1 Scope

1.1 These requirements apply to ultraviolet germicidal irradiation (UVGI) equipment and systems emitting uncontained UV, 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. These requirements cover:

  1. a) Upper-room germicidal equipment – These devices emit UV energy into the surrounding area while the space being treated may be occupied. The UV overexposure risk is mitigated by a fixed installation at a minimum height above the floor as well as directional baffling to minimize direct UV emissions towards the occupied space. This equipment may also produce visible light. See Part I of this document.

  2. b) UV emitter assemblies – These devices emit UV energy into the surrounding area while the space being treated is vacant (i.e.: not occupied by persons). Alternatively, these devices can be built into germicidal equipment as components. These are not considered stand-alone devices; they are intended for use as part of a UV germicidal system. This equipment may also produce visible light. See Part II of this document.

  3. c) UV germicidal systems – These devices are 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. See Part III of this document.

  4. d) UV germicidal retrofit kits – These devices are retrofit kits which facilitate replacement of the light source of a General Lighting Service (GLS) luminaire with a UV LED emitter assembly. These retrofit kits emit UV energy into the surrounding area while the space being treated may be occupied. The UV overexposure risk is mitigated by the exclusive use of UV LED sources that are classified as ‘risk group exempt’ in accordance with the Photobiological Assessment for the device. The UV LED source may also produce visible light. See Part IV of this document.

1.2 These devices are intended for commercial and industrial environments. These requirements do not cover:

  1. a) Equipment intended for use in dwellings; or

  2. b) Hand-held or portable equipment.

1.3 Products generating ultraviolet radiation are intended for use in accordance with Title 21 Code of Federal Regulations (CFR) Parts 1000 through 1004, and section 1005.25.

Note: These regulations include reporting of Accidental Radiation Occurrences, notification to FDA and customers of a radiation safety defect and corresponding plan for corrective action for FDA approval, and designation of a U.S. agent for imported lamps.

1.4 This outline of investigation does not apply to UV equipment covered by other (UL/ CSA) standards for safety. The equipment not covered by this Standard include:

  1. a) Laboratory and health care equipment with UV emitters are covered under the scope of UL 61010 and CSA-C22.2 No. 61010, “Electrical Equipment for Measurement, Control, and Laboratory Use;” and

  2. b) Horticultural luminaires with UV emitters covered under the scope of ANSI/CAN/UL 8800, “Horticultural Lighting Equipment and Systems.”

1.5 Equipment that emit electromagnetic energy with wavelengths outside of the 200 – 700 nm range are not fully addressed by this outline of investigation, and may require an additional evaluation.

1.6 These requirements address risk of personal injury due to overexposure to UV emissions. To address other safety considerations (e.g.: risk of fire or electric shock, or personal injury risks besides UV overexposure) this outline of investigation shall be used in conjunction with one of the luminaire standards noted below for devices covered in their respective scopes absent electromagnetic emissions outside of the visible light spectrum. All construction, performance and marking requirements of the standards noted below shall also apply unless specifically superseded by a requirement in this outline of investigation:

  1. a) The standard for luminaires, CSA C22.2 No. 250.0 / UL 1598; or

  2. b) The standard for low-voltage lighting systems, CSA C22.2 No. 250.2 or UL 2108.

1.7 In this outline of investigation, the CSA standard reference applies to products intended for use in Canada, while the UL standard reference applies to products intended for use in the United States. Combined references are commonly separated by a slash (“ / ”).
