General Maintenance Action
Human Factors
Arrived at aircraft and Planned DG (Dangerous Goods) Summary had printed with the [Maintenance Release]. I separated the FDGS (Final Dangerous Goods) from the [Maintenance Release] noting mentally that it said 'aircraft batteries' and placed it on the console while I reviewed the [Maintenance Release]. Unfortunately I subsequently got distracted by other preflight duties and personnel interactions and forgot about the PDGS (Preliminary Dangerous Goods) which got covered up with all the other numerous documents that are printed during preflight until reviewing my own personal departure checklist while pushing back and realized that we had pushed without having received a Final DG Summary. At that time I asked the First Officer to send a message to Load Planning requesting the FDGS which we received before taxiing.This was all likely due to the fact that we had an extremely light load and the agent approached the cockpit several minutes before scheduled departure time saying that everyone was on board and they were ready if we were ready. About the same time the push crew called on the flight intercom saying they were ready to push. I somewhat hastily called for the Before Pushback Checklist and unfortunately failed to consult my own personal checklist that I normally refer to in order to ensure that I have all documents for pushback; resulting in our pushing before having received the FDGS which had most likely not come yet simply due to the fact that we were several minutes before departure time.
