How Many First Aiders Are Required in a Workplace in South Africa? Calculator & Legal Guide
Updated: 4 days ago
Quick Answer
How many first aiders are required in South Africa, Where more than 10 employees are employed at a South African workplace, General Safety Regulation 3 requires at least one person with a valid first-aid competency certificate for every group of up to 50 employees. For a shop or office, the ratio is one for every group of up to 100 employees. The required person must be readily available during normal working hours.
Where more than five employees work at the workplace, the employer must also provide an accessible first-aid box or boxes. Even below these numerical thresholds, employers remain responsible for taking reasonable steps to ensure prompt first-aid treatment following injury or emergency. (Alternative Waste Treatment Guide)
The statutory number, however, is only the first calculation.
The employer must still ask:
Are enough properly certificated first aiders actually available where and when people are working?

The safest way to calculate your workplace requirement is to separate the statutory headcount baseline from the real operational coverage test.
Step 1: Count Employees at This Workplace
Calculate employees for the workplace being assessed.
Do not automatically combine employees working at completely separate branches or workplaces into one national headcount.
For example, a company with a Cape Town warehouse and a separate office should review the first-aid arrangements at each workplace rather than assuming one first aider at head office solves the warehouse requirement.
Step 2: Identify the Workplace Type
The numerical ratio depends on the workplace category.
Workplace | Statutory ratio once Regulation 3(4) applies |
Shop or office | 1 first aider per group of up to 100 employees |
Other workplace | 1 first aider per group of up to 50 employees |
The regulation applies the certificated-first-aider requirement where more than 10 employees are employed. (Alternative Waste Treatment Guide)
If there is genuine uncertainty about whether a particular operation falls within the shop/office classification, do not manipulate the category merely to obtain the lower numerical requirement. Confirm the appropriate classification for the actual workplace.
Step 3: Calculate the Statutory Baseline
For workplaces other than shops or offices:
Required baseline = employees ÷ 50, rounded upward to the next whole person.
For shops and offices:
Required baseline = employees ÷ 100, rounded upward to the next whole person.
Examples:
Employees | General workplace | Shop / office |
10 | Regulation 3(4) threshold not yet triggered | Regulation 3(4) threshold not yet triggered |
11 | 1 | 1 |
49 | 1 | 1 |
50 | 1 | 1 |
51 | 2 | 1 |
75 | 2 | 1 |
100 | 2 | 1 |
101 | 3 | 2 |
150 | 3 | 2 |
200 | 4 | 2 |
201 | 5 | 3 |
Important: a zero under the Regulation 3(4) calculation does not mean an employer has no first-aid responsibility. Regulation 3(1) still requires reasonable steps to ensure prompt treatment, while the first-aid-box requirement begins once more than five employees are employed.
Step 4: Calculate Your Actual Coverage Gap
Now ask:
How many people with current, acceptable first-aid competency certificates are actually available during the working period being assessed?
A useful employer diagnostic is:
Coverage gap = statutory baseline − currently available valid first aiders
Never allow the answer to fall below zero.
For example:
Item | Result |
Warehouse employees | 117 |
Statutory baseline | 3 |
Current valid first aiders | 2 |
Available on this working period | 1 |
Paperwork gap | 1 |
Actual availability gap | 2 |
That distinction matters.
The employer may have two certificates in the safety file yet still have only one trained person physically available.
What Does South African Law Actually Require?
Prompt First-Aid Treatment
General Safety Regulation 3(1) requires employers to take reasonable steps necessary under the circumstances to ensure that persons at work receive prompt first-aid treatment in the event of injury or emergency. (Alternative Waste Treatment Guide)
That obligation exists before we even reach the numerical ratio.
The More-Than-Five-Employee First-Aid Box Rule
Where more than five employees work at a workplace, the employer must provide a first-aid box or boxes at or near the workplace which are available and accessible for treatment.
The contents must also take account of likely injuries, the nature of the activities and the number of employees. (Alternative Waste Treatment Guide)
The More-Than-Ten-Employee First-Aider Rule
Where more than ten employees are employed, Regulation 3(4) provides for:
one person per group of up to 50 employees, or
one person per group of up to 100 employees in a shop or office.
The 2005 amendment strengthened the wording by requiring the relevant person to be designated in writing, readily available during normal working hours and in possession of a valid certificate of competency issued through the prescribed approved route. (Government of South Africa)
Why “Readily Available” Matters
This is one of the most commercially and operationally important phrases in the regulation.
The legal requirement is not merely:
“Does somebody somewhere in the company possess a certificate?”
