Is the term "Break Glass Policy" or "Break Glass Procedure" used outside the healthcare field?

I don't work in the healthcare field and I've never heard those terms before, but I can guess* what they mean. If used in a formal context, it might be best to define them the first time, as the avoidance of ambiguity is very important when it comes to fire alarms and emergencies. However, it may be better just to avoid these terms, especially as there's no results at all in http://books.google.com/ngrams/graph?content=break%20glass%20policy,break%20glass%20procedure,Break%20Glass%20Policy,Break%20Glass%20Procedure,Break%20glass%20policy,Break%20glass%20procedure&year_start=1800&year_end=2011&corpus=0&smoothing=3: Furthermore, there are only about 1,190 results for http://www.google.com/search?q=%22break%20glass%20policy%22 and only about 400 results for http://www.google.com/search?q=%22break%20glass%20procedure%22, so these terms are not used much anywhere. I would expect higher results even if they were widely used by the healthcare field. * After checking one of the links, my guess was wrong: I assumed it was the policy for evacuating people out in an emergency, but "refers to a quick means for a person who does not have access privileges to certain information to gain access when necessary".
