About UL 793
UL 793 is a standard that specifies requirements for the construction and performance of commercial kitchen exhaust hoods. This standard was developed by Underwriters Laboratories (UL), a globally recognized independent safety science company. UL 793 aims to ensure that kitchen exhaust hoods effectively capture and remove cooking fumes, grease, and other airborne contaminants.
Key Requirements of UL 793
UL 793 outlines various criteria that commercial kitchen exhaust hoods must meet in order to be certified. Here are some of the key requirements:
Construction: The hood structure should be made of non-combustible materials and designed to prevent condensation.
Efficiency: The hood must have a minimum capture and containment efficiency for grease and smoke particles.
Lighting: Adequate lighting is required to allow visibility for safe cooking operations.
Noise Levels: The hood should not produce excessive noise that may disrupt the working environment.
Fire Suppression: If the hood is equipped with fire suppression systems, they must comply with specific requirements regarding their design, installation, and maintenance.
