According to Justin McWilliams, what does "closed" signify in emergency terms?

In emergency terminology, the term "closed" is often associated with the concept of restricted access, meaning that certain areas or buildings are not accessible for safety reasons. This is typically implemented during emergencies to prevent individuals from entering places that could be hazardous. The term "closed" does not typically connote "open opportunities," as that would be contrary to the concept of restricting access for safety.

When considering terminology used in emergency situations, it is essential to understand that the primary goal is to protect individuals and manage risk, thus reinforcing why restricted access is an important interpretation of "closed."
