Quick Summary
You appoint a WSH Officer or a WSH Coordinator in writing, as the occupier, and only after checking that the person meets the rules for that role. The two roles are appointed under different regulations and carry different checks. Once the person is in the role, the regulations give them duties and powers, and your job is to make those usable.
Our guide to the difference between the two roles explains which one a workplace needs. This post starts where that one stops. It covers how the appointment is made, what you must be satisfied of first, what the person can then do, and what keeps the appointment valid.
In short:
- The occupier makes the appointment. For a WSH Officer, it must be in writing.
- A WSH Officer is a person MOM has approved. A WSH Coordinator is a person the occupier has checked: a training course, competence, and two years of relevant experience.
- Both roles assist and recommend. The regulations give them real powers to enter, inspect, and ask for records.
- Neither appointment is "set and forget". An officer's approval expires, and MOM expects coordinators to take refresher training every two years.
Which role does your workplace need?
It depends on the type of workplace and, for construction, the contract sum. We cover this in full in our earlier guide, so here is only the short version, taken from the regulations themselves.
A workplace must have a WSH Officer if it is in one of four groups listed in the Second Schedule of the WSH (Workplace Safety and Health Officers) Regulations. They include shipyards, petroleum-processing factories, factories carrying out building or engineering construction work with a contract sum of $10 million or more, and other factories with 100 or more people employed (garment factories are excluded).
A WSH Coordinator is a separate appointment. Under the WSH (Construction) Regulations 2007, one must be appointed "in respect of every worksite where the contract sum of the building operation or works of engineering construction carried out therein is less than $10 million".
Two cautions. The two sets of regulations word their scope differently: the officer rules speak of "factories", the coordinator rules of "work sites". If your site sits near the line, ask MOM or whoever owns compliance in your company. And these figures are those shown on Singapore Statutes Online on 22 October 2026. Check the current text before you act on them.
Who makes the appointment?
The occupier of the workplace does, for both roles. The officer rule says the officer "shall be appointed by the occupier of a workplace". The coordinator rule says every coordinator "shall be appointed by the occupier of every worksite" covered.
For a WSH Officer, the appointment must also be in writing. Regulation 8(1) says a workplace in the Second Schedule "shall have appointed in writing" an officer. The coordinator rule, in the text we read, does not say "in writing". Writing it down is still sensible, because it is how you show who was appointed, when, and for which site.
Failing to make a required appointment, without reasonable excuse, is an offence for the occupier under both sets of regulations. We have not reproduced the penalties here. They are set out in the regulations.
What must be true of the person before you appoint them?
For an officer, MOM has to have approved them. For a coordinator, you have to be satisfied of three things.
WSH Officer. An officer holds a certificate of approval from MOM's Commissioner for Workplace Safety and Health. The approval "shall be valid for a period of 2 years" and is "not transferable". The Commissioner "shall keep an up-to-date register of all persons approved" (regulation 6). MOM's own pages set out who can apply, and how an employer can check a card against MOM's published list. We explain both in our post on WSHO registration.
WSH Coordinator. The occupier "shall not appoint any person as a workplace safety and health co-ordinator unless the person is one" who:
- "has successfully completed a training course to equip him to be a workplace safety and health co-ordinator"
- the occupier "reasonably believes is competent to perform the functions and duties" of a coordinator
- the occupier "reasonably believes has at least 2 years' practical experience relevant to the work to be performed"
Notice the difference. The officer rules put a register and a certificate between you and the person. The coordinator rule, in the part we read (regulations 5 to 9), has no register. The check is yours. If the occupier is later asked why a person was appointed, the answer is the occupier's reasonable belief, so it helps to be able to show what that belief rested on. That is our suggestion, not a requirement in the regulation.
What does the appointment give them to work with?
Duties and powers written into the regulations, which the occupier has to make workable.
The officer's duties are to assist the occupier "to identify and assess any foreseeable risk", to recommend measures to eliminate or reduce it, and to help put them in place. The coordinator's duties are narrower: to assist the occupier "to identify any unsafe condition in the worksite or unsafe work practice", to recommend measures, and to help implement them.
Both roles come with the same list of powers. The officer or coordinator may enter and inspect the workplace "at any reasonable time", inspect machinery and equipment, "require the production of workplace records, certificates, notices and documents", examine any person at work as needed, "assess the level of noise, illumination, heat or harmful or hazardous substances", and "investigate any accident, dangerous occurrence or occupational disease". The coordinator version says "worksite" and "worksite records".
