Ministerial Order no. 2023-416 of 11 July 2023 amending Ministerial Order no. 2018 1079 of 21 November 2018 regulating the general principles of safety against the risks of fire and panic in buildings.

This order makes it compulsory to install a carbon monoxide detector in existing and future installations in two cases:

– in the presence of instantaneous water heaters fuelled by gas or liquefied hydrocarbons ;

– in homes connected to the fuel gas distribution network.

The detector must be capable of emitting a local audible alarm to warn the occupant of an abnormal rise in carbon monoxide levels.

This local alarm may be supplemented by the simultaneous broadcast of information on one or more connected devices (smartphone, tablet, etc.).
