You may be surprised at the number of lithium-ion batteries you have in your household and how these can attribute to the increased risk of fire within your dwelling.
Not just found in EVs, the batteries are in everything from power tools, to laptops, to e-bikes and phones.
The increased use of the batteries has led to battery-related fires in New Zealand more than doubling since 2020, according to Fire & Emergency NZ (FENZ).
Insurers have therefore reported a 17% rise in battery related claims, with mishandling during charging and disposal as the primary causes.
So, what are the key things you need to know and how can you protect yourself and your property from this potential hazard?
Understanding the key risks
- Generally speaking, lithium-ion batteries are safe as long as they are used correctly. The main reasons they catch fire are -
- Not having used the correct charger.
- Damage to the device – such as it being punctured or dropped.
- Overcharging the battery, which can then cause overheating.
- Exposure to high temperatures.
- EV battery fires in particular are hard to extinguish and may easily reignite.
- Not only do the fires spread rapidly but they cause toxic smoke, which can spread far and wide in your neighbourhood.
- Due to their explosive nature, there is a serious risk to life and/or injury not just within your premise but also to neighbouring properties.
Domestic dwellings
Based on these risks, we encourage property owners to:
- Identify where batteries are used, charged, and stored and ensure you have smoke detectors in these areas.
- Ensure all battery chargers meet New Zealand electrical safety standards and use the right charger with the right device.
- Don’t leave batteries charging over night or unattended for extended periods.
- Ensure that you regularly inspect batteries for damage, swelling, or leaks.
- Dispose of old batteries correctly. Do NOT put them in your rubbish bin as this has caused multiple rubbish truck fires. Batteries can be taken to proper recycling centres or collection points.
Body corporates
If you live within a body corporate there are some additional things to consider –
- Ensure there is a policy for the safe charging and parking of EVs, e-bikes, and other equipment within the building. For example, you should designate where charging is allowed and prohibit it in areas such as near exits or in common hallways.
- Educate residents on safe charging, why it is important, and the related emergency procedures should there be a fire.
- Within your designated charging areas, such as carparks or basements, check there are proper ventilation and fire suppression systems that provide extra fire protection.
Prevent fire in your property
Proactive management and understanding the risks posed by lithium-ion batteries, will help reduce the chance of fire, protect lives, and safeguard your property.
