step.
