Core Fundamentals
- Ask what contaminant is being removed, where it is captured, and where it is discharged.
- Exhaust systems often become life-safety or fire-protection systems when contaminants are flammable, greasy, dusty, or toxic.
- Discharge location, makeup air, dedicated duct routing, and interlocks drive many corrections.
