| Why it matters | Chapter 11 controls refrigerant hazards by tying refrigerant type, occupancy, system classification, charge amount, machinery room design, piping, and testing together. |
| In the field | This chapter shows up in comfort cooling, walk-ins, process refrigeration, supermarkets, and machinery rooms where the refrigerant itself drives life-safety design. |
Core Fundamentals
- The big idea is classification: refrigerant type plus occupancy plus system probability equals the rule set.
- Machinery rooms, detectors, discharge, relief routing, piping methods, and testing are the usual field checkpoints.
- Flammable or toxic refrigerants quickly move this chapter into fire-code territory.
