A safety system for for example a band saw (2, 3, 4) driven by a motor (5) and having a working plane (1) is lighted with UV light by a lighting means (6, 7) with modulated light. When a glove (15) with fluorescent material enters the supervised area (13, 14) an optical system (8) detects the fluorescent light excited from the glove and activates a signal means (17) and one or more blocking or cutting means (16). |
