2.5 ANCHORAGE STRENGTH: The anchorage strength required is dependent on the application type. The

following are the requirements of ANSI 359.1 for these application types:

A. FALL ARREST: Anchorages selected for fall arrest systems shall have a strength capable of sustaining

static loads applied in the directions permitted by the system of at least:

1. 5,000 lbs. (22.2 kN) for non-certified anchorages, or

2. Two times the maximum arresting force for certified anchorages. When more than one fall arrest

system is attached to an anchorage, the strengths set forth in (1) and (2) above shall be multiplied by

the number of systems attached to the anchorage.

B. RESTRAINT: Anchorages selected for restraint and travel restraint systems shall have a strength

capable of sustaining static loads applied in the directions permitted by the system of at least:

1. 1,000 lbs. (4.5 kN) for non-certied anchorages, or

2. Two times the foreseeable force for certied anchorages. When more than one restraint and travel

restraint system is attached to an anchorage, the strengths set forth in (1) and (2) above shall be

multiplied by the number of systems attached to the anchorage.

C. WORKING POSITIONING: Anchorages selected for work positioning systems shall have a strength

capable of sustaining static loads applied in the directions permitted by the system of at least:

1. 3,000 lbs. (13.3 kN) for non-certied anchorages, or

2. Two times the foreseeable force for certied anchorages. When more than one work positioning system is

attached to an anchorage, the strengths set forth in (1) and (2) above shall be multiplied by the number of systems

attached to the anchorage.

D. RESCUE: Anchorages selected for rescue systems shall have a strength capable of sustaining static loads applied

in the directions permitted by the system of at least:

1. 3,000 lbs. (13.3 kN) for non-certified anchorages, or

2. Five times the foreseeable force for certified anchorages. When more than one rescue system is attached to an

anchorage, the strengths set forth in (1) and (2) above shall be multiplied by the number of systems attached to

the anchorage.

E. CLIMBING: The structure to which a climbing system is attached must sustain the loads required by that

particular system. See instructions for climbing system for requirements.
