Sandbox

The Sandbox is a S.H.I.E.L.D. installation at a classified location somewhere in Africa.

History
The Sandbox is where S.H.I.E.L.D. sends items of a potentially bio-hazardous or infectious nature for study and disposal.

It is presumable that agent Felix Blake is a S.H.I.E.L.D. agent here. Agent Phil Coulson and his team brought a Chitauri Helmet that held an alien infection to The Sandbox and handed it over to agent Blake.

Donnie Gill was sent here after the death of Seth Dormer, when they created a super storm testing their Atmospheric Moisture Freezing Device.

After Ian Quinn was captured by Coulson's Team, they were ordered to take him to the Sandbox for interrogation. However, after their adventure in the Guest House, Garrett's Team took Quinn to the Fridge.
