Who probably is the audience of this talk?

Hello, I’m Bob First from the city fire department. I’ve been asked to review the emergency evacuation procedures for all hospitals in the area. If there is a fire in your building, this information could save your life and the lives of those under your care. In the event of a fire, the first thing you need to do is turn on the fire alarm by pulling down on this white bar, and this will alert the fire department. Along with the alarm bell that you will hear, you will also see flashing strobe lights that are activated in every unit when the alarm is turned on. If you see these lights or hear the alarm bell, it is essential to close all doors and windows to keep smoke and fire from spreading. Evacuate the patients who can’t walk first, then help the others out of the building. The fire department will have ambulances sent to your building so you can transfer any sick or injured people to another medical facility immediately. Now I want to outline each of your specific fire response duties.
