According to Decree no. 2010-750 of July 2, 2010 on the protection of workers against the risks arising from artificial optical radiation, access to an operating room containing laser-emitting equipment must be signposted appropriately for the risk, and access must be restricted.

DosAlert Laser is a device for signalling areas at risk of exposure to artificial optical radiation. Thanks to this signage, staff outside the room can see whether the surgical laser in the room is operating.
