Factory Notification or Registration requirements

If your workplace is defined as a factory under the WSH Act, depending on the risk level of the activities performed, you must either notify or register the premises with MOM. You don’t need to register or notify a non-factory workplace.

Notification or Registration

All factories, in accordance with the Workplace Safety and Health (WSH) Act, must either notify or register their activities with us before starting operations.

If your factory engages in high-risk activities, you will have to apply for a Certificate of Registration (CR).

If your factory engages in low-risk activities, you will have to submit a one-time Notification declaring your activities.

You can use the self-assessment tool to find out if your factory requires a Notification or Certification of Registration.

Non-factory workplaces are not required to be registered or notified with MOM.
