What happens when a fire safety engineer peer reviews a design?

A peer review is more than a second set of eyes.

An independent fire safety engineer reviews the proposed fire engineering approach to consider whether the assumptions, methodology, analysis and conclusions are technically appropriate and adequately supported.

Depending on the project, this may include reviewing:
• The proposed fire safety strategy and Performance Solutions
• Design assumptions and fire scenarios
• Relevant calculations, modelling and analysis
• The application of the NCC, Australian Standards and other guidance
• Whether the conclusions are supported by the evidence presented

Peer review can also help identify issues early, before they become more difficult or costly to resolve later in the design or construction process.

Importantly, the role of the peer reviewer is not to redesign the project. It is to provide an independent technical assessment of the proposed approach.

The next notable Australian fire in our series was a Sydney apartment fire in 2012.

Two young women were trapped in an illegal fourth bedroom by thick black smoke and temperatures exceeding 600°C. As firefighters arrived and horrified onlookers watched, they jumped from the window. One woman died and the other suffered serious injuries.

One significant outcome of this tragedy was the introduction of mandatory sprinkler protection in new Class 2 and Class 3 buildings of four or more storeys in the NCC 2019 Amendment 1.

A house fire in Sydney last month is a tragic reminder to ensure you have a home fire escape plan. This is especially important for those living in units that may only have one exit.

“It’s crucial that people determine their escape routes in the home now when it’s safe,” Acting FRNSW Commissioner, Michael Morris said, “Waiting until a fire breaks out to identify available exits may not be possible when smoke and flames fill the home.

Three people perished in this fire as the only exit they had was the front door, which was blocked by fire and the bedroom windows had iron bars across them.

Through our fire safety expert witness work, we've noticed the same issues arise time and again across building litigation matters.

One of the most common involves product substitution.

A specified product may become unavailable, too expensive or subject to long lead times, so an alternative product is installed instead. The problem arises when that substitution is not reviewed by the fire safety engineer or reassessed against the original fire safety strategy or Performance Solution.

Another recurring issue is undocumented design changes.

Changes during construction are common and, in many cases, unavoidable. However, if the fire engineering documentation is not updated to reflect those changes, the consequences can extend well beyond the construction phase.

We also regularly see:
• Incomplete fire engineering reports
• Poor document and version control
• Inadequate records of design decisions
• Communication breakdowns between consultants, contractors and subcontractors

These issues can remain hidden for years until they are exposed by a fire, a building defect investigation, or a regulatory audit.

When a dispute arises, the quality of the project documentation often becomes a critical factor in determining liability and understanding how decisions were made throughout the project.

Lithium-ion batteries can catch fire when NOT on charge due to internal short circuits, physical damage, or manufacturing defects. These issues trigger an uncontrolled self-heating reaction known as thermal runaway.

This thermal runaway chain reaction can begin minutes to hours before the final stage where we see fire and explosions. Before the thermal runaway is the venting stage where toxic gases are released.

This article describes an event in WA where a drill battery, that was not left on charge, resulted in a house being burned to the ground.
https://www.nine.com.au/australia-news/a-current-affair/while-on-holiday-in-bali-paul-got-the-call-that-his-home-had-burnt-to-the-ground-20260721-p60hbh.html

It is reported that firefighters in WA respond to three lithium-ion battery fires a week.

It is fine to advise the public to store rechargeable devices in a separate area and away from soft furnishings and other materials that can catch fire … but is this advice practical?

The toys our children play and sleep are often rechargeable. We don’t have the space to store our rechargeable vacuum cleaner in a room by itself.

So how do we protect ourselves from this hidden, silent threat?

At the very least, it is imperative that you have smoke alarms installed in your home, a personal evacuation plan and awareness of what rechargeable batteries and devices are in your home and where they are being kept.

Always call Triple Zero (000) immediately if there is fire or smoke.

Both passive and active fire protection systems play a critical role in protecting lives and property during a fire.

Passive fire protection is built into the structure of a building. It helps contain fire and smoke, protects the building's structural stability, and provides occupants with time to safely evacuate.

These systems are often hidden within the building and may not be immediately visible. Examples include fire-rated ceilings, walls and floors, fire doors, fire stopping around service penetrations, structural fire protection.

Active fire protection systems are designed to detect, alert, control or suppress a fire. These systems require activation, either automatically or manually.

These are the fire safety measures most people are familiar with. Examples include fire detection and alarm systems, automatic fire sprinkler systems, fire hydrants, hose reels and fire extinguishers.

Neither system works in isolation. A well-designed building relies on passive and active fire protection working together to achieve the required level of fire safety.

Understanding the difference is fundamental for anyone involved in the design, construction, maintenance or management of buildings.

A building can be compliant when it's completed - but is it still performing as originally designed years later?

A fire safety performance gap can develop when building alterations, maintenance or renovations change the way fire safety systems perform without considering the original fire engineering design.

Passive fire protection can be unintentionally compromised through unsealed or inadequately fire-stopped penetrations. A common example occurs in residential top-floor apartments that rely on fire-rated ceiling systems to provide the required fire separation between the apartments and the roof space.

These ceilings are not simply an architectural finish—they are an integral part of the building's fire safety strategy, designed to prevent a fire in one apartment from spreading through the roof space to the other apartments.

Problems arise when owners or contractors install downlights, exhaust fans, air-conditioning units or other services without appropriately fire-stopping the new penetrations. Although these alterations may appear minor, they can significantly reduce the fire-resistance performance of the ceiling system.

Similarly, fire doors are designed to contain a fire within an apartment and prevent it from spreading into the common hallway, protecting occupants as they evacuate and limiting fire spread throughout the building. Altering a fire door, for example by trimming it, replacing hardware, drilling holes, installing pet doors or changing seals, can compromise its fire-resistance performance and prevent it from functioning as intended during a fire.

In many cases, the underlying issue is not poor workmanship alone, but a lack of awareness. If the fire safety function of a building element is not clearly communicated during handover, future owners, occupants and contractors may unknowingly compromise the building's fire safety.

Do you know what fire safety systems are in your building?

On 18 November 2011, firefighters responded to an automatic fire alarm at the Quakers Hill Nursing Home in Sydney. There were many challenges for the firefighters, including dense smoke resulting in zero visibility. Despite the extraordinary efforts of emergency responders and staff, of the 88 elderly residents, 11 lost their lives.

At the time, nursing homes were not required to have an automatic fire sprinkler system. This tragedy changed Australian fire safety laws.
