Some places of mass public interest will usually have Fire Wardens or other people trained to deal with the event of a fire. I - for one - am trained in such tactics where I work and our responsibilites are helping people from the building if a fire were to break out, man fire exits to mark them clearly to people evacuating the building and fight the fire if we are in no way of putting our own safety at risk. The obvious reason we do this is a good measure to the general public and colleagues. We obviously don't want the responsibility of dead people on our hands. To learn that a hotel wouldnt adopt such an attitude to safety is shocking. In terms of legality, as long as the fire alarm has being sounded the hotel staff do not need to do anything else. It is then on that the people staying in the hotel will be responsible for there own safety. There is the obvious arguement that the people won't be able to hear the alarm because they are sleeping but part of the conditions of building a hotel is having a fire alarm that can be heard from each room above a certain decibel level. What the exact level is I dont know. Sorry if its dragged out this answer but I hope ive helped!
