Cable guides that do not require manual manipulation to pass them are preferable. Weather-resistant, synthetic cables that have long lifetimes in corrosive atmospheres are available. They offer the additional advantage of radio-frequency transparency for antennas. Synthetic cables must be protected from wind abrasion, with the structure by suitable clearance spacing.

Both the employer and employee should realize that components of a fall protection system may not be interchangeable. For instance, if a commodity-grade rope is used for a lifeline, the authorizing authority must be certain that is the correct diameter and has the test strength for use with a specific rope-grab device on a prolonged basis.

In the case of a fall or near-miss incident, the fall protection administrator should appoint a competent or qualified person to conduct an incident investigation. The investigation will help determine if the fall protection program has established the appropriate control method for a given hazard, if the training is adequate, and what improvements are needed to ensure such an incident does not reoccur.

More important, articulated boom lifts have the propensity for the bucket to catapult the worker from the bucket on occasion. If the boom is extended while the unit is being moved, a small curb, obstruction, or floor hole cover could cause the arm to exaggerate the movement in the bucket and throw the worker from it. This is why the use of fall arrest system is critical for work in articulated boom equipment.

All horizontal lifeline designs must be approved by a qualified engineer who is a specialist in this field (OSHA 1910.66, Appendix C, and 1920.500, Appendix C). Readers are expected to use the most recent standards. OSHA standards may be checked at www.OSHA.gov and ANSI standards at www.ANSI.org. States with their own plans must update their standards within six months of any change in the federal OSHA standards.

Three Point climbing without fall protection e.g. (movement at height with two hands & one foot alternating with two feet & one hand) can be better analyzed as follows:
