Safety Requirements for Self-Retracting Devices ANSI Z359.14-2014
A new ANSI standard for self retracting devices (SRD’s) is in effect. This new standard
supersedes the requirements for SRD’s (including SRL’s with and without retrieval)
found in ANSI Z359.1 and Z359.4.
The new standard addresses advancements in the design of SRD’s, including those retracting
devices used in sharp leading edge applications where the line may contact a sharp edge,
plus updates in testing criteria, product performance, device classifications and inspections.
Which products are affected by the new Standard?
The standard applies to all types of self retracting devices (SRD’s). This includes the
traditional self retracting lifelines (SRL’s) plus SRL’s with retrieval (SRL-R’s) and SRL’s that are
rated for sharp leading edge applications (SRL-LE’s).
Important Sections in the New Standard
The important sections of the standard which are new or different than the past SRD
information found in ANSI Z359.1 and Z359.4 include the following:
Self Retracting Device Classifications
• Devices are classified according to dynamic performance. Most devices will
be grouped in Class B. The arrest distance is the total vertical distance required
to arrest a fall, including the deceleration distance and the activation distance.
This affects the required clearance for a retractable unit.
• Class A= Maximum arrest distance of 24 inches. Average arresting force not
to exceed 1350 lbs. Not approved for foot level drops or sharp leading edge work.
• Class B= Maximum arrest distance of 54 inches. Average arresting force not
to exceed 900 lbs. Not approved for foot level drops or edge work.
Sharp Leading Edge Class B (SLE)
• For the first time, a sharp leading edge test for SRL’s is included in the standard.
Specific test criteria must be met in order for devices to be labeled for sharp
leading edge work (where the lifeline can come in contact with a sharp edge
during fall arrest).
Approved for
SHARP LEADING EDGE
and foot level drops. 3rd party certified by an ISO 17025
accredited test laboratory. Lengths up to 110’. Meets OSHA & ANSI Z359.14-2014 Class B (SLE).

Information
Note:
All Ultra-Safe Retractables (web and wire) are approved for
below foot level drops
such
as catenary lines and sharp leading edge work up to 78” free fall.
