ANSI Z359.14-2021
Safety Requirements for Self-Retracting Devices for Personal Fall Arrest and Rescue Systems
TABLE 2 - ANSI STANDARDS
Safewaze SRLs conform to the national standard(s) identified on their ID label. Refer to local, state, and federal (OSHA) requirements for additional information
concerning the governing of occupational safety regarding Personal Fall Arrest Systems (PFAS). See Figure 8 for examples of product labeling.
When used according to instructions, this product meets ANSI Z359.14-2021, OSHA 1910.140, 1910.66, and 1926.502
Applicable standards and regulations depend on the type of work being done, and also might include state-specific regulations. Refer to local, state, and federal
(OSHA) requirements for additional information concerning the governing of occupational safety regarding Personal Fall Arrest Systems (PFAS).
American National Standards Institute (ANSI) and Occupational Safety and Health Administration (OSHA):
The SRLs covered in this manual meet ANSI Z359.14-2021, and Occupational Safety and Health Administration (OSHA) regulations 1910.140, 1910.66,
1926.502
. ANSI requires SRLs be classified according to their intended use and are tested either as Class 1 or Class 2 units. Dynamic performance testing
begins by installing the SRL in a controlled test environment. With the SRL attached to a suitable anchorage, the lifeline constituent is attached to a test weight.
The weight is then dropped to simulate a fall arrest event.
NOTE: SRL must be tested in all installation configurations allowed per its user instructions.
Test results are recorded.
Parameters recorded are:
•
Arrest Distance (AD)
•
Average Arrest Force (AAF)
•
Maximum Arrest Force (MAF)
The Arrest Distance is the total vertical distance required to completely arrest a fall. The Arrest Distance includes the deceleration distance and the activation
distance. The Average Arrest Force is the average of the forces applied to the body and the anchorage by the fall protection system. The Maximum Arrest Force is
the maximum amount of force that may be applied to the body and the anchorage by the fall protection system. These tests are conducted in ambient conditions.
The units must also be tested in extreme atmospheric conditions. There are three conditions: Cold, Hot, and Wet (Units saturated in water and tested). Separate
units may be used for each test. All test results are recorded. This test data is then used to establish the fall clearance guidelines published in this user instruction
manual.
Class 1 and 2:
Class 1:
Self-retracting devices which shall be used only on overhead anchorages and shall be subjected to a maximum free fall of 2 feet (0.6 m) or less, in
practical application.
Class 2:
Self-retracting devices which are intended for applications wherein overhead anchorages may not be available or feasible and which may, in practical
application, be subjected to a free fall of no more than 6 feet (1.8 m) over an edge.
When the SRL is anchored overhead of the user, ANSI Z359.14-2021 specifies that both Class 1 and Class 2 SRLs shall have an arrest distance of less
than 42 in. (1.1 m). Average arrest forces must not exceed 1,350 lbs. (612.35 kg). Conditioned testing of the units allows slightly higher Average Arrest
Forces of 1,575 lbs. (714.41 kg), but Maximum Arrest Forces must always remain below 1,800 lbs. (816.47 kg).
When dynamically tested in accordance with requirements of ANSI Z359.14-2021, Class 1 and Class 2 Self-Retracting Devices must have an AAF of
1,350 lbs. (612.35 kg) or less, and an AD of less than 42 in. (1.1 m).
Class 2 SRL labels must include fall clearance table illustrations that include a diagram of the axes shown on the table. These labels shall be affixed to the
product. Please see Section 10 of this user instruction manual for how to calculate your Minimum Required Fall Clearance (MRFC) using the affixed labels.
Classification information found on product labels is based on test results. Table 1 indicates the SRLs covered in this manual. NOTE: Arrest distance is
one of several parts of the Minimum Required Fall Clearance (MRFC). MRFC is discussed in detail in Section 10. OSHA requires an SRL limit the free fall
to 2 feet (0.6 m) or less. If the maximum free fall distance must be exceeded, the employer must document, based on test data, that the maximum arresting
force will not be exceeded, and the personal fall arrest system will function properly.
3.0 APPLICABLE SAFETY STANDARDS
Thank you for purchasing a Safewaze Self Retracting Lifeline (SRL). This manual must be read and understood in its entirety and used as part of an
employee training program as required by OSHA or any applicable state agency. This manual and any other instructional material must be provided to the user(s)
of the equipment. The user must understand how to use the SRL safely and effectively, as well as any related Personal Fall Arrest System (PFAS) components.
1.0 INTRODUCTION
2.0 APPLICATION
Safewaze SRLs are intended for use as part of a complete personal fall arrest, restraint, work positioning, suspension, or rescue system. Safewaze SRLs are
designed for a
single user
whose weight (including clothing, tools, and equipment) is:
ANSI
130-310 lbs. (58.96-140.61 kg)
OSHA
Up to 420 lbs. (190.51 kg)
