Failure to install all required components such as
base Plates, connections, and braces

Failure to use all of the proper scaffold components is a

serious safety problem. Workers are more likely to cut cor-
ners when scaffolds are only a few frames in height. All

too frequently they fail to install base plates, braces, prop-
er securing devices such as “banana” clips or “pig tails” at

the pins of frame scaffolds, and adequate tie-ins. Those
erecting the scaffold must have all the necessary compo-
nents, and must use them to ensure that the scaffold is

safe. Furthermore, workers should install these parts as
the scaffold erection progresses. No Toe board

Moving rolling scaffolds in the vicinity of overhead Electrical wires

Scaffolds seldom make contact with overhead electrical lines,
but when it does happen it almost always results in a fatality.

Failure to maintain safe distances from overhead powerlines
while moving scaffolds is a major problem. Before attempting to

move rolling scaffolds in outdoor open areas, check the route
carefully to ensure that no overhead wires are in the immediate
vicinity.

Partial dismantling may be necessary in some situations to en-
sure that the scaffold will make the required safe clearances

Unsafe movement of scaffold from overhead powerlines. Hoisting scaffold material by forklift
or other mechanical means requires careful planning and should be avoided in the vicinity of
powerlines. Transporting already-erected scaffolds by forklift, particularly in residential construc-

tion, has been the cause of many electrical contacts — this is a dangerous practice. Workers
handling materials or equipment while working on the platform must also take care to avoid elec-

trical contact.

Minimum distance from powerline is listed below:-

Voltage rating of powerline Minimum distance
750 volts to 150000 volts 3 meters (10 feet)
150001 volts to 250000 volts 4.5 meters (15 feet)
Over 250001 volts 6 meters (20 feet)

Moving rolling scaffolds with workers on the platform.

Moving rolling scaffolds with workers on the platform can be dangerous. Where it is impractical
