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
   of travel.
• 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.
Work supervision
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
   in place.
• Always confirm that each member of the lifting team is in a safe work position
   before and during the lifting operation.

Risk Assessment

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
   on-site implementation.
• Effectiveness of communication between lifting team members before and during
   lifting operations.
• Personnel movement in and around the lifting zone.
• Emergency response plan including site-specific rescue plan and medical evacuation
   in the event of accident.
