Fire protection methods can be categorized into which two types?

Fire protection methods are primarily categorized into two types: active and passive protection. Active protection refers to systems that require action or intervention to work, such as fire alarms, sprinkler systems, and fire extinguishers. These systems react when fire is detected and actively work to suppress or control the fire, providing immediate safety measures.

On the other hand, passive protection involves built-in features of a building that help prevent the spread of fire and smoke. This includes fire-resistant walls, floors, and doors, as well as the strategic design of the building to compartmentalize and limit fire spread. These measures do not require any action to be effective and are essential for a building's overall fire safety strategy.

The other options explore different concepts that do not align with the standard categorization of fire protection methods. For example, preventive and reactive protection describe approaches to managing risks but do not specifically address how fires are controlled or contained. Insured and uninsured protection pertains to financial aspects of property coverage rather than physical fire safeguarding measures. Internal and external protection could suggest methods based on the location of fire protection measures, but it does not capture the comprehensive strategies of active and passive protection.
