If hospital got fire. what to do as hospital staffs?

Hospitals are constructed as "protect in place" buildings which means they have fire/smoke walls and doors that separate sections of the building from each other. Each barrier can protect the space on the other side for up to 2 hours with a fully engulfed fire giving the staff time to evacuate their patients to a safe area. However, this should not be necessary in most hospital as they are also fully sprinklered. Correctly operating sprinklers will put out a fire within 2 minutes. Most fire departments will respond within 4 minutes but the fire will most likely be out by then. Each patient room is protected from an adjacent fire by sheetrock and special doors which will keep a raging fire from affecting them for at least 20 minutes. Also well after a typical fire would be put out in a sprinklered area. Hospital staff would rescue the patient from the room with the fire and close the door to keep the smoke and fire contained within that room. All other patient room doors would be closed as well to protect them from smoke that might have already escaped the fire room before it was closed off. If necessary they would evacuate their patients and staff to the next fire compartment and wait for the fire department to respond. In any building, always close all the doors behind you to protect you from the smoke, which is more dangerous than the fire. Modern furniture and products give off toxic chemicals when they burn.
