|Stakeholders such as occupiers, employers, principals and contractors in control of similar workplaces and work activities are advised to consider the following risk control measures to prevent similar accidents:|
|Safe work method|
• In accordance to Section 9.6 of SS 580: 2012 – Code of Practice for Formwork,
all system formwork suppliers shall provide documented instructions and training
on erection, use, transfer, alteration and dismantling of the formwork system.
• Prior to formwork structure erection, ensure that the structures used are
adequately designed for its intended purpose.
• Check that formwork structure components used are in good condition and
replacement parts (if any) are approved for use by the manufacturer.
• Ensure that the erection, use, transfer, alteration and dismantling of all
formwork structures are carried out in accordance to the manufacturer’s
|Address risk of falling object(s)|
• Properly secure all loose formwork structure components to prevent
accidental dislodgement during erection, use, transfer, alteration and dismantling
of the formwork system.
• Should ground or overhead conditions not permit the safe shifting (transfer) of
the formwork structure, it may be safer to dismantle the formwork structure for
shifting and re-erection at its new desired location.
|Worker training and supervision|
• Employers must ensure that all personnel (including formwork supervisors and
workers) involved in formwork activities have received adequate safety and
health training with regards to the hazards associated with formwork structures.
• For formwork structures supplied by a manufacturer, ensure that all relevant
personnel have attended the familiarisation training and/or briefing provided
by the manufacturer.
• Ensure that adequate on-site supervision is provided for all formwork-related
activities. This is to ensure that the safe work method is adhered to and that the
work is carried out safely.
• Supervisors can help to ensure that all formwork structures and related work
activities comply with the requirements stated in Part IX of the Workplace Safety
and Health (Construction) Regulations and SS580: 2012 – Code of Practice
Conduct a thorough Risk Assessment (RA) for all work activities to manage any foreseeable risk that may arise during formwork-related works. The RA should cover but not limited to the following areas:
|• Presence of loose formwork structure components that may fall on workers|
• Uneven or sloping ground that may prevent the safe shifting of formwork structure
• Overhead structures (e.g. beams) that the formwork structure may collide with
• Stability of the formwork structure during shifting
• Adequacy of supervision during formwork activities
