Which material typically does NOT serve as passive fire protection?

Passive fire protection is designed to contain fires or slow their spread without active interventions, relying instead on the building's structure and design. Fire escape ladders are considered active fire protection elements because they provide a means of escape in the event of a fire, rather than preventing or controlling the fire itself. They are intended to assist occupants in evacuating safely and do not contribute to fire resistance or containment measures within the building.

In contrast, spray-applied cementitious materials, fire doors, and fire-resistant glass play critical roles in passive fire protection systems. Spray-applied cementitious materials are used to coat structural elements, enhancing their fire resistance. Fire doors are designed to close off spaces and prevent the spread of flames and smoke, maintaining compartmentalization. Fire-resistant glass is used in openings to maintain the integrity and protection of fire-rated walls, allowing visibility while still inhibiting the passage of heat and flames.

Understanding the distinction between active and passive fire protection systems helps clarify the roles of these materials and devices in fire safety strategies.
