Before using a gas cylinder, what is a critical check to perform?

Verifying that the regulator is suited for the gas type is critical before using a gas cylinder because different gases have distinct properties and pressures that require specific regulators designed to handle them safely. Using an incompatible regulator can lead to improper gas delivery, malfunction, leaks, or even accidents, depending on the nature of the gas. Regulators are designed to control the pressure and flow rate of the gas, so matching the regulator with the appropriate gas ensures the device will function safely and effectively.

While other checks, such as confirming the most recent inspection date or matching handling procedures, are important for overall safety and compliance, ensuring the correct regulator for the specific gas type is paramount as it directly relates to the safety and efficacy of the gas delivery system. Choosing the wrong regulator might lead to serious safety issues regardless of the cylinder's condition or conformity to handling procedures.
