Out of Sight but Still a Threat: Why you Can’t Afford to Ignore Hidden Foam Hazards in your Fire Safety Plan 

When it comes to fire safety, what’s out of sight is often out of mind. You know the extinguishers are serviced, the alarms are tested and the exits are clear. But what about the equipment tucked away in a vehicle locker or the obsolete foam system still quietly connected to your sprinkler line? 

As regulations around PFAS-based firefighting foam tighten across Ireland and Europe, many fire safety teams – especially in commercial and industrial sectors – are finding themselves unknowingly exposed to serious environmental and compliance risks. And the biggest threats are often hiding in plain sight. 

This isn’t the time to panic – it’s the time to prepare. Because staying compliant doesn’t start with switching products, it starts with understanding the risks already present in your system and knowing what to do next. 

The Silent Risk of Legacy Foam Stock 

If your site uses, stores, or even has a history of using AFFF (aqueous film-forming foam), you may already be at risk of falling foul of new environmental controls. These older Class B foams – widely used for tackling flammable liquid fires – typically contain PFAS, a group of chemicals now recognised for their harmful, long-lasting impact on human health and the environment. 

In 2023, the EU proposed a near-total ban on PFAS across all sectors, with firefighting foam first in the spotlight. While Ireland’s HSA is still finalising its phased response, the direction is clear – PFAS-based foams are on the way out and fast. 

But for many organisations, the problem isn’t what they’re actively using. It’s what they’ve forgotten they still have: 

• Drums of foam concentrate quietly stored in a depot. 

• Disused sprinkler systems containing legacy foam. 

• Unmarked canisters left behind by previous contractors. 

All of these pose serious risks – not just environmentally, but legally too. 

Why this Matters for Irish Businesses 

Under current Irish regulations, companies have a duty to manage all hazardous substances on site, including legacy firefighting agents. That means even if you’re not actively using PFAS-based foam, having it on-site without a disposal plan could still put you at risk of breaching environmental compliance rules. 

And it’s not just the HSA that’s watching. As local authorities and insurers tighten their policies, more organisations are being asked to account for: 

• What foam is in use across the site? 

• Where is it stored? 

• Is it PFAS-free? 

• How is it disposed of? 

Without clear records, a proactive disposal plan and professional advice, it’s easy to find yourself scrambling when an audit or inspection rolls around. 

The Cost of Doing Nothing 

If this feels like something that can wait – it isn’t. If you’re not on top of this you could find yourself struggling with: 

• Contractors refusing to work due to environmental safety concerns. 

• Storage areas being flagged during ISO audits. 

• Redundant foam stocks becoming costly to remove last-minute. 

• Rising insurance premiums due to unclear fire system specs. 

And in worst-case scenarios, unknown contamination could even result in site shutdowns, investigation orders and mammoth disposal costs. 

The truth is, ignoring legacy foam doesn’t save you money. It stacks up risk – environmental, reputational, financial and legal. 

How to Spot Hidden Foam Hazards 

Every site is different, but the following areas are worth reviewing right now: 

1. Old or infrequently used fire suppression systems. 

2. Portable foam extinguishers with no clear labelling. 

3. Unmarked or inherited foam drums. 

4. Outdated spec sheets that don’t confirm foam type. 

5. Areas where maintenance records are incomplete or missing. 

If you’re not sure what you’re looking at, don’t guess. Get a professional to audit it properly. A few hours of expert advice could save you months of clean-up and compliance fallout.

Frequently Asked Questions (FAQs) 

1. What is legacy foam and why is it a risk? 

Legacy foam refers to older firefighting foam products, often containing PFAS, that may still be stored or connected to systems on your site – even if they’re no longer actively in use. These can pose environmental, health and legal risks under new regulations. 

2. Are PFAS-based foams banned in Ireland? 

Not yet – but a phased ban is coming. The EU has proposed a near-total ban on PFAS, with firefighting foam first in line. Ireland’s Health and Safety Authority (HSA) is in the process of adapting these changes. Now is the time to get ahead of compliance. 

3. What does PFAS stand for? 

PFAS stands for per- and polyfluoroalkyl substances. These are long-lasting synthetic chemicals used in various products including firefighting foams, known for their resistance to heat, water and oil – and for their harmful environmental impact. 

4. What should I do if I think I have PFAS foam on-site? 

Don’t guess. A professional assessment can help you identify, isolate and safely remove PFAS-based foam products. Start with an inventory of all extinguishers, foam systems and stored stock and speak to a qualified fire safety partner. 

5. Is it illegal to keep PFAS foam on-site? 

Not currently – but it is your legal duty to manage and store hazardous substances responsibly. That includes keeping accurate records and having a safe disposal plan in place. Failing to do so could risk non-compliance with environmental and health and safety legislation. 

6. How do I dispose of foam concentrate safely in Ireland? 

Foam disposal must be handled by licensed waste operators and documented appropriately. Dumping or incorrect storage can lead to environmental damage, fines or legal action. Always consult with a fire safety provider familiar with Irish regulations. 

7. Can Munster Fire & Safety help with legacy foam audits? 

Yes – we offer clear, professional support to help you identify legacy foam risks and transition toward PFAS-free systems. Whether you need an audit, disposal advice or replacement options, we can guide you step by step.
