Which of the following is considered the most false regarding fireproofing materials in high-rise construction?

The statement that is considered the most false regarding fireproofing materials in high-rise construction is that any coating to fireproof steel beams that will be covered with a finished wall is acceptable. In high-rise construction, fireproofing is critical for ensuring that structural elements such as steel beams can withstand high temperatures and maintain their integrity during a fire.

However, if these coated beams are going to be concealed behind finished walls, it raises concerns about compliance with fire safety codes and regulations, as the fireproofing would not be visible or verifiable during inspections. Properly fireproofed steel must remain accessible for inspection to ensure safety standards are met, making this statement misleading.

In contrast, coatings should definitely be used in high-rise applications to ensure safety, contrary to any implication that they should not. Fireproofing materials are indeed required for steel structures in high-rises to protect against the risk of collapse in the event of a fire. Moreover, while steel beams do have specific requirements for fire resistive treatments, they do not always require special certifications as long as the materials and methods comply with applicable building codes. Thus, the importance of visible and accessible fireproofing in high-rise applications renders the first statement the most false among the given options.
