What should be done if an oxygen cylinder falls over?

If an oxygen cylinder falls over, it is crucial to wait at least one hour before using it. This is because when the cylinder goes horizontal, the liquid oxygen inside may have been disturbed. Liquid oxygen can create a highly flammable environment, and when the cylinder is back in an upright position and the gas resumes its normal state, there might still be residual liquid or pressure issues that need to be normalized. Waiting allows for the cylinder to stabilize, preventing potential hazards during operation. It’s essential for safety to ensure that the cylinder is used properly and that any risks associated with the fall are mitigated.
