Under what condition does a restaurant owner not need to employ a certified commercial cooking exhaust system servicing company?

A restaurant owner does not need to employ a certified commercial cooking exhaust system servicing company if they have a W-64 Certificate holder. The W-64 Certificate is a specific certification that indicates that the individual has been trained and is qualified to perform maintenance and service on commercial cooking exhaust systems in accordance with safety standards. This certification provides the necessary assurance that the person handling the system is knowledgeable about the regulations and requirements for proper servicing.

Options that suggest self-cleaning or less frequent use of the system do not create exemption from the requirement of hiring certified professionals, as regular maintenance and compliance with safety codes are essential regardless of the cooking frequency or who performs the cleaning. The presence of a licensed contractor, while important, does not fulfill the specific criteria set forth for commercial cooking systems unless they also hold the W-64 certification. Therefore, the condition regarding the W-64 Certificate holder is the most directly related to ensuring compliance with safety regulations.
