Essential Fire Safety Guide: Smoke Alarms, Carbon Monoxide Detectors, Escape Routes & Irish Regulations
Introduction
Fire safety is a non‑negotiable part of owning, renting or managing a property in Ireland. Recent updates – the 2024 Building Regulations, the new Irish Standard I.S. 3218:2024 for fire detection, and stricter landlord obligations under the Residential Tenancies Board (RTB) – mean that both homeowners and landlords must be more vigilant than ever. This guide consolidates the latest legal requirements with practical, step‑by‑step advice so you can protect lives, avoid costly fines, and keep your property compliant.
1. Smoke Alarms – What the Law Requires and How to Choose the Right Ones
1.1 Legal requirements (2024)
| Property type | Minimum alarm type | Placement | Maintenance |
|---|---|---|---|
| Dwelling houses (new builds) | Battery‑operated or mains‑powered smoke alarm complying with EN 14604 | Every bedroom, living room, hallway leading to bedrooms, and any separate kitchen | Replace batteries annually (or every 10 years for sealed units). Test monthly. |
| Rental properties (RTB minimum standards) | Same as above plus interconnected alarms where possible | As above, plus any additional sleeping areas or loft conversions | Landlords must ensure working condition at the start of tenancy and provide a written instruction sheet. |
| Multi‑unit buildings (apartments, blocks) | Interconnected smoke alarm system with a central control panel (addressable or conventional) | One alarm per bedroom, per living area, and in corridors serving two or more units | Annual inspection by a qualified fire engineer; records must be kept for at least 5 years. |

1.2 Choosing the right alarm
- Photoelectric vs. Ionisation – Photoelectric detectors are more effective for smouldering fires (common in homes). Choose dual‑sensor units for broader coverage.
- Interconnectivity – For new builds, linking alarms ensures the whole house sounds when any detector triggers. Wireless kits are available for retrofits.
- Power source – Hard‑wired units with battery backup are preferred in new builds; battery‑only units are acceptable in existing dwellings.
- Certification – Look for the Irish Standard I.S. 3218:2024 mark or CE marking referencing EN 14604.
1.3 Installation checklist
- Install at least 1 m from the ceiling to avoid dead‑air zones.
- Keep at least 50 cm from cooking appliances to reduce false alarms.
- Avoid placement in high‑humidity rooms (e.g., bathrooms) unless the alarm is rated for such environments.
- Test each alarm using the “test” button after installation and every month thereafter.
- Record the installation date, model, and maintenance schedule in a property file.
2. Carbon Monoxide (CO) Detectors – Protecting Against the Invisible Threat
2.1 Why CO detectors matter
Carbon monoxide is colourless, odourless and can be lethal at concentrations as low as 50 ppm after 2 hours of exposure. The most common sources are faulty gas boilers, unvented heaters, and blocked chimneys. Ireland recorded ≈ 150 CO‑related hospital admissions in 2023, with a fatality rate of 0.02 % (Health Service Executive data).
2.2 Legal framework
| Situation | Requirement |
|---|---|
| All residential properties with gas or solid‑fuel appliances | At least one CO detector complying with EN 50291 (or I.S. 3218:2024) installed in a room containing the fuel‑burning appliance. |
| Rental units | Landlords must provide a working CO detector, include it in the inventory, and replace it every 5 years or per manufacturer’s guidance. |
| New builds (post‑2022) | Detectors must be hard‑wired with battery backup where permanent gas appliances are present. |

2.3 Best practice for placement
- Install outside the living area where the appliance is located, at least 1 m from the ceiling and 1 m from the floor.
- Do not install directly above or beside a fuel‑burning appliance; maintain a minimum 30 cm gap.
- In homes with multiple gas appliances, consider a single detector per floor or a networked system that alerts all zones.
2.4 Maintenance routine
- Test the alarm monthly using the test button.
- Replace batteries every year (or as indicated by the device’s low‑battery signal).
- Keep a log of installation date and replace the unit every 5 years.
3. Planning and Maintaining Escape Routes
3.1 Core regulatory points
- Fire Services Act 1981 (as amended 2018) obliges property owners to provide “reasonable means of escape”.
- Building Regulations Part B (2024) require clear, illuminated escape routes and emergency lighting for all premises where a fire alarm is installed.
- RTB Minimum Standards demand that rental properties have unobstructed egress, functional fire doors, and clearly marked exit signs.
3.2 Designing an effective escape plan
| Element | Practical guidance |
|---|---|
| Number of exits | Minimum two separate escape routes from any sleeping area. Larger homes may need three. |
| Route width | Minimum 900 mm clear width for corridors and stairwells. |
| Fire doors | Must be self‑closing, intumescent‑sealed, and unlocked on the exit side. Test door integrity annually. |
| Signage | Use green “running man” signs with illuminated or photoluminescent backing. Position signs at each door and major junction. |
| Emergency lighting | Battery‑backed lighting covering at least 90 % of the escape route length, with a minimum 1 lux illumination at floor level. |
| Assembly point | Designate a safe area at least 30 m from the building, away from potential fire spread. Communicate this to all occupants. |
3.3 Routine checks
- Monthly walk‑through – Verify that corridors, stairwells and doors are free of obstacles (e.g., boxes, furniture).
- Quarterly fire door test – Ensure the door closes fully and the latch engages without force.
- Annual emergency lighting test – Verify battery backup lasts the required 90 minutes.
- Update the fire evacuation plan whenever the layout changes (new furniture, renovations, added rooms).
4. Fire Safety Regulations – A 2024‑25 Overview
| Regulation | Key points for homeowners & landlords |
|---|---|
| Fire Services Act 1981 (as amended 2018) | General duty to take “all reasonable measures” to prevent fire and ensure safe evacuation. |

| I.S. 3218:2024 – Fire Detection & Alarms | Introduces addressable alarm panels, mandatory system commissioning certificates, and a 10‑year maintenance schedule. |
| Safety, Health and Welfare at Work Act 2005 | Requires employers (including landlords who operate as “employers” of staff/contractors) to carry out fire risk assessments. |
| RTB Minimum Standards (2024) | Specific obligations for rental properties: working smoke & CO alarms, functional fire doors, clear egress, and provision of fire safety information to tenants. |
| National Standards Authority of Ireland (NSAI) – Certification | New installations must be certified by a registered fire alarm contractor and a fire safety certificate must be retained for the life of the system. |
4.1 Penalties for non‑compliance

5. Practical Checklist for Property Owners
| Task | Frequency | Who is responsible |
|---|---|---|
| Install & test smoke alarms (per room) | At hand‑over & monthly test | Landlord / Homeowner |
| Install & test CO detectors | At hand‑over & monthly test | Landlord / Homeowner |
| Fire risk assessment (professional) | Every 3 years or after major change | Qualified fire risk assessor |
| Verify fire doors & signage | Quarterly visual check | Property manager |
| Emergency lighting test | Annually (full battery discharge) | Qualified electrician |
| Update fire evacuation plan | After any layout change | Landlord / Homeowner |
| Keep records (certificates, test logs) | Ongoing, retain ≥ 5 years | Landlord / Homeowner |
| Provide tenants with safety information pack | At tenancy start | Landlord |
6. Tips for Tenants – What to Look For
- Ask for the fire safety information pack – It should list alarm locations, CO detector locations, escape routes, and fire extinguisher locations.
- Test alarms – Press the test button; if you hear a clear tone, the alarm works.
- Check battery dates – Replace any dead batteries immediately and inform the landlord.
- Know two escape routes – Walk the route from each bedroom to the outside.
- Report defects – Any blocked exit, non‑functioning alarm, or missing CO detector must be reported in writing.
