fall restraint vs fall arrest anchor point requirements

Anchor point requirements for fall restraint and fall arrest systems are dictated by regulations like OSHA and standards such as ANSI. These standards ensure the anchor can withstand the forces generated during a fall or restraint event.

For fall restraint systems, the anchor point must be capable of supporting a static load. For instance, a temporary anchor point should have an ultimate load capacity of at least 3.5 kilonewtons (800 pounds-force) per worker attached in any direction in which the load may be applied. Some regulations specify a safety factor, such as four times the intended load. [3] [2]

In fall arrest systems, anchor points must meet more stringent requirements. A common requirement is that anchor points have an ultimate load capacity of at least 22.2 kilonewtons (5000 pounds-force) per worker attached in any direction in which the load may be applied. Some regulations allow for engineered anchorage with a capacity of two times the maximum arresting force anticipated. [3] [5]

Here are key considerations for anchor points in both systems:

• Strength and Stability: Anchors must be appropriate in terms of strength, stability, and location for the work being done.
• Regular Inspections: Inspect anchors visually for damage, corrosion, and suitability before each use. Permanent anchors should be inspected by a competent person at least once a year, and records of these inspections should be maintained.
• Professional Certification: Permanent anchor points and anchors with multiple attachment points should conform to the manufacturer's specifications or be certified by a professional engineer.
• Swing-Fall Considerations: When selecting an anchor location, consider the potential swing-fall distance and free-fall distance to minimize the risk of striking objects during a fall.
• Marking: Ensure permanent anchor points used in travel restraint are permanently marked as being for travel restraint only.
