According to OSHA safety standards, masonry walls exceeding which height must be braced?

Masonry walls must be adequately braced to ensure safety during construction, particularly when they exceed a significant height. According to OSHA standards, there are specific guidelines established for ensuring that these structures do not pose a danger to workers.

The correct answer indicates that masonry walls exceeding a certain height must always be braced. This requirement is vital because unbraced walls can be unstable and pose serious risks of collapse, particularly in adverse weather conditions or if disturbed by construction activities. Therefore, it's essential for contractors and builders to be aware of these regulations to ensure not only compliance but, more importantly, the safety of workers on the job site.

Furthermore, bracing provides support to the structure during the construction phase, ensuring that the masonry remains intact until it is fully cured and can support itself. By understanding these safety standards, construction teams can prevent accidents and injuries related to failing structures.
