All available EVMs in a district are normally stored in a treasury or a warehouse under the direct control of the District Electoral Officer (DEO). Exceptions can be made in case of unavailability of storage space, but the designated treasury or warehouse should not be below the level of tehsil. The warehouse is secured by a double lock, guarded round the clock by policemen or security guards, and is also under CCTV surveillance. During a non-election period, EVMs cannot be moved out of the warehouse without specific instructions from the Election Commission. The first-level check of the EVMs by engineers is done here, in the presence of representatives of political parties.

 

During poll season

 

Closer to the election date, EVMs are allocated randomly to various Assembly segments (in a Lok Sabha seat) through a software in the presence of party representatives. If the representatives are absent, then a list of allocated EVMs and VVPAT machines for each Assembly segment is shared with the party office. From this point, the Returning Officer (RO) of the Assembly segment takes charge of the allocated machines and stores them in designated strong rooms.
