+## The capacity basis is the single most important decision in anchorage design and shall be selected and stated explicitly for each anchor.
### The prescriptive basis rates each anchor at 5,000 lb (22.2 kN) per attached worker for personal fall arrest, per OSHA 29 CFR 1926.502(d)(15) and 29 CFR 1910.140; this is the default for single-user roof maintenance anchors. {note}

## A travel-restraint-only anchor rated below the arrest capacity shall be permanently marked "RESTRAINT ONLY" so it cannot be mistaken for an arrest anchor.
−### A restraint anchor that is clipped into beyond its restraint radius becomes an arrest anchor and can fail; marking and layout shall prevent this misuse. {note}

### A davit base socket is a permanent sleeve cast into a concrete parapet or welded to structural steel that receives a portable davit mast for window-cleaning or BMU operations. {note}
−### Davit socket and tie-back locations must be coordinated jointly by the structural engineer and the facade or BMU access consultant, because a misplaced socket cannot be relocated after construction. {note}
