Australia has experienced a surge in the adoption of lithium-ion battery technology in recent times, and QLD is no exception. These small, lightweight, and versatile batteries have revolutionized various aspects of modern life, powering everything from smartphones to e-scooters, e-bikes, and home renewable energy storage systems. However, this remarkable advancement is accompanied by a concerning increase in lithium-ion battery fires in homes across Queensland.

QLD Lithium-Ion Battery Fires Increasing Significantly

Data compiled from each Australian state fire department reveals that since 2021, more than 450 fires related to lithium-ion batteries have occurred in Australia, with 157 of them in Queensland alone. Improper battery charging practices have been identified as one of the primary causes behind these alarming incidents. When consumers use incompatible battery chargers or leave their electronic devices, like e-scooters, charging unattended for extended periods, overcharging and overheating of the lithium-ion battery can occur.

What Causes Lithium-Ion Battery Fires?

Another significant cause of lithium-ion battery fires is manufacturing defects in either the battery charger or the battery itself. Poor quality control during production can lead to internal faults, increasing the risk of overheating and fire. Additionally, improper storage or transportation of lithium-ion batteries can cause short circuits and subsequent fires. To minimize this risk, it is crucial to avoid purchasing cheap lithium-ion batteries and chargers from unregulated online marketplaces and to opt for original equipment manufacturer (OEM) products.

The nature of use for e-scooters and e-bikes exposes their batteries to rough handling and environmental elements, making them susceptible to damage that can result in internal short-circuits and fires. Even minor physical damage to the battery’s protective casing can create a pathway for ‘thermal runaway’, triggering a catastrophic fire event. When lithium-ion batteries fail, they undergo thermal runaway, leading to the violent bursting of battery cells, the release of toxic, flammable, and explosive gases, and an intense, self-sustaining fire. These fires are challenging to extinguish with water or regular fire extinguishers, and they can easily reignite after being put out.

Are The Lithium Batteries Dangerous In My

Interconnected Smoke Alarm?

This is a good question and one that needs to be asked. It would be ironic if smoke alarms designed to detect smoke and save lives were actually powered by lithium-ion batteries that are a major cause of house fires! Fortunately the same fire risk in lithium-ion batteries is not present in the 10-year lithium batteries sealed inside your interconnected smoke alarms. Why? The two small, 3V lithium batteries inside your smoke alarm are non-replaceable and non-rechargeable and are designed to deplete slowly and steadily over a 10-year lifespan. They do not undergo the repeated energy discharge / recharging process that much larger lithium-ion batteries do, and are not subjected to the same external forces of bumping, knocking and damage that scooters, e-bikes and other devices experience – this eliminates the associated fire and thermal runaway risk. Additionally, all interconnected smoke alarms sold in Australia should comply with Australian Standard 3786:2014 which incorporates stringent electrical testing of the smoke alarm itself, prior to sale.

Interconnected Smoke Alarm Battery Safety

It is essential that all interconnected smoke alarms purchased are certified to Australian Standard 3786:2014 and bear the official Australian Standard mark and the Regulatory Compliance Mark (RCM). The RCM signifies compliance with Australian electrical safety and electromagnetic compatibility regulations, as outlined in Australian Standard 3820:2020. By avoiding cheap knock-offs lacking these marks, consumers can ensure they are purchasing legitimate, safe electrical appliances.

Top Tips For Preventing Lithium-Ion Battery Fires

  1. Use Manufacturer-Approved Chargers:
    • Always use the charger and power adapter that comes with your device or is recommended by the manufacturer.
  2. Monitor Charging:
    • Charge batteries in a place where you can keep an eye on them and avoid charging overnight or when you’re not at home.
  3. Avoid Overcharging:
    • Unplug devices once they are fully charged to prevent overheating and reduce wear on the battery.
  4. Store Batteries Safely:
    • Keep batteries in a cool, dry place, away from direct sunlight and flammable materials.
  5. Avoid Physical Damage:
    • Handle batteries with care to prevent drops, punctures, or any form of physical damage that could lead to internal short circuits.
  6. Check for Damage:
    • Regularly inspect batteries for signs of damage, swelling, or leakage. Stop using and properly dispose of any damaged batteries. This is particularly important for any transportation or mobility devices such as e-bikes or e-scooters.
  7. Keep Away from Extreme Temperatures:
    • Avoid exposing batteries to high or low temperatures, which can cause damage and increase the risk of fire.
  8. Don’t Mix Batteries:
    • Do not use old and new batteries, or batteries of different types and capacities, together in the same device.
  9. Proper Disposal:
    • Do not throw lithium-ion batteries in the regular wheelie bin to prevent potential fires. Ensure that you tape the terminals of used batteries with clear sticky tape before taking them to your local Council’s drop off point / recovery centre.
  10. Install Interconnected Smoke Alarms:

