Answer:
Fall Arrest System
Fall arrest systems refer to the use of multiple approved safety equipment components
designed to be interconnected and rigged to arrest a free fall, which include some or all of
the following:
Anchorage
Horizontal and/or vertical lifelines
Inertia reel
Lanyard
Retractable lifeline
Rope grabs
Wire grabs
Rail system
Shock absorbers
Body harnesses
Lanyard
A lanyard connects a harness to an anchorage point or static line.
Karabiner
Metal connectors that can be attached to anchorage points.
Easily attached/detached, self-closing and requiring at least two consecutive deliberate
manual actions to open.
Restraint Line
A restraint line secures a worker to a point of anchorage and is used to prevent a person
from reaching a point from which they could fall.
Static Line
A static line is a horizontal line to which a lanyard may be attached and is designed to arrest
a free fall.

2. Which type of document would you refer to for inspection, maintenance and capacity of
fall arrest equipment?
Answer:
Manufacturer’s guidelines
3. When is a “Work at Heights Permit” required?
Answer:
Any work undertaken at a height greater than 2 metres, including the use of EWPs and work
cages, requires you to obtain a Working at Height Permit prior to commencement.
4. Who is permitted to issue a “Work at Heights Permit”?

5. Describe how you can avoid manual handling injuries when shifting tools and
equipment.
Answer:
Using appropriate lifting/transporting equipment, such as hand a trolley.
6. Why is it important to remove all the tools, equipment and materials after completion of
the working at heights task?
Answer:
There is a great possibility that if tools, equipment and/or materials are left behind they may
potentially fall on personnel below; or may cause damage to any mechanical moving parts or
working systems located at the working at height site.

Answer:
The Hierarchy of Controls provides a priority list of hazard control measures, which
emphasises controlling a hazard(s) at its source, with the control measures listed in order of
effectiveness.
13. Describe the method of control for the following “Hierarchy of Controls”
Answer:
The first one is provided as an example:
Elimination: modify process, method or material to eliminate hazard completely.
Substitution: replace process, material or substance with a less hazardous one.
Isolation: isolate the hazard from persons by safeguarding, or by space, or time
separation.
Engineering: plant or work process redesigned to reduce or eliminate risk.
Administration: establish procedures, work instructions and training.
PPE - Using appropriately designed and fitted personal protective equipment where
other controls are not practical.
