Final answer:
An owner of a restaurant does not need to employ a company with a commercial cooking exhaust system servicing company certificate if they have the knowledge and resources to perform the inspection and cleaning themselves.
Step-by-step explanation:
In order for an owner of a restaurant to not employ a company that possesses a commercial cooking exhaust system servicing company certificate, they must have the knowledge and resources to perform the inspection and cleaning themselves. This includes having the necessary equipment, expertise, and understanding of the applicable regulations and safety standards.
For example, if the owner of a restaurant is a trained chef who has experience working with commercial cooking exhaust systems and understands the maintenance requirements, they may choose to handle the servicing themselves without relying on a certified company.
