OSHA Scaffolding Standards: Essential Fall Protection Resources

• OSHA scaffolding requirements under 29 CFR 1926 Subpart L
• When fall protection is required on scaffolds
• Guardrail system requirements and specifications
• Personal fall arrest system guidelines
• Training requirements for scaffold safety
• Common scaffolding violations and OSHA citations
• Employer responsibilities for inspection and compliance
• Resources that support fall protection programs

Falls from scaffolding remain one of the leading causes of construction fatalities. Understanding OSHA standards for scaffolding safety standards is the first step toward preventing injuries and maintaining a compliant job site.

Personal Fall Arrest Safety

Personal fall arrest systems are one of two types of fall protection typically required on scaffolds. These generally include some combination of a harness, D-rings, snap hooks, lifelines, and an anchorage point. Here's a quick breakdown of general requirements for personal fall arrest systems:

• Personal fall arrest systems must attach to a vertical lifeline, horizontal lifeline, or scaffold structural member via a lanyard.
• Vertical lifelines must fasten to a fixed anchorage point, independent of the scaffold, and must be protected from sharp edges and abrasion.
• Safe anchorage points include structural members of buildings. Standpipes, drain pipes, vents, electrical conduits, and similar objects are not structural parts of the building and, as a result, are never safe anchorage points.
• Two or more vertical lifelines may not attach to each other, nor to the same point of anchorage.

Guardrail Safety

Guardrails are another form of fall protection. Here's a brief look at general requirements for guardrails:

• Guardrails must cover all open sides and the ends of the platform. Top rails, midrails, screens, mesh, intermediate vertical members, and solid panels must withstand a force of at least 150 pounds applied in any downward or horizontal direction.
• Toprails on scaffolds created and used after January 1, 2000, must be between 38 and 45 inches tall. Toprails for scaffolds created and used before that date may be between 36 and 45 inches tall.

Fall Protection on Suspended Scaffolds

Suspended scaffolds are platforms suspended by cables, ropes, or other non-rigid methods from an overhead structure. Window washers on skyscrapers usually work from suspended scaffolds, but construction workers also use them on extremely tall structures.

OSHA generally requires a personal fall arrest system or guardrail system for workers on suspended scaffolds 10 feet or higher above a lower level. However, employees on single-point and two-point adjustable suspended scaffolds must use both a personal fall arrest system and a guardrail.

Fall Protection on Supported Scaffolds

Supported scaffolds include one or more platforms supported by poles, legs, uprights, outrigger beams, posts, frames, or other types of rigid supports.

Employees must use a personal fall arrest system or a guardrail system on supported scaffolds 10 feet or higher above a lower level.

Horizontal lifelines must be anchored to two or more structural members of the scaffold.

Guardrail systems must be installed along all open sides and ends of platforms. Midrails and toe boards are also required, unless workers always use a personal fall protection system.

Other Types of Scaffolds

Supported and suspending scaffolds are just two of the many forms of scaffolding. Here's a quick breakdown of OSHA fall protection requirements for other types of scaffolding.

• Aerial lifts, boatswains' chair, catenary scaffold, float scaffold, ladder jack scaffold, and needle beam scaffold: Employees must use a personal fall arrest system.
• Crawling board: Employees must use a personal fall arrest system, guardrail system, grabline (with a 3/4-inch diameter), or equivalent handhold fastened beside each crawling board.
• Self-contained scaffold: Workers must use both a personal adjustable scaffold arrest system and a guard rail system.
• Other forms of scaffolding: Employees must use a personal fall arrest system or a guardrail system.

Safe Scaffolding Resources and Solutions

OSHA estimates that protecting workers from scaffold-related accidents could prevent up to 50 deaths every year.