Summary

The increase in lithium-ion battery fires necessitates a collaborative effort from manufacturers, regulators, and users to address this growing concern. While the advantages of lithium-ion batteries are undeniable, safety risks demand immediate attention. By enhancing safety regulations, improving manufacturing standards, and promoting responsible usage and recharging practices, Australia can fully embrace the lithium-ion battery revolution while ensuring a safer and more sustainable future for all.

ZEN Interconnected Smoke Alarms

New Farm, QLD, 4005

A fatal caravan fire in QLD last year has again sparked demands for a comprehensive review of Queensland’s smoke alarm laws for caravans and moveable dwellings. Emergency response teams were dispatched to the blaze in Upper Brookfield, located in the western suburbs of Brisbane, during the early hours of Saturday 20th May 2023. Upon arrival, firefighters encountered flames engulfing the van from all sides and tragically two people were discovered deceased inside the wreckage. This is not the first fatal caravan fire to occur in QLD.

ABC news story aired May 2023 – QLD smoke alarm laws have since been updated July 2024

Caravan Smoke Alarm Laws Updated In QLD

Our previous blog post published only a few months ago identified caravan smoke alarm laws for each state. At that time Queensland was one of only three states in Australia where although ‘recommended’ by the QLD Fire Department, compulsory smoke alarms were not mandated by law in caravans, campervans and other such moveable dwellings. This has since changed with the revised QLD Fire Services Act 1990, which now legally mandates compulsory smoke alarm requirements for all QLD registered caravans and motorhomes from 1st July 2024.

As reported by Queensland’s Courier Mail newspaper at that time;
‘Queensland Fire and Emergency Service officials are working on potential amendments to smoke alarm legislation for movable dwellings “The work is complex and requires further consultation with stakeholders,” a QFES spokesman said.


Fire and Emergency Services Minister Mark Ryan said: “We take advice from the experts on matters like this, and I have asked Queensland Fire and Emergency Services to expedite its consideration of this matter”. “QFES is preparing advice for the government about this issue,” he said. “We are always looking at ways to support community safety.”


“If there is more that can be done to support safety in relation to caravans and other mobile types of accommodation, the government will always give that careful consideration.”

Caravan fires have been a recurring concern over the years, with some distressing incidents occurring within Queensland. In 2022 a young father in Logan tragically died whilst protecting his partner and unborn child from a caravan fire which started due to a combusting e-scooter battery.
NSW laws have required that smoke alarms be installed in all new and existing moveable dwellings since 2011. The Brisbane Times magazine reported back in 2020 that a Queensland deputy coroner called for the state’s fire service to consider the mandatory installation of smoke alarms in all moveable dwellings after an army veteran died in a caravan park blaze near Lowood, west of Brisbane.

Postscript Update – New QLD Laws Introduced July 2024

Following this devastating caravan fire incident in Upper Brookfield, smoke alarms laws were updated in QLD to include caravans and motorhomes.

From 1 July 2024, all QLD registered caravans or motorhomes whose registration is commencing or being transferred must have an Australian Standard 3786:2014 compliant photoelectric smoke alarm installed on the ceiling that is compliant with Australian Standard 3786:2014. From 1 July 2027, all other registered caravans and motorhomes must have a photoelectric smoke alarm installed. The photoelectric smoke alarm must be powered by a 10-year non-removable battery. Failure to comply with the requirements is an offence with a maximum penalty of five (5) penalty units (currently $774).

