Porté:

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.

These requirementscover:

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.

Raison d’être du projet

To establish requirements for equipment and systems that use ultraviolet (UV) energy primarily for UV germicidal applications. Mitigation of the UV overexposure risk to humans would be accomplished by a combination of site and equipment safeguards. UV emitter assemblies and germicidal systems are intended for use only in unoccupied spaces. A combination of switches, sensors and other controls act to ensure that the treated space is vacant before the system can be engaged, and also ensures that the space remains vacant for the duration of the treatment cycle. The effectiveness of these safeguards is confirmed by a safeguard assessment. This proposal is intended to address the personal injury considerations from UV overexposure, but it would be used in conjunction with the Canadian Luminaire standard, CSA C22.2 No. 250.0, to address the fire and shock considerations for the upper-room equipment and UV emitter assemblies.

Le système permet aux organismes d’élaboration de normes (OEN) accrédités par le CCN et aux membres du public d’être informés des nouveaux travaux d’élaboration de normes au Canada. Il donne aussi aux OEN accrédités la possibilité de repérer et de résoudre les cas de doubles emplois éventuels dans les normes et les travaux de normalisation.
