CODE OF SAFE PRACTICES
FOR
FRAME SCAFFOLDS, SYSTEM SCAFFOLDS,
TUBE AND CLAMP SCAFFOLDS & ROLLING SCAFFOLDS
DEVELOPED FOR INDUSTRY BY
SCAFFOLD INDUSTRY ASSOCIATION, INC.
It shall be the responsibility of all users
to read and comply with
the following common sense guidelines which
are designed to promote
safety in the erecting, dismantling and use
of Scaffolds. These
guidelines do not purport to be all-inclusive not
to supplant or
replace other additional safety and precautionary measures
to cover
usual or unusual conditions. If these guidelines in any way
conflict
with any state, local, federal or other government statute
or
regulation, said statute or regulation should supersede these guidelines
and it shall be the responsibility of each user to comply therewith.
-
GENERAL GUIDELINES
-
POST THESE SCAFFOLDING SAFETY GUIDELINES in a
conspicuous
place and be sure that all persons who erect, dismantle
or use
scaffolding are aware of them.
-
FOLLOW ALL STATE, LOCAL, AND FEDERAL CODES, ORDINANCES
AND
REGULATIONS pertaining to scaffolding.
-
SURVEY THE JOB SITE. A survey shall be made of
the job site
for hazards, such as untamped earth fills, ditches,
debris,
high tension wires, unguarded openings, and other hazardous
conditions created by other trades. These conditions should be
avoided as noted in the following sections.
-
INSPECT ALL EQUIPMENT BEFORE USING. Never use
any equipment
that is damaged or defective in any way. Remove
it from the
job site.
-
SCAFFOLDS MUST BE ERECTED IN ACCORDANCE WITH
DESIGN AND/OR
MANUFACTURERS’ RECOMMENDATIONS.
-
DO NOT ERECT, DISMANTLY OR ALTER A SCAFFOLD unless
under the
supervision of a qualified person.
-
DO NOT ABUSE OR MISUSE THE SCAFFOLD EQUIPMENT.
-
ERECTED SCAFFOLDS SHOULD BE CONTINUALLY INSPECTED
by users to
be sure that they are maintained in safe condition.
Report any
unsafe condition to your supervisor.
-
NEVER TAKE CHANCES! IF IN DOUBT REGARDING THE
SAFETY OR USE OF
THE SCAFFOLD, CONSULT YOUR SCAFFOLD SUPPLIER.
-
NEVER USE EQUIPMENT FOR PURPOSES OR IN WAYS FOR
WHICH IT WAS
NOT INTENDED.
-
DO NOT WORK ON SCAFFOLDS if your physical
condition is
such that you feel dizzy or unsteady in any way.
-
GUIDELINES FOR ERECTION AND USE OF SCAFFOLDS
-
SCAFFOLD BASE MUST BE SET ON AN ADEQUATE SILL
OR PAD to
prevent slipping or sinking and fixed thereto where
required.
Any part of a building structure used to support the
scaffold
shall be capable of supporting the maximum intended load
to be
applied.
-
USE ADJUSTING SCREWS or other approved methods
instead of
blocking to adjust to uneven grade conditions.
-
BRACING, LEVELING, & PLUMING OF FRAME SCAFFOLDS—
-
Plumb and level all scaffolds
as the erection proceeds. Do
not force frames or braces to
fit – level the scaffold
until proper fit can easily be made.
-
Each frame or panel shall be
braced by horizontal bracing,
cross bracing, diagonal bracing
or any combination thereof
for securing vertical members together
laterally. All
brace connections shall be made secure, in
accordance with
the manufacturer’s recommended procedures.
-
BRACING, LEVELING, & PLUMING
OF TUBE & CLAMP AND
SYSTEM SCAFFOLDS –
-
POST SHALL BE ERECTED PLUMB
in all directions, with the
first level of runners and bearers
positioned as close to
the base as feasible. The distance
between bearers and
runners shall not exceed manufacturer’s
recommended
procedures.
-
PLUMB, LEVEL AND TIE all scaffolds
as erection proceeds.
-
FASTEN ALL COUPLERS AND/OR
CONNNECTIONS securely before
assemble of next level.
-
VERTICAL AND/OR HORIZONTAL
DIAGONAL BRACING MUST BE
ISNTALLED according to manufacturer’s
recommendations.
-
TIE CONTINUOUS (RUNNING) SCAFFOLDS
TO THE WALL OR STRUCTURE at
each end and at least every 30 feet
of length when scaffold
height exceeds the maximum allowable free
standing dimension.
Begin ties or stabilizers when the
scaffold height exceeds that
dimension, and repeat at vertical intervals
not greater than 26
feet. The top anchor shall be placed no lower
than four (4)
times the base dimension from the top of the completed
scaffold.
Anchors must prevent scaffold from tipping into or away
from
wall or structure. Stabilize circular or irregular scaffolds
in
such a manner that completed scaffold is secure and restrained
from tipping.
When scaffolds are partially or fully
enclosed or subjected to
overturning loads, specific precautions
shall be taken to insure
the frequency and accuracy of ties to the
wall and structure.
Due to increased loads resulting from wind or
overturning loads
the scaffolding component to which ties are subjected
shall be
checked for additional loads.
-
WHEN FREE STANDING SCAFFOLD TOWERS
exceed four (4) times their
minimum base dimension vertically,
they must be restrained
from tipping. (CAL/OSHA and some government
agencies require
stricter ratio of 3 to 1)
-
DO NOT ERECT SCAFFOLDS NEAR ELECTRICAL
POWER LINES UNLESS
PROPER PRECAUTIONS ARE TAKEN. Consult the power
service
company for advice.
