Skip to main content

Runways and Similar Walkways

The employer must ensure each employee on a runway or similar walkway is protected from falling 4 feet (1.2 m) or more to a lower level by a guardrail system. When the employer can demonstrate that it is not feasible to have guardrails on both sides of a runway used exclusively for a special purpose, the employer may omit the guardrail on one side of the runway, provided the employer ensures:

  • The runway is at least 18 inches (46 cm) wide; and
  • Each employee is provided with and uses a personal fall arrest system or travel restraint system.

Not quite 4 feet above the ground. Guard rails not required.

Openings

The employer must ensure each employee on a walking-working surface near an opening where the inside bottom edge of the opening is less than 39 inches (99 cm) above that walking-working surface and the outside bottom edge of the opening is 4 feet (1.2 m) or more above a lower level is protected from falling by the use of:

Guardrails used for wall openings.

  • guardrail systems;
  • safety net systems;
  • travel restraint systems; or,
  • personal fall arrest systems.
