Human Factors; Procedure
I was the Lead working this outbound and I misloaded the dangerous goods onto the aircraft. We had about 10 pieces of dangerous goods in bags weighing roughly 600 pounds; so I assigned the cargo to Pit 5 on my scanner. There was a breakdown of miscommunication between the back pit loader and myself; and the cargo was loaded into Pit 4 instead of Pit 5 along with approximately 50 bags. The cargo quick packs were scanned into Pit 4 mistakenly; but were assigned to Pit 5 on the [load plan]. I was unaware that we are not allowed to load dangerous goods onto a nesting system and I'm not sure if this is a new SOP but it was new to me. Dangerous goods was surrounded with 15 bags per SOP.
Air carrier Ramp Lead reported a communications breakdown with ramp loading personnel regarding loading Dangerous Goods in correct cargo pit.
