WSH Audit

Certain workplaces must audit their SHMS periodically to ensure that the system remains robust.

As an employer, you must appoint an SAC-accredited WSH Auditing Organisation or MOM-approved WSH auditor to audit your SHMS if your workplace is one of the following:

Type of Workplace

Frequency of Audit

Any worksite with a contract sum of $30 million or more

At least once every 6 months

Any shipyard employing 200 or more people

At least once every 12 months

Any factory engaged in manufacturing fabricated metal products, machinery or equipment, and which employs 100 or more people

Any factory that processes or manufactures petroleum, petroleum products, petrochemicals or petrochemical products

At least once every 24 months

Any premises that store toxic or flammable liquids at a storage capacity of 5,000 or more cubic metres

Any factory manufacturing fluorine, chlorine, hydrogen fluoride, carbon monoxide and synthetic polymers

Any factory manufacturing pharmaceutical products or their intermediates

Any factory manufacturing semiconductor wafers

 

Internal Review

If your workplace belongs to one of the following, you will need to conduct a periodic internal review on the SHMS:

Type of Workplace

Frequency of 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

Like a WSH audit, an internal review of your SHMS should be conducted by an SAC-accredited WSH Auditing Organisation or MOM-approved WSH auditor. Alternatively, you can assign a staff who has minimally passed an established audit course to conduct the internal review.
