Wastes hotter than which temperature should be discharged into a cooling basin or sump?

• A. 120 Degrees Fahrenheit
• B. 140 Degrees Fahrenheit
• C. 160 Degrees Fahrenheit
• D. 180 Degrees Fahrenheit

Answer: (B)

Hot wastes must be cooled before entering the general waste system to protect equipment, piping, and the treatment process, and to reduce hazards to workers. The chosen cutoff is 140 degrees Fahrenheit because liquids hotter than this are energetic enough to cause damage and safety concerns, so they’re directed to a cooling basin or sump to bring them down to a safer temperature before discharge. Discharging above this threshold without cooling could strain pumps and pipes and disrupt downstream processes, while using a lower cutoff would lead to excessive cooling for many wastes that aren’t actually dangerous. Higher cutoffs would allow even hotter liquids to go through without cooling, creating more risk.
