Working at HeightsShow me your Permit
Not every place needs a permitBut workers must consider always the
following:CSA standards (or equivalent):
• Connecting Components for Personal Fall Arrest Systems CAN/CSA Z259.12-01
• Safety Belts and Lanyards CAN/CSA/Z259.1-95
• Full Body Harnesses CAN/CSA/Z259.10-M90
• Fall Arresters, Vertical Lifelines and Rails. CAN/CSA-Z259.2.1-98
• Self-Retracting Devices for Personal Fall-Arrest Systems. CAN/CSA-Z259.2.2-98
• Descent Control Devices. CAN/CSA-Z259.2.3-99
• Shock Absorbers for Personal Fall-Arrest Systems. CAN/CSA-Z259.11-M92
• Fall Restrict Equipment for Wood Pole Climbing. CAN/CSA-Z259.14-01
The regulations give rise to the following concerns
The regulation relating to fall hazards apply where a worker is exposed to any of the following hazards including but not limited to:
• falling from a height of more than 3 metres (approx. 10 feet);
• falling into operating machinery;
• falling into water or another liquid;
• falling into or onto a hazardous substance or object;
• falling though an opening in a work surface.

Working at Height
Work at height is work in any place, including a place at,
above or below ground level, where a person could be
injured if they fell from that place.
Access and egress to a place of work can also be work
at height.
It does not include stairways or slips or trips on the level.
What is Working at Height
Any persons involved with the design or erection of fall
prevention or fall protection equipment must be subject to formal
competence checks in order to ensure that they possess the
necessary training, competence and qualifications to perform
those tasks before being allowed to work on site.
Working at Height
Working on roof.
Working on ladders.
Working at ground level adjacent to
an open excavation.
Working from temporary work
platforms- scaffold, MEWP, tanks
etc.
Examples of working at height
Working at Height
Planning, Organizing and Competence
Work at Height must be:
Properly planned and
communicated to all, including
contractors before work
commences.
Appropriately supervised by
competent people.
Not carried out if weather
conditions jeopardise safety.
Those working at height must be:
Competent and entered onto a
register.
Or, if being trained, supervised
by a competent person.
Whilst passing this training module counts towards proving
competence, annual practical training, experience and
attendance at induction training, toolbox talks and risk
assessment meetings provides further evidence towards proof of
competence.

MEWP (Mobile Elevating Work Platforms)
A general term used for scissor lift, aerial
platform, or an extensible or articulating boom
aerial device (either self-propelled or vehicle-
mounted) used for the purpose of positioning
personnel, their tools and necessary materials to
elevated work locations.

falling or pinned by a nearby structure.
contact with electrical lines or equipment.
When working on sloping
roofs:
Use proper roof
ladders.
Wear a safety harness.
When working on fragile
roofs:
Use crawling boards.
Ensure a warning sign is
displayed at all access
points.
Control of Hazards
Working on roofs
Control of Hazards
Ladder Safety
May be used for light tasks of
low risk and short duration (in
conjunction with a safety
harness); or access and egress
to a work platform.
Must be secured to prevent
slipping– sideways and outwards.
Should be Installed at an angle of
4:1 (or 75°).
Must extend approx. 1 m above
working platform (if applicable).
Control of Hazards
Scaffolds
All scaffolds must be designed,
erected, altered and dismantled
by a competent person.
Once erected, scaffolds must be
inspected by a competent
person:
Before first use.
After substantial alteration.
After any event likely to have
affected its stability e.g.
after strong winds.
At least once every 7 days
inspections must be recorded
and a Scaf-tag system or
equivalent used to indicate
inspection status. In the event
that faults are found, the tag
must be pulled and the scaffold
taken out of use until repaired.
Control of Hazards
Mobile Elevating Work Platforms (MEWP)
MEWP can provide safe access and
safe working at heights, and are
often safer than ladders or other
access equipment.
Equipment must be thoroughly
tested & examined by a competent
person before first use & at least
once every six months.
Equipment must be inspected
daily by operators / users and
repaired if defects found.
Operators must be trained in its
use, inspection and emergency
procedures.
Baskets must have barriers /
boards (approx. 1.1 m in height
and toe boards / kick-plates).
Operators must wear a safety
harness - attached to the basket.
Steps for Safe Working at Height
1: Risk Assessment.
2: Hierarchy for Safe
Working at Height.
3: Planning and Organizing.
4: Ensure that those working
at height are competent.
5: Use appropriate Work
Equipment.
6: Manage the Risk from
Falling Objects.
7: Inspect and Maintain the
Work Equipment and
Workplace.
Steps:
Steps for Safe Working at Height
Step 1: Risk Assessment
Each assessment should be
proportionate to the risks involved
but factors to consider include:
Environment and
conditions – location, access,
egress, weather and ground
conditions, other activities.
Task to be performed -
extent of the task, its
complexity, duration,
frequency.
People involved - numbers,
degree of exposure to the risk,
competence of workers
involved, (including
Contractors),levels of
supervision required.
The quality of the site
induction program, were
Alstom’s expectations for
working at height explained
adequately?
Fall Prevention
When an elevated work location cannot be accessed
safely from a ladder or protected work platform or when
the installation of guardrails is infeasible, fall restraint or
fall arrest systems may be used.
Personal fall-arrest system arrests a fall.
Personal fall-restraint system prevents a fall.
Fall Protection Equipment
Fall Prevention
A personal fall-arrest
system consists of an
anchorage, connectors,
and a full-body harness
that work together to stop
a fall and to minimize the
arrest force. Other parts of
the system will include a
lanyard, a deceleration
device, and may include a
lifeline.
A personal fall-restraint
system prevents a worker
from reaching an
unprotected edge and thus
prevents a fall from
occurring. The system
consists of an anchorage
point, connectors and a
body harness.
Fall Protection Equipment
Fall Prevention
When using a fall arrest system, the fall distance
calculation must account for the length of lanyard,
deceleration distance, the height of the person wearing the
equipment (or the height of the D-ring attached to the back
of the harness), the position of the anchorage point,
lanyard or rope elongation and a safety factor.
Fall Distance Calculation
Emergency Rescue Plan
A rescue plan must be
developed where a safety
harness is being used as a
control measure & when
personnel may not able to self
Rescue.
A person suspended in a
harness may be unconscious
within five minutes and dead
within fifteen minutes if help
is not immediately available.
Any method statement must
include a rescue plan that
considers how an injured
worker could be safely
recovered. Speed of response
is an essential consideration.
The emergency plan must be
simulated annually.

Control
• Avoid working at heights, whenever possible.
Access Equipment
• Using the appropriate type of access equipment and controls means…
Access equipment (e.g. MEWPs, ladders) and anything attached to it and used in lifting is to be of adequate strength and stability for each load, and
is to be designed and erected in a way that prevents the user from being crushed, trapped, struck or falling from the carrier.
Safe Working Procedure - Working at Heights
Control - Access Equipment (cont’d)
• Additional fall arrest equipment is to be available when
the risk of falling from the carrier is not eliminated;
by the design or
by the erection of the access equipment.
• Ensure training and fitness requirements are met.
• New people must work under close supervision even
after full training has been provided.
Remember: Avoid working at heights, if possible.
Markings/ Warnings.
• All access equipment is to conform to the relevant
national statutory requirements and bear the
statutory markings (e.g. CE marks, Safe Working
Load).
• All markings and warnings are to be clearly visible,
audible (where appropriate), easily understood and
conform to nationally or internationally recognised
standards.
