Ultraviolet hoods shall be tested and listed in accordance with ______.

Ultraviolet hoods shall be tested and listed in accordance with ______.

• A. UL 510
• B. UL710 or equivalent
• C. UL 1479
• D. ISO 9001

Answer: (B)

Ultraviolet hoods must meet a recognized safety standard to ensure they are designed, constructed, and installed without exposing workers to UV energy and without electrical or mechanical hazards. Ultraviolet hoods are specific equipment that combines electrical components and UV lamps in a ventilation environment, so they need independent testing and listing. UL 710 covers ultraviolet lamp fixtures and associated equipment used in air handling and similar applications, setting requirements for electrical safety, construction, shielding, and compatibility with ductwork. That’s why UL 710 or an equivalent recognized standard is the appropriate basis for listing. Other options don’t address UV lamp fixtures or ventilation-specific safety, such as UL 510 (gas-fired appliances), UL 1479 (firestop systems), or ISO 9001 (quality management), so they aren’t applicable here.
