In brief
Almost every South African employer counts its safety obligations off the payroll. The Occupational Health and Safety Act does not. It counts them off the premises. A business with 30 employees at one address must designate a health and safety representative in writing, and needs a first-aid box and a trained first aider. The same business with 30 employees split across three branches of 10 needs no representative at all, and instead needs three first-aid boxes; and the day any one branch takes on an eleventh employee, that branch also needs its own trained first aider. Same company, same headcount, same payroll, entirely different set of duties, and the thing that decides it is the address. [1][2] This is not a technicality and it is not an interpretation. The Act defines a workplace as premises, and then hangs its thresholds on that definition, word by word.
What the Act actually says
The definition does the work. Section 1 of the Occupational Health and Safety Act 85 of 1993 defines a workplace as "any premises or place where a person performs work in the course of his employment". [1] Premises or place. Not employer, not company, not entity. Once that definition is in hand, three thresholds read very differently.
Health and safety representatives. Section 17(1) requires every employer who has more than 20 employees "at any workplace" to designate, in writing and for a specified period, health and safety representatives "for such workplace, or for different sections thereof". [1] The trigger counts employees at the workplace, and the designation attaches to the workplace.
Health and safety committees. Section 19(1) requires an employer to establish one or more health and safety committees "in respect of each workplace" where two or more representatives have been designated. [1] Each workplace, in the Act's own words.
First aid. General Safety Regulation 3 requires a first-aid box where more than five employees are employed "at a workplace", and a trained first aider where more than 10 employees are employed "at a workplace", at the ratios of one per 100 in shops and offices and one per 50 elsewhere. [2][3] Again the count is taken at the premises.
The arithmetic, worked both ways
Take a business with 30 employees and nothing else changed.
All 30 at one address. More than 20 at that workplace, so representatives must be designated in writing under section 17(1), at the section 17(5) ratio of at least one for every 100 employees or part thereof in shops and offices and one for every 50 elsewhere. [1] At 30 employees that is one representative; a committee under section 19(1) follows only if the employer designates two or more. More than 10 employees means a first-aid box and at least one first aider. One site, one representative, one box, one first aider.
Ten at each of three addresses. No workplace has more than 20 employees, so section 17(1) is not triggered anywhere and no representative is required at all. With no representatives there are no committees. But each of the three has more than five employees, so each needs its own first-aid box. None has more than 10, so none yet needs a trained first aider, and that is the point to watch: the eleventh hire at any one branch creates a first-aid appointment at that address, whatever the company total says. Three boxes, no representatives, no committee, and a first-aider duty one hire away at every branch.
The second business is not less regulated than the first. It is differently regulated, and the difference is invisible on a payroll report. An employer that grew by opening branches, rather than by filling one building, quietly moved from one set of duties to another without any decision being taken and usually without anybody noticing. The most common failure is the simplest: head office has the box, the first aider and the file, and the branch opened eighteen months ago has a kettle and a laptop.
The appointment nobody re-reads
Section 16 sits above all of this. Section 16(1) puts on the chief executive officer the duty to ensure, as far as is reasonably practicable, that the employer's duties under the Act are properly discharged. [1] That duty is not divisible by address. It runs to every workplace the business operates, including the one that opened last quarter.
Section 16(2) is the provision behind the letter almost every South African business calls its "16.2 appointment", under which the chief executive officer assigns duties to a person under their control. Two things about it are worth stating plainly. First, section 16(3) provides that such an assignment does not relieve the employer of any responsibility or liability under the Act. [1] Delegation moves the work, not the accountability. Second, an assignment is commonly scoped to an area rather than to the whole business: commentary describes the appointee as responsible for health and safety "at the designated area of appointment", and notes that different managers may be assigned duties for different workplaces, regions, divisions or functions. [4][5] That is sensible practice, and it has a consequence that is rarely followed through. If the letter names a building, it does not reach the building that did not exist when it was signed.
One point is marked provisional because we have found only one source that states it directly, and our standard is two. Section 17(1) expressly requires representatives to be designated "in writing". [1] The text of section 16(2) carries no equivalent writing requirement, and one commentary states that a written acknowledgement is useful for the file but does not itself create the statutory duty. [5] We flag this rather than assert it, and we would not advise anyone to stop writing appointments down: the written letter is how a business proves, a year later and to somebody who was not there, who held the duty and for which premises.
Why the two usual answers do not reach this
An employer reading the above will often have one of two reasons to believe it is already covered, and both are reasonable, and neither reaches the problem.
"We already have someone." Very likely true, and their work is probably good. But the appointment, the register and the box are almost always at the address where that person sits. The branch, the depot, the second yard or the satellite office is not in the letter, and nothing about a retained consultant's normal cycle causes a new address to appear in the file. The address arrived through a lease, a sales decision or an acquisition, and none of those routes passes across a safety desk.
"We have just been audited." Also true, and the report was almost certainly accurate. An audit tests the premises it visited on the day it visited them. A site that was not in the sample is not in the finding, and a site that opened after the audit cannot be. The report stays clean while the estate changes underneath it.
Neither of these is negligence. They are both the same structural fact: the thing that changes your duties under this Act is a property decision, and property decisions are not routed to the safety file.
GRC Shop view. This is opinion and forecast, clearly marked as such. We expect the per premises point to become more visible rather than less, for two reasons. The inspectorate is growing, and a larger inspectorate visits more addresses per employer rather than the same address more often. And the joint inspection, which now combines labour, safety, compensation and immigration checks in one unannounced visit, arrives at whichever site it arrives at, which will frequently not be head office. The wider point is the one we keep returning to. The audit is fine. What fails is afterwards, because closing items out happens in email while the evidence scatters across folders, so a year later the report still reads clean and the file no longer matches it. That is not neglect. It is that nothing holds the pieces together between audits, and a new address is exactly the kind of change that nothing holds. Compliance files go stale. Our system keeps yours current.
What to do this week
Write down every address at which any employee of yours performs work. Include the ones you do not think of as sites: the storeroom on the other side of town, the branch inside somebody else's building, the yard, the second shop. The test is the Act's own, premises or place where a person performs work in the course of their employment.
Against each address, put the number of employees based there. Then apply the three thresholds to each line separately: more than five for a first-aid box, more than 10 for a first aider, more than 20 for representatives designated in writing, two or more representatives for a committee.
Then read your existing section 16(2) letter and ask one question of it: which address does it name, and which of the addresses on your list is not covered by any letter at all.
