1. A self-retracting lifeline assembly comprising:
a housing;
a housing cover piece;
a shaft having a proximal end and a distal end, the shaft fixedly coupled at the proximal end to the housing, thereby preventing rotational motion of the shaft relative to the housing;
a spring carried on the shaft;
a drum comprising a pawl mechanism, the drum supported upon the shaft at a position distal the spring, the drum configured to retain a lifeline for selective deployment and retraction, wherein the drum is a two-piece construction with a first drum portion defining a compartment and a second drum portion forming a cover for closing the compartment; and
a brake module carried on the shaft at a position distal the spring and distal the position at which the drum is supported on the shaft, wherein the housing cover piece and the second drum portion are removable to allow for removal of the brake module as a self-contained subassembly, and wherein the brake module can be disposed to and removed from the shaft via the distal end without moving the spring relative to an axial direction of the shaft.
