What is the trigger height for bracing masonry walls?

• A. 6 feet
• B. 8 feet
• C. 10 feet
• D. 12 feet

Answer: (B)

The correct trigger height for bracing masonry walls is 8 feet. This specific height is critical because it marks the point at which the risk of instability increases significantly during construction. When masonry walls are built higher than 8 feet without proper bracing, they become susceptible to tipping over due to their weight and the various forces acting upon them, such as wind and construction activities. The Occupational Safety and Health Administration (OSHA) has established this standard to ensure that workers are protected from potential hazards associated with unbraced masonry walls. Proper bracing not only stabilizes the structure during construction but also ensures worker safety by preventing accidents related to wall collapse. Therefore, understanding this trigger height is essential for compliance with safety regulations and for maintaining a safe working environment at construction sites.