Two things follow in plain terms:
- An appointee with no access cannot do the job. If your officer cannot get into the plant room or see the incident records, the powers in the regulation are on paper only.
- Both roles advise and help. The occupier decides. The wording is "assist" and "recommend". In the text we read, nothing moves the occupier's own duties onto the appointee. A recommendation that nobody with authority acts on achieves nothing.
MOM also lists what an officer's work looks like in practice, such as leading risk assessment teams, investigating incidents, and serving as secretary of a workplace safety and health committee.
What should happen in the first few weeks?
Put the appointment on paper, introduce the person, and give them what they need to start. None of this list is a legal requirement. It is how we would turn the regulations into a routine.
- Write the appointment. A short letter or memo naming the person, the role, the workplace or worksite, the start date, and the regulation it is made under
- File the evidence. For an officer, a copy of the MOM card and its expiry date. For a coordinator, the course certificate and whatever shows their two years of relevant experience
- Agree the reporting line. Who does the person report to, and who can approve a change? A name, not a department
- Give access. Site passes, records, incident reports and risk assessments, and the right to walk any area
- Tell the workforce and contractors. People should know who the officer or coordinator is and what they may ask for
- Set a first task. For example, go through the current risk assessments and list what is out of date
- Diarise the dates. Expiry or refresher date, and a review of whether the role is working
How does the appointment stay valid?
An officer's approval expires. A coordinator's training is expected to be refreshed.
Officer. The approval lasts two years, and renewal can be refused. MOM's renewal page says to renew "at least 60 days before" expiry. The details are in our WSHO registration post.
Coordinator. MOM wrote to construction companies in July 2024. Its circular "reminds Construction Companies to send WSH Coordinators who are appointed to work in their worksites to attend the WSH Coordinator Refresher Training every two years". It adds that attendance is recorded in MOM's training record system and that "MOM may conduct checks to ensure compliance of the training requirement". The circular is addressed to construction companies. Whether coordinators in other industries are covered in the same way is not something we could confirm from it.
What if the person leaves, or the project changes?
Treat a vacancy as urgent, and ask MOM about edge cases rather than guessing.
For a workplace in the Second Schedule, the regulation says it "shall have appointed in writing" an officer. Read plainly, a workplace whose officer has left, or whose approval has expired, no longer has one. We have not found MOM guidance on how long a gap is tolerated, so do not assume there is a grace period.
The regulations draw the line between the two roles at a contract sum of $10 million. We did not find anything in the text we read about a coordinator already in place when a contract sum changes. If that could apply to you, ask MOM before the change, not after.
Where does AnjouHealth fit, and where doesn't it?
We do not supply, train or register WSH Officers or WSH Coordinators. If you need a person for either role, that is a hire, a secondment or an appointment from an approved training and registration route, not something we provide.
What we do is support the person once they are in the role. An officer is asked to help identify and assess risk. For physical risks such as lifting, repetitive work and awkward postures, our Workplace Ergonomics Risk Assessment (WERA) gives them scored findings and recommendations to take forward. Our safety campaigns and educational talks can back up what the officer or coordinator is already telling the workforce. Neither replaces an appointment the law requires, and a talk from us is not the WSH Coordinator Refresher Training.
An appointment is the start of the role, not the end of the task
A letter naming someone does not make a workplace safer. What counts is whether the person is qualified for the role you gave them, whether they can get to the places and papers the regulations say they may ask for, and whether somebody with authority acts on what they recommend. Put the dates in a diary, and check at each one that the role is still working.
Next Steps: Give Your Officer or Coordinator Better Risk Data
If the person you have appointed needs scored findings on lifting, repetitive or fixed-posture work, our Workplace Ergonomics Risk Assessment is the place to start.

Frequently Asked Questions
The occupier of the workplace. The officer regulations say the officer "shall be appointed by the occupier of a workplace", and the coordinator regulations say the coordinator "shall be appointed by the occupier of every worksite" covered.
Yes. For workplaces in the Second Schedule, regulation 8(1) says the workplace "shall have appointed in writing" an officer. The coordinator regulation, in the text we read, does not use the words "in writing", but a written record is sensible.
A completed training course for the role, and the occupier must reasonably believe the person is competent and has at least two years of relevant practical experience.
The coordinator regulation does not set up a register the way the officer regulations do. The check rests on the training course and the occupier's reasonable belief.
MOM's July 2024 circular reminds construction companies to send their coordinators for refresher training every two years.
