MSA Latchways GTFA Instrucciones Para El Usuario página 5

2 Intended use and product limitations
The Latchways GTFA is designed to arrest the fall of a User in
conjunction with a Latchways VLL. The system or device energy
absorber reduces the load applied to the body to 6 kN (1,350 lbf) or
less in the event of a fall. Lifeline systems may be designed either
with or without integral energy absorption. It is therefore essential
that the User ensures that the individual device is compatible with
the system (Table 1). If there is no system energy absorption then
only devices that include an energy absorber shall be used.
The device has an anti-inversion mechanism which prevents it
being used on the Latchways VLL if there is an attempt to use it
upside down.
The lower end of the lifeline includes a termination (bottom
anchor) that prevents the fall arrester passing through the
termination. When the lifeline is installed, the bottom anchor
provides a tensioning feature for the lifeline and an indicating
feature once the correct pre-tension is applied.
The required minimum distance below the User's feet and the
working platform is 2 m (6'6"). Below 2 m (6'6") the User may not
be protected against hitting the working platform or obstacles
below. Therefore, extra care must be taken when ascending /
descending the first 2 m (6'6").
Temporarily disabling or manually handling the lock/release
mechanism of the device during ascent or descent may hinder the
safe operation and diminish the effect of the braking mechanism.
The Latchways devices have been subjected to an additional series
of tests devised by TUV/NEL. These tests were conducted using
71 kg (156 lbs) and 100 kg (220 lbs) anthropomorphic test dummies
with different body postures (reference NEL certificate no. MTHH).
Maximum Rated Load: Maximum single User mass is 150 kg
(including tools and equipment carried). Total system User mass
is determined by the device type and system configuration as
illustrated in Table 1.
