What feature should flammable/combustible storage rooms include to enhance fire safety?

A self-closing door is an important feature for flammable or combustible storage rooms as it helps to contain fires and prevent them from spreading to other areas. When a fire occurs, the heat can cause doors to warp or be forced open, allowing flames and smoke to escape. A self-closing door automatically remains closed, minimizing the airflow that can fuel a fire and confining it to the storage room for a longer period of time until emergency services arrive.

In addition to its containment function, a self-closing design can help to limit the ignition of other combustible materials stored nearby, providing critical additional time for evacuation and response. While other features such as ventilation systems and fire sprinklers also contribute to fire safety, they serve different roles—ventilation helps manage flammable vapors, and sprinklers suppress fires but may not effectively contain them. Emergency lighting is vital for safety during an evacuation but does not directly enhance fire prevention within the storage space. Thus, having a self-closing door is a crucial fire safety measure specifically tailored to the unique risks associated with storing flammable and combustible materials.