Smoke Alarms In QLD Caravans – Conclusion

Don’t allow yourself to become a statistic. Heed the new caravan smoke alarm laws in Queensland. If you own a caravan, campervan or other moveable home please be pro-active and make sure you have at least one working ZEN photoelectric smoke alarm and fire blanket installed today.

Queensland Smoke Alarm Legislation

The two key pieces of QLD smoke alarm legislation are called the;

  • Fire Services Act 1990 (previously named the Fire and Emergency Services Act 1990)
  • Building Fire Safety Regulation 2008

The goal of the legislation is to reduce loss of life by ensuring that all fire safety installations (including photoelectric interconnected smoke alarms) within a domestic building are adequately maintained.

Building Fire Safety Regulations 2008 – Smoke Alarms

Part 5A of the QLD Building Fire Safety Regulation 2008 deals with photoelectric smoke alarm requirements for domestic dwellings. It states that smoke alarms must;

  • Comply with the Australian Standard (AS 3786:2014).
  • Contain a photoelectric sensor, and not also contain an ionization sensor.
  • Be hardwired into a building’s power supply or powered by a non-removable minimum 10-year lifespan battery.

Where Smoke Alarms Must Be Installed

Part 5A also states exactly where smoke alarms must be installed inside a domestic dwelling (the prescribed locations). It says that photoelectric smoke alarms must be installed in;

  • each bedroom.
  • the hallway which connects each bedroom.
  • if there is no hallway connecting each bedroom, then a part of the storey that is between the
    bedroom and the rest of the dwelling.
  • for each storey with no bedrooms—on the most likely travel path of exit from the dwelling.

Where Smoke Alarms Must Not Be Installed

Part 5A (3) also provides exact distances and measurements where smoke alarms should / should not be installed. It states that smoke alarms must not be installed;

  • within 300mm of a light fitting.
  • within 300mm of a corner of the ceiling and a wall.
  • within 400mm of an opening from which air is supplied from an air conditioner or forced air vent.
  • within 400mm of the blades of a ceiling fan.

Fire Services Act 1990 – Smoke Alarms

The QLD Fire Services Act 1990 says that from 1st January 2022 all rental properties and properties being sold or substantially renovated in QLD must have smoke alarms which;

  • Are less than 10 years old
  • Be interconnected with every other smoke alarm in the building so that all activate together
  • Operate when function tested

If the smoke alarm being replaced was hardwired to the domestic dwelling’s electricity supply, the replacement smoke alarm must also be hardwired to the dwelling’s electricity supply. Any newly constructed homes or substantial renovations must have photoelectric interconnected smoke alarms which are hardwired to the mains power supply. A definition of a ‘substantial renovation’ is provided on pages 90 of the Act.

Additionally, these requirements will become mandatory for ALL dwellings in Queensland by 1st January 2027.

Interconnected Smoke Alarms In QLD Rental Properties

With respect to QLD rental properties, the Act also requires that;

  • The lessor must test each interconnected smoke alarm within 30 days before the start of a tenancy in a domestic dwelling.
  • The tenant must test all interconnected smoke alarms in the dwelling at least once every 12 months.
  • If the tenant is aware a smoke alarm in the dwelling has failed, the tenant must advise the lessor as soon as practicable.
  • The tenant must clean all interconnected smoke alarms at least once every 12 months.

Environmental Planning and Assessment Amendment

(Smoke Alarms) Regulations 2006

On 1 May 2006, the New South Wales Government introduced new legislation following a series of deadly house fires. Division 7A of the NSW Environmental planning and Assessment Amendment (Smoke Alarms) Regulation 2006 calls out minimum requirements for smoke alarm installation in existing residential dwellings.

The NSW Environmental Planning and Assessment Amendment (Smoke Alarms) Regulation 2006 says that;

– Smoke alarms must comply to Australian Standard 3786:2014 and can be powered either by a 10-year non-removeable battery, or hard wired to the mains electricity supply.

– A minimum of one working smoke alarm should be installed on every level of a dwelling (even if there are no bedrooms on that level).

NSW interconnected smoke alarms – best practice

Whilst this is the minimum standard required by NSW law, Fire and Rescue NSW recommend best practice by installing photoelectric interconnected smoke alarms in all bedrooms and living spaces (including hallways and stairways) on every level of the property.

