METERS

5. WHO IS AT RISK ?
•Work near unprotected open
edges or floors
•Work near unprotected
penetrations or openings in
floors or walls
•Work near unguarded shafts
or excavations
•Work near or from unstable
structures
•Work where a person could
fall into water, acid or
poisonous solutions.

7. WHO IS AT RISK ?
•Work on, or near, fragile or
brittle surfaces
•Work where a person could
fall onto sharp or projecting
objects such as exposed
reinforcing steel, a picked
fence, broken glass etc..
•Work where tools,
equipment or material could
be dropped to a person
below.

10. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Identify all tasks that could involve
someone falling
•Idendify any objects that could fall onto
someone
•Identify anything dangerous that anyone
could fall into or onto
•Identify any other risks to workers
•Identify any risks to the general public
What do I need first?

How do I control the Risks?
Spot the Hazards

17. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
Spot the Hazards
•If working on as roof, consider the pitch, whether it is slippery or
reflective, and the capacity of working surface to support the
intended road.
•Training and experience of workers, e.g. New or inexperienced
workers may be involved and the level of supervision needed may
have to be considered.
•The weather conditions, e.g. poor lighting, making unguarded edges
and openings difficult to see.
•Anchorage points for the attachment of safety harnesses.
•The width of work area.

18. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Obstructions in the work area caused by equipment, building
materials, tools and rubbish
•Uneven work sufaces
•Wet, oily, glazed or otherwise slippery work surfaces
•The extent and type of work to be undertaken
•Unstable objects such as sheets of plaster that may be caught by the
wind
•Large and heavy equipment that may need to be raised to the work
surface
Spot the Hazards

19. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•The necessity to move from one height to another
•The number and movement of everyone on site
•Inadequate safety systems, e.g. No procedures for performing tasks
safely or for using personal protective equipment
•The possibility of debris or objects falling onto others
•The possibility of someone falling into or onto something dangerous
•The lack of or inadequacy of warning notices
Spot the Hazards

20. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
Assess The Risks
•How likely is the hazard to
cause harm to someone?
•What is the worst possible
damage the hazard could cause
in terms of human suffering
and cost if you don’t resolve
problem?

21. Some things to consider:
•How many people are exposed to the risk?
•Sometimes it may be the amount of time workers spend on an activity
that creates the safety risk, rather than the nature of the work task itself,
e.g. prolonged exposure to hot sun could cause dizziness.
•Everyone is different.A hazard may pose more risk to some people than
others because of differnces in physical strength, experience, training
etc..

Assess The Risks

22. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
Fix the Problem
Once hazards have been identified and the risk assessed, you
need to start thinking about how you can fix the cause of each
identified risk
Some problems may be fixed easily, while others will require
more effort and planning to resolve.It is therefore important to
concentrate on the most urgent hazards without neglecting the
simpler ones.That is, don’t focus on just the complex solutions, as
that could mean to overlook hazards that could be easily fixed, such
as rubbish that someone could trip over.
When it comes to controlling risk, some methods are more
effective than others. For example, it is far better to make sure there
are no obvious objects that can fall onto people than to put up as
sign warning of “falling objects”.

23. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
Evaluate the Results
Hazards and risks need to be managed on an ongoing basis,
especially where the weather is concerned.
Review your safety solutions regularly to make sure they are
effective. It is important to make sure your controls do not introduce
new hazards.
To assess the success of your risk control methods, talk to
everyone involved and consider the types of accidents that have
occurred in your industry. Be sure to seek advice from those affected
by the changes and include them in any modifications to their work or
work routines. It is also essential to consider training.

24. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Ladders
Ladders will only be
used for works of a minor
nature. Ladders will not be
used on elevated floor
levels near the perimeter of
the building where there is a
danger of a person falling.

25. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Guardrails
Guard rails must be fitted
to all elevated work
platforms. The guard rails
should be of a height and
construction to withstand
loads which could
reasonably be expected to
be imposed on them. Where
specifications are
prescribed by local
regulatory bodies for these,
they will be observed

26. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Fall Arrest Systems
Individual fall arrest
systems are classified as
personal protective
equipment, which means
these systems should be
used only after other
controls such as
elimination; isolation and
substitution have been
considered. The
appropriate standards and
codes of practice should be
applied when using this
system.

27. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Fall Arrest Systems
•You may want to apply a You may want to apply a
“TOTAL TIE OFF” or “TOTAL TIE OFF” or
“100% TIE OFF” system “100% TIE OFF” system

•100% tie offs are used on this project
and the operations are closely
monitored.
•These are usually used at very high
locations but may also be used where
access/egress is limited or where
platforms and guard rails are not
practical.

29. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Roof work
Protection must be provided for
all persons that are required to work
on roofs where there is a danger of
persons falling including:  
    
•through the roofing
material;
•from the edge of the roof;
•through skylights or
penetrations
•while accessing a roof.

30. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
Methods of protection available
include:
•scaffolding, guardrails
combined with existing
safety mesh where the
safety mesh is in sound
condition, purpose built
purlin platforms or trolleys,
purpose built roof ladders,
safety nets, catch
platforms.
•Where none of the above
systems are practicable,
individual fall arrest
systems.

31. HOW TO MANAGE THE RISKS OF FALLS
FROM HEIGHTS
•Protection of Openings
and Penetrations
Open sides of all floors,
roofs stairwells, lightwells,
lift shafts and any place
from which a person or
object could fall will be
securely covered with rigid
material or provided with
guard rails and toe-boards.
