What does a "fire wall" symbol indicate in building blueprints?

The "fire wall" symbol in building blueprints is specifically used to indicate a wall that is engineered to prevent the spread of fire between different structures or sections of a building. This type of wall is constructed with materials that have a high fire-resistance rating, often using concrete, brick, or other non-combustible materials, and it is designed to withstand fire for a specified duration.

The presence of fire walls is crucial in architectural design as they help to contain a fire should one occur, thus protecting occupants and limiting property damage. This function is a key aspect of building safety codes, which require fire walls in certain scenarios to compartmentalize spaces and reduce the risk of fire spreading uncontrollably.

In contrast, options that refer to aesthetic purposes, decorative features, or general room separation do not accurately capture the critical safety role that a fire wall plays in construction and fire prevention strategies.
