What are the requirements for anchorage in fall protection systems?

The requirement that the anchorage in fall protection systems must be strong enough to prevent full extension of the system, with a safety factor, is crucial for ensuring safety during work at heights. The anchorage serves as the critical point to which a fall protection system is secured, and its strength directly affects the system's ability to stop a fall effectively.

A safety factor is necessary because it accounts for unexpected forces or dynamic shifts that may occur during a fall, exceeding the expected loads on the system. This robustness ensures that the anchorage can withstand the maximum possible load during a fall event without compromising the safety of the worker. It is a fundamental principle of engineering safety design that helps to prevent catastrophic failures in real-world applications.

In the context of the other options, while flexibility and adjustability may be desirable features in certain systems, they are not primary requirements for anchorage. The ability to allow full extension or to be easily removable in an emergency may pertain to certain operational aspects but does not address the essential need for strength and safety in anchorage requirements.
