On-site paramedic and medical cover for construction and industrial worksites.

Staffed first-aid rooms, standby cover for subcontractors, and paramedics on site for construction and industrial work across Singapore. What follows is what the law actually requires, and where cover above that floor makes sense.

Most enquiries we get for worksite cover are not about risk appetite. They are about a requirement someone else has set: a building management asking for a certified first-aider on a small telecoms job, or a main contractor asking for a paramedic to staff a first-aid room that has already been built. This page sets out what the Workplace Safety and Health Regulations require on a Singapore worksite, and where paramedic cover sits above that.

Where the law sets the bar, and where it stops

The Workplace Safety and Health (First-Aid) Regulations do not require a paramedic, nurse or doctor on an ordinary construction or industrial site. The legal floor is trained first-aiders at a set ratio, plus a first-aid room once a site is large enough. The only point at which a medical practitioner becomes a statutory requirement is work in a compressed air environment. Anything past that floor, including an on-site paramedic, is a decision you make for risk and response time, or because your main contractor or building management has made it a condition of being on site.

The first-aider ratio

Regulation 5(1) of the Workplace Safety and Health (First-Aid) Regulations sets the core rule: "Where more than 25 persons are employed in a workplace, there shall be appointed in the workplace as first-aiders who shall be readily available during working hours such number of persons as complies with the ratio of one first-aider for every 100 persons employed in the workplace or part thereof." The "or part thereof" matters in practice. A site with 120 workers needs 2 first-aiders under this ratio, not 1.2 rounded down to 1.

Regulation 5(3) extends the same ratio to shift work: if your site runs multiple shifts, each shift needs to independently meet the 1:100 ratio, not the site as a whole averaged across the day. A site that hits its numbers on the day shift but leaves the night shift short is not compliant.

Regulation 5(2) requires that appointed first-aiders have "successfully completed a training course acceptable to the Commissioner" and undergo re-training as required. In practice that means an Occupational First Aid certificate, which is valid for 2 years under the WSH Council's technical notes for the Occupational First Aid Course. If your certified first-aiders are due for renewal, our occupational first aid refresher covers that 2-year cycle; if you need to train first-aiders from scratch to hit the ratio, that is our occupational first aid course.

First-aid rooms and first-aid boxes

Regulation 6 sets the threshold for a dedicated room: "Unless otherwise permitted by the Commissioner in writing, where there are more than 500 persons at work in a workplace, there shall be provided and maintained a first-aid room of such standard as may be approved by the Commissioner." The regulations do not set out a fixed specification for what goes in the room. The standard is whatever the Commissioner approves for that workplace, decided case by case rather than published as a checklist.

Separately, regulation 4 requires every workplace to have a sufficient number of first-aid boxes, with each floor of a building needing its own sufficient provision. Each box has to be adequately equipped, properly maintained, checked frequently, clearly identified, well lit and accessible, and placed under the charge of a person the occupier appoints. Nothing other than first-aid requisites may be kept in it. Again, the regulations describe how the box has to be run, not a fixed contents list.

Failure to comply is an offence under regulation 8: an occupier who does not comply faces a fine of up to $20,000 or imprisonment of up to 2 years, or both, rising to a fine of up to $50,000 for a repeat offender.

Underground, compressed air and confined space work

Higher-risk categories of construction work carry their own rules on top of the general first-aid regulations. Under the Workplace Safety and Health (Construction) Regulations, regulation 89 requires at least 5 people trained in rescue procedures and resuscitation where 25 or more persons work underground, and at least 2 where there are between 5 and 24. Regulation 111(1) requires a medical practitioner only for work carried out in a compressed air environment, such as caisson or tunnelling work under pressure, and regulation 112(2) requires a first-aid room specifically for that work.

Confined space entry sits under its own instrument. Regulation 23(1) of the Workplace Safety and Health (Confined Spaces) Regulations requires a written rescue plan, appointed rescuers trained in rescue operations including first aid, and suitable rescue and reviving equipment, before anyone enters. That is a requirement for trained rescue personnel attached to the entry programme, not a general requirement for a paramedic on site.

Where paramedic cover fits

None of the above requires a paramedic. What we actually get asked for tends to come from two different directions. One is a site that already has the compliance side sorted, a proper first-aid room built out with the equipment in place, and needs it staffed for the working day or across shifts. The other is a smaller crew told by a building management that they need a certified first-aider on site as a condition of the work, which is a contractual requirement rather than something the Workplace Safety and Health Regulations themselves impose on a job that size.

