Security and Innovations
Today, we are speaking with Thierry Étienne, Sales Director at TRIONYX, a specialist in safety solutions for lithium battery storage. Given the rapid development of these technologies, managing the risks associated with their storage has become a major challenge for businesses. Fire, thermal runaway, fire spread: how can these risks be prevented, and what solutions can be put in place to protect people, buildings and equipment?
1. Regulations and the RT362 standard: what the law says about the storage of lithium batteries
Q: Thierry Étienne, you are familiar with the legislation governing the storage of lithium batteries. What does it currently stipulate?
TE: Article R4412-18 of the Labour Code states that employers must take the necessary measures to prevent the presence in the workplace of ignition sources likely to cause fires or explosions. Lithium batteries are therefore clearly covered by this provision. To meet this requirement, the French Technical Recommendation RT362 was introduced in early 2026.
Q: What does this technical recommendation recommend?
TE: Limit the energy capacity stored in the cabinet. Fit the cabinet with various safety devices such as: a connected alarm, an open-door alert, an automatic circuit breaker, a dry contact to connect to the building’s fire alarm panel, a specialised automatic lithium fire extinguisher, a flame protection system, a ballistic protection system, and a ventilation system to limit the temperature inside the cabinet. This is to control thermal runaway, prevent risks associated with the spread of a lithium fire, and thus protect both property and people.
2. Why choose Trionyx safety cabinets compliant with RT362?
Q: Why are RT362 lithium cabinets essential for storing lithium batteries?
TE: We have all heard at least once of an incident, or even a tragedy, linked to a lithium battery fire, whether in an industrial or domestic setting. Our RT362 cabinets feature all the equipment mentioned above, and the P3500T1 versions are certified for 90 minutes in accordance with standard EN 14470-1, offering exceptional fire resistance of… 180 minutes in the event of a fire spreading from the inside out! They are designed for industrial environments, data centres, electric mobility, and many other sectors where lithium batteries pose a risk.
Q: What are the unique advantages of your cabinets?
TE: We are the only French manufacturer to offer lithium safety cabinets compliant with the RT362 technical recommendation, featuring all the equipment mentioned above: a connected alarm, an open-door alert, an automatic circuit breaker, a dry contact for connection to the building’s fire alarm panel, a specialised automatic lithium fire extinguisher, a flame protection system, a ballistic protection system, and a ventilation system to limit the temperature inside the cabinet.
