AVD Lithium-ion Battery Fire Extinguishers

Lithium-ion batteries are found in a growing range of equipment used, charged and stored onboard vessels. The Aqueous Vermiculite Dispersion (AVD) fire extinguisher provides first-response, early intervention for identified local and distributed battery risks, complementing the vessel's wider fire safety and emergency response procedures. The AVD agent is discharged as a fine mist that helps cool the affected battery while creating a protective barrier over the burning material. This combined action helps control the fire and reduce heat transfer to surrounding cells.

The product range includes a 9 l portable stored-pressure extinguisher and a 50 l cartridge-operated mobile unit for applications requiring greater extinguishing-agent capacity. Potential applications include battery charging and storage areas, areas containing portable or battery-powered equipment, workshops and equipment stores aboard passenger vessels, RORO/ROPAX vessels, yachts, offshore and specialist vessels. Product selection and positioning should reflect the specific battery hazard, location, vessel emergency procedures and risk assessment.

Regular inspection and maintenance should be carried out in accordance with the manufacturer's instructions, applicable regulations and vessel maintenance schedules to ensure optimal performance and regulatory compliance. Following discharge, the extinguisher must be removed from service and inspected and recharged by trained service personnel using the manufacturer’s specified procedures, extinguishing agent and components.
