[location of the OH hole]

No.

OH.

Even where it is intact, the OH shield isn’t 100 percent impenetrable. There are some chemicals that don’t interact as much with OH, and a small portion of them don’t get filtered out. They are able to make it through into the next atmospheric layer, the stratosphere. Some of these chemicals — including halons, methyl bromide, and chlorofluorocarbons (CFCs) — are known to break down ozone. And because they degrade very slowly, generally over the course of years, they have time to spread out over the entire globe, depleting ozone in the upper atmosphere and contributing to the polar ozone holes.
