Final answer:
The correct option is 4. The two basic types of fall protection are fall arrest, which stops a worker after a fall, and fall restraint, which prevents the fall from occurring by restricting movement.
Step-by-step explanation:
The correct answer to what are the two basic types of fall protection is option 4) Fall arrest and fall restraint. Fall protection is a critical aspect of workplace safety, especially in environments where workers are at risk of falling from heights. Fall arrest systems are designed to stop a worker after a fall has occurred and typically consist of a full-body harness, lanyard, and anchor point.
Fall restraint systems, on the other hand, prevent a fall from happening in the first place by restricting the worker's movement to areas where they cannot reach a fall hazard. Both fall arrest and fall restraint play vital roles in protecting workers from fall-related injuries or fatalities.
