AWS Welding Inspection and Testing Certification Practice Test

Where should oxygen cylinders be stored in relation to flammable gases?

1. With flammable gases in the same storage area

2. Next to flammable gases

3. Separated by a brick wall or a safe distance

4. In the same equipment case

The correct answer is: Separated by a brick wall or a safe distance

Storing oxygen cylinders requires strict adherence to safety protocols given the potential risks associated with their interaction with flammable gases. The correct approach is to keep oxygen cylinders separated from flammable gases by either a significant safe distance or a physical barrier such as a brick wall. This is crucial because oxygen supports combustion; even without an open flame, the presence of oxygen can significantly increase the risk and intensity of a fire if flammable gases are nearby. Having oxygen cylinders stored with or in close proximity to flammable gases can lead to hazardous situations. For example, if a flammable gas were to leak, the elevated oxygen environment could ignite the gas more readily, leading to potential explosions or fires. Therefore, maintaining a safe separation helps prevent such dangerous incidents by ensuring that any flammable materials are kept at a distance from oxidizing agents, thereby reducing the risk of accidental ignition and ensuring a safer working environment.
