How should gas cylinders be stored to ensure safety?

Gas cylinders should always be stored in an upright position, secured to prevent tipping, and away from heat sources to mitigate the risk of fire or explosion. Storing cylinders upright is crucial as it ensures that the pressure relief devices function correctly and prevents the release of gas, which could happen if they are laid down or positioned improperly. Securing the cylinders helps to avoid accidents where they can fall or roll, potentially leading to dangerous situations. Additionally, keeping them away from heat sources is vital, as many gases are flammable or can become hazardous under high temperatures, which can lead to increased pressure within the cylinder and a risk of rupture. This set of guidelines helps to create a safe environment when dealing with potentially dangerous materials like medical gases.
