MusterFire International supplied and installed a solid aerosol fire suppression system designed specifically for battery-electric buses operating within Hancock Prospecting’s Roy Hill Mine (Nullagine) and Port Hedland operations.
The system was built to meet AS5062:2022 compliance, ensuring reliable detection and protection in high-risk environments.
The challenge
Electric mine-site buses present a unique hazard due to the presence of electronic battery management equipment located at the rear of the vehicle. Electrical short circuits in these areas can rapidly escalate, potentially igniting nearby components and spreading to the main battery packs, a situation that could have catastrophic consequences for both safety and operations. The client required a compliant, low-maintenance, and effective suppression solution that would prevent such incidents and safeguard personnel and assets.
The solution
To meet these requirements, MusterFire deployed the Muster Solid Aerosol Generator (SAG) system, integrated with low-temperature linear heat detection wire for early fault identification and rapid activation. Three M2SAGL-M2 units (0.2 kg each) were strategically installed within the hazard zone to ensure optimal coverage while minimising impact on sensitive electrical components. This configuration provided an efficient and lightweight solution ideal for EV applications and ensured compliance with site safety standards. The installation was completed smoothly on-site within tight operational timeframes.
The outcome
The SAG system successfully met the client’s performance and compliance requirements, offering early fire detection, minimal service costs, and an impressive 10-year shelf life. The client benefited from reduced maintenance demands and increased confidence in their EV fleet’s fire safety. This project demonstrates MusterFire’s capability to deliver custom, compliant fire protection systems tailored to the evolving needs of electric and hybrid mining equipment.
