What is the maximum allowable grease discharge at the exhaust outlet of the system in mg by m3/m3 of exhaust air sampled?

The correct value for maximum allowable grease discharge at the exhaust outlet of the system is 5 mg/m³. This specification is significant because it establishes a standard for limiting grease emissions from commercial cooking operations. The NFPA 96 outlines this standard to mitigate the risk of fire hazards associated with grease buildup, which can ignite if not managed properly.

Exceeding this limit could indicate insufficient ventilation, inadequate cleaning practices, or the use of cooking equipment that produces excessive grease. Therefore, the regulation serves to protect not only the equipment and facility from the hazards of grease fires but also to ensure the safety of employees and patrons in and around the cooking areas.

Maintaining grease discharge levels at or below this limit is essential for compliance with fire safety measures and contributes to a safer operational environment in commercial kitchens.
