The oxygen regulator gauge is marked with a warning color above the 15 psi point.

Explanation:
Understanding oxygen regulator gauges: the low-pressure output is designed for safe welding work up to about 15 psi. There isn’t a built-in warning color that starts above that point, because normal operation should never exceed the 15 psi working pressure. If the gauge ever shows more than 15 psi, that indicates a fault or misreading, not a normal condition. So the statement is never true in proper use.
