Work at Height
The Work at Height Regs. 2005
•
Came into force on 6th April
2005.
•
These regulations
consolidate good practice
and current legislation
•
The good old days….
What is “Work at Height”?
•
A place where a person can be injured falling
from – even if at or below ground level.
•
•
Work includes moving around at a place of work
Does not include travel to and from a place of
work
The Regulations apply:-
•
To all work at height where there is a risk of a fall
liable to cause personal injury
•
Duty applies to employers, self employed and
any person who controls the work of others to
the extent they control the work
General Duties
•
•
•
•
•
•
•
Work must be properly planned and organised
Consider weather conditions
Ensure workers are trained and competent
Place of work is safe
Equipment is inspected
Risks from fragile surfaces are controlled
Risks from falling objects are controlled
Duties on Employer: -
•
Do all that is reasonably practicable to prevent
anyone falling
•
•
•
Avoid work at height if possible
If not take all steps to prevent falls
Take all steps to reduce distance of fall (and
consequences)
Planning
•
Ensure that no work is done at height if it does
not have to be
•
Ensure work planned, supervised and
undertaken in as safe a way as is reasonably
practicable
•
Consider risk assessments carried out
Planning
•
Postpone work if weather endangers health or
safety
•
•
Ensure all workers are competent
•
Train those working at height now to avoid falling
or minimise injury to themselves should they fall
If Trainees must be supervised by a competent
person
Planning
•
•
Place of work (including access) must be safe
Must have features to prevent a fall
UNLESS
The worker would then be unable to do the work safely
due to demands of work, equipment used and working
environment
BUT
The Employer must provide equipment to prevent a fall
Duties on Employee: -
•
•
•
•
Report any safety hazard to employer
Use the equipment supplied correctly
Follow any training
Follow instructions – unless you think that would
be unsafe
Equipment: -
•
•
•
•
Most suitable
Collective protection more that personal
Consider working conditions
Consider risks to safety of all those at the
workplace
What Do The Schedules To The Regulations
Cover?
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Schedule 1
Existing places of work and means of access for work at height
Schedule 2
Collective fall prevention (e.g. guard rails and toe boards)
Schedule 3
Working platforms (includes scaffolding)
Schedule 4
Collective fall arrest (e.g. nets, airbags etc.)
Schedule 5
Personal fall protection
Schedule 6
Ladders and step ladders
Schedule 7
Inspection reports
Schedule 8
Revocations (cancellations, dissolution)
Competency
Those working at height should be
competent, with the appropriate:
• Skill
• Knowledge,
• Ability,
• Training
• Experience,
• Have authority to carry out the work
task.
• A truly competent person knows
their LIMITATIONS
Risk Assessment
•
The Work at Height Regulations are risk
based, i.e. if a risk is present the
regulations apply.
•
Regulation 3 of the Management of
Health and Safety at Work Regulations
still applies.
•
Do a Risk Assessment.
Avoid – Prevent – Minimise
When planning work at height follow the
Hierarchy of Control Methods.
•
AVOID work at height,
•
PREVENT falls,
•
MINIMISE the distance and
consequences of falls.
Types Of Work Equipment
Remote operated equipment
Long handled tools
AVOID
Permanent engineered platforms
Scaffolding (tube & fitting)
M.E.W.P.’s
Scaffold towers
Temporary edge protection
PREVENT
Personal Fall Restraint systems
Collective Fall Arrest systems
Personal Fall Arrest systems
Ladders
MINIMISE
Select the right work equipment
Always consider:
• Working conditions,
• Access & egress,
• Distance & consequence a of fall,
• Duration & frequency of work task,
• Ease of rescue & evacuation,
• Risks during installing, using & removing the
proposed equipment.
Select the right work equipment
COLLECTIVE PROTECTION

PERSONAL PROTECTION
•
Safe working platforms before personal work
restraint equipment.
•
Nets & airbags before personal fall arrest
equipment.

What else to consider?
•
•
•
•
•
•
Avoid fragile surfaces,
Assess strength of platforms,
Prevent falling objects,
Inspect equipment,
Inspect place of work,
Danger areas.
AVOID
If you don’t have to
go up there, DON’T
GO!
•
Is the work task
necessary?
•
Can the problem be
engineered away?
•
Is the use of special
tools possible?
PREVENT
Prevent falls by using or creating
safe working areas.
• Use an existing place of
work or means of access
• Use the most suitable way of
working
• Select the most suitable
equipment
• Proactively prevents falls
from happening by using
guardrails, warning lines,
hole covers
MEWPS - example
•
The MEWP is designed
to provide a temporary
working platform which
can be easily moved
from one location to
another.
•
It’s particularly suitable
for short duration work
where the use of a
ladder would be unsafe
and erection of
scaffolding would be
time consuming and
impracticable
MINIMISE
Minimise the distance and consequences
of falls.
• Use the most suitable way of
working,
• Select the most suitable equipment,
• Take other measures to prevent
injury,
e.g. instruction, information, training & supervision.
Air Bags / Bean Bags
•
Designed to reduce number of injuries and
deaths in falls from height.
•
Cushioned re-usable air bags - 0.55m high
- weigh less than 7kg each.
•
Can be filled with foam enabling them to
retain original shape.
•
They provide a yielding surface on which
to fall.
•
Position bags correctly before work
commences.
•
Clip bags together to prevent separation
when falling on the junction.
Air Bags / Bean Bags
•
They should be checked when repositioned or after a fall to ensure
there’s no damage.
•
Other control measures must be in
place to prevent falls.
•
•
Bags are a last resort.
N.B. a fall, even on a ‘safe’ place could
be very stressful and traumatic.

In this situation there is a
danger of swinging past the
vertical should a fall occur.
Correct positioning of the
upper anchor connector
would eliminate this.
Use of Fall Protection P.P.E.
•
If you issue Fall Arrest Equipment then
you MUST consider rescue
Rescue From Height
Always consider:
•
•
•
•
•
•
Type of fall (straight drop or swing),
•
Relying on County Fire Service is unacceptable
Distance of free fall & impact force,
Time to effect rescue,
Lift back up or lower down?
Medical treatment/Hospitalisation,
Training for rescue personnel & regular practice
sessions,
