Netting - Personnel Fan / Catch Netting

What Is Personnel Fan / Catch Netting?

Definition: Personnel fan or catch netting is a safety net system that extends outward from the edge of a building, slab, or structure — usually on angled support arms — to catch and arrest a worker who falls from the work area above. Unlike debris netting, personnel catch nets are engineered, tested, and installed to meet OSHA safety net requirements for fall protection, and many systems include a fine debris liner so they also stop tools and material.

On high-rise construction, steel erection, and facade work, workers often operate near open edges where guardrails are impractical — during curtain wall installation, perimeter formwork, or steel connection work. A personnel catch fan provides passive fall protection for everyone working above it without requiring each worker to tie off. Because the net extends beyond the building line, it catches workers who fall outward from the edge, which a net directly beneath the work area cannot do.

The outward reach of the fan depends on how far above the net the work is performed — the greater the potential fall, the farther the net must extend. Nets are supported by steel outriggers, fan arms, or brackets anchored to slab edges or columns, and are typically relocated up the building as construction progresses. Through Scaffold Exchange, you can find suppliers across the U.S. that sell personnel fan and catch netting systems and compare their products and availability.

Key Components of a Personnel Catch Fan

Personnel catch fan systems vary by supplier and structure, but most include the following components.

Personnel

Personnel Safety Net

High-strength net panels with mesh sized to meet OSHA limits, designed and tested to catch and arrest a falling worker.

Structure

Fan Arms & Outriggers

Steel arms or outriggers that hold the net outward and upward from the building edge at the required horizontal extension.

Attachment

Slab & Column Brackets

Brackets, clamps, or embeds that anchor the fan arms to slab edges or columns and carry the net's impact loads into the structure.

Strength

Border & Tie Ropes

Heavy border ropes around each panel and tie ropes connecting panels to the support frame and to each other without gaps.

Debris

Debris Liner

Optional fine-mesh liner over the personnel net to catch tools, fasteners, and small debris along with the fall arrest function.

Common Applications & Job Site Uses

Personnel fan and catch netting is used on high-rise, steel, and infrastructure projects throughout the United States wherever workers are exposed to open edges.

High-rise concrete slab edges during forming

Steel erection and connector work

Curtain wall and facade panel installation

Perimeter work where guardrails are removed

Bridge and elevated structure construction

Atriums, shafts, and large floor openings

Demolition of upper floors and roofs

Projects requiring passive protection for multiple trades

How Personnel Catch Fans Compare to Other Netting Products

Personnel catch fans are one of several specialized netting products. Here is how they compare to related netting and which applications each suits best.

Netting - Debris Fan / Catch Netting

Debris catch fans

Angled fans that catch falling objects
Not rated to catch people
Protects sidewalks and adjacent property
Best for public protection from debris

Netting - Personnel Safety Nets

General personnel safety nets

Installed horizontally below the work
Catches workers falling through openings
Meets OSHA safety net requirements
Best for steel decks, bridges, and interiors

OSHA Compliance & Safety Standards

Personnel safety nets on U.S. job sites must meet OSHA standard 29 CFR 1926.502(c), which sets requirements for installation distance, outward extension, testing, mesh size, border ropes, and inspection. The required horizontal extension of the net beyond the edge increases with the vertical distance from the working level to the net. Industry guidance is provided by ANSI/ASSP A10.11, Safety Requirements for Personnel Nets.

Net installed as close as practicable below the work, never more than 30 feet below
Net extends at least 8, 10, or 13 feet outward based on vertical fall distance
Sufficient clearance under the net to prevent contact with surfaces below
Mesh openings no larger than 36 square inches or 6 inches on any side
Net drop-tested or certified as meeting OSHA's test requirements
Inspected weekly with debris removed before the next work shift

Frequently Asked Questions

Personnel fan or catch netting is a safety net system that projects outward from a building edge on angled arms to catch and arrest workers who fall from the work area above. It is engineered and tested to meet OSHA personnel safety net requirements, and often includes a debris liner to catch falling objects too.

Under OSHA, the net must extend outward at least 8 feet when the work is up to 5 feet above the net, at least 10 feet when the work is more than 5 and up to 10 feet above, and at least 13 feet when the work is more than 10 feet above. Nets may never be more than 30 feet below the working level.

Personnel catch fans are designed and tested to arrest a falling worker and must meet OSHA safety net requirements. Debris catch fans are designed only to catch falling objects and are not rated to catch people. Debris netting should never be relied on as fall protection.

Use the Scaffold Exchange vendor map to search by your location and filter by product type. You can see which local suppliers sell personnel fan and catch netting, compare their products and pricing, and contact them directly through the platform.

Personnel safety nets fall under OSHA 29 CFR 1926.502(c), which covers installation distance, outward extension, drop testing, mesh size, border rope strength, and inspection. Visit the OSHA website for full interpretations and rulings on this standard.

OSHA requires safety nets to be inspected at least once a week for wear, damage, and deterioration, and after any event that could affect the net's integrity. Materials, tools, and debris that fall into the net must be removed as soon as possible and at least before the next work shift.
