A limited access zone for masonry construction should be established before construction begins. It must run the entire length of the wall and extend outward a distance equal to the height of the wall plus four feet. This zone should be on the side of the wall without scaffolding and limited only to employees actively engaged in the construction work. The limited access zone must remain in place until the wall is adequately supported to prevent overturning or collapse. For walls over eight feet high, additional bracing requirements apply before the zone can be removed.
Key Requirements:
- Established prior to masonry construction start.
- Length equals the entire wall length.
- Width equals wall height plus four feet.
- Located on the unscaffolded side of the wall.
- Restricted to construction workers only.
- Maintained until the wall is fully supported or braced (especially for walls over 8 feet).
These measures ensure worker safety by restricting access to potentially hazardous areas near masonry walls under construction and preventing accidents due to possible wall collapse or overturning.
