Some best practices for storing refrigerants safely include: storing refrigerant containers in a well-ventilated area, away from heat sources and ignition sources; ensuring containers are properly labeled and sealed; keeping containers upright and secure to prevent leakage or tipping; storing refrigerants in their original containers or approved equivalent containers; and maintaining a clean and organized storage area to prevent accidents and contamination. Additionally, HVAC professionals should regularly inspect refrigerant containers for signs of damage or leakage and follow proper procedures for handling and disposing of damaged or leaking containers.
