Try these sample questions to test your WSQ WSH Officer (SDWSH) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A newly appointed WSH Officer is asked which single statute imposes the overarching general duties on occupiers, employers, principals and employees in Singapore workplaces. Which is correct?

A.Employment Act 1968

B.Workplace Safety and Health Act

C.Factories Act (now repealed)

D.Building Control Act

Explanation: The Workplace Safety and Health Act is the primary statute setting out general duties for stakeholders such as occupiers, employers, principals, self-employed persons and employees. All subsidiary regulations (Risk Management, Construction, Noise, etc.) are made under the WSH Act.

2A factory ordinarily employs 60 persons. Under the WSH (Workplace Safety and Health Committees) Regulations, what must the employer do?

A.Nothing, because a committee is only needed at 100 or more persons

B.Form a WSH Committee, because the factory has 50 or more persons at work

C.Appoint a registered WSH Auditor

D.Register the factory as a major hazard installation

Explanation: The WSH (Workplace Safety and Health Committees) Regulations apply to every factory in which 50 or more persons are ordinarily at work, so a factory with 60 persons must form a WSH Committee. The committee must meet regularly and keep minutes.

3A workplace employs 250 persons. Applying the WSH (First-Aid) Regulations first-aider ratio, what is the minimum number of appointed first-aiders required?

A.1

B.3

C.10

D.25

Explanation: First-aiders must be appointed where more than 25 persons are employed, at a ratio of one first-aider for every 100 persons or part thereof. For 250 persons that is 3 first-aiders (100, 200, and the remaining 50 each needing coverage).

4A construction worksite has a contract sum of S$15 million. Which appointment does the WSH (Workplace Safety and Health Officers) Regulations require?

A.No registered WSH Officer is required below S$30 million

B.A registered WSH Officer must be appointed

C.Only a Safety Coordinator is required

D.A Professional Engineer must be appointed as the officer

Explanation: The Second Schedule of the WSHO Regulations requires a registered WSH Officer for worksites carrying out building operations or engineering construction of a contract sum of S$10 million or more. At S$15 million, a registered WSHO is mandatory.

5A non-garment manufacturing factory employs 120 persons. Which statement about appointing a WSH Officer is correct?

A.A WSHO is required because 100 or more persons are employed

B.A WSHO is only required for shipyards and petroleum factories

C.No WSHO is required for factories under 200 persons

D.A WSHO is required only if a fatality has occurred

Explanation: The Second Schedule of the WSHO Regulations requires a registered WSH Officer in factories where 100 or more persons are employed (garment-manufacturing factories are the stated exception). A 120-person factory therefore needs a WSHO.

6Under the WSH (First-Aid) Regulations, at what workplace headcount must a first-aid room be provided and maintained?

A.More than 25 persons at work

B.More than 100 persons at work

C.More than 500 persons at work

D.More than 1,000 persons at work

Explanation: A first-aid room of an approved standard must be provided where there are more than 500 persons at work, unless the Commissioner permits otherwise. Below that, appropriate first-aid boxes and appointed first-aiders are the baseline requirement.

7Under the WSH (Noise) Regulations, the permissible exposure limit for noise is commonly summarised as an equivalent sound pressure level of:

A.80 dB(A) over an 8-hour work day

B.85 dB(A) over an 8-hour work day

C.90 dB(A) over an 8-hour work day

D.95 dB(A) over an 8-hour work day

Explanation: The Noise Regulations deem a person exposed to excessive noise when unprotected exposure exceeds an equivalent sound pressure level of 85 dB(A) over an 8-hour work day (or the levels in the First Schedule). This is the key figure driving hearing conservation.

8Besides the 85 dB(A) time-weighted limit, the WSH (Noise) Regulations also deem a worker exposed to excessive noise if the peak sound pressure level exceeds:

A.115 dB(C)

B.125 dB(C)

C.140 dB(C)

D.160 dB(C)

Explanation: The Noise Regulations set a peak sound pressure level limit of 140 dB(C); exposure above this peak (when unprotected) counts as excessive noise regardless of duration. This protects against impulsive noise such as impacts and blasts.

9A factory manager asks the WSHO when a statutory noise monitoring report must be arranged. Under the Noise Regulations, monitoring is required at least once every three years where:

A.Any single worker uses a power tool

B.10 or more persons are likely to be exposed to excessive noise

C.The workplace has more than 500 employees

D.The factory processes petroleum products

Explanation: The Noise Regulations require noise monitoring at least once every three years where 10 or more persons are, or are likely to be, exposed to excessive noise. The report identifies who is over-exposed and drives control measures and hearing conservation.

10Before workers enter a sewer chamber, the WSH (Confined Spaces) Regulations require that entry is authorised by an entry permit approved by the:

A.Confined space attendant

B.Authorised manager

C.First-aider on standby

D.Any worker holding a confined space entry certificate

Explanation: Under the Confined Spaces Regulations, an entry permit must be approved by an authorised manager before persons enter a confined space. A confined space safety assessor evaluates the space and an attendant is posted, but permit approval rests with the authorised manager.

WSQ WSH Officer (SDWSH) Study Tips from Top Performers

1Learn which regulation applies to a given scenario rather than memorising maximum penalties — the CAPR explicitly favours application questions (e.g. 'which section applies?') over penalty trivia.

2Memorise the key thresholds: WSH Committee at 50+ persons, WSHO at construction contract sum S$10 million or 100+ persons in a factory, first-aiders where more than 25 persons (1 per 100), first-aid room above 500 persons, and noise PEL 85 dB(A) over 8 hours with a 140 dB(C) peak.

3Master incident reporting triggers: since 1 September 2020, any work-related medical leave or light duties, or hospitalisation, is reportable within 10 days (the old 'more than 3 days MC' rule is obsolete), plus immediate notification for deaths and dangerous occurrences, and occupational diseases within 10 days of diagnosis via iReport.

4Know the high-risk construction PTW list from the WSH (Construction) Regulations — demolition, excavation/trenching in a tunnel or hole exceeding 1.5 m, tower/mobile/crawler crane lifting, piling and tunnelling — plus confined space and hot-work permits.

5For WSH management systems, connect SS 679's 14 elements and ISO 45001's clause structure to the PDCA cycle, and distinguish a periodic internal review from a statutory audit by an accredited auditor.