It is whether the necessary person is readily available during normal working hours. (Government of South Africa)
That changes how employers should think about leave, shifts, work-from-home schedules, satellite offices, warehouses, production areas and geographically separated sites.
The Compliance Trap: Enough Certificates Does Not Mean Enough Coverage
A training matrix can look perfect while the real emergency-response system is weak.
Shift Coverage
If every trained first aider works the day shift but production continues at night, the certificates in the file do not automatically solve the night-shift availability problem.
Do not automatically multiply the statutory ratio by the number of shifts. Instead, test whether the required coverage is actually available during each operating period.
Leave and Absence
The statutory baseline can become operationally fragile where only the minimum number of people have been trained.
Annual leave, illness, training, travel or resignation can immediately expose a coverage gap.
Multiple Buildings and Work Areas
A large factory may technically have enough certificated people overall but still have poor practical response coverage if all trained staff work far from the highest-risk area.
Multiple Workplaces and Branches
A first aider employed at one branch cannot be treated as immediately available at another workplace 30 kilometres away.
Assess the actual workplaces and operating arrangements.
Remote or High-Risk Areas
A workshop, production floor, loading yard or remote work area may justify stronger practical coverage than a simple headcount calculation suggests.
The statutory ratio is the starting point—not an excuse to stop thinking.
First Aider Coverage Stress Test
Before deciding that your workplace has enough first aiders, answer these questions:
Employer question | Yes | No |
Do we meet the statutory numerical baseline? | □ | □ |
Are those people actually available during working hours? | □ | □ |
Does each active site have realistic first-aid access? | □ | □ |
Do leave and absence arrangements have backup coverage? | □ | □ |
Are certificates still valid and retrievable? | □ | □ |
Are first-aid boxes available and accessible? | □ | □ |
Do higher-risk substances require additional specific preparation? | □ | □ |
Do employees know who the first aiders are? | □ | □ |
Is the training matrix current? | □ | □ |
A “no” does not automatically prove a statutory offence.
It does identify something the employer should investigate before relying on the safety file as evidence of readiness.
Workplace Examples: How Many First Aiders Do You Need?
Office With 75 Employees
An office with 75 employees falls below the first 100-person shop/office group threshold.
Statutory baseline: 1.
But if that employee regularly travels, works remotely or is frequently absent, the employer should examine whether one trained person creates resilient real-world coverage.
Warehouse With 75 Employees
A warehouse is not automatically treated as an office simply because it has an administration section.
Using the general-workplace calculation:
75 ÷ 50 = 1.5
Round upward.
Statutory baseline: 2.
If the warehouse operates separate day and night shifts, actual availability still has to be tested.
Factory With 120 Employees
120 ÷ 50 = 2.4
Round upward.
Statutory baseline: 3.
A factory with machinery, hot work, cutting equipment, chemicals or multiple departments should then assess whether the baseline provides adequate practical emergency-response coverage.
Office With 180 Employees
180 ÷ 100 = 1.8
Round upward.
Statutory baseline: 2.
The employer should then test floors, departments, hybrid work schedules and absence cover.
Multi-Site Employer
Consider:
Site | Employees | Category | Baseline |
Head office | 45 | Office | 1 |
Warehouse | 60 | Other workplace | 2 |
Factory | 110 | Other workplace | 3 |
This employer should not conclude:
205 employees = one single calculation.
Its real first-aid arrangements depend on where people actually work.
High-Risk Workplaces: Do Not Use a Fake 1-in-10 Rule
One of the most damaging pieces of recycled South African First Aid content is the blanket claim that every high-risk workplace legally requires:
one first aider per 10 employees
or sometimes:
one per 25 employees.
General Safety Regulation 3 does not establish those as universal high-risk employee ratios.
The current SSA article already correctly rejects that myth, and that position should be strengthened rather than weakened. (Swift Skills Academy)
What Regulation 3 Actually Says
Start with the statutory 1:50 or 1:100 calculation where applicable.
Then examine workplace risks, layout, availability, emergency arrangements and any other applicable legal, client, industry or site-specific requirements.
Hazardous Substances Require More Than a Headcount Calculation
Regulation 3 goes further where high-risk, toxic, corrosive or similar hazardous substances are used, handled, processed or manufactured.
The relevant first-aid worker must receive training in the first-aid procedures necessary for injuries that may result from those activities, including appropriate emergency procedures. The regulation also addresses eyewash and emergency-shower arrangements for specified exposure hazards. (Alternative Waste Treatment Guide)
So the right question is not:
“Can I find a smaller or larger ratio online?”
It is:
“Does our first-aid system match our actual workplace hazards?”
What About First-Aid Boxes, Signage and Emergency Equipment?
