April is finally here, and with it comes that urge for a fresh start. As we dive into spring cleaning and shake off the winter blues, many of us decide that it’s time to start renovating. Whether you’re knocking down walls for an open-plan layout or finally tackling that loft conversion, this season of renewal is the perfect time to transform your living space. However, with the excitement of a spring transformation, fire safety is often overlooked.
Construction work introduces new hazards into your living environment and can compromise your existing safety systems. To help you protect your home and your family, we’ve put together a comprehensive guide on managing fire risks before, during, and after your project.
Why Renovating Increases Fire Risk
A building site, even a small-scale residential one, is inherently riskier than a finished home. Renovations increase fire risk because:
- Structural Vulnerability: Stripping back walls or removing doors can remove fire breaks that usually slow the spread of smoke and flames.
- Exposed Utilities: Live wiring and gas pipes are often exposed or moved during the process.
- Combustible Materials: Piles of timber, packaging, and insulation act as fuel if a spark occurs.
- Dust Interference: Dust is the enemy of fire detection. It can settle inside smoke alarms, causing false alarms or, worse, preventing the sensor from detecting real smoke.
Common Fire Risks During Renovations
Understanding the specific hazards can help you mitigate them before they lead to an emergency.
- Hot Works: This includes soldering pipes or grinding metal.
- Electrical Overload: Using multiple high-power tools on extension leads can overload circuits.
- Blocked Escape Routes: Building materials or skips can inadvertently block exits, making it difficult to evacuate in an emergency.
- Accumulated Waste: Sawdust and oily rags are highly flammable and can even self-combust under specific conditions.
How to Safely Work with Contractors
- The Pre-Start Briefing: Before work begins, walk the site with your contractor. Point out where your current alarms are located.
- Alarm Protection: Ensure contractors know never to paint over alarms or remove batteries to stop nuisance alarms caused by dust. Instead, provide them with temporary dust covers.
- Daily Tidy-Up: Insist that the site is cleared of flammable waste at the end of every working day.
Post-Renovation Checks to “Sign Off” the Project
Once the builders have left, it is vital to ensure your fire detection system is still fit for purpose.
- Repositioning: If you have moved walls or extended a room, your old alarm positions may no longer be compliant.
- The “Dust Clean”: Even if you covered your alarms, fine dust can linger. Vacuum around the vents of your alarms to ensure the sensors are clear.
- The Test Run: Press the test button on every alarm in the house to ensure the system is still interconnected.
- Update Your Tech: If you’ve added a new kitchen, consider adding a heat alarm, which is designed to detect fire without being triggered by cooking fumes.
Renovation Fire Safety Checklist
Before Work Starts
- Notify your home insurance provider about the works.
- Check the “replace by” dates on all existing alarms.
- Identify if new rooms (like a loft conversion) require additional smoke alarms.
- Purchase dust covers for all existing sensors.
During the Project
- Keep all escape routes and hallways clear of debris.
- Check that alarms are covered during the day but uncovered at night if you are still living in the property.
- Ensure all power tools are unplugged at the end of the day.
After Completion
- Remove all temporary dust covers.
- Vacuum all alarm units to remove construction debris.
- Test the entire system to ensure interconnection is working.
- Ensure your system is still compliant with legislation.
Renovation Fire Safety FAQs
Should I take my smoke alarms down while the builders are in?
No. You should never leave a home without detection, especially when the risk of fire is higher. Use temporary dust covers during the day and remove them once the dust has settled in the evening.
The builders are moving a wall. Do I need to move my alarm?
Likely, yes. If the dimensions of the room change or any fuel-burning appliance is moved, consult a professional to ensure your alarms are still in the optimal position.
Will the dust from sanding ruin my alarms?
While a number of Aico alarms feature automatic dust compensation to prevent false triggers, excessive construction dust can eventually overwhelm the sensor. If your alarm chirps and flashes yellow four times during a test, it has reached its maximum contamination limit and requires maintenance. To protect your devices during renovations, vacuum the side vents with a narrow nozzle and wipe the cover with a damp, lint-free cloth – avoiding all chemical cleaners or aerosols. For heavy dust events, you can reset the compensation sensor by disconnecting the unit for five minutes and reinstalling it once the air is clear.
Because internal dust buildup is considered “normal wear and tear” and isn’t covered by your guarantee, it is always best to cover alarms during the renovations.
What is the best alarm for a new kitchen extension?
For kitchens, you should always use a heat alarm. These trigger based on heat alone and will not be affected by cooking fumes or steam.
