Abstract

An obscuration cloud generation device (100) comprises a housing (101) having a door (102) and a frame (103) sized and shaped to accommodate an obscuration cloud generating canister (110) when the door (102) is in a closed state. Activation of the canister (110) emits a composition for forming the cloud. The door (102) has an operably open state in which the door (102) is open at least a predefined minimum extent for exiting of the emitted composition. A door checking system (104) applies a force for opening the door (102) and generates an indication of whether the door (102) is open at least to the minimum extent. A controller (105) is adapted to instruct the checking system (104) to apply the force and to receive the indication to determine, before activating the canister (110), that the door (102) is not blocked from reaching the operably open state.
