and a third protruding member disposed on the first side, the front side, and the second side of the housing, the third protruding member extending across at least a portion of front edges of the housing and having a shorter length than the second protruding member; and a fourth protruding member disposed on the first side, a top side, and the second side of the housing, wherein the fourth protruding member extends across at least a portion of top edges of the housing, and wherein the fourth protruding member includes an opening on the top side of the housing. ### Claim 9 (depends on 1) The housing of claim 1, wherein the outer perimeter of the label area includes a first perimeter section having an arc shape, second and third perimeter sections angled toward each other, and third and fourth perimeter sections substantially parallel to each other. ### Claim 10 (depends on 1) The housing of claim 1, further comprising: a first body part; and a second body part attached to the first body part, wherein at least one of the number of protruding members includes a first portion integrally formed with the first body part and a second portion integrally formed with the second body part. ### Claim 11 (depends on 10) The housing of claim 10, wherein at least one of the number of protruding members is attached to at least one of the first body part and the second body part. ### Claim 12 (depends on 1) The housing of claim 1, wherein a shape of an interior side of the retractable handle corresponds to a shape of the back side of the housing. ### Claim 13 A self-retracting lifeline comprises: a housing including: an outer area disposed on a portion of a first side of the housing, the outer area being planar; a label area stepped down from the outer area, an outer perimeter of the label area corresponding to an inner perimeter of the outer area; a number of protruding members disposed at least on a portion of the first side or an opposite second side of the housing and being stepped up from the outer area; a retractable handle having a first end attached to a top side of the housing and a second end unattached to the housing, the retractable handle movable between a retracted position in which the second end is closer to a back side of the housing and a non-retracted position in which the second end is further from the back side of the housing, wherein the retractable handle is biased to the retracted position;
