Guardrail System

In Plain English

A railing barrier installed along floor openings and edges to prevent workers from falling.

Definition

A guardrail system is a barrier erected along the open sides and edges of elevated work surfaces to prevent worker falls. OSHA specifies that top rails must be between 39 and 45 inches high, capable of withstanding 200 pounds of force, and that mid-rails must be installed at approximately the midpoint. Guardrails are one of the three primary fall protection methods along with safety nets and personal fall arrest systems.

Example

The GC installed double-chain guardrails around all floor openings greater than 2 inches before concrete was poured on the deck above.