-
A MEANS OF ACCESS TO ALL PLATFORMS
SHALL BE PROVIDED.
-
DO NOT USE ladders or makeshift
devices on top of scaffolds to
increase the height.
-
PROVIDE GUARDRAILS AND MID-RAILS
AT EACH WORKING PLATFORM
LEVEL where open sides and ends exist,
and toeboards where
required by code.
-
BRACKETS AND CANTILEVERED PLATFORMS
–
-
Brackets for SYSTEM SCAFFOLDS
shall be installed and used
in accordance with manufacturer’s
recommendations.
-
Brackets for FRAME SCAFFOLDS
shall be seated correctly
with side bracket parallel to the
frames and end brackets
at 90 degrees to the frames. Brackets
shall not be bent or
twisted from normal position. Brackets
(except mobile
brackets designed to carry materials) are to
be used as
work platforms only and shall not be used for storage
of
material or equipment.
-
Cantilevered platforms shall
be designed, installed and
used in accordance with manufacturer’s
recommendations.
-
ALL SCAFFOLDING COMPONENTS shall
be installed and used in
accordance with the manufacturer’s recommended
procedure.
Components shall not be altered in the field. Scaffold
frames
and their components manufactured by different companies
shall
not be intermixed, unless the component parts readily fit
together and the resulting scaffold’s structural integrity is
maintained by the user.
-
PLANKING –
-
Working platforms shall cover
scaffold bearer as
completely as possible. Only scaffold grade
wood planking,
or fabricated planking and decking meeting
scaffold use
requirements shall be used
-
Check each plank prior to use
to be sure plank is not
warped, damaged, or otherwise unsafe.
-
Planking shall have at least
12" overlap and extend
6" beyond center of support,
or be cleated or
restrained at both ends to prevent sliding
off supports.
-
Solid sawn lumber, LVL (laminated
veneer lumber) or
fabricated scaffold planks and platforms
(unless cleated
or restrained) shall extend over their end
supports not
less then 6" nor more than 18". This
overhang
should not be used as a work platform.
-
FOR "PUTLOGS" AND "TRUSSES"
THE FOLLOWING
ADDITIONAL GUIDELINES APPLY:
-
Do not cantilever or extend
putlogs/trusses as side
brackets without thorough consideration
for loads to be
applied.
-
Putlogs/trusses should be extended
at least 6" beyond
point of support.
-
Place recommended bracing between
putlogs/trusses when the
span of putlog/truss is more than
12 feet.
-
FOR ROLLING SCAFFOLDS THE FOLLOWING
ADDITIONAL GUIDELINES
APPLY:
-
RIDING A ROLLING SCAFFOLD IS
VERY HAZARDOUS. The Scaffold
Industry Association does not
recommend nor encourage this
practice. However, if you choose
to do so, be sure to
follow all state, federal or other governmental
guidelines.
-
Casters with plain stems shall
be attached to the panel or
adjustments screw by pins or other
suitable means.
-
No more than 12 inches of the
screw jack shall extend
between the bottom of the adjusting
nut and the top of the
caster.
-
Wheels or casters shall be
provided with a locking means
to prevent caster rotation and
scaffold movement and kept
locked.
-
Joints shall be restrained
from separation.
-
Use horizontal diagonal bracing
near the bottom and at 20
foot intervals measured from the
rolling surface.
-
Do not use brackets or other
platform extensions without
compensating for the overturning
effect.
-
The platform height of a Rolling
Scaffold must not exceed
four (4) times the smallest base
dimension (CAL/OSHA and
some Government agencies require a
stricter ratio of 3 to
1).
-
Cleat or secure all plank.
-
Secure or remove all materials
and equipment from platform
before moving.
-
Do not attempt to move a rolling
scaffold without
sufficient help – watch out for holes in
floor and
overhead obstructions – stabilize against tipping.
-
SAFE USE OF SCAFFOLD –
-
Prior to use, inspect scaffold
to insure it has not been
altered and is in safe working condition.
-
Erected scaffolds and platforms
should be inspected
continuously by those using them.
-
Exercise caution when entering
or leaving a work platform.
-
Do not overload scaffold. Follow
manufacturer’s safe
working load recommendations.
-
Do not jump onto planks or
platforms.
-
Do not use ladders or makeshift
devices on top of working
platforms to increase height or
provide access from above.
-
Climb in access areas only
and USE BOTH HANDS
-
WHEN DISMANTLING SCAFFOLDING THE
FOLLOWING ADDITIONAL GUIDELINES
APPLY:
-
Check to assure scaffolding has not been structurally
altered
in a way which would make it unsafe and, if it has, reconstruct
where necessary before commencing with dismantling procedures.
This includes all scaffold ties.
-
Visually inspect plank prior to dismantling to
be sure they
are safe.
-
Consideration must be given as to the effect
removal of a
component will have on the rest of the scaffold prior
to that
component’s removal.
-
Do not accumulate excess components or equipment
on the level
being dismantled.
-
Do not remove ties until scaffold above has been
removed
(dismantled).
-
Lower dismantled components in an orderly manner.
Do not throw
off of scaffold.
-
Dismantled equipment should be stockpiled in
an orderly
manner.
-
FOLLOW ERECTION PROCEDURES AND USE MANUALS.
These safety guidelines (Code of Safe Practice)
set forth common
sense procedures for safely erecting, dismantling and
using
scaffolding equipment. However, equipment and scaffolding systems
differ, and accordingly, reference must always be made to the instructions
and procedures of the supplier and/or manufacturer of the equipment.
Since field conditions vary and are
beyond the control of the
Scaffold Industry Association, safe and proper
use of scaffolding is
the sole responsibility of the user.
