CO₂ 110 – CO₂ Refrigerant Safety

Build a safe foundation for working with CO₂ refrigeration systems.

Focuses on safety considerations unique to CO₂ (R‑744) refrigeration systems.

Overview

Carbon dioxide (CO₂) refrigeration systems operate at pressures significantly higher than traditional ammonia or HFC systems. These pressures, combined with CO₂’s physical properties, introduce unique safety considerations for operators, technicians, and engineers.

This course introduces the hazards associated with CO₂ refrigeration systems and explains how proper system design, controls, and operating procedures mitigate risk. Emphasis is placed on understanding pressure, leaks, and personnel safety.
