Abstract

L'invention concerne un procédé et un système avec lesquels la sécurité est accrue durablement lors de l'utilisation de lunettes de protection laser. Le procédé comprend les étapes suivantes consistant : - à surveiller quelles paires de lunettes de protection laser (2.1.1, 2.2.2, 2.3.2, 2.4.1) sont en cours d'utilisation; - à contrôler pour chaque paire de lunettes de protection laser utilisée (2.1.1, 2.2.2, 2.3.2, 2.4.1) si elle est placée correctement devant les yeux de l'utilisateur et/ou si la paire de lunettes de protection laser (2.1.1, 2.2.2, 2.3.2, 2.4.1) est appropriée pour les longueurs d'onde de la lumière émise par les lasers (3.1, 3.2) et/ou si la paire de lunettes de protection laser (2.1.1, 2.2.2, 2.3.2, 2.4.1) remplit encore ses spécifications optiques; - à éteindre ou à bloquer tous les lasers (3.1, 3.2) si au moins l'une des paires de lunettes de protection laser utilisées (2.1.1, 2.2.2, 2.3.2, 2.4.1) n'est pas correctement placée devant les yeux de l'utilisateur et/ou leurs spécifications optiques ne sont plus remplies; - si au moins une paire de lunettes de protection laser (2.1.1, 2.2.2, 2.3.2, 2.4.1) est inappropriée pour les longueurs d'onde d'au moins l'un des lasers (3.1, 3.2), à éteindre ou à bloquer le ou lesdits lasers (3.1, 3.2).
