Scaffolding
This document goes over scaffolding safety and includes the link to enroll in the Scaffolding Safety Canvas course, which qualified employees as competent persons.
General Overview & Roles
What is a scaffold and when is it used?
A scaffold is a temporary elevated work platform used to support workers and materials. Scaffolds allow safe access to elevated work areas when used properly.
Scaffolds are typically used in the following situations:
- Work cannot be safely performed from the ground, a ladder, or another means.
- Tasks require stability, mobility, and adequate workspace, such as masonry, painting, or mechanical installations.
Who is authorized to work on or around scaffolds?
- 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.
Important: Scaffold responsibilities vary by role. Make sure the person performing or supervising the work has the appropriate training and authorization.
Types & Common Hazards
What are the primary types of scaffolds?
- Supported Scaffolds: Platforms supported by poles, legs, frames, or outriggers.
- Suspended Scaffolds: Platforms suspended by ropes or other non-rigid means, such as window washing rigs.
- Mobile Scaffolds: Portable, caster-supported platforms that can be moved.
What are the main scaffolding hazards?
- Falls: Falls from elevation are a major scaffold hazard.
- Scaffold Collapse: May result from overloading or improper assembly.
- Falling Objects: Loose materials or tools may strike workers below.
- Electrocution: Contact with overhead power lines can create serious electrical hazards.
Hazard Awareness: Falls, collapse, falling objects, and electrical contact should be evaluated before scaffold work begins.
Safety Controls & Training
What required controls must be in place?
- 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.
Critical: Never use a scaffold that has not been properly inspected, is overloaded, or lacks required fall-protection measures.
How do I complete Scaffolding Safety Training?
Scaffolding Safety training is available on Canvas. Completion of the course and achieving an 80% score on the quiz will certify an employee as a competent person.
