Al Jazeera has put together a map showing the main code red and blue hospitals in the US.

The hospital code red code is the largest of the three codes and covers hospitals that are accredited by the Occupational Safety and Health Administration (OSHA).

It is a sign of a hospital that is in good health.

However, OSHA’s red codes mean that the hospital is considered unsafe and should be inspected.

The code blue code is for hospitals that have been certified by an independent third party such as an ambulance service, and have been inspected by OSHA.

Code blue hospitals are more likely to have experienced some sort of fire or explosion.
