What is UL 762?

UL 762 is a technical standard established by Underwriters Laboratories (UL), an American safety consulting and certification company. It specifically focuses on the safety requirements for commercial hoods used in cooking establishments, such as restaurants and cafeterias.

The Purpose of UL 762

The main purpose of UL 762 is to ensure that commercial hoods effectively capture and remove grease-laden vapors, smoke, and odors generated during cooking processes. It sets standards for design, construction, performance, and testing of these hoods with the primary objective of minimizing fire hazards within the cooking environment.

Key Requirements of UL 762

To meet the UL 762 standard, commercial hoods must comply with specific criteria. These criteria include the hood's airflow capacity, minimum capture efficiency, proper filter installation and maintenance, and adequate clearance distances from combustible materials. The standard also covers electrical requirements, such as motor ratings, wiring, and controls, to ensure safe operation.

Compliance and Certification

Cooking establishments can demonstrate compliance with UL 762 by installing commercial hoods that are certified by recognized testing laboratories. Typically, hoods that meet the UL 762 standard will bear the "UL Listed" mark or an equivalent certification mark. Regular inspections and maintenance of the hoods are necessary to maintain their safety and compliance with the standard.

In summary, UL 762 is a technical standard developed by Underwriters Laboratories to ensure the safety of commercial hoods in cooking establishments. It establishes requirements for the design, construction, and performance of these hoods to minimize fire hazards. Compliance with UL 762 can be demonstrated by installing certified hoods and conducting regular inspections. By adhering to this standard, cooking establishments can create a safer environment for their employees and customers.
