Scaffolding

A scaffold is a temporary elevated work platform used to support workers and materials. They allow safe access to elevated work areas when used properly.

• Work cannot be safely performed from the ground, a ladder, or other means.
• Tasks require stability, mobility, and adequate workspace (e.g., masonry, painting, mechanical installations).

• Competent Person: Required by OSHA to supervise erection, dismantling, and modification. Must identify hazards and ensure safe use.
• Qualified Person: Designs scaffold systems and determines load capacities.
• Authorized Users (Workers): May only use scaffolds after completing required safety training.

• Supported Scaffolds: Platforms supported by poles, legs, frames, or outriggers.
• Suspended Scaffolds: Platforms suspended by ropes or other non-rigid means (e.g., window washing rigs).
• Mobile Scaffolds: Portable, caster-supported platforms that can be moved.

• Falls: Falls from elevation are the leading cause of injuries and fatalities.
• Scaffold Collapse: Caused by overloading or improper assembly.
• Falling Objects: Loose materials or tools striking workers below.
• Electrocution: Contact with overhead power lines.

• Install guardrails, midrails, and toeboards when working 10 feet or higher.
• Use personal fall protection harnesses when required.
• Ensure scaffolds are inspected daily by a competent person before each shift.
• Verify platforms are fully planked with no gaps.
• Maintain a minimum safe distance of 10 feet from overhead power lines.
• Never exceed the manufacturer’s load ratings.
