- Never take chances. If in doubt regarding safety or use of suspended
scaffolds, consult your scaffold supplier or your supervisor.
- Survey the job site for hazards such as exposed
electrical wires, obstruction that could overload or tip the
suspended scaffold when it is raised or lowered, unguarded roof
edges or opening, inadequate or missing tieback anchorages or
the need for overhead protection where exposure to falling objects
exists. Correct these conditions before installing
or using suspended scaffold systems.
- Inspect all equipment before each use.
Never use any equipment that is damaged or defective
in any way. Tag damaged or defective equipment and remove it
from the job site. If it is a rental - return it.
- Always use fall arrest equipment when using
- Erect, use and dismantle suspended scaffold
equipment in accordance with design and/or manufacturer's recommendations.
- Do not erect, dismantle, or alter suspended
scaffold systems unless under the supervision of a qualified
- Do not abuse, misuse, or use suspended scaffold
equipment for purposes which it was not intended.
- Make sure you are trained to safely operate
equipment and to handle emergency situations. (See your Supervisor for this training.)
- Continuously inspect the erected suspended
scaffolds to determine that they are maintained in a safe condition. Report any unsafe condition to your supervisor.
- Windy conditions are potentially hazardous.
Refer to the manufacturer's operating guidelines for limits.
- NEVER OPERATE POWERED PLATFORMS NEAR LIVE
POWER LINES UNLESS PROPER PRECAUTIONS ARE TAKEN.
- Do not work on scaffolds if you feel dizzy,
unsteady or are impaired in any way by alcohol and other drugs,
including prescription medication.
- When rigging suspended scaffolding always
wear fall protection equipment.
- Make sure roof hooks, parapet clamps, outrigger
beams, or other supporting devices, including tiebacks and their
anchorages, are capable of supporting four times the rated load
of the hoist.
- Verify that the building or structure will
support four times the weight of the load you intend to suspend.
- Secure overhead rigging, including counterweights,
from unintentional movement in any direction.
- Make sure counterweights used with outrigger
beams are of a non-flowable material and are fastened to the
- Make sure outrigger beams that do not use
counterweights are installed and secured on the roof structure
with devices specifically designed for that purpose.
- Tie back all transportable rigging devices
with wire rope and hardware that has strength equal to the hoist
- Install tiebacks at right angles to the face
of the building and secure without slack to a structurally sound
portion of the building to prevent movement.
- Rig so that suspension points are directly
above the hoisting machines.
- Secure the platforms to prevent swaying.
Do not tie to window cleaning anchors.
Rope and Hardware Guidelines
- Use only wire rope and attachments as specified
by the hoisting machine manufacturer. Do not use wire rope that is kinked, birdcaged,
corroded, undersized, or in any way damaged.
- Be sure that wire rope is long enough to
reach to the lowest possible landing.
- Clean, lubricate and handle wire rope in
accordance with the wire rope or hoist manufacturer's instructions.
- Coil and uncoil wire rope in accordance with
the wire rope or hoist manufacturer's instructions in order
to avoid kinks and damage.
- Use thimbles at wire rope suspension terminations.
- Where rope clamps are used, they shall be
made with U-bolts on the dead or short end of the rope and the
saddle on the live end.
- Tighten wire rope clamps in accordance with
the clamp manufacturer's instructions.
- Make sure that wire ropes used with traction
hoist have prepared ends in accordance with the manufacturer's
- Inspect wire rope
during each ascent and descent.
Do not expose wire rope to fire,
undue heat, corrosive atmosphere, chemicals, or to passage of electrical currents or to
damage by tools or handling.
- Be sure your power supply conforms to hoist
- Ground all electrical power sources, power
cord connections and protect with circuit breakers.
- Use power cords of proper size that are long
enough for the job.
- Make sure power cord connections are restrained
to prevent their separation.
- Tie off power cords to the suspended scaffold
to prevent them from falling.
- Protect power cords from sharp edges.
Arrest Equipment Guidelines
- Each person on a suspended powered scaffold
must be attached to a fall arrest system (rope grab & rope
lifeline) at all times.
- Make sure each rope lifeline is fastened
to a separate anchorage point.
- Protect rope lifelines at sharp corners to
- Rig fall arrest systems to prevent free fall
in excess of four feet.
- Suspend rope lifelines freely, without contact
with structural members or building facade.
- Be sure rope grabs are installed on the rope
lifelines in the proper direction above your head and in accordance
with the manufacturer's recommendations.
- Use full body harnesses that are properly
sized and fitted.
- Attach rope grabs
to the D-ring at the center of the back.
