Hazards are everywhere at medical facilities and are often invisible to patients. Indoor "in use" signs alert patients and medical staff of areas where there are x-rays in use. Illuminated x-ray in use signs bring attention to the message to let everyone know that the room is in use and that x-rays are in use. An illuminated in use light can prompt staff to use extra caution or wear additional PPE when entering a room. Our indoor in use signs come in 2 voltage ranges, 120-277VAC and 12-24VDC. Need something other than x-ray in use? We can customize your "in use" light message.
