Which of the following is a common cause of fire?

Improperly stored flammable materials is indeed a common cause of fire. Materials such as chemicals, solvents, and other flammable substances can ignite easily if they are not stored correctly. This might include keeping them too close to a heat source, not using appropriate containers, or failing to label them properly. When these materials are stored in a way that doesn’t follow safety regulations, they can become a significant fire hazard, potentially leading to severe consequences including property damage, injuries, or even loss of life.

Addressing proper storage practices is essential in workplaces and other environments to prevent ignitions. Awareness and training about the correct handling and storage of flammable materials are key components of effective fire safety management.