Either way, the decision to bring in an on-site paramedic rather than relying on the statutory first-aider ratio is usually about response time and clinical capability close to higher-risk work, not about meeting a legal minimum that a paramedic was never required for. For the clinical scope a paramedic covers on site, including how that differs from a trained first-aider, see our paramedic services page.

Worksite types we cover

New build and superstructure sites

Sites crossing the 25-employee threshold where the 1:100 first-aider ratio starts to matter, and larger sites approaching 500 people where a first-aid room becomes a requirement.

Multi-contractor sites

Where the main contractor sets its own standby condition for every subcontractor on site, on top of whatever the Workplace Safety and Health Regulations already require.

Tunnelling and underground works

Rescue-trained personnel requirements under the Construction Regulations, and a medical practitioner where the work is in a compressed air environment.

Confined space entry programmes

A written rescue plan and rescuers trained in rescue operations including first aid, sitting alongside whatever cover the rest of the site already has.

Fit-out and demolition

Shorter-duration works with shift patterns that still have to meet the first-aider ratio on every shift, not just across the site as a whole.

Small crews under building management rules

Utility, telecoms and maintenance crews of a handful of people, standing up cover because the building management requires it as a condition of being on site.

Meeting the ratio with your own staff

Bringing in a paramedic does not remove the requirement to have appointed first-aiders on site under regulation 5. Most sites run both: their own trained first-aiders meeting the ratio, plus an external paramedic or staffed first-aid room for the higher-risk work or the periods where more clinical capacity is needed. If you need to train or renew first-aiders to hit the ratio, our occupational first aid course and refresher cover that. If the site also runs events, such as a topping-out ceremony or an open day, our event medical standby service handles that separately from day-to-day site cover.

FAQs

Industrial and worksite paramedic questions

Does Singapore law require a paramedic on a construction site?

No. The Workplace Safety and Health (First-Aid) Regulations set a legal floor of trained first-aiders, not a paramedic, nurse or doctor. Where more than 25 people are employed at a workplace, the regulations require one first-aider for every 100 people employed there "or part thereof", so 120 employees needs 2 first-aiders, not 1.2. A paramedic on site is a step above that legal minimum, bought for risk and response time, not to satisfy the regulations.

When does a construction site need a first-aid room?

Under regulation 6 of the Workplace Safety and Health (First-Aid) Regulations, a first-aid room is required "where there are more than 500 persons at work in a workplace", unless the Commissioner permits otherwise in writing. The regulations do not specify a fitted-out standard for the room; it has to be "of such standard as may be approved by the Commissioner", which is decided case by case rather than fixed in the text.

We already have a first-aid room. Can you just staff it?

Yes, that is one of the most common requests we get. Some sites have already built the room, sometimes with IT and equipment already fitted, and simply need it staffed with a paramedic or EMT for the working day or across shifts. Tell us the room, the shift pattern and the headcount, and we scope the staffing around what you already have.

What about confined space entry and underground work?

These sit under separate regulations. The Workplace Safety and Health (Confined Spaces) Regulations require a written rescue plan and appointed rescuers trained in rescue operations, including first aid, plus suitable rescue and reviving equipment, for any confined space entry. That is a requirement for trained rescue personnel, not a paramedic. The Workplace Safety and Health (Construction) Regulations separately require at least 5 people trained in rescue procedures and resuscitation where 25 or more people work underground, or at least 2 where there are 5 to 24. A medical practitioner is only required for work in a compressed air environment, such as caisson or tunnelling work under pressure, which also requires its own first-aid room under those regulations.

If the law does not require a paramedic, why do main contractors ask for one?

That requirement usually comes from the main contractor or the building management, not from the Workplace Safety and Health Act. It is a contractual condition written into the site agreement or the permit to work, often stricter than the statutory floor. We see this regularly: a subcontractor is told to provide standby cover as a condition of being on site, separate from anything the regulations themselves demand.

How long does an Occupational First Aid certificate last?

Two years, under the WSH Council's technical notes for the Occupational First Aid Course. After that, a first-aider needs to complete the refresher course to stay current for the workplace ratio. If your certified first-aiders are approaching that date, our occupational first aid refresher course covers the renewal.

Do you provide the paramedic, or are they your own staff?

We are a broker. Paramedics and EMTs deployed to your site are supplied and managed through our partner operator, not employed directly by us. That is the same partner operator behind our wider paramedic and ambulance services.
