Persons in control of similar workplaces and work activities such as occupiers, employers and principals are advised to consider the following risk control measures to prevent similar accidents:
|Safe lifting operation|
• Establish a lifting plan to ensure that the lifting operation can be carried out
safely. Key information in the lifting plan should include information on the load
to be lifted and its weight, the rigging method to be used as well as a sketch of
the zone of operation with the initial and final location of the load and its path
• Prior to starting the lifting work, checks for obstacle along the path of travel
that can hinder the safe manoeuvring of the load or result in possible
entrapment points must be done. This can be achieved by conducting a
workplace inspection prior to work commencement.
• Cordon off the zone of operation to prevent persons who are not involved in
the lifting operation from entering the zone while the lifting operation is in
progress. The lifting team should maintain a safe distance from the suspended
load while it is being lifted. No one should be allowed to be under the
suspended load at any time.
• Ensure lifting and lowering of loads are done safely within stipulated speed limit.
• Additional safety considerations include the use of taglines for better control
of the movement of the suspended load, special provisions (e.g. by installing
remote cameras) to ensure the crane operator’s clear line of sight of the lifting
operation, and the placement of warning signs to alert persons in the vicinity
of the lifting activity and to stay clear of the zone of operation.
|Lifting team competency|
• Ensure all members of the lifting team are competent in their respective
roles (i.e. lifting supervisor, crane operator, signalman, rigger) and have
successfully completed the relevant safety and health training (e.g. Supervise
Safe Lifting Operations course for lifting supervisors).
• Crane operator must be trained to operate the specific make and model of the
lifting equipment used on site.
• Ensure the presence of an on-site lifting supervisor to oversee and co-ordinate all
lifting activities in accordance with the lifting plan.
• Supervisors are to conduct toolbox meeting prior to work commencement so that
all workers are aware of on-site hazards and the risk control measures that are
• Always confirm that each member of the lifting team is in a safe work position
before and during the lifting operation.
Conduct a thorough Risk Assessment (RA) for all work activities to control any foreseeable risk that may arise when carrying out lifting operations. The RA should cover, but not limited to, the following areas:
|• Effectiveness of Permit-To-Work (PTW) system for lifting activities and its|
• Effectiveness of communication between lifting team members before and during
• Personnel movement in and around the lifting zone.
• Emergency response plan including site-specific rescue plan and medical evacuation
in the event of accident.
