A diving instructor falsified their fitness-to-dive certificate, passed a pre-employment check nobody actually verified, and went on to work with students in open water. Nothing went wrong that day. It does not always end that way.

The Certificate That Nobody Checked

Occupational health screening exists for one reason: some jobs will kill you, or someone else, if the wrong person does them. Diving instructors, HGV drivers, crane operators, confined space workers. The medical certificate is the control measure. When it is fake, the control measure is theatre.

The problem is not isolated to diving. Across Irish workplaces, the verification of occupational health documentation is patchy at best. Employers collect certificates. They rarely confirm them. The issuing clinic is not always contacted. The doctor's registration is not always checked. The certificate goes in the file, the file goes in the cabinet, and the box is ticked.

This is not laziness in every case. A lot of employers genuinely do not know they can, or should, verify certificates directly with the issuing practitioner. The regulatory framework tells them to get the certificate. It is quieter about what to do with it once they have it.

What Irish Law Actually Requires

The Safety, Health and Welfare at Work Act 2005 places the duty on employers to manage health and safety risks, which includes fitness-for-work assessments where the role demands them. Specific regulations layer on top of that for particular industries. Night workers need health assessments under the Organisation of Working Time Act 1997. Drivers of commercial vehicles need medical fitness certificates to hold a Group 2 licence, overseen by the Road Safety Authority. Divers are covered under the Diving at Work Regulations.

None of these frameworks include a robust national system for cross-referencing certificates against a central register of occupational physicians. There is no equivalent of the driver licence lookup that a third party can use to verify a medical certificate in real time. If someone hands you a convincing-looking document, your main defence is a phone call to the clinic that supposedly issued it.

That phone call gets made less often than it should.

Who Bears the Risk

The obvious answer is the worker who should not have been cleared for duty. The less obvious answer is everyone around them.

A commercial diver with unmanaged cardiac arrhythmia is not only a risk to themselves. They are a risk to their dive buddy, to the rescue team, to the operation. An HGV driver with uncontrolled epilepsy on the M50 at 7am needs no further explanation. Distracted driving and impairment are already killing people on Irish roads without adding falsified fitness certificates to the mix.

Employers carry liability too. If a worker causes a fatality and the post-incident investigation reveals the occupational health certificate was not genuine, the employer's due diligence record is the first thing the Health and Safety Authority examines. "We got a cert" is not the same as "we verified a cert." Courts and investigators know the difference.

The Gaps in the System

Three problems sit at the core of this.

Verification is voluntary. No Irish regulation currently mandates that employers contact the issuing clinic to confirm authenticity. The duty of care argument is there in law, but the specific requirement to verify is not.

Occupational health is fragmented. Ireland does not have a statutory occupational health service that every employer is required to use. Provision is patchy, particularly for SMEs. A small employer in rural Roscommon may be using whoever is available locally, without any standard process for issuing or recording certificates.

Workers under pressure falsify. This needs saying plainly. When someone needs a job and knows a genuine medical assessment might disqualify them, some will take the risk of faking it. That is a systemic pressure, not a moral failing unique to one individual. If the financial consequence of failing a medical is losing work, and the verification system is weak, falsification becomes rational in a bleak kind of way.

What Better Looks Like

Some sectors do this well. Aviation medical certificates for pilots include a certificate number traceable through the Irish Aviation Authority's records. The employer, if they bother, can verify authenticity in minutes. That model works. It is not technically complex. Other high-risk sectors could adopt it.

For employers operating right now without waiting for regulatory reform, the baseline should be:

  • Contact the issuing clinic or physician to confirm the certificate was issued and remains valid.
  • Keep a log of that verification, with the date, the person contacted, and the response.
  • Set calendar reminders for expiry dates. A certificate that was valid at hire is not automatically valid three years later.
  • For roles with significant risk, use a named occupational health provider and build a relationship with them rather than accepting certificates from whichever GP the worker attended.

None of this is expensive. A phone call costs nothing. The alternative has a known price, and it is measured in prosecutions and funerals.

The Deeper Problem

The diving instructor story is a symptom. The condition is a compliance culture that values the presence of documentation over the quality of it. A certificate in a file is not the same as a fit worker in a role. The difference matters.

Psychological safety in Irish workplaces gets talked about a lot these days, and rightly so. Physical fitness for the actual demands of the job gets less attention than it deserves. Both are safety-critical. Both depend on honest, verified information.

The regulator has tools to push this. Requiring verifiable certificate numbers, mandating a register of occupational physicians authorised to sign fitness-for-work assessments, and building audit of occupational health records into routine HSA inspections would all move the dial. That is a policy ask, not a fantasy. Other jurisdictions have done it.

Until then, the phone call is on you.
