which should be read and properly understood prior
to installation of this system.
1. The hierarchy of risk control must be followed at all times.
2. Professional guidance on the design and set out of this
system should be obtained prior to installation.
3. Certain environments produce acidic atmospheric
conditions which are detrimental to steel structures and
surfaces. Any acidic environment must be assessed and
certified by persons prior to installation of this system.
4. A cage fall protection system must start 2000mm -
2200mm from the lower ladder landing.
Must be read prior to installation
5. The cage is to extend a minimum of 900mm above the
top exit point of the ladder.
6. For maximum fall protection effectiveness, a cage fall
protection system needs to be installed at 75˚.
7. A caged fall protection system mounted at 90˚ provides
very limited fall protection. A ladder fall arrest system is
recommended in conjunction with the ladder cage in this
situation.
8. A rung ladder requires a lock off gate to prevent
unauthorised entry.
It is important to note that the lower the hierarchy
of control, the greater the skill of the operator
required and therefore is least preferred compared
with a higher hierarchy requiring minimal operator
skill and less risk of operator injury as a result of
incompetence.
