Fall arrest mode:
If workers cannot be protected from falls by guardrails or travel restraint, they can be protected
by one of the following methods:
-
fall-restricting system
-
fall-arrest system.
In the event of a fall, these systems must keep a worker from hitting the ground, the next
level below, or any other objects below.
A fall-restricting system
A fall-restricting system is designed to limit a worker’s free fall distance to less than 0.6 metres (2 feet). One
method to comply with this is to use a Self Retracting Lanyard that is set up to adequately limit a workers fall
distance. Self Retracting Lanyards should be used with a CSA approved personal shock absorber, CSA
Z259.11-M92 (R2003) wherever possible, as long as this will not increase the fall distance and allow the
worker can hit an obstacle or a lower level.
Another method would be to use a short lanyard that would not allow more than 2 foot free fall.
Note: every precaution should be taken to reduce the free fall as much as possible at all times
A fall-arrest system
Must include a CSA-approved full body harness; CSA 259.10-06 (R2010)
Shock absorbing lanyard conforming to CSA Z259.11-M92 (R2003)
Safety lanyard conforming to CSA Z259.11-05 (R2010). The rope must be adjusted in such a way not to
allow free-fall of more than 4 feet (1, 2 meters).
NOTE
: sharp edges must be protected in such a way to avoid damage to the vertical lifelines or lanyards.
The user must install protector cushions on all sharp edges. (See figure 3)
