A plumber must work at an elevated edge where guardrails are not feasible and uses a personal fall arrest system. What are the essential components of that system?

Under Cal/OSHA fall-protection rules, a personal fall arrest system consists of a full-body harness (body belts are prohibited for fall arrest), a connecting device such as a shock-absorbing lanyard or self-retracting lifeline, and an anchorage capable of supporting the required arresting forces. The system must limit arrest forces and free-fall distance and be inspected before use. Missing or mismatched components can make a fall fatal.
