Masonry construction, construction safety: Manufactured tubular scaffold posts supported at base by unstable brick cribbing. Preferred methods would include screw-jacks at scaffold bases extended to stable mud sill or other stable footing. 2" x 10" wood planks form working platform for masons to stand on and a higher material platform on which masonry units (brick here) and mortar are placed. The outside of the material level should have guardrails to protect laborers placing and stacking brick and working with mortar. The ramp between the side and front sections of scaffold should also have guardrails and also cleats for good footing, especially in the wet weather in which masons are working. Ann Arbor, Michigan, 2004
OSHA 1926-L requires: Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills or other adequate firm foundation. Footings shall be level, sound, rigid, and capable of supporting the loaded scaffold without settling or displacement. Unstable objects shall not be used to support scaffolds or platform units.
