• Do not allow cable, rope or webbing lifelines to come in contact with anything that will damage
the lifeline including but not limited to sharp, abrasive, rough or high temperature surfaces,
welding, heat sources, electrical hazards, or moving machinery.

D-ring of the user’s harness and the snaphook of the Falcon.

B. SYSTEM COMPATIBILITY

Miller approved components. Substitution or
replacement with non-approved components will
endanger the compatibility within the system and
may affect the reliability and safety of the total
system. It is recommended that the user wear a
Miller full-body harness to distribute the fall
arresting forces over the body and to keep an
unconscious or injured worker in an upright
position.
