Anchorage Requirements

All anchorages to which the Personal Shock Absorbers and Shock Absorbing

Lanyards attach must meet the requirements of OSHA 29 CFR 1910.66 and

ANSI Z359.1-2007. OSHA states:

Anchorages to which personal fall arrest equipment is attached shall

be capable of supporting at least 5,000 pounds (22.2 kilonewtons) per

employee attached, or shall be designed, installed, and used as part of a

complete personal fall arrest system which maintains a safety factor of at

least two, under the supervision of a qualiﬁed person.

ANSI Z359.1-2007 states that anchorages in a personal fall arrest system must have

strength capable of sustaining static loads applied in all directions permitted by the

system of at least:

(a) Two times the maximum arrest force permitted on the system with

certiﬁcation, or

(b) 5,000 lb. (22.2 kN) in the absence of certiﬁcation

When more than one personal fall arrest system is attached to the anchorage, the

strength in (a) and (b) must be multiplied by the number of personal fall arrest

systems attached to the anchorage.

Anchorages used in controlled descent and rescue systems must be capable of

supporting loads of 3,100 ft-lb. (13.8 kN) for non-certiﬁed anchorages or a 5:1

safety factor for certiﬁed anchorages per ANSI Z359.4-2007.

Anchorages used in restraint systems must be capable of supporting loads of

1,000 ft-lb. (4.5 kN) for non-certiﬁed anchorages or two times the foreseeable

force for certiﬁed anchorages per ANSI Z359.2-2007.

Anchorages used in work positioning systems must be capable of supporting loads

of 3,000 ft-lb. (13.3 kN) for non-certiﬁed anchorages or two times the foreseeable

force for certiﬁed anchorages per ANSI Z359.2-2007.

Anchorages should be located as vertically as possible above the user’s head and

be positioned as not to exceed the maximum allowable free fall for the system.
