Suspended ceilings offer a modern appearance and allow the concealment of cables, pipes, and technical installations, but they can become a hidden source of risk if fire safety requirements are not followed. Behind the sleek panels may lie vulnerabilities that, in the event of a fire, can significantly worsen the situation. This is why careful inspection of these areas is essential for the protection of the building and its occupants.
A first important aspect concerns fire dampers and smoke dampers. These must be correctly installed on ventilation routes and remain accessible for periodic inspections. Their role is essential: fire dampers ensure fire compartmentation, limiting the spread of flames between rooms, while smoke dampers allow the controlled evacuation of smoke and hot gases, facilitating the intervention of emergency teams.
Equally important are smoke detectors. Standard P118/3-2015 requires that they be installed not only below the suspended ceiling but also above it, when the concealed space exceeds 800 mm or contains cables and combustible materials. To function effectively, detectors must be cleaned and tested periodically in accordance with the maintenance plan.
Another critical element is the materials used in the structure of the suspended ceiling. According to P118/1-2025, Article 2.3.6, only non-combustible materials or materials with fire reaction class A1 or A2-s1,d0 may be used. The use of foam, films, or panels made of combustible plastics without fire protection is prohibited, as they can contribute to rapid fire development and the release of toxic smoke.
Special attention must also be given to electrical cables. Cables passing through fire compartments must be properly sealed to prevent the spread of flames and smoke from one area to another. It is recommended to use only Eca-certified or higher-class cables, CE-marked, in accordance with Regulation (EU) 305/2011 on construction products.
Complying with these requirements is not only a legal obligation but also a sign of responsibility toward the safety of employees and assets. Often, prevention is hidden just above eye level — in the suspended ceiling. Regular inspections and proper maintenance can make the difference between a controlled fire and a tragedy.
