Extraction commences with you shooting a flare to the sky.

The Division Extraction Ping

Extraction is a mechanic in Tom Clancy's The Division.

When you find a Loot in a Dark Zone, you need to extract it for decontamination before being able to use it.

Launch a flare using a Flare Gun. Once you shoot the flare, a 90 seconds countdown timer will begin, then an helicopter will come and take your loots and the ones of your Teammates if any.

Note that shooting the flare will alert other players of your presence, who will try to prevent you from extracting your loots by killing you, and extract them for themselves.

Loots can also be taken out of the DZ just by walking out wearing them. You can wear six loots maximum.
