EXTERIOR SCAFFOLDING SAFETY GUIDELINES
REQUIREMENTS FOR ACCESS FRAME
SCAFFOLDING
• A scaffold must be erected, altered, and
dismantled by qualied workers or under
the direct supervision of a qualied person.
The qualied person must ensure that the
erection is carried out properly, and that
the correct components and materials are
being used. All equipment must be inspected
before use to ensure that it is in good repair
and suitable for the intended use.
• The base must be rm and level enough to
support the load of scaffolding, workers, and
materials. Sills and base plates are required
on any soil or unstable ground condition, or
where any levelling adjustment is needed.
The sill must be sound, rigid, and capable
of supporting the maximum loads without
settlement or deformation.
• Levelling jack base must be adjusted within
the limits specied by the local regulation.
• The frames must be plumb and level and
spaced to adequately support the loads.
• If uplift could cause the components to
separate, locking pins must be used and the
components secured. Uplift might be caused
by the action of wind on a secured deck or
by the leverage action of a cantilever side
bracket on the scaffolding. All joints must
be pinned on rolling scaffoldings and free-
standing towers.
• With a rolling scaffolding or free-standing
tower, the platform height must not exceed
three times its smallest base dimension (3 to
1 rule).
• A scaffolding built above the 3 to 1 rule must
be effectively guyed or secured to a building
or structure to prevent overturning. The guying
of a scaffolding may require the direction of a
professional engineer.
• Guardrails must be installed on all open
sides of the platform where a person could
fall a distance of 10 ft. or more. The top
rail must be placed 40-44 in. above the
work surface. An intermediate rail must be
placed halfway between the top rail and
the toeboard, if one is provided, or halfway
between the top rail and the work surface if
no toeboard is provided.
• Toeboards must be installed on all the open
sides of a platform where it is possible for
tools and or materials to roll off. The top of
the toeboard must be at least 4 in. above the
platform. If loose materials are to be stacked
above the height of the toeboard, then the
toeboard must be increased in height or
mesh panels must be installed to prevent
materials from falling off the scaffolding.
BEFORE ERECTING ACCESS FRAME
SCAFFOLDING
• What will the scaffolding be used for? For
example, light duty (one or two workers;
painting a wall), or heavy duty (several
tradespersons, with large and heavy materials
on the platform)?
• How high will the scaffolding be? Will it be
erected in one operation or as the work
progresses?
• Is the ground rm? Can it support the loads
from the scaffolding, workers, and materials
on it?
• Will the scaffolding need to be tied in? How
will this be done? Will the ties be moved as
the work progresses?
• Is the scaffolding likely to be covered
or enclosed as a protection against the
elements? Is there provision for adding
additional ties to the adjoining structure?
• What will be the method of access and
egress? For example, a sloping ladder,
vertical ladder, built-in stairway, or direct from
the oors of the building structure?
• On a multi-level scaffolding, how many levels
will be loaded with materials at one time?
Will an engineer be required to make the
calculations for the total anticipated loading
and possibly design the scaffolding and the
sills?
• If a rolling scaffolding is required, consider
ground surface, height restriction (3 to 1 rule)
hazards when moving (such as power lines,
projections from the building, and potholes).
EQUIPMENT INSPECTION
YOU MUST INSPECT THE EQUIPMENT YOU PLAN
TO USE TO MAKE SURE THAT IT IS IN GOOD
REPAIR AND SUITABLE FOR THE JOB. CHECK
THE FOLLOWING:
• Sills: suitable size and strength for the loads.
Not split or rotten.
• Frames: no cracks in the welded joints. No
kinks or dents in the top or bottom cross-
members. Legs plumb and square with the
cross-members. Brace locks in good working
order. Coupling pins in place and secured to
the frame.
• Cross braces and diagonal braces: straight
with no bent ends. Pivot connection in good
working order. No excessive rust.
• Scaffold planks: no split ends, saw cuts,
notches, protruding nails, excessive warping.
No contamination that may affect the integrity
of the plank, such as oil, chemicals, and burns.
(If you have any doubts about the strength of
the plank, you may need to have it load-
tested).
• All aluminium or with plywood deck
platforms: not mis-shaped or cracked.
Locks working. All bolts and screws in place.
No burns or broken ends. If upper surface
has non-skid coating, no rot or plywood
separation on underside.
• Side or end brackets: hook-on attachment
not distorted. No cracks in welds. No dents,
kinks, or any signs of abuse.
• Guardrails: straight, with no kinks, dents, or
excessive rust.
• Casters: same size and from same
manufacturer. Wheel rotates well and the
swivel below the stem is working. Brake
mechanism works properly. Wheel tread has
no damage.
• Levelling jacks: no cracks in weld where
levelling jack is attached to the top of the
caster. No thread damage. No curling or
warping of the base plate. Adjusting nut is a
tight t.
• Other equipment: inspect any other
equipment in the frame structure. Damaged
equipment should be tagged and marked as
not t for use. Inform the supervisor so that
others do not use it.
THE PRODUCT OR ASSEMBLY VARIANTS SHOWN IN THESE INSTRUCTIONS FOR ASSEMBLY AND USE MAY BE SUBJECT TO LOCAL
REGULATIONS. THE PRODUCT USER BEARS THE RESPONSIBILITY FOR COMPLIANCE WITH SUCH REGULATIONS, IF THERE IS A CON-
FLICT BETWEEN THIS GUIDELINES AND THE LOCAL REGULATIONS, LOCAL REGULATIONS SHALL SUPERSEDE THESE GUIDELINES.
