Flagpole safety in France: wind, work at height, networks

A flagpole is tall and slender, exposed to the wind, and often installed near walkways, car parks or power lines. The risks come mainly from wind, from work at height during installation and maintenance, and from overhead and buried networks. This guide presents these risks and the related rules and recommendations in France.

Wind

A flag catches a lot of wind. The larger it is and the taller the pole, the greater the forces on the pole, the fixing and the foundation. The national annex to Eurocode 1 (NF EN 1991-1-4) divides metropolitan France into four wind regions, and makers state a maximum flag size or wind speed for their poles.

According to the flag maker Doublet, its flag size guide values apply to winds up to force 8; above that, the maker recommends taking the flag down to avoid damaging the pole. When Météo-France forecasts storms, many owners take their flag in. A torn flag or one wrapped around the pole also increases the loads.

Signs of wear that can point to a problem are a crack at the foot of the pole, corrosion on the base plate or anchor rods, a pole that leans or moves in its sleeve, and unusual noise in strong wind. More on this is in the guide to flagpole maintenance.

Work at height

Installing a pole and working at the top (pulley, halyard, revolving truck, lighting) often involve working at height. For workers, the Labour Code governs this work: under article R. 4323-58, temporary work at height is carried out from a work surface designed, installed or equipped to protect the workers’ health and safety. According to the INRS, falls from height are the second cause of fatal work accidents, after road risk, and many accidents are caused by falls from ladders and stepladders.

A pole with a tilting base plate or a halyard operated from the ground reduces the need to climb. For large poles, specialist firms work from an aerial platform.

Power lines and networks

A pole that touches an overhead power line, during installation or when it falls, carries a risk of electrocution. According to Service Public, works without building permission, with no impact on underground networks and more than 5 metres from any overhead power line (3 metres for low-voltage lines) are not subject to a DT-DICT. Closer to lines, or if the foundation affects buried networks, the declaration provides the operators’ safety recommendations. More on this is in the guide to flagpole installation.

The public and the surroundings

Around a pole in a place open to the public, such as a car park, a campsite or a school, the risks also include vehicle impacts, vandalism of the halyard and a flag or accessory falling. An anti-theft inside halyard, protection at the foot and regular checks are common measures. The guide to flagpole repair covers damage.
