Self-supporting fire walls are most commonly found in which type of facilities?

Self-supporting firewalls are primarily designed to act as barriers that are capable of standing independently without support from the building structure. They are most commonly found in large open industrial facilities due to their need to compartmentalize sections for safety and fire control purposes. These facilities often contain significant amounts of flammable materials and larger spaces that require effective fire protection strategies.

The use of self-supporting firewalls allows for greater flexibility in the layout and design of the facility while still adhering to fire safety codes. They can effectively divide large areas into smaller, more manageable sections, which helps in containing fire incidents and preventing the spread of smoke and flames.

In contrast, while commercial retail stores, high-rise residential buildings, and office complexes also have fire safety measures in place, they typically utilize different types of walls and barriers that are integrated into the overall structure, rather than employing standalone firewalls as seen in industrial settings. The nature of operations and materials present in large industrial facilities necessitates the use of self-supporting firewalls to meet stringent safety regulations and enhance overall fire safety.
