INTRODUCTION
Application
The
GRIZZLY
HERCULES is a Mobile Anchoring System for fall protection that when used correctly and
according to the directions in this manual and in compliance with all the regulations and standards, (These may
change from Province to Province or State to State); will afford adequate fall protection for workers while working on
flat roofs and similar structures.
NOTE:
All Provinces and States have specific training requirements for all users of fall protection equipment. This manual is to
be used as a tool for training and in no way replaces training of workers by qualified persons
RESTRICTIONS
NOT FOLLOWING THE RULES OUTLINED FOR THE USE OF the
GRIZZLY
HERCULES Mobile Anchoring
System may lead to serious injury or death.
In order to ensure the efficiency of the HERCULES Mobile Anchoring System, the following guidelines must be
respected:
1.
Minimum Safe Distance Required, A competent person must ensure that the system is set up in
such a way that considering the distance of the fall, the HERCULES Mobile Anchoring System
will only be used in fall arrest mode on roofs or structures with enough minimum safe distance
from the ground or a lower level to prevent the worker from falling far enough to hit the ground or
the lower level. There should be at least a 3 foot margin of safety added to the fall distance
calculations. A Competent Person must always do the necessary calculations to ensure that the
minimum height restrictions are adhered too. Note: There are different limits to the amount of free
fall allowed in some jurisdictions. There are a number of ways to calculate this distance including a
“Splat Bag” or other equipment available from fall protection equipment suppliers or by
calculating the distance taking into account the length of the lanyard and shock absorber – one of
these calculations is described in (See figure 1)
