Where are containers not allowed to be stored?

The storage of containers, particularly those holding flammable gases like LPG or CNG, on roofs of buildings is prohibited due to several factors related to safety and accessibility. Roofs generally have limited access, which can make emergency responses difficult in case of leaks or explosions. Additionally, the heat generated by the sun can increase the pressure within the containers, posing a greater risk of rupture or explosion. The elevation also exposes the containers to possible impact from falling debris or equipment, further increasing the risk. Thus, this choice emphasizes the importance of maintaining a safe environment in all areas where such containers are utilized or stored.
