What All Do We Need to Know About Scaffolding
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other manmade structures.
Scaffolding hazards continue to rank high on the list of the most frequently cited standards in the construction industry. Some of them are:
1. Getting struck by falling tools or debris
4. Defective wood planks and inadequate planking overhang.
5. Uneven and incompact ground
6. Unsafe access to scaffold.
7. Cross bracing not adequate.
9. Bridging of scaffolds.
10. High winds and skiddy surface due to rain
11. Nature of electrical, fall, and falling object hazards
12. No guardrails on scaffolds.
OSHA's scaffolding standard has several key provisions:
1. Fall protection or fall arrest systems - Each employee more than 10 feet above a lower level shall be protected from falls by guardrails or a fall arrest system, except those on single-point and two-point adjustable suspension scaffolds. 1926.451(g)(1)
2. Guardrail height - The height of the top rail for scaffolds manufactured and placed in service after January 1, 2000 must be between 38 inches (0.9 meters) and 45 inches (1.2 meters) and before January 1, 2000 can be between 36 inches (0.9 meters) and 45 inches (1.2 meters). 1926.451(g)(4)(ii)
3. Midrails - Midrails must be installed approximately halfway between the top rail and the platform surface. 1926.451(g)(4)
4. Footings -- Support scaffold footings shall be level and capable of supporting the loaded scaffold. The legs, poles, frames, and uprights shall bear on base plates and mud sills. 1926.451(c)(2)
5. Platforms -- Supported scaffold platforms shall be fully planked or decked. 1926.451(b)
6. Capacity -- Scaffolds and scaffold components must support at least 4 times the maximum intended load. Suspension scaffold rigging must at least 6 times the intended load. 1926.451(a)(1) and (3)
7. Training -- Employers must train each employee who works on a scaffold on the hazards and the procedures to control the hazards. 1926.454
8. Inspections -- Before each work shift and after any occurrence that could affect the structural integrity, a competent person must inspect the scaffold and scaffold components for visible defects. 1926.451(f)(3)
9. Erecting and Dismantling -- When erecting and dismantling supported scaffolds, a competent person2 must determine the feasibility of providing a safe means of access and fall protection for these operations. 1926.451(e)(9) & (g)(2)
A detailed scaffolding training will explain all the regulations and provide hands-on experience on proper use of scaffolding.
