<p>Earth Covered Magazine (ECM) structures are built to store AE. They are not designed to resist the damaging effects from an internal explosion, although they can effectively contain the effects from an explosion of very small AE quantities. ECMs are designed to protect their contents and prevent propagation of an explosion that may occur in an adjacent magazine. Proper siting of an ECM, from other Potential Explosion Sites (PES) and Exposed Sites (ES) including operations buildings, piers, aboveground magazines, rail sidings, classification yards, etc., ensures against unacceptable damage and injuries in the event of an accidental explosion.</p>
