Worker killed by Toppled Formwork - WSH Bulletin & WSH Council

4 Jun 2010


On the day of the incident, a group of workers was deployed to carry out formwork installation. The formwork was supported by out-riggers and timber props. When a section of the formwork was lifted away, the remaining formwork collapsed and toppled onto a worker. He subsequently died from his injuries.


1. Conduct risk assessment: Prior to the commencement of work, a risk assessment should be carried out to determine the potential hazards and risks that might arise during the installation of formwork. Control measures and safe work procedures must be established to mitigate the risks, and be communicated and implemented to ensure the safety and health of the workers involved.

2. Secure formwork: The Workplace Safety and Health (Construction) Regulations requires that measures to be taken to ensure the stability of any formwork structure or parts of the formwork structure. All formwork components should be properly tied, footed, braced and supported to prevent toppling whether it is during erection or when it is not in use. Where original out-riggers provided by manufacturers as part of its design is used for bracing of formwork, such props or shores shall not be replaced with other forms of support not designed for or provided by the manufacturer.

3. Cordon off work area: Workers who are not directly involved in the formwork installation should be advised to keep away from the vicinity while formwork structures are being erected, or where there are placement of concrete or lifting of formwork sections. Appropriate measures such as the erection of proper barricades and warning signs, and briefing of workers should be carried out prior to the commencement of work. Workers should also stay away from the lifting zone and from any objects that are planned to be lifted.

4. Ensure supervision: A formwork supervisor should be present to oversee the proper erection of the formwork at site. Where an unsafe condition is discovered by the supervisor, the occupier should be notified immediately to rectify the situation.
