Flagpole safety in the United States: wind, power lines and work at height

A flagpole is a tall structure that carries a large surface in the wind, often close to houses, sidewalks and power lines. The risks are greatest when a pole is installed, raised or taken down, or when it carries more flag than it was designed for. This guide describes the main risks and the rules that apply to them in the United States.

Wind and flag size

A flagpole is designed for a maximum wind speed with a flag of a given size. According to Concord American Flagpole, commercial flagpoles are designed to the ANSI/NAAMM FP 1001-07 guide specification of the National Association of Architectural Metal Manufacturers, which publishes a map from ASCE 7 of nominal 3-second gust wind speeds at 33 ft above ground. Concord’s wind ratings assume a ground-set pole flying a nylon flag of the recommended size; polyester flags, double flags and larger flags change the load. Concord warns that a pole whose rating does not meet the maximum wind speed for the site, or that flies flags larger than the recommended size, can result in personal injury and property damage, and notes that special wind zone areas need attention of their own.

Public projects set the design wind speed by location: the New York State Department of Transportation designs its aluminum flagpoles for 80 mph in New York City, Long Island and several other counties and 70 mph elsewhere in the state.

Storms

Concord American Flagpole states that flags should always be removed from the flagpole during severe weather events. The Flag Code describes not displaying the flag on days when the weather is inclement, except when an all-weather flag is displayed (4 U.S.C. § 6(c)); as a guide for civilians it has no penalties, but the wind load is the same whatever the rules.

Overhead power lines

Raising a flagpole near a power line is one of the most dangerous moments. Concord urges extreme care when flagpoles are installed near overhead power lines. For workers, OSHA sets minimum distances in 29 C.F.R. § 1910.333(c)(3): an unqualified person working near overhead lines, and the longest conductive object the person may contact, stays at least

Under the same rule, objects without an insulating rating for the voltage are treated as conductive. An aluminum flagpole is conductive, so the distance applies to the whole length of the pole while it is lifted into place.

Buried utilities

Digging a foundation can hit gas, electric, water and communication lines. According to the Common Ground Alliance, every digging project requires contacting 811 a few days in advance, some utilities are buried just inches below the surface, and shovels are the second most common tool involved when buried utilities are damaged. More in the guide to installing a flagpole.

Work at height

Replacing a halyard or a truck on a tall pole means working at height. For employers in construction, OSHA requires fall protection for employees on a walking or working surface with an unprotected side or edge 6 ft or more above a lower level, by guardrails, safety nets or personal fall arrest systems (29 C.F.R. § 1926.501). Faults that call for work at the top are covered in the guide to flagpole repair.

The pole and the public

A flagpole also affects people passing by. Florida’s HOA law, for example, protects a flagpole only as long as it does not obstruct sightlines at intersections and is not in an easement, and local codes often require setbacks from property lines. A pole in poor condition, with a corroded base or loose parts, can fall; checks are described in the guide to flagpole maintenance, and the halyard and truck in the guide to how a flagpole works.
