What is a crucial safety measure when handling acetylene and oxygen cylinders?

Ensuring that acetylene and oxygen cylinders are secured in a vertical position and away from sparks is essential for maintaining safety during their handling and use. When cylinders are stored upright, it prevents the risk of them falling over, which could lead to dangerous leaks or ruptures. Furthermore, storing them away from sparks minimizes the chances of ignition, as both acetylene and oxygen are highly flammable gases.

This combination of securing the cylinders and preventing exposure to sparks is critical in reducing the risks of fire or explosion, which can have catastrophic consequences. Proper handling and storage practices are fundamental in ensuring the safety of personnel and maintaining a safe working environment.
