Should electrical installations in hollow spaces, vertical shafts, and ventilation ducts increase the possibility of fire spreading or products combusting?

Electrical installations in hollow spaces, vertical shafts, and ventilation ducts can indeed increase the risk of fire spreading or the combustion of products. These spaces often provide pathways that can facilitate the movement of smoke, heat, and flames from one area to another, potentially allowing a small fire to become much larger and more destructive.

Furthermore, if electrical wiring is not properly installed or if it suffers damage, it can create sparks or generate heat, which could ignite surrounding materials. Therefore, when designing or inspecting electrical installations in such spaces, it is crucial to adhere to safety standards and regulations that address fire safety. These measures help mitigate the risk of fire spreading through these conduits, ensuring the safety of the structure and its occupants.

Understanding this risk reinforces the importance of using appropriate materials, barriers, and installation techniques in these critical areas to prevent a potential fire hazard.
