UV-C light is increasingly used for healthcare disinfection, but misconceptions and myths can hinder its adoption. Proper usage and safety protocols eliminate harm to patients and staff, but it's not a replacement for standard cleaning practices. Effectiveness depends on device selection and proper implementation, and some UV-C devices produce harmful ozone. While UV-C light cannot penetrate solid materials, it's highly effective on exposed surfaces when positioned correctly. Understanding the facts about UV-C light for healthcare is essential to ensure its safe and effective use.
