Ceiling fans are high-speed devices.<\/h4>\n

<\/p>\n

Let’s take the case of a common blade fan[1]<\/a>. Its rotation speed often exceeds 200 rpm. That’s 50 km\/h at the tip of the blades!<\/h4>\n

<\/p>\n

A head-on collision with a spinning blade at 50 km\/h can be a nasty experience, particularly if you are hit on the hand or head.<\/h4>\n

<\/p>\n

To take this into account, let’s look at the safety rules that have been laid down to limit the risk of injury.<\/h4>\n

Overseas, regulations ahead of the game?<\/h3>\n

<\/p>\n

Ceiling fans have been around for a long time in these regions.<\/p>\n

<\/p>\n

The first regulations in the French overseas departments and territories to describe safety height rules for air blowers is the RTAA DOM.[i]<\/a>. The current application sheet<\/a>, contains the following recommendation [ii]<\/a>:<\/a><\/p>\n

Minimum height under blades<\/h4>\n

<\/p>\n

If fans are installed under the ceiling, a minimum height under the blades must be defined for safety reasons.<\/p>\n

<\/p>\n

The minimum height between the finished floor and the fan blades is generally one of the recommendations provided by the industry. This is usually set at 2.30 m if there is no protective device.<\/p>\n

More recently, the thermal regulations for Guadeloupe<\/a>, drawn up with the active participation of the CSTB [iii]<\/a>and published at the end of 2019, are even more precise:[iv]<\/a><\/a><\/p>\n
