Upblast fans should drain into a grease receptacle with capacity not exceeding how many gallons?

• A. Not exceed 5 gallons
• B. Not exceed 1 gallon
• C. Not exceed 2 gallons
• D. Not exceed 0.5 gallons

Answer: (B)

Upblast fans deal with hot, grease-laden air, and any grease that collects in the drain path becomes a potential fire fuel. Limiting the grease receptacle to a small capacity means it has to be emptied and serviced frequently, so grease doesn’t build up and create a fire hazard or spill into the ductwork. A small container also makes inspection and cleaning easier and helps keep the system within safety and maintenance guidelines. If the receptacle were larger, more grease could accumulate, increasing fire risk and making maintenance more cumbersome, with a higher chance of overflow during busy periods. A very tiny receptacle would be impractical due to constant servicing, but the standard practice aims for a limited capacity to minimize grease load and support safe, regular maintenance.
