WERNER R430011 Self Retracting Lifelines

Product Information

The Self-Retracting Lifelines with Leading Edge capability is a fall protection system that complies with the ANSI Z359.14 standard and OSHA 29 CFR 1910 and 1926 regulations. It is designed for a single user and is not recommended for use near sharp, jagged or abrasive structural edges. The user instructions must always be available to the user, and failure to follow all instructions and limitations may result in serious personal injury or death. The SRL-LE must be inspected for wear, damage, and other deterioration before each use, and defective components must be immediately removed from service.

Product Usage Instructions

1. Before using the SRL-LE, employees must be trained in accordance with the requirements of OSHA 29 CFR 1910.30 and 1926.503 in the safe use of the system and its components.
2. The complete fall arrest system must be planned (including all components, calculating fall clearance, and swing fall) before using.
3. Users must have a rescue plan and means to implement it, providing for the prompt rescue of the user in the event of a fall, or assuring that the user is able to rescue themselves.
4. Store the SRL-LE in a cool, dry, clean environment, out of direct sunlight when not in use.
5. After a fall occurs on the system, immediately remove from service until a competent person inspects and approves its continued use.

Note that minors, pregnant women, and anyone with a history of back or neck problems should not use this equipment. Also, only use components rated for the same weight capacity and do not use combinations of components or subsystems that may affect or interfere with the safe function of each other. Caution must be taken when using SRL-LE near moving machinery or electrical hazards, and if used in conjunction with a cross-arm strap anchorage connector, other anchorage extension, horizontal lifeline, or extended D-ring, the additional length of the anchorage connector, extended D-ring, or sag from the lifeline must be taken into consideration during the clearance calculation process.

WARNING! Use of this device in an orientation such that the constituent line may contact a sharp, jagged or abrasive structural edge is inherently dangerous, and such use should be a last resort.

ANCHORAGE REQUIREMENTS

ANCHORAGES
All anchorages to which the SRL-LE attaches must meet the requirements of ANSI Z359.2 and OSHA 29 CFR 1910 and 1926.

OSHA states:
Anchorages used for attachment of personal fall arrest equipment shall be independent of any anchorage being used to support or suspend platforms and capable of supporting at least 5,000 pounds (22.2 kN) 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; and under the supervision of a qualifi ed person.
ANSI Z359.2 states that anchorages selected for fall arrest systems must have a strength capable of sustaining static loads, applied in all permitted directions by the system:

• A) no less than 5,000 pounds (22.2 kN) for non-certifi ed anchorages; or
• B) at least two times the maximum arresting force for certifi ed anchorages;
• C) according to ANSI Z359.6, Specifi cations and Design Requirements for Active Fall Protection Systems.

When more than one personal fall arrest system is attached to the anchorage, the strength in (A) or (B) must be multiplied by the number of personal fall arrest systems attached to the anchorage.

CONNECTION REQUIREMENTS

COMPATIBILITY LIMITATIONS
All connecting subsystems must only be coupled to compatible connectors. OSHA 29 CFR 1910.140 and 1926.502 prohibit snap hooks from being engaged to certain objects unless two requirements are met: snap hook must be a locking type and must be “designed for” making such a connection. Under OSHA “designed for” means that the manufacturer of the snap hook specifi cally designed the snap hook to be used to connect to the equipment in question. The following connections must be avoided because they can result in rollout* when a non- locking snap hook is used:

• Direct connection of a snap hook to horizontal lifeline.
• Two (or more) snap hooks connected to one D-ring.
• Two snap hooks connected to each other.
• A snap hook connected back on its integral lanyard.
• A snap hook connected to a webbing loop or webbing lanyard.
• Improper dimensions of the D-ring, rebar, or other connection point in relation to the snap hook dimensions that would allow the snap hook keeper to be depressed by a turning motion of the snap hook.

Rollout : A process by which a snap hook or carabiner unintentionally disengages from another connector or object to which it is coupled.
