@refrigerationmentor: The Introduction to CO₂ course has started, but there’s still time to join. Reserve your spot today. Learn more below ⬇️⬇️⬇️ When a CO₂ relief valve opens, where is that refrigerant going? The relief valve protects the system. The discharge path protects people and the building. CO₂ should not be released into an unsafe location because it can displace oxygen and create a serious hazard. Before assuming the system is safe, trace the discharge path. Where does it terminate? Is it outdoors? Is it away from people? Can anything block it? On CO₂ systems, relief piping is not just a piping detail. It is a safety detail. #RefrigerationMentor #refrigeration #co2 #gonatrefs #hvacr #commercialrefrigeration #supermarketrefrigeration #refrigerationtraining #refrigerationtechnician
