Height work-related health checkup and permit shall be in place.
Selection of workers who are going to perform the operations on cradle
Ensure the appropriate planning and assessment of the operation including the selection of a suitable
suspended working platform for the type of the job and the working environment
Carry out the risk assessment for the entire activity considering the man, machine, material used
during the cradle installation.
Ensure relevant documents should be available which to be reviewed by competent person so as to
ensure the design, construction, and assembly of the complete installation, as well as individual
items/components, are in accordance with the manufacturer’s specifications and the Code of Practice
The information and documents should include: - the manufacturer’s instruction and maintenance
manual, the maintenance records, inspection records, test certificates
Machine parts and safety devices that are listed in the operation and maintenance manual, repair log
books, and history of the suspended working platform are in good working order
Ensure the risk assessment carried out and its communicate to entire cradle team
Ensure any cradle movement area should be obstructions free, no lifting equipment should intersect
during cradle operation
Where the suspended working platform is counterbalanced by counterweights, it is important to
ensure that adherence to manufacturer’s guideline to determine the counterweights and they are in
proper and secure position
Wherever parapet wall clamps are used, a horizontal structural member should be arranged to serve
as tie/strut to maintain constant distance between the two outriggers/supports for hanging the

cradle
The erection of a suspended working platform and the alteration of any structure from its original
design should only be carried out under the supervision of a competent person
The third party certification shall be obtained after every alteration, modification or any changes to
the cradle
Contractors should ensure that the structural strength of the parapet is adequate prior to installation
of the suspended platform
Structural engineers’ comments on the installation of suspended working platform should be
obtained whenever necessary
Ensure that no alteration to the electrical or mechanical parts of the Cradle is allowed
Ensure job specific PPE(Personal protective equipment) is available before operation on cradle
Ensure personal fall arrestor system is installed
Ensure every structural member and joint of the working platform should be checked to ensure that it
is free from wear, corrosion, visual cracks, bends or dislocation
Ensure tower crane OCP (operational control procedure) has been followed in case of cradle parts
lifting
Cradle Operation
Selection and arrangement of man & material for operation
Ensure required and job specific PPE is available and workers are competent enough to wear that
Ensure height pass has been conducted before working on platform
Ensure medical test has been carried out for the worker
Ensure that cradle is not being used for material or man transportation purpose
The information and instructions contained in the safe system of work are disseminated to all working
personnel
Ensure necessary training in connection with the subjects are provided to them
Ensure area is properly barricaded and appropriate signage has been provided at ground floor or
landing platform of cradle
Ensure suitable and adequate communication means are provided for the personnel working on the
cradle
Conduct the tool box talk before cradle operation
Ensure that cradle should not overload and all safety devices are in working condition
Wear safety harness with its lanyard attached properly to the independent lifeline or specified
anchorage so provided. The lanyard should never be anchored to any railings or fittings of the
working platform unless they have been specified and tested for the purpose
The lifeline is properly installed and anchored through fall arrestor
Ensure that cradle operation workers have their immediate supervisor or safety personnel contact
numbers for emergency contact
Any defect of the suspended working platform is recorded and reported to the owner or the
maintenance contractor if such defect is out of repair under his control.
Ensure no loose materials stored inside cradle
Ensure all cradle engine gears or other tools are physically fit and its record has been maintained, it
should be maintained by competent personnel
Ensure that cradle is fitted with roof which can arrest any falling objects
The power supply cable or lifting wires/ropes should be properly guided and kept in order to avoid

Cradle Operations
any accidental entanglement.
Every component for fixing or anchoring the suspended working platform such as holding-down bolts,
tie-back ropes/beams, turn-buckles, bracings/ledgers and stiffeners/paddings including roof fixing
should be thoroughly examined to ensure that they are in proper position, securely tightened and
free from cracks, corrosion, excessive wear, dislocation or deformation
The ropes should be in safe working condition and no bolts are loose or have been removed and that
all connections are sound
Ensure all power tools are adequately safety checked before its operation and appropriate HSE
guidelines followed
Ensure safety catching netting system are in place beneath the working location
Cradle dismantling
Ensure cradle dismantling has been carried out by competent personnel
Ensure dismantling workers are aware of the hazards associated with dismantling
Ensure that area is completely cordoned off before dismantling starts
Ensure the dismantling sequence has been followed as per the instruction provided by competent
supervisor and as per the guidelines provided by the manufacturer or supplier
Ensure no unauthorized entry is allowed in the area of dismantling.
Ensure all electrical connections are properly secured and concern team is informed of dismantling
process
Ensure all workers have been informed regarding dismantling
Ensure work relevant signage are in place before dismantling starts

Operational Control Procedures (OCP-17)
Cradle Operations
Reflective Jacket(All PPEs must be in line with Routine Safety inspection for cradle
approved plan or relevant IS standards) Routine safety inspection by safety officers
Earplug/ muff must be used during high noise as well external parties
Control of Significant Environmental Aspects and Significant OHS Hazards
Control of Significant Environmental Aspects:
Environmental Risk- Generation of Noise & Dust emission
Selection of less noisy machines or equipment to be deployed
Ambient noise monitoring/Air quality checks
Sprinkling of water for dust control
Environmental Risk- Consumption of natural resources
Optimize the natural resource consumption by regular monitoring of consumption of electrical energy
and water consumptions.
Optimize the number of trips of logistically and judicially to ensure the lowest consumption.
Ensure all the electrical appliances used at the site are BEE certified and all the equipment is installed
as per the capacity requirement at the site.
Spread the message of conservation of natural resources in the organization through posters,
education through pep talks and competition on environmental issues.
Control of Significant OHS Hazards:
OHS-Risk-Fall of person/material
All persons riding on the cradle shall be equipped with a safety harness which shall be attached to an
independent lifeline at all times.
A competent person shall be appointed to carry out the necessary inspections on the
cradle prior to use, and after any event that could affect the safe operation of the scaffold
The adequate risk assessment shall be conducted for the use of a cradle.
Emergency response should be explained to the operators as per approved onsite emergency plan
The area perpendicular to cradle must be cordoned off to prevent the risk of objects falling down on
any persons
All handheld tools used in the cradle must be properly secured to prevent them from dropping out of
the cradle.
OHS-Risk-Collision with other equipment
A maintenance program must be implemented to ensure proper working condition of the suspended
platform
All operators of the cradle must be adequately trained in the proper use of the cradle
All erectors/operators/users of cradle shall be briefed on the safe work procedures that have been
established.
Always keep safe distance from other equipment’s
During erection, do measure radius for the collision distance with other equipment’s to prevent
collision
Do communicate with another equipment operator for cradle operations
