What is the safe working pressure for Acetylene?

The safe working pressure for acetylene is established at 15 psi. This value is critical for the safe handling and use of acetylene in various applications, particularly in welding and cutting operations. Exceeding this pressure poses risks, including the potential for explosions or other hazardous situations due to acetylene's instability when subjected to high pressures. The 15 psi limit is based on acetylene's behavior under pressure, ensuring that it remains stable and reduces the risk of decomposition or explosive reactions, which can occur if the pressure exceeds the recommended threshold. Therefore, recognizing 15 psi as the safe working pressure is essential for maintaining safety in environments where acetylene is used.
