In brief
On Tuesday 13 October 2026 three men died on a farm north of Herold's Bay, near George, while a fertiliser tank was being cleaned. [1][2] According to the company's statement, one worker collapsed inside the tank, two colleagues went in and brought him out and then lost consciousness, and the farm manager went in after them and also lost consciousness; all three died at the scene and the first worker survived. [1] The cause has not been established. [1][2][3] What is not in question is the rule that has applied to this kind of work in South Africa since 1986: regulation 5 of the General Safety Regulations allows a confined space to be entered only after a competent person has tested the air and certified in writing that it is safe, and where that cannot be done, only with breathing apparatus, a harness and line, and a person trained in resuscitation waiting outside. [4][5] This article sets out what that rule requires, and why the most dangerous moment in any confined space is the moment someone goes in to help.
What has been reported
The incident happened at about 13:30 on 13 October 2026. Police said the three men were overcome by a toxic substance "whilst allegedly cleaning a fertiliser tank", and opened an inquest docket. [2] Phosphoric acid was reported among the chemicals in the tank. [2] The company described the work as routine cleaning of an empty fertiliser tank to remove residue that had built up at the bottom. [1]
Accounts of the injuries differ. One report said twelve others were exposed, one critically; the company said the first worker was discharged from hospital the next morning and that seven other employees on site were screened and cleared. [1][2] We do not state a number.
On 20 October 2026 the Department of Employment and Labour was reported to have issued a prohibition notice to the employer and to have opened an investigation under section 31 of the Occupational Health and Safety Act into the circumstances of the deaths and whether adequate safety measures were in place. The Department said the tank, or whether it was a confined space, could not yet be singled out as the cause, that no findings of non-compliance had been announced, and that a decision on a formal inquiry would follow the investigation. [3] That report is from one outlet, so we treat the notice and the investigation as provisional until a second source carries them.
We do not name the farm, the company or the men who died, and nothing in this article should be read as a view on what went wrong in that tank. The point is the rule, which applies to every employer with a tank, pit or sump, and which is easy to forget precisely because the work is routine.
What the regulation says
The General Safety Regulations, made in 1986 and in force under the Occupational Health and Safety Act, define a confined space, in substance, as an enclosed or limited space in which hazardous substances may accumulate or an atmosphere deficient in oxygen may occur, and give as examples a chamber, tunnel, pipe, pit, sewer, container, valve, pump, sump or similar construction, equipment, machinery or object. [4][5] Regulation 5 then sets out, in order:
- Test first. The employer must ensure that a confined space is entered only after the air in it has been tested and evaluated by a person competent to pronounce on its safety, and that this person has certified in writing that the space is safe and will remain safe while anyone is inside. [4][5]
- If it cannot be certified safe, make it safe. Where the space may contain dangerous gas, vapour, dust or fumes, or less than 20 percent oxygen by volume, entry is allowed only once it has been purged and ventilated and steps have been taken to keep the atmosphere safe, and only once it has been isolated from pipes, ducts and other openings by blanking, or, where that is not practicable, by locking every potentially dangerous valve and cock with chains and padlocks. [4]
- If it cannot be made safe, protect the person going in. Where purging is not possible, entry is allowed only with breathing apparatus approved by the Chief Inspector, a safety harness with a rope leading outside and attended by a person outside, at least one person trained in resuscitation stationed immediately outside the entrance, and approved breathing and resuscitation apparatus ready at the entrance. [4]
- Flammable atmospheres. Entry is allowed only where the concentration of flammable gas does not exceed 25 percent of the lower explosive limit, or 10 percent where the work could create a source of ignition. [4]
- Nearby work. The same requirements apply, as far as practicable, to work next to a confined space where the proximity creates a hazard. [4]
Regulation 5 was not among the provisions changed by the two 2025 amending notices to the General Safety Regulations, which dealt with the general risk evaluation duty, first aid certificates, housekeeping, flooding, fire precautions and the penalty provision. [6] The rule stands as written.
