Mailsafe units are high specification blast containers for the safe indoor containment of small improvised explosive and incendiary devices and letter bombs and for the safe transportation of suspicious mail and bags. Should the device detonate in the Mailsafe, damage to personnel and property in the vicinity of the unit will be significantly reduced or eliminated.

Unlike traditional Bomb Container Bins that direct the force of a blast upwards, Mailsafe will internally contain the explosive pressure. Units can be top or front/side opening and are constructed to allow the penetration of X-rays should a bomb squad investigation team need to be called.
