Protection of mobile machinery from hydrocarbon fuel fires
Foam systems activate automatically on detection, blanketing the fuel surface to smother vapours and starve the fire of oxygen while cooling the fuel and surrounding structures to reduce re-ignition risk.
Designed to suit both manned and autonomous vehicles or applications
Comprehensive fire suppressing agents with advanced agent (for extreme cold temperature), fluorine-free and C6 purity AFFF foam options
Single, dual or triple agent system options available when used in conjunction with Muster aerosol and/or powder systems
Cylinder options cater to various needs, including lay-flat designs for small machines with limited installation space.
Muster offers two different fire detection methods: Linear Heat Detection (LHD) and Loss of Pressure (LOP). LHD is an electrically controlled system, while LOP operates mechanically. Both systems are designed to provide early fire detection followed by activation of the fire suppression system.
If fire is detected, the control panel receives a signal, automatically entering FIRE mode.
Once activated, the control panel sounds an audible alarm, initiates the shutdown sequence and triggers the cylinder valve to discharge the foam to the fire.
Fire mode can also be activated by using the remote actuator.
Loss of Pressure (LOP) Detection
If fire is detected the pressurised sensor tube will rupture, releasing inert gas.
The release of gas triggers the cylinder valve to discharge foam to the fire.
The cylinder valve can also be manually triggered with the remote actuator.

Muster 360 Cloud Based Portal
Muster 360 is a dedicated cloud-based portal for use exclusively with Muster systems. It provides a framework for conducting a fire risk assessment, specifying system requirements.
Three CAT 345 GC mining excavators bound for a mining site had Muster foam-based systems installed and commissioned before being moved to the Brisbane port.
Why Fluorine-Free Foam (F3) is the Responsible Choice for Your Site
Legacy AFFF contains PFAS — chemicals that persist in soil and groundwater and are subject to increasing regulatory restriction across Australia. MusterFire uses fluorine-free foam (F3) as its standard suppression agent, eliminating PFAS risk entirely.
What is F3 Foam?
F3 foam forms a film to provide the same blanketing and vapour-sealing performance as AFFF without any fluorinated compounds. It is biodegradable and PFAS-free, meeting Australian environmental protection regulations.
Environmental Compliance
F3 foam is safe for deployment on agricultural land, in water catchment zones, and near ecologically sensitive areas. It complies with Australian environmental protection policies.
Equivalent Performance
F3 foam creates the same fuel surface blanket as AFFF, suppressing Class B liquid hydrocarbon fires. Performance is certified under AS 5062:2022.
Future-Proofing Your Fleet
As PFAS regulations tighten across Australia, specifying fluorine-free systems now protects your operation from future compliance liability. All new Muster foam systems ship with F3 foam as standard.

Foam-Based Systems Across Industries
Mining
Excavators, dozers, haul trucks, and underground loaders. The foam system is the primary suppression solution for liquid hydrocarbon fuel fires on mining mobile plant, certified to AS 5062:2022.
Agriculture
Combine harvesters and tractors during harvest season. Foam suppression with re-ignition prevention is critical where dry crop debris accumulates around hot engine components.
Construction & Tunnelling
Excavators and mobile plant in confined tunnelling environments with limited egress. Automatic foam discharge requires no operator presence in the risk zone.
Waste Management
Compactors and shredders handling combustible waste. A Queensland waste facility fitted a Muster foam system on their compactor, providing extra discharge time and full AS 5062 compliance.
Foam System as Part of a Dual Agent Installation
For machines with multiple distinct fire risk zones, the Muster foam system can be configured alongside Solid Aerosol (SAG) or Impulse Powder (IPS) modules as part of a dual or triple agent installation. Muster control panels manage detection and activation across all zones simultaneously, with the correct agent delivered to each risk area automatically.
This configuration is standard practice on large mining excavators where the engine bay and fuel area use a foam system, and enclosed electrical and alternator bays use SAG units. Your authorised Muster distributor will design the correct combination using Muster360 during the initial fire risk assessment.

Muster foam systems are primarily designed for Class B fires involving liquid hydrocarbons such as diesel fuel, hydraulic oil, and lubricants. The foam blanket prevents vapour release and re-ignition. F3 foam can also assist with Class A solid material fire scenarios.
Is fluorine-free foam (F3) as effective as AFFF?
Yes. F3 foam has been independently tested and certified under AS 5062:2022 to match AFFF performance in suppressing Class B fires. It creates the same vapour-sealing film on the fuel surface and provides equivalent cooling and re-ignition prevention without any PFAS compounds.
What cylinder sizes are available for the Muster foam system?
Muster foam cylinders are available from 15L to 110L capacity. The correct size is determined during system design using the Muster360 risk assessment design table.
What temperature range does the foam system operate in?
The Muster foam-based system operates from -40°C to +60°C, making it suitable for underground mining, alpine agriculture, and high-temperature tropical and desert industrial environments.
What is the difference between LHD and LOP detection?
LHD is an electrically controlled system where a heat-sensitive cable triggers an alarm at the panel. LOP uses pressurised tubing that physically ruptures at the point of flame contact, triggering discharge mechanically without any electrical power.
Is the Muster foam system certified to AS 5062?
Yes. The Muster foam-based fire suppression system is certified to AS 5062:2022. Commissioning documentation confirming compliance is generated through Muster360 for each installation.
Can the foam system be installed on autonomous vehicles?
Yes. All Muster systems are designed for both manned and autonomous vehicle applications. The Remote Activation Device allows fire suppression to be triggered from a safe distance without an operator on the machine.
What happens after the foam system discharges?
After discharge, an authorised Muster distributor must inspect the machine before it returns to service. The cylinder is recharged or replaced, the detection system is inspected, and the event is logged in Muster360 for compliance records.
Can the foam system be combined with SAG or IPS?
Yes. Muster foam systems can be combined with SAG or IPS modules in a dual-agent configuration controlled by a single alarm panel.
Is PFAS-free foam safe on agricultural land?
Yes. Muster's fluorine-free foam (F3) is biodegradable and PFAS-free, making it safe for discharge on agricultural land, near waterways, and in environmentally sensitive zones.