Residential Tenancies Regulation 2019

A new section (64A) relating to smoke alarms has also been added to the NSW Residential Tenancies Act 2010. This new section came into effect on March 2020 and placed extra obligations for smoke alarms on both landlords and tenants, in accordance with the NSW Rental Tenancies Regulation 2019.

NSW smoke alarm requirements for landlords

  • Ensure smoke alarms are installed as per NSW Environmental Planning and Assessment Regulations.
  • Conduct annual checks to ensure all smoke alarms are functioning.
  • Replace a smoke alarm within 2 business days of becoming aware that the smoke alarm is not working.
  • Engage a licensed electrician to repair or replace a 240V hardwired smoke alarm.
  • Replace removeable batteries in smoke alarms every year.

NSW smoke alarm requirements for tenants

  • Inform the landlord if a repair or a replacement of a smoke alarm is required, including replacing a battery.
  • Only replace a battery in a battery-operated smoke alarm, or a back-up battery in a hardwired smoke alarm, if the smoke alarm has a removable battery.
  • Give the landlord written notice, as soon as practicable if they will perform a smoke alarm repair or replacement, or engage a person to carry out a repair or replacement.

Both landlord and tenant must not remove or interfere with the operation of a smoke alarm installed on the residential premises unless they have a reasonable excuse to do so.

Smoke Alarm Laws In Western Australia

Smoke alarm laws in Western Australia are derived from the;

W.A Building Regulations 2012 (division 3) which enshrine Building Code of Australia smoke alarm requirements.

W.A Building Regulations 2012 – Smoke Alarms

In 1997, 240V hardwired smoke alarms became compulsory in Western Australia for all newly constructed residential buildings (or residential building extensions). From 2009 onwards this was extended to also include all existing residential buildings, prior to their transfer of ownership, rent or hire.

In Western Australia smoke alarms must;

  • be positioned according to the requirements of the Building Code of Australia
  • comply with Australian Standard 3786:2014
  • be permanently connected to consumer mains power (i.e. 240V hardwired)
  • be interconnected, if your home was newly built after the 1 May 2015.
  • be less than 10 years from the date of manufacture

Can I Use 10-Yr Battery Smoke Alarms In Western Australia?

YES you can! – W.A Building Regulations 2012 allow the use of 10 year non-replaceable battery powered smoke alarms in certain situations. This may include where mains power is not connected to the building, there is no hidden space to run the necessary wiring for mains powered alarms, and there is no appropriate alternative location – for example, where there is a solid concrete ceiling. It should be noted that formal approval must be obtained by the local council to use 10 year non-replaceable battery powered smoke alarms in these situations.

Just like all other Australian states and territories, it is mandatory in South Australia for working Australian Standard 3786 compliant smoke alarms to be fitted into every residential home. Fines can be imposed if alarms are not installed, and in rental properties the onus is on landlords to ensure the smoke alarms are working.

Smoke Alarm Laws In South Australia

The governing legislation for smoke alarms in South Australia is the Planning Development and Infrastructure (General) Regulations 2017.

The Planning and Development Infrastructure (General) Regulations 2017 call out minimum requirements for smoke alarms in dwellings. To summarise, they state that smoke alarms must comply with the Building Code of Australia (BCA);

Smoke Alarms In Existing Homes Or Residential Properties Built Prior To 1 Jan 1995

A battery powered smoke alarm may be installed in these premises subject to any change of ownership conditions.

When an existing house built prior to 1995 is sold, the owner then has 6 months from the date of title transfer to install photoelectric smoke alarms which are either 240V hardwired or have a 10 year life non-removeable lithium battery.

Smoke Alarms In New Houses Or Residential Properties Built After 1 Jan 1995

The Building Code of Australia requires 240V mains powered photoelectric smoke alarms.

Northern Territory Smoke Alarm Legislation

The governing piece of smoke alarm legislation in the Northern Territory is called the Northern Territory Fire and Emergency Regulations 1996 (as in force 1 October 2019).

