Certain workplaces are required to implement a safety and health management system (SHMS), including risk assessments and risk management.
What is a safety and health management system
A safety and health management system (SHMS) is a systematic process for managing workplace safety and health. The system features:
- Setting goals
- Planning
- Measuring performance
- Managing commitments and direction
Workplaces must also audit or review their SHMS regularly to ensure continual improvements.
Workplaces requiring audits
You must appoint a MOM-approved workplace safety and health auditor listed in the SAC AO schedule of an SAC-accredited WSH Auditing Organisation to regularly audit your SHMS if your workplace is one of the following:
|
Type of workplace
|
How often to audit
|
|
Any worksite with a contract sum of $30 million or more
|
At least once every 6 months

- Audit is done by persons who are listed in the SAC AO Schedule and registered through WSH eServices.
- Audit covers all the Workplace Safety and Health Requirements for Marine Industries published by WSH Council.
Metalworking industry

- Audit is done by persons who are listed in the SAC AO Schedule and registered through WSH eServices.

Oil refinery or petrochemical plant / semiconductor wafer fabrication plant / chemical manufacturing plant / pharmaceutical plant / bulk storage terminal
Certification based on SS506 Part 3 or SS 651 is accepted as meeting the audit criteria of these industrial sectors when:
- Audit is done by an SAC-accredited Certification Body (CB) that is also an SAC-accredited Auditing Organisation (AO).
- Audit is done by persons who are listed in the SAC AO Schedule and registered through WSH eServices.
Workplaces requiring SHMS internal review
Your workplace needs to conduct a periodic internal reviews on the SHMS if the following applies:
| Type of workplace |
How often to review |
| Any worksite with a contract sum of less than $30 million |
At least once every 6 months |
| Any shipyard employing fewer than 200 persons |
At least once every 12 months |
What is an SHMS internal review
An internal review is similar to an external audit.
You should appoint an SAC-accredited WSH auditing organisation or MOM-approved WSH auditor to conduct internal reviews of your SHMS.
Alternatively, you can assign a staff who has minimally passed an established audit course to conduct the internal reviews. Such audit course can be the ISO 45001 internal audit training course.
Your internal review must:
- Produce the same outcomes of a developed SHMS.
- Suit to your work activities.
- Effectively implemented at your workplace.
The internal review report must be:
- Kept as record.
- Produced upon MOM Inspector’s requests.