Two things in that text deserve attention. First, the primary control is a piece of paper: a written certificate from a competent person, issued before entry. Second, the regulation plans for the rescue before anyone goes in. The person outside, the line, the harness and the resuscitation apparatus are there precisely so that nobody has to follow a collapsed worker into the same atmosphere.
Why the rescuers die
The pattern on the farm near George, as the company described it, is the one that safety regulators abroad have warned about for decades. In 1986 the United States National Institute for Occupational Safety and Health reported that more than 60 percent of confined space fatalities occurred among would-be rescuers. [7] That figure is from a single agency and is now forty years old, so we cite it as that agency's finding rather than as a current statistic.
Great Britain addresses the same risk in its own law. The Confined Spaces Regulations 1997 prohibit entry where the task can reasonably be done another way, require a safe system of work where entry is necessary, and forbid anyone from entering or working in a confined space unless suitable rescue arrangements have been prepared in advance; arrangements are not suitable if they do not reduce the risks to the rescuers themselves. [8] The South African regulation reaches a similar result through its requirement for a trained person and rescue equipment at the entrance. [4]
The instinct to go in after a colleague is human and it is immediate. The law's answer is not to forbid it but to make it unnecessary, by having the line, the harness and the trained person already in place.
Who the duty sits with
The duty in regulation 5 sits with the employer, or the user of the machinery, whose people go into the space. [4] It is a specific application of the general duty in section 8 of the Act to provide and maintain, as far as reasonably practicable, a working environment that is safe and without risk to health. [9][10] Where a person dies in an incident at work, section 24 requires the incident to be reported to an inspector, and section 31 allows an inspector to investigate it. [9][10]
That matters for businesses that do not think of themselves as having confined spaces:
- Farms: fertiliser and chemical tanks, silos, grain bins, wine and fruit processing vessels, borehole and pump chambers, slurry and effluent pits.
- Residential estates and sectional title schemes: sewer pump stations, conservancy and septic tanks, water reservoirs, valve chambers and manholes, usually entered by contractors at the request of the estate.
- Manufacturers and food processors: mixing vessels, holding tanks, pits under machinery, ducts and sumps.
Where a contractor does the entry, the contractor is the employer of the person going in. The business that commissioned the work still carries its own duties to people who are not its employees under section 9 of the Act, which we covered in Your Safety File Counts Employees. Section 9 Counts Everyone Else., and it is the business that knows what was last stored in the tank.
Five questions to ask before the next tank is cleaned
- Do we know where our confined spaces are? A written list, by location, of every tank, pit, sump, chamber and vessel that a person could enter. [4]
- Who is our competent person for air testing, and is the certificate written before entry? The regulation asks for a written certification, not a verbal all clear. [4]
- How is the space isolated? Blanking, or locked valves with chains and padlocks, recorded before entry. [4]
- Who stands outside, and are they trained in resuscitation? A named person, a line, a harness, and breathing and resuscitation apparatus at the entrance, every time. [4]
- What does the rescue plan say, and has everyone heard it? The plan should say, in plain words, that nobody goes in after a collapsed person without breathing apparatus. [4][8]
GRC Shop view
This section is interpretation, kept separate from the sourced facts above.
The confined space rule is old, short and clear, and it fails in a predictable way. Tank cleaning is occasional work. It happens once a season or once a year, often with a different team, and the written procedure, the gas detector's calibration record, the name of the competent person and the last rescue drill sit in different places, if they exist at all. On the day, the job looks routine, and routine is when nobody reaches for the file.
That is the gap our system is built for. Compliance files go stale; our system keeps yours current. A confined space register, the competent person's appointment and the record of each entry are exactly the kind of dated evidence that should be in one place and visible before a team is sent into a tank, not reconstructed by an investigator afterwards.
We will add the outcome of the Department's investigation to this page if it is published. Until then the only lesson we draw is the regulation's own: test before entry, and plan the rescue before anyone needs one.
