Published by SALUS

Guardrail systems are required in various construction scenarios in Virginia to protect employees from falls. Here's when they are typically needed:

  • General Fall Protection: On walking/working surfaces with unprotected sides or edges that are 6 feet (1.8 m) or more above a lower level [1].
  • Leading Edges: When constructing a leading edge 6 feet (1.8 m) or more above lower levels [1].
  • Hoist Areas: In hoist areas where employees could fall 6 feet (1.8 m) or more to lower levels [2].
  • Holes: Around holes (including skylights) that are more than 6 feet (1.8 m) above lower levels [2].
  • Formwork and Reinforcing Steel: On the face of formwork or reinforcing steel when employees could fall 6 feet (1.8 m) or more to lower levels [2].
  • Ramps, Runways, and Walkways: On ramps, runways, and other walkways where employees could fall 6 feet (1.8 m) or more to lower levels [2].
  • Excavations: At the edge of excavations 6 feet (1.8 m) or more in depth, especially when the excavation isn't easily visible [2].
  • Dangerous Equipment: Around dangerous equipment where employees could fall into or onto the equipment; this applies to situations less than 6 feet (1.8 m) and 6 feet (1.8 m) or more above the equipment [2].
  • Overhand Bricklaying: When performing overhand bricklaying and related work 6 feet (1.8 m) or more above lower levels [2].
  • Employees reaching below: When an employee is reaching more than 10 inches (25 cm) below the walking/working surface [3].
  • Low-slope roofs: When employees are engaged in roofing activities on low-slope roofs with unprotected sides and edges 6 feet (1.8 m) or more above lower levels [3].
  • Steep roofs: When employees are working on a steep roof with unprotected sides and edges 6 feet (1.8 m) or more above lower levels [3].
  • Precast concrete erection: When employees are engaged in the erection of precast concrete members 6 feet (1.8 m) or more above lower levels [3].
  • Residential construction: When employees are engaged in residential construction activities 6 feet (1.8 m) or more above lower levels [3].
  • Wall openings: When employees are working on, at, above, or near wall openings where the outside bottom edge of the wall opening is 6 feet (1.8 m) or more above lower levels and the inside bottom edge of the wall opening is less than 39 inches (1.0 m) above the walking/working surface [3].
  • Scaffolds: On scaffolds more than 10 feet (3.1 m) above a lower level [4].

In many of these situations, alternatives to guardrail systems, such as safety net systems or personal fall arrest systems, may be acceptable 1, 2, 7. Employers in Virginia must comply with OSHA regulations, ensuring fall protection is provided where required 3, 9.

## 29 CFR 1926 (OSHA) Toeboard means a low protective barrier that will prevent the fall of materials and equipment to lower levels and provide protection from falls for personnel. Unprotected sides and edges means any side or edge (except at entrances to points of access) of a walking/working surface, e.g., floor, roof, ramp, or runway where there is no wall or guardrail system at least 39 inches (1.0 m) high. Walking/working surface means any surface, whether horizontal or vertical on which an employee walks or works, including, but not limited to, floors, roofs, ramps, bridges, runways, formwork and concrete reinforcing steel but not including ladders, vehicles, or trailers, on which employees must be located in order to perform their job duties. Warning line system means a barrier erected on a roof to warn employees that they are approaching an unprotected roof side or edge, and which designates an area in which roofing work may take place without the use of guardrail, body belt, or safety net systems to protect employees in the area. Work area means that portion of a walking/working surface where job duties are being performed.

## 29 CFR 1926 (OSHA) - (ii) Each employee reaching more than 10 inches (25 cm) below the level of the walking/working surface on which they are working, shall be protected from falling by a guardrail system, safety net system, or personal fall arrest system. NOTE: Bricklaying operations performed on scaffolds are regulated by subpart L-Scaffolds of this part. - (10) Roofing work on Low-slope roofs. Except as otherwise provided in paragraph (b) of this section, each employee engaged in roofing activities on low-slope roofs, with unprotected sides and edges 6 feet (1.8 m) or more above lower levels shall be protected from falling by guardrail systems, safety net systems, personal fall arrest systems, or a combination of warning line system and guardrail system, warning line system and safety net system, or warning line system and personal fall arrest system, or warning line system and safety monitoring system. Or, on roofs 50-feet (15.25 m) or less in width (see appendix A to subpart M of this part), the use of a safety monitoring system alone [i.e. without the warning line system] is permitted. - (11) Steep roofs. Each employee on a steep roof with unprotected sides and edges 6 feet (1.8 m) or more above lower levels shall be protected from falling by guardrail systems with toeboards, safety net systems, or personal fall arrest systems. - (12) Precast concrete erection. Each employee engaged in the erection of precast concrete members (including, but not limited to the erection of wall panels, columns, beams, and floor and roof 'tees') and related operations such as grouting of precast concrete members, who is 6 feet (1.8 m) or more above lower levels shall be protected from falling by guardrail systems, safety net systems, or personal fall arrest systems, unless another provision in paragraph (b) of this section provides for an alternative fall protection measure.
