Materials to be used in erecting scaffolding should be in good
condition;

Steel items should be free from rust; and

Mandatory inspection should be conducted by experienced and
competent person to all materials before use.

b. Foundation

til.

Vi.

Scaffold shall be capable of supporting without failure at least 4
times the maximum intended load;

i. Timber sills at least 23 cm (9.1 in.) wide by 3.8 cm (1.5 in.) thick

will be required to spread the load. A sili shall extend under at
least two post;

Where scaffolding is erected on a solid bearing such as rock or
concrete, small timber pads may be used in place of sills and
nailed to prevent the base plates sliding off:

if used to compensate variations in ground levels, the screw
jacks shail not be adjusted more than two-thirds of the total
length of the thread;

Scaffolds shall be anchored or secured to permanent or rigid
structures. In the absence of permaneni structures, guys and
sway bracing and/or outrigger shall be used; and

The foot of any standards or upright should be adequately
founded on a suitable base plate in order to prevent slipping or
sinking.

c. Posts

Posts shall be pitched on 6 inches (15 cm) by 6 inches (15 cm)
steel and at least 0.25 inch (0.64 cm) thick. All post shall be
vertical; and

The inner row posts shall be placed as closed as possible to the
face of the building structure. The outer row shall be positioned
depending on the load requirements of the scaffold.

d. Runners

Runners shall be securely fixed to post with standard couplers
and shall be horizontal; and

ii.

Runners shall be vertically spaced no more than 6.5 feet (2.0
meters) to give adequate headroom along the platform.

i.

Bearers should be installed between post and securely fixed to
the post with standard couplers; and

Board bearers shall be installed between bearers to
accommodate differences in planks length.

Bracing

Longitudinal diagonal bracing shail be installed at approximately
45° angle from near the base of the first outer post upward to
the extreme top of the scaffold.

All supported scaffolds except tower and mobile shall be
securely tied to a building or structure throughout their length
and height to prevent movement of the scaffold;

Ties should be spaced every other lift and every 19.6 feet (6
meters) along the face of the scaffold;

Ties should be fixed with load bearing couplers, as close to the
node point as possible;

Any structural features of the buildings ¢.g. pillars, columns,
lintels, rebates, etc. should be taken full advantage to provide
additional strength and stability to the tie:

Make sure that the building is strong enough to support the tie
and the load imposed on it by the scaffold; and

For any reason, ties should not be removed until the overall
stability of the scaffold has been confirmed.

Platform Units

All platform units shail be closed planked for the full width of the
scaffold structure;

Pianks shall be extend over their end supports by not less than
6 inches (15 cm) and not more than 12 inches (30.5 cm);

Planks shall be secured in position to prevent displacement by
strong winds;

iv. Mid rails must be installed halfway between the top rail and
platform and can withstand force of 150 Ibs.; and
v. Toe boards shall not be less than 4 inches (10 cm.) in height by
1 inch (2.5 cm) thick.
i. Access

Access to a working platform is best achieved by providing a
separate ladder tower or a cantilevered access platform so as
not to obstruct the working platform and to minimize the risk of
persons falling through gaps in the guardrail system or platform
units. Access should be provided to working platforms; and

Working platform shall be provided per level during erection.
This working platform shall not be removed unless the
succeeding level is installed.

j. Workmanship

i.

Scaffolding shall be erected, altered and dismantled by
experienced men working under the direction of a competent
supervisor; and

Scaffoids of more than 19.6 feet (6 meters) in height shall be
designed by a structural engineer and shall be erected, installed
and dismantled by TESDA certified erectors.

k. Inspection

All scaffolds shall be inspected by a competent supervisor,
safety officers, and/or civil engineers before it is used and after
adjustments, modifications, adverse weather conditions, etc., to
measure that is safe:

ii Green tags shall be hanged at each scaffolds access that
have been inspected and are safe for use;

iii Yellow tags shall be placed whenever special
requirements for safe use are required. Situation requiring
yellow tags may include whenever scaffoid has been
modified to meet work requirements, and as a result could
present a hazard to the user. Situation requiring Yellow
tags shall be closely supervised; and

iii Red "DANGER - UNSAFE FOR USE” tags shail be used
during erection and dismantling when the scaffold is left
unattended. Red tag shall be used when all green or yellow
tags has been removed or during erection of scaffolds.
