When securing an oxyacetylene cutting outfit for an extended period, you should close the _______________.
AI Explanation
The correct answer is A) close the cylinder valves and close torch valves when pressure in hoses and regulators is zero.
When securing an oxyacetylene cutting outfit for an extended period, it is important to ensure that the system is completely depressurized. Closing the cylinder valves and torch valves when the pressure in the hoses and regulators is zero ensures that no residual pressure remains in the system, which could pose a safety hazard. This is the recommended procedure to safely store the equipment.
The other options are incorrect because: B) maintaining 4-5 pounds of pressure in the hoses is not the recommended practice for long-term storage, C) closing the cylinder valves only is not sufficient, and D) closing the hand valves on the torch alone does not address the need to depressurize the entire system.
