Understanding asbestos in the workplace
Asbestos is the single biggest cause of work-related deaths in Ireland and the UK. It is not a hazard from the distant past - it is still hidden inside millions of buildings put up or refurbished before the year 2000. Every day, workers across construction, maintenance, facilities, healthcare, education and public buildings can disturb hidden asbestos-containing materials (ACMs) during drilling, refurbishment, repairs and routine maintenance.
The danger is invisible. Asbestos fibres are far too small to see and have no smell, so you can breathe them in without ever knowing. That is why awareness matters so much: the goal is to recognise where asbestos is likely to be, leave it undisturbed, and report it - long before anyone is exposed.
Why asbestos is so dangerous
When an ACM is damaged or disturbed, microscopic fibres are released into the air. Once inhaled, they can lodge deep in the lungs and the lining around them, where they stay for life. There is no safe level of exposure, and the diseases asbestos causes can take decades to appear. The main asbestos-related diseases are:
- Mesothelioma - an aggressive, almost always fatal cancer of the lining of the lungs or abdomen, caused almost exclusively by asbestos
- Asbestos-related lung cancer - significantly more likely in exposed workers, especially those who also smoke
- Asbestosis - progressive scarring of the lungs that causes breathlessness and respiratory failure
- Pleural plaques and pleural thickening - markers of past exposure that can impair how well the lungs work
Because these diseases can appear 15 to 60 years after the first exposure, a worker may feel completely fine for decades before becoming ill. That long delay is exactly why prevention through awareness, not treatment, is the only reliable protection.
How to recognise asbestos before you start work
You cannot tell whether a material contains asbestos just by looking at it - it has to be assumed, checked or tested. Before any work that could disturb the fabric of an older building, follow these steps:
- Check the asbestos register - The duty holder must keep a register and survey showing where known and presumed ACMs are, and their condition. Always check it first.
- Assume the worst for pre-2000 buildings - If the building was built or refurbished before 2000 and the material has not been tested, treat it as if it contains asbestos.
- Know the common ACMs - Lagging, sprayed coatings, insulating board, asbestos cement, textured coatings (such as Artex) and floor tiles are all typical ACMs.
- If in doubt, stop - Do not drill, cut, sand or break a material you cannot identify. Apply STOP-CHECK-REPORT and have it assessed by a competent person.
This is the heart of asbestos awareness: not removing or repairing asbestos yourself, but recognising the risk, avoiding disturbance, and getting the right people involved. Removal and higher-risk work must always be left to trained or licensed asbestos contractors.
The best way to prevent asbestos disease is simple: do not disturb what you cannot identify. Check the register, leave suspect materials alone, report your concern, and let a competent person decide what happens next.
Where asbestos risk is highest
Asbestos can be found in almost any older building, but some kinds of work disturb it far more often than others:
Construction and demolition
Drilling, cutting, stripping out and demolishing older structures is where asbestos is most often disturbed. Awareness training is essential for everyone working on the fabric of a pre-2000 building.
Maintenance and the trades
Electricians, plumbers, heating engineers, carpenters, painters and decorators routinely work in risers, ceiling voids and around old lagging, insulating board and textured coatings - all common ACMs.
Healthcare and education estates
Many hospitals, clinics, care homes and schools were built before 2000. Estates, caretaking and maintenance teams can meet asbestos in pipe lagging, insulating board and floor tiles during everyday repairs.
Facilities and property management
Caretakers, facilities teams and housing maintenance staff work on the fabric of older premises, where asbestos may be hidden in ceilings, service ducts and plant rooms. Checking the register before any task is essential.
Roofing and cabling
Asbestos cement was widely used for roof sheets, cladding, gutters, downpipes and flues. Roofers and cabling installers can disturb these materials when cutting, removing or running new services.
The importance of Asbestos Awareness Training
Recognising the risk is the first step. To stay safe and meet the law, workers need comprehensive Asbestos Awareness Training that covers:
- What asbestos is, the types of asbestos and why the fibres are so dangerous
- The health risks, including mesothelioma, lung cancer and asbestosis
- How to recognise asbestos-containing materials and where they are commonly found
- How to use the asbestos register, survey and management plan before work starts
- The STOP-CHECK-REPORT procedure if asbestos is found or suspected
- The basics of PPE and RPE, and the clear limits of awareness training
- Your legal duties and your employer's duties under Irish asbestos law
Our online Asbestos Awareness Course covers all these topics, giving workers the knowledge to recognise ACMs and avoid disturbing them. The course takes approximately 45 minutes and results in an instant Asbestos Awareness Certificate that is valid for three years.
The health effects of asbestos exposure
Understanding what asbestos does to the body explains why even a single uncontrolled exposure is taken so seriously. When fibres are inhaled, the body cannot break them down or clear them away. They remain in the lung tissue, causing inflammation and scarring that can, decades later, develop into serious and often fatal disease.
The role of PPE and RPE
Where work near asbestos cannot be avoided, the right respiratory protection (RPE) and personal protective equipment (PPE) help reduce exposure - for example FFP3 or P3 respirators with proper face-fit, Type 5 disposable coveralls, and careful decontamination. But PPE is the last line of defence, not the first. Awareness training is clear that the safest action is not to disturb asbestos at all, and to leave removal to licensed contractors.
Latency and the importance of early awareness
Asbestos disease does not appear straight away. The long latency period - often 15 to 60 years - means today's exposure may not show up until retirement. This is why younger workers, apprentices and anyone new to the trades need awareness training early, before they ever pick up a drill in an older building. Prevention now protects health for a lifetime.
Preventing asbestos exposure
Preventing exposure follows a clear order of priority. The aim is always to keep fibres out of the air in the first place, rather than relying on protective equipment after the fact.
1. Do not disturb it
The most effective control is to leave asbestos undisturbed. If an ACM is in good condition and will not be disturbed by the work, the safest option is usually to manage it in place rather than touch it at all.
2. Identify and manage
Find out what is present through a survey and asbestos register, label or flag known ACMs, and keep a management plan that tells everyone on site where asbestos is and what condition it is in.
3. Control the work and use licensed contractors
Where asbestos must be disturbed, the work has to be properly controlled - with a written method, restricted access, and the right containment. Removal and higher-risk work must be carried out by trained or licensed asbestos contractors, never by untrained staff.
4. Train every at-risk worker
Comprehensive Asbestos Awareness Training gives workers the knowledge to recognise likely ACMs, stop before disturbance, and escalate to a competent person. While awareness training alone cannot remove all risk, it is the foundation that makes every other control work.
Asbestos and its impact in Ireland
Asbestos remains the leading cause of work-related death in Ireland, and the number of asbestos-related illnesses reflects exposures from decades ago, when the material was used heavily and its dangers were less understood. Because so many older buildings still contain ACMs, the risk has not gone away - it has simply moved from the factories that made asbestos products to the workers who maintain and refurbish the buildings that contain them.
The human cost is severe: families face the loss of loved ones to mesothelioma and other incurable conditions. For employers, failing to manage asbestos can mean HSA enforcement, prosecution and civil claims, alongside the far greater cost of harm to their people. Investing in awareness training is one of the simplest and most effective ways to protect both.
