LEV testing - RIDDOR
Failing extraction is not only a control problem - it can become a reporting one. When poor LEV lets a worker develop an occupational disease like asthma from a sensitiser, that disease can be reportable to the authorities under RIDDOR. It is a stark reminder that the consequence of extraction that does not work is not abstract: it is a real illness in a real person, with legal duties attached.
The short answer
RIDDOR - the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations - requires certain work-related illnesses to be reported to the authorities. Occupational asthma is reportable when a worker whose job involves significant or regular exposure to a known respiratory sensitiser is diagnosed by a doctor with the condition. Since LEV is often the control keeping exposure to such sensitisers down, extraction that fails to control it can be part of the chain that leads to a reportable disease. So poor LEV connects to RIDDOR through its consequence: if failing extraction lets a worker develop a reportable occupational illness, a legal reporting duty follows - alongside the far greater cost of the illness itself.
What RIDDOR is
RIDDOR - the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations - places a legal duty on employers and others to report certain serious work-related events to the enforcing authority. Among the things it covers are specified occupational diseases: illnesses caused by work that, when they occur and are diagnosed, must be reported. The purpose is partly to ensure serious work-related harm is recorded and can be acted on, and partly to give the authorities visibility of where work is making people ill. Reporting is not optional where a reportable event occurs; it is a duty in its own right.
This matters for LEV because some of the diseases RIDDOR covers are exactly the airborne-exposure illnesses that LEV exists to prevent. LEV controls exposure to substances that, uncontrolled, can cause reportable occupational diseases - so there is a direct line between an extraction system's job and the reporting regime. When the control works, the disease is prevented and there is nothing to report. When the control fails and a worker becomes ill, the illness can be a reportable one. So RIDDOR is where the failure of an LEV can surface as a formal, legal consequence - the reporting of a disease the extraction should have prevented.
Occupational asthma
The clearest example is occupational asthma. Asthma caused by work is reportable under RIDDOR when the affected person's job involves significant or regular exposure to a known respiratory sensitiser, and a doctor has diagnosed the condition. Respiratory sensitisers - substances that can make the airways react so that further exposure triggers asthma - are precisely the kind of hazard LEV is often installed to control, from flour dust in a bakery to certain fumes and chemicals in industry. So a worker exposed to a sensitiser that the LEV was meant to capture, who develops occupational asthma, is in the situation RIDDOR is written for.
The requirement for a doctor's diagnosis is worth noting: the report follows a confirmed medical diagnosis of the condition, not a suspicion. But once that diagnosis is made in a worker with the relevant exposure, the reporting duty applies. This is a sobering connection for anyone responsible for LEV, because it means the extraction failing at its job can lead directly to a diagnosed disease in an employee and a formal report to the authorities. The sensitiser that the LEV should have been capturing has instead sensitised a worker's airways - the exact harm the control existed to prevent, now realised, diagnosed, and reportable.
The chain from poor LEV to a report
The connection between poor LEV and a RIDDOR report runs through cause and consequence. LEV is there to keep exposure to a hazardous substance controlled; if the extraction fails - loses capture, runs below what it needs, is not maintained - then exposure is no longer controlled, and workers breathe more of the hazard than they should. Over time, that uncontrolled exposure to a sensitiser is what can lead to occupational asthma. So failing extraction sits at the start of a chain that can end in a diagnosed, reportable disease: poor LEV, uncontrolled exposure, sensitisation, asthma, a report.
This reframes what a failing LEV really costs. The immediate view of poor extraction is a compliance or performance problem - a test that might be failed, a system that needs fixing. But its ultimate consequence is a person made ill, and RIDDOR is where that consequence becomes formally visible. A reportable disease is not just a piece of paperwork; it is the documentation of real harm to a real worker, harm the extraction was supposed to prevent. And a pattern of such reports, or the circumstances behind one, can draw the attention of the authorities to how the hazard was being controlled - putting the state of the LEV, and whether it was properly maintained and tested, directly in the frame.
Why this makes testing matter more
The RIDDOR connection is, in the end, an argument for taking LEV testing seriously - because the whole chain it describes is preventable at the start. Keeping the extraction genuinely effective, through maintenance and thorough examination, is what stops the exposure that leads to the disease that leads to the report. A system confirmed by testing to be controlling the sensitiser is a system preventing the sensitisation - so the periodic examination is not just a compliance exercise but a link in preventing a reportable disease from ever arising. The test protects the worker, and in doing so removes the circumstances a RIDDOR report would document.
Seen this way, the connection between LEV and RIDDOR is not a threat but a clarification of the stakes. The reason to keep extraction tested and working is that the alternative - failing extraction, uncontrolled exposure - has a human cost measured in diagnosed disease, which the reporting regime makes formal and visible. Testing is how a business stays on the right side of that: confirming the control works, so the exposure is prevented, so the disease does not develop, so there is no report to make and no worker harmed. RIDDOR shows what is at the end of the road if the control fails; testing is how you make sure you never travel it. Prevention is the whole point, and effective, tested LEV is the prevention.
The takeaway
RIDDOR requires certain work-related illnesses to be reported, and occupational asthma is reportable when a worker with significant or regular exposure to a known respiratory sensitiser is diagnosed by a doctor with the condition. Since LEV is often the control keeping exposure to such sensitisers down, failing extraction can sit at the start of a chain - poor LEV, uncontrolled exposure, sensitisation, asthma - that ends in a diagnosed, reportable disease. Poor extraction connects to RIDDOR through its consequence.
That connection reframes what failing LEV really costs: not just a failed test or a system to fix, but a real illness in a real worker, made formally visible by a legal reporting duty, with the state of the extraction and its maintenance liable to come into question. And it makes the case for testing plainly: keeping the extraction genuinely effective, confirmed by thorough examination, prevents the exposure that leads to the disease and the report. RIDDOR shows what lies at the end of the road if the control fails; effective, tested LEV is how you make sure you never reach it.
Questions
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations - a legal duty to report certain serious work-related events to the enforcing authority, including specified occupational diseases. Its purpose is to record serious work-related harm and give the authorities visibility of where work is making people ill.
When the affected person's job involves significant or regular exposure to a known respiratory sensitiser, and a doctor has diagnosed the condition. The report follows a confirmed medical diagnosis in a worker with the relevant exposure - not a suspicion - but then the reporting duty applies.
Through cause and consequence. LEV controls exposure to hazardous substances including sensitisers; if it fails, exposure is no longer controlled, and uncontrolled exposure to a sensitiser can lead to occupational asthma. So failing extraction sits at the start of a chain that can end in a diagnosed, reportable disease.
No - it documents real harm to a real worker, harm the extraction was supposed to prevent. And the circumstances behind a report can draw the authorities' attention to how the hazard was being controlled, putting the state of the LEV and whether it was properly maintained and tested directly in the frame.
It can contribute. A reportable disease, or the circumstances behind it, can prompt scrutiny of how exposure was being controlled - and if the LEV was not properly maintained and tested, that becomes part of the picture. The reporting regime makes the consequence of failed control formally visible.
By preventing the whole chain at the start. Keeping the extraction genuinely effective, confirmed by thorough examination, stops the exposure that leads to the disease and the report. A system tested to be controlling the sensitiser is preventing the sensitisation - so testing protects the worker and removes what a report would document.
Our thorough examination confirms your LEV is genuinely controlling the sensitisers and hazards it was installed for - preventing the exposure that can lead to a diagnosed, RIDDOR-reportable disease.
