FALL FROM HEIGHT

INCIDENT DETAILS:

The worker was given a task to install a handrail on the scaffolding located at 2nd floor of the under construction building structure as it was left exposed after the removal of the cantilever handrail. He was working alone at that time and while installing and fixing the 21 ft long scaffolding tube straddling the midrail of the cuplock scaffold formwork, he lost his balance and fell forward over the leading edge onto the unsupported plywood which gave way causing him to fall to the ground floor slab. He sustained a fracture to the back of his right wrist. In this incident, the worker was still considered as "lucky" as far as the significant height is concerned he had fallen could have led him to more serious injury or even fatal.

Other Causes:
  • Sequence of work was incorrect. The correct sequence shall be like this: The handrail on the 2nd floor should have been installed prior dismantling the cantilever.
  • Lack of supervision.
  • Insufficient and inadequate instruction and information.
LESSONS:
  1. Review the work method of statement, risk assessment and communicate to all supervision with acknowledge signatures.
  2. Planned task observations to be frequently carried out to identify incorrect sequence of work to ensure safety at all times.
  3. Initiate day to day safety hints & tips and communicate it to all supervisors and workers with instructions.
  4. Toolbox talks to be scheduled with emphasis on the responsibility for an individual to secure his harness in a fall risk position.
  5. Conduct training regarding all aspects of the safety harness including inspection and utilization.
IMPORTANT NOTES:
"Competent supervision on all given tasks. Risk of the task to be discussed with the worker prior to the task commencing".
