Hospital are places everyone visits (or at least should visit) often, and it is important to be aware of the codes and alerts that may be said in case of an emergency. Most of the codes are standardized but there are some that vary depending on the institution.
Standard Codes
Code Blue
An adult is suffering a cardiac or respiratory arrest. Examples of this could be a heart attack or choking. Anyone can help as far as they are CPR certified but it is better to open a path for hospital staff to attend it.
Code Red
It is the code for fire or smoke detected on the building. Staff will attend to the fire, please evacuate the building calmly but quickly.Do not use the elevator, use the stairs. Help anyone exit the building if they require it. If it is you who indetifies the fire first, please do shout code red and pull the fire alarm to notify the rest of the building and firefighters.
Code Orange
Most commonly a hazardous material spill. Usually a chemical one, but could also be biological, or in extreme cases radioactive. Please evacuate the area if you haven't come into direct contact with the chemical. Look for the closest shower to avoid any remnants if you actually came into contact. Follow up with your doctor days after to diminish chances of poisoning.
