Standard for Safety for Ultraviolet (UV) Germicidal Equipment and Systems
Scope:
The requirements in this proposed new standard apply to ultraviolet germicidal irradiation equipment and systems emitting uncontained UV and intended for use in commercial and industrial environments and installed in accordance with the U.S. National Electrical Code (NEC), ANSI/NFPA 70 and in accordance with the Canadian Electrical Code, Part I (CEC), CSA C22.1.
Germicidal systems – intended to expose surfaces within an unoccupied area with ultraviolet (UV) energy where the exposure dose would otherwise pose a risk of personal injury to occupants. System components include UV emitters, switches, sensors and other controls acting as site or equipment safeguards. The installation and operating instructions are considered an integral system component. A system may also include devices that produce visible light.
Upper-room germicidal equipment – intended for use while a space is occupied. The UV risk is mitigated by a fixed installation at a minimum height above the floor as well as directional baffling to minimize direct emissions towards the occupied space. The effectiveness of these safeguards is confirmed by a photobiological risk assessment.
UV emitters – intended for use either as stand-alone components of upper-air equipment or a germicidal system.
