STUPID SET-UPS
STUPID SET-UPS
 The plank is
supported by an
extension
ladder, a closed
step ladder and
a straight
ladder.
 The guardrails
are not
acceptable.
 There is no
stability
 Scaffold are
resting on CHB,
which are
unstable

SCAFFOLD REQUIREMENTS
SCAFFOLD REQUIREMENTS
 Be on a firm foundation with base plates
 Be plumb, square and adequately braced
 Have a fully planked work deck
 Have guardrails over 10 feet
 Be tied in over 4 Vert./1 Horiz. high
 Have an adequate means of access

16. SCAFFOLD CAPACITY
SCAFFOLD CAPACITY
 Must be able support
its own weight and 4
times the maximum
intended load.
 Scaffolds must be
designed by a
qualified person.
 They must and built
and loaded within
design. TIP! Scaffolds can be overloaded by
removing the braces – which cause the
weight to be unevenly supported by fewer
members. Do not remove supports, even
if they’re in the way.

COMPETENT PERSONS
COMPETENT PERSONS
 All scaffolds must be
erected, moved,
dismantled or altered
only under the
supervision of a
competent person

18. 18
SCAFFOLD FOUNDATIONS
SCAFFOLD FOUNDATIONS
 Scaffolds must have
base plates, even when
setting on a concrete
floor.
 Also, the lack of a base
plate could damage the
scaffold leg.

19. 19
 Scaffold legs must be
set on base plates and
adequate mudsills.
 There is no base plate
and the scrap plywood
is not adequate.
 The scaffold frame
could penetrate the
plywood.

NEVER ON MASONRY!
NEVER ON MASONRY!
 Scaffolds should never
be set on bricks,
masonry blocks, etc.
 These are not structural
elements and could
crush under the scaffold
load.
