Fall Clearance:
There should be sufficient 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:
Ÿ
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), and as per ANSI Z359.13, it should not exceed 12 ft. Restraint
systems must be rigged in such a way that no vertical free fall is possible. Work positioning systems are required
to be rigged in a way that the free fall does not exceed 2 feet (0.6 m). Personal riding systems must be rigged so
that there is no vertical free fall possible. Climbing systems must be rigged so that free fall is less than 18 inches
(46 cm). Rescue systems must be rigged in such a way that there is no vertical free fall. Contact KStrong for any
further information needed.

If the only available anchorage is situated below the attachment on the harness, and if there is a risk of fall, then it is
essential to use a lanyard provided with a properly rated energy absorber. It is important to ensure that there is sufficient
fall clearance below the user before using a shock absorbing lanyard. If the weight of a wearer is 220 lbs. and the fall
factor is two, we can calculate the fall clearance (which will be equal to the stopping distance H (2L+ 5.74 ft.) + an
additional
distance of 3.28 ft.

PERIODIC EXAMINATION
In corrosive environments or in areas near seawater, metallic connectors and hooks have a greater chance of corrosion
and rusting. Hence, the frequency of their inspection must be altered so as to check their functioning and performance
more frequently.
Always keep the instructions provided with the product. Take the information from the markings on the product and
enter this information in the identification sheet. To ensure the safety of the user, it is essential to check the condition of
the equipment through the periodic examination of the product. This equipment must be examined by a qualified person
at least once every six months, strictly complying with the manufacturer's instructions. Also, record the previous check
on the attached sheet. If the equipment is in heavy usage or is used in a harsh environment, then the frequency of
inspection should be increased in accordance with regulations. Check also that the markings on the product are legible.
