Dangerous Goods Fire Suppression
Engineered fire protection for high-risk industrial environments
Dangerous goods and hazardous chemical facilities can contain different fuels, vapours, chemical reactivity and fire-escalation pathways. An appropriate suppression strategy must be designed around the actual substance, its storage and handling conditions and the consequences of a fire.
RML AU offers engineered EZCAFS Compressed Air Foam Systems (CAFS) for selected compatible flammable-liquid and industrial fire scenarios. Our focus is rapid fire control, appropriate surface coverage, protection of nearby assets, efficient water demand and management of potentially contaminated firewater.
Ask RML AU to assess a dangerous goods fire-protection application.
Dangerous goods fires are not all the same
A flammable-liquid pool fire, a leaking pressurised gas system, a reactive chemical spill and a combustible material warehouse fire are materially different hazards. A single foam agent or suppression system cannot be presumed appropriate for all dangerous goods classes.
Before recommending CAFS, review the product Safety Data Sheet (SDS), chemical compatibility, fire and explosion behaviour, storage quantities, segregation, bunding, application method, ventilation, ignition sources and emergency response provisions.
CAFS must not be assumed suitable for water-reactive substances, reactive metals, oxidising agents or other chemicals whose SDS or specialist guidance excludes water or foam application. Some polar solvents also need specifically compatible agents and validated performance.
How CAFS can protect suitable hazards
CAFS mechanically combines water, a selected foam concentrate and compressed air to provide an aerated suppression medium. Where compatibility and design performance are established, the technology may support:
Rapid control of suitable flammable-liquid and mixed industrial fires.
Effective surface coverage and cooling of exposed materials.
Vapour suppression where the fuel, foam agent and application configuration have demonstrated this capability.
Reduced water demand compared with an appropriate and documented baseline.
Lower potential firewater volumes and associated containment requirements.
Fixed or mobile protection configurations for defined risk zones.
Potential applications
Flammable-liquid storage and handling: Selected compatible fuel stores, transfer points, processing plant and bunded areas.
Industrial facilities: Manufacturing, workshops and process environments containing appropriate combustible and flammable materials.
Warehouses and logistics: Selected storage and loading facilities after assessment of the actual stored inventory and hazard classification.
Ports and industrial transport: Defined fuel-handling and cargo-related fire risks where a suitable suppression strategy is supported by hazard assessment.
Potential suitability is not a claim of approval for all fuels or classes.
A lower-water approach with environmental benefits
Depending on the fire scenario and successful design validation, effective CAFS application may reduce firefighting-water flow and therefore assist with management of storage, pumping, pipework, bunding, drainage and contaminated runoff. No specific water saving is guaranteed for dangerous goods facilities without comparable fuel-specific tests and engineering design.
RML AU places particular emphasis on fluorine-free foam options and environmental planning. Foam chemistry must still be assessed for suitability, environmental characteristics and applicable restrictions; fluorine-free is not synonymous with zero environmental impact.
Evidence before claims
RML AU/EZCAFS has undertaken flammable-liquid fire testing under defined conditions, including a pentane pan-fire configuration. The demonstrated results relate to the tested fuel, fire area, pre-burn, application rate and extinguishment conditions and cannot be generalised to all dangerous goods.
Project decisions must establish fuel compatibility, applicable foam performance, required application density, duration, discharge arrangement, exposure cooling, containment and operational requirements.
Australian design and regulatory considerations
Dangerous goods fire protection may involve WHS hazardous-chemical duties, dangerous goods classification for transport, fire authority requirements, relevant Australian Standards and site emergency planning. For instance, NSW WHS provisions require fire protection and firefighting equipment that is appropriate to the types and quantities of hazardous chemicals and site conditions. The applicability of AS 1940 or other material-specific standards must be considered for each facility.
Hazardous chemical classifications used for workplace placard and manifest thresholds should not be confused with the ADG transport classification system; assess both where relevant.
RML AU works with operators, fire engineers, developers and risk advisers to assess the fit of CAFS within an engineered protection strategy.

All applications require hazard-specific engineering, confirmation of agent compatibility, test relevance and compliance review. RML AU does not represent CAFS as universally suitable for all dangerous goods.
