Abstract
A door hasp lock includes a first lock plate having a first flange and a first shield. A second lock plate is detachably engaged with the first lock plate and has a second flange detachably engaged with the first flange. The second lock plate has a third flange. The first lock plate and the second lock plate are engaged and disengaged when disposed at an operating locked state and a non-operating unlocked state, respectively. The third flange is spaced apart from the first flange and the second flange while the door hasp lock is disposed at both the operating locked state as well as the non-operating unlocked state. The third flange may be attached to either the first lock plate or second lock plate and has at least one feature that permits the third flange to break away from the second lock plate when tampered by an unauthorized user.
