12. ANCHORAGE STRENGTH
The application type determines the anchorage strength requirement. As per ANSI Z359.1 the necessary anchorage strength for the
following applications is listed below:
Fall Arrest: For this choose an anchorage that has strength capable of sustaining static loads of at least 5000 lbs. (23 kN), applied in
directions permitted by the system. However, if more than one fall arrest system is attached to the anchorage, then the strength required
has to be 5000 lbs. (23 kN) multiplied by the systems attached to the anchorage.
As per OSHA 1926.500 and 1910.66: Anchorages that are used for attachment of Personal Fall Arrest Systems (PFAS) shall be
independent of any anchorage being used to support or suspend platforms. They should be capable of withstanding a minimum load of
5000 lbs. (23 kN) per user attached. They should be designed, installed and used as part of a complete Personal Fall Arrest Systems

13. GENERAL LIMITATIONS OF FALL ARREST SYSTEM AND REQUIREMENTS
It is important to consider the below mentioned limitations before using or installing this equipment.
• KStrong SRL’s are meant for use by ONE person only. The capacity of KStrong SRL’s is from a minimum of 90 lbs. to a maximum
of 310 lbs. (140 kg) hence, the combined weight (clothes, tools, shoes etc.) of a person using this equipment should not be less
than 90 lbs. or more than 310 lbs. It is important to ensure that all the components in the system are rated to a capacity which is
appropriate to the application. (( Capacity as per ANSI 130-310 lbs. & as per OSHA 420 lbs.)
• Corrosion: The SRL should not be left in any environment for a long period of time, if it causes corrosion of its metal parts. It is
important to be cautious while working around corrosive substances like sea water, ammonium compounds, sewage, fertilizers,
and other such environments. Corrosive damage impacts the performance of the SRL, hence the inspection of the SRL should be
performed more frequently so as to check its functioning and performance.
• Locking Speed: The SRL requires an initial speed of retraction of the line to cause it to lock. However, this speed may not be
achievedifthereisanobstructedfall,orwhileworkinginconnedspaces.Workinginsuchconditionsmaylimitthespeedatwhich
the locking of the SRL is achieved. Special care is required where the SRL is used while working on low-pitched roofs. Here the
user may slide on the roof slope, rather than have a direct fall. This could also hamper the SRL locking mechanism. A clear path is
required to ensure that the SRL’s locking mechanism is activated.
• Free Fall: As per ANSI Z359.1, the personal fall arrest systems used with this equipment must be rigged in such a way that the
free fall does not exceed 6 ft. (1.8 m). Ensure that there is no slack in the lifeline, while using the SRL. Also, never extend the
length of the lifeline by connecting a lanyard to it. Do not anchor the SRL at or below your foot level as this will increase your free
falldistancebeyondthepermissiblelevelsasspeciedbyOSHA.Additionally,thiscouldalsocauseexcessiveloadimpactonthe
SRL, thereby exceeding its capabilities
to safely arrest a fall. Contact KStrong
for any further information required.
• Fall Clearance: There should be
sufcient clearance below the user to
allow the system to arrest a fall so as
to prevent the user from striking the
ground or any other obstruction. The
clearance required is dependent upon
the following factors:
• Anchorage location
• Type of connecting subsystem
used (energy absorbing lanyard,
SRL, etc.).
• The minimum fall clearance required when a SRL is used is six
feet from the working level, subject to the condition that the SRL
is attached directly over the head of the worker.
• Swing Falls: Swing fall occurs when the position of the anchorage
point is not directly above the point where a fall occurs. In such a case
if a fall were to occur, it will result in pendulum swing of the fall victim
and may also cause them to strike nearby objects with a force. This
may cause serious injury or even death. Such swing falls may be
minimized by ensuring that the anchorage is directly overhead, and by
