What is the required minimum width for grease duct reservoirs?

The required minimum width for grease duct reservoirs is 12 inches. This dimension is established to ensure that the reservoirs can efficiently accommodate the accumulation of grease and operate effectively within the ventilation system. A width of 12 inches allows for proper drainage and maintenance, minimizing the risk of grease buildup and potential fire hazards.

Having a reservoir that is too narrow may lead to inadequate capacity for the expected volume of grease, which can impede the system's operation and increase the risk of fire due to grease ignition. Thus, 12 inches is the minimum width specified to ensure safety, functionality, and compliance with the applicable code requirements for grease handling in mechanical systems.
