📢 New fire safety requirements for batteries in telecommunications are now in force.

📃 On 5 November, the Regulation of the Minister of Digital Affairs of 21 October 2026 was announced (Journal of Laws, item 1461). It entered into force on 6 November 2026.

🔥 As a fire safety expert, I would like to draw attention to several points:

• Lithium-ion batteries with a capacity exceeding 2 kWh are subject to the requirements in Annex 3. These depend on the batteries’ capacity and location.

• For batteries located outdoors, the requirements vary according to capacity thresholds of 120, 300 and 600 kWh.

• For indoor installations, the requirements vary according to thresholds of 30, 60 and 120 kWh. Above 300 kWh indoors, fixed automatic fire-extinguishing systems are required.

• Provision is made for emergency battery disconnection and linking it to the fire safety power switch, if the building is equipped with one.

• The regulation also sets requirements for flammable gas detection and ventilation, intended to reduce the risk of explosion.

The scope of application of this legislation is strictly defined. It applies only to the telecommunications facilities and rooms specified in it.

❓ One might ask why technical conditions for buildings and their location—covering solutions similar to those set out in the regulation under discussion—have still not been issued. Surely we don’t want the growth of energy storage without any fire safety rules to increase the number of fires and their consequences in a few years’ time?!

💭 My conclusion: the selection of batteries should take the conditions for their safe use into account from the outset.

💬 I invite you to discuss fire safety in planned telecommunications installations.
