Construction Concerns: Fall Protection

By Gregory Havel

The Occupational Safety and Health Act was passed by Congress and signed into law in 1970. The first of the Occupational Safety and Health Administration (OSHA) standards and regulations were published a year later. OSHA’s regulations on fall protection were published in 1979.

Guardrail to provide fall protection

(1)

These regulations, after several revisions, require fall protection for workers in most cases six feet or more above the lower level, whether during construction or for permanent in the structure (see OSHA’s 26 CFR 1926.501(b)). Guardrails (Photo 1, above) are a common way to meet these requirements.

From OSHA’s 29 CFR 1926.502(b) Guardrail systems:

1926.502(b) Guardrail systems and their use shall comply with the following provisions:

1926.502(b)(1) Top edge height of top rails, or equivalent guardrail system members, shall be 42 inches (1.1 m) plus or minus 3 inches (8 cm) above the walking/working level. When conditions warrant, the height of the top edge may exceed the 45-inch height, provided the guardrail system meets all other criteria of this paragraph.
1926.502(b)(2) Midrails, screens, mesh, intermediate vertical members, or equivalent intermediate structural members shall be installed between the top edge of the guardrail system and the walking/working surface when there is no wall or parapet wall at least 21 inches (53 cm) high.

1926.502(b)(2)(i) Midrails, when used, shall be installed at a height midway between the top edge of the guardrail system and the walking/working level….

1926.502(b)(2)(iv) Other structural members (such as additional midrails and architectural panels) shall be installed such that there are no openings in the guardrail system that are more than 19 inches (.5 m) wide.

1926.502(b)(3) Guardrail systems shall be capable of withstanding, without failure, a force of at least 200 pounds (890 N) applied within 2 inches (5.1 cm) of the top edge, in any outward or downward direction, at any point along the top edge.

1926.502(b)(4) When the 200 pound (890 N) test load specified in paragraph (b)(3) of this section is applied in a downward direction, the top edge of the guardrail shall not deflect to a height less than 39 inches (1.0 m) above the walking/working level….

1926.502(b)(5) Midrails… shall be capable of withstanding, without failure, a force of at least 150 pounds (666 N) applied in any downward or outward direction at any point along the midrail…

1926.502(b)(6) Guardrail systems shall be so surfaced as to prevent injury to an employee from punctures or lacerations, and to prevent snagging of clothing.

1926.502(b)(7) The ends of all top rails and midrails shall not overhang the terminal posts, except where such overhang does not constitute a projection hazard.

Fall protection that does not adhere to OSHA regulation

(2)

Despite the decades that the OSHA regulations have been in place, there are still spaces in buildings with fall protection that was installed before OSHA, or in disregard of OSHA’s regulations. These spaces (Photo 2) may require access for heating, ventilating, air conditioning, electrical, or plumbing system maintenance. Access may also be required by emergency services personnel if here is a fire, or if a maintenance person develops a medical problem.

Fall protection equipment worn by construction worker

(3)

In this case, the emergency services workers may have to depend on the reach of hose streams, and forcible entry to ventilate the space. For overhaul after the fire is extinguished, or for patient removal, fall protection equipment as worn by the construction worker in Photo 3 may be required. Removal of the patient from the space may also require technical rescue techniques.

The presence of these spaces, their occupancy, and the fall protection equipment for emergency responders must be part of our preincident plans; and may require training in its use, as well as practice in technical rescue.