N.T Fire and Emergency Regulations 1996 – Smoke Alarms

Part 2A of this regulation details requirements relating to smoke alarms, notably to do with the type of alarm, installation, maintenance and testing. A summary is provided below;

  • All owners of residential property must have working smoke alarms installed and tested annually.
  • Any existing ionization alarms must be replaced with the photoelectric type when they no longer work, the property is sold, or premises are rented out or a lease is renewed.
  • Within 30 days before the start of a tenancy agreement in relation to residential premises or a moveable dwelling, the owner of the premises or dwelling must test the smoke alarms and replace any that do not function.
  • The responsibility for testing the fire alarm in a tenanted property lies with the tenant (after the lease has started). The tenant must advise the owner or agent if the fire alarm does not work.

Section 13A (3) of the regulation states that an approved smoke alarm means a photoelectric type that:

(a) complies with Australian Standard 3786 and;

(b) is hard wired or is a sealed 10-year lithium battery smoke alarm.

Where Do I Install Smoke Alarms In The Northern Territory?

The N.T regulations state that smoke alarms must be installed in residential premises according to the Building Code of Australia, section 3.7.2.3. What this means is that smoke alarms in the Northern Territory must be installed;

  • on or near the ceiling in any storey containing bedrooms
  • between each part of the dwelling containing bedrooms and the remainder of the dwelling; and
  • where bedrooms are served by a hallway, in that hallway; and
  • any other storey not containing bedrooms.

Interconnected Smoke Alarms

And Australian Standard 3786:2014

Before buying an interconnected smoke alarm you should do your due diligence to ensure it is compliant to Australian Standard 3786:2014. The full name of the standard which encompasses smoke alarms in Australia is ‘Australian Standard 3786:2014 Smoke alarms using scattered light, transmitted light or ionization’ (incorporating amendment 1 and 2). This article will review Australian Standard 3786:2014 to assist your purchasing decision.

Standards are documents that set out specifications, procedures and guidelines to ensure products are safe, consistent, and reliable. Australian Standard 3786:2014 is referenced by QLD’s Building Fire Safety Regulations 2008 – when a standard is referenced by state or national legislation, compliance with it becomes mandatory. It is interesting to note that although there is a newer Australian Standard 3786:2023 – it is not yet referenced by legislation – therefore Australian Standard 3786:2014 must still be complied with in the eyes of the law.

Australian Standard 3786:2023

Australian Standard 3786:2014 is divided into several key components – the area of interest that will be reviewed today is section 4.17 – ‘general requirements’.

Section 4.17 of the Australian Standard states that; ‘The smoke alarm shall be so designed that a sphere of diameter larger than 1.3 ±0.05 mm cannot pass into the sensor chamber(s)’. This requirement is intended to restrict the access of foreign bodies such as insects into the sensitive parts of the smoke alarm (to prevent nuisance alarms). It is known that this requirement is not sufficient to prevent the access of all insects; however, it is considered that extreme restrictions on the size of the access holes may introduce the danger of clogging by dust, etc.

Interconnected Smoke Alarms – Mesh Screen

How does this requirement translate into the design and manufacture of your photoelectric interconnected smoke alarm? The image below shows the compliant internal component from our ZEN wireless interconnected smoke alarm. The polymer mesh surrounding the sensitive photoelectric chamber within the alarm contains thousands of tiny holes, each perfectly engineered, no larger than 1.3mm in diameter. The tiny holes prevent insects from accessing the internal chamber whilst still allowing air (and smoke) to pass through.

Mesh screen surrounding the photoelectric smoke alarm internal sensor chamber

As per Australian Standard 3786:2014 – holes are no larger than 1.3mm diameter

In addition to this internal mesh screen around the perimeter of the photoelectric chamber, ZEN wireless photoelectric interconnected smoke alarms also have an external housing which forms part of the of the smoke alarm itself. The external housing prevents larger foreign bodies from entering the alarm itself. Foreign bodies (i.e., insects, small house geckos) are a common cause of false / nuisance alarms because they can enter the sensitive internal components and disrupt the photoelectric light beam.

We hope you have enjoyed this review of section 4.17 of Australian Standard 3786:2014, and how it translates to the design of your interconnected smoke alarm. Whilst many smoke alarm retailers might profess to be aware of the standard, very few can claim to have read it from cover to cover or have a genuine understanding of what it means.