Where more than five employees work at the workplace, the employer must provide accessible first-aid boxes.
Regulation 3 also requires the employer to consider likely injuries, workplace activities and employee numbers when determining suitable first-aid-box contents.
A prominent notice or sign must indicate where the first-aid box or boxes are kept and identify the person in charge. (Alternative Waste Treatment Guide)
For hazardous chemical or biological exposure risks, additional emergency facilities may be required, including eyewash or emergency-shower arrangements in the circumstances described by the regulation. (Alternative Waste Treatment Guide)
The first aider, the equipment and the emergency procedure have to function as one system.
What Evidence Should an Employer Keep?
A strong employer file should make first-aid readiness easy to demonstrate.
At minimum, the business should be able to reconcile:
Evidence | What to verify |
Employee name | Correct person |
Workplace / branch | Where the person works |
Department | Where they are normally based |
Shift | When they are available |
Programme | Exact training completed |
Certificate number | Traceable evidence |
Issue date | Training chronology |
Expiry / stated validity | Current status |
Written designation | Where applicable |
Backup first aider | Absence resilience |
First-aid box responsibility | Equipment control |
Training matrix | Organisation-wide oversight |
The key is reconciliation.
A certificate register, staff roster and workplace headcount should tell the same story.
What Happens If the Calculator Finds a Training Gap?
Suppose a warehouse employs 126 people.
The statutory numerical baseline is:
126 ÷ 50 = 2.52 → 3 people
The company currently has three certificate holders.
That looks compliant.
But then HR checks actual deployment:
One has resigned.
One works permanently at another branch.
One is available at the warehouse.
The training file says three.
Operational availability says one.
That is exactly why this article should no longer be a simple ratio guide.
The useful employer question becomes:
How many valid, suitable and actually available first aiders do we have at this workplace compared with the number we require?
That is the gap the business must resolve.
Swift Skills Academy's Current Workplace First Aid Route
Swift Skills Academy's current Cape Town First Aid pathway is the Basic Emergency First Aid Responder SP-230801 programme.
The live course page currently identifies the programme as NQF Level 2, two credits, with public training in Cape Town and on-site company training options. (Swift Skills Academy)
The article should mention that route for context, but it should not start trying to outrank the commercial page for broad transactional terms such as “First Aid Training Cape Town”.
The money page owns that intent.

Frequently Asked Questions
How many first aiders are required for 25 employees in South Africa?
If the workplace has more than ten employees, one certificated first aider would satisfy the numerical baseline under Regulation 3(4), whether the workplace is a shop/office or another workplace. Actual availability and risk still need to be considered. (Government of South Africa)
How many first aiders are required for 60 employees?
For a general workplace, the baseline would be two. For a shop or office, the numerical baseline would be one.
How many first aiders are required for 100 employees?
For a general workplace, the baseline is two. For a shop or office, the baseline is one.
How many first aiders are required for 101 employees?
For a general workplace, the baseline becomes three. For a shop or office, it becomes two.
Does every workplace legally need a first aider?
Regulation 3(4)'s numerical certificated-first-aider rule applies where more than ten employees are employed. The employer still has a broader obligation to make reasonable arrangements for prompt first-aid treatment even below that threshold. (Alternative Waste Treatment Guide)
When is a first-aid box required?
Where more than five employees are employed at a workplace, a first-aid box or boxes must be provided at or near the workplace and be available and accessible. (Alternative Waste Treatment Guide)
Do construction sites automatically require one first aider for every 10 workers?
No universal 1:10 first-aider ratio appears in General Safety Regulation 3. Other applicable rules, risk assessments, client specifications or workplace circumstances can justify additional arrangements, but they should not be falsely described as the general Regulation 3 ratio.
Does each shift need its own first aider?
The regulation requires the applicable person to be readily available during normal working hours. Employers operating shifts should therefore test whether adequate coverage actually exists while each shift is operating rather than simply counting certificates held elsewhere in the business. (Government of South Africa)
Does a high-risk workplace need extra first-aid training?
Where high-risk, toxic, corrosive or similar hazardous substances are involved, Regulation 3 specifically requires relevant first-aid procedures and emergency preparation for the injuries that may result. (Alternative Waste Treatment Guide)
Final Word
The correct first-aider calculation is not:
“How many certificates does our company own?”
It is:
“How many appropriately certificated people must be available at this workplace—and are they actually available when the work is happening?”
Start with the statutory employee ratio.
Then test workplace type, employee numbers, current certificate status, actual availability, site layout, shifts and workplace hazards.
That is how an employer turns First Aid from paperwork into a functioning emergency-response system.
