Technically, a "fire exit door" is any door that leads to an exit discharge. Not all fire exit doors are required to have a fire rating or panic hardware or an out-swinging hinge. However, many fire exit doors are fire rated, meaning that they are expected to endure at least some amount of fire for a limited time. Also, some types of occupancies cannot have in-swinging doors anywhere in the egress path.
In the US, they are often made of wood or metal. Sometimes they are part of a firewall that is part of a fire rated corridor, and have a rating (such as 1-hour). Rated doors are solid wood or mineral filled metal doors, and are rated by a special agency.
An important part of exit doors are the direction of swing and special hardware that allows use in case of panic. Panic hardware for buildings with a large exit load includes a bar near waist height that unlocks the door when pressed from the inside. Some exit panic hardware has a built-in delay for security reasons.
Doors made of aluminum and glass are often used at the front of stores and offices. Glass used in a rated fire door assembly must also be fire rated.

Can you shorten internal fire rated doors?
Yes, you can shorten fire rated doors, but edges have to be re-lipped. Fire doors are tested to keep out fire for a set time (usually 30mins). A 24'' fire door will keep out the fire just as long as a 33'' door, its the construction that matters most, delaying fire going from front of door through to the otherside.
Should fire doors be closed at all times?
This is largely dependant on the security and convenience needs of the building. By code, Fire doors are to be equipped with automatic closers, and if mag-locks are installed to hold them open, they are to release upon activation of the fire alarm system to allow the doors to close properly. Some fire doors are equipped with fusible-links which break when subjected to a certain temperature, and therefore allow the fire door to automatically close, with the desired effect being containing the fire. Fire doors may remain open as necessary in non-fire situations, but must be unobstructed and maintained in working order at ALL times.
In the 1800's what did factory workers have to face?
Factory workers had minimal working space so if there was a fire you had to be in a single file line, two, there were no laws so if there was a fire there were no sprinklers or smoke detector's, and third there were guards at each exit so you couldn't still from the factory's so some doors were locked.

Does ac work better with doors closed?
Absolutely. If you leave the doors open, the air conditioner will need to work over capacity as you are allowing warm air into the area. As well as warm air entering, you are allowing the cooled air to exit. Having the doors open means that the air will not cool to the temperature you have set the air conditioner to, and it will be using far more electricity than it usually would with the doors closed.

What is a fire door?
a fire door is one term for an access to or from an emergency exit. A fire door is designed to keep smoke and fire from moving from one part of a building to another, and to provide a safe way to escape from a fire. Not all fire doors lead directly outside; some lead to stairs or horizontal passageways, which lead to an exit door, either outside or to a safe area. Fire doors are required for protection of any large openings in a fire wall that separates one part of a building from another. Some industrial fire doors are designed to slam shut during a fire and cannot be opened or used as an exit. There must be, of course, other fire doors that serve as exits. Fire and safety codes generally require that fire doors be of a self-closing type and prohibit propping open or obstructing a fire door for any reason.

Can exit doors be locked?
Most state laws make it illegal to lock exit doors if the building is occupied. The door does not have to allow people to come in through them, only to exit through through them. Even if there are "excess" doors available (e.g., 10 doors for 2,000 people and only 50 people inside, which could easily fit through one or two doors), ALL required fire doors must be properly illuminated, signed and operable regardless of how many people happen to be inside. In theory, a fire or other emergency could start in any part of the structure and every fire exit must be available for use by any untrained person inside. Trained personnel on a night shift, for instance, may allow all but two doors to be locked (or shuttered), because the training includes instructions on where the two open exits are.
How can you escape from a fire?
Find the safest possible exit. Always check doors for heat first, if its hot, don't enter that room.
Why do you have fire alarms?
Fire doors may serve more than one purpose. Many fire doors are part of a fire escape route, arranged so that in the event of a fire you can get out. Such exit fire doors may be a special kind of door that automatically unlocks when there is a fire. As a general rule, however, fire doors are designed to prevent or slow the spread of fire so that people can escape from a burning structure. For example, in a multi-story building it would not be safe to have open stairwells through which fire can easily spread from lower levels to higher levels, so engineers and architects specify self-closing fire doors for protection of stairwell access. The doors may be used for ordinary daily access to the stairs, or for access during an emergency evacuation, or both. Industrial fire doors, on the other hand, may be designed to slam shut during a fire and cannot be marked as a fire exit or used as a fire exit. Other fire doors serving as exits would also be provided.
Is it illegal to open a fire door when there is no fire?
It's not illegal no, Some people use the fire door in other emergencies. Many fire doors are also in everyday use, such as those separating parts of a building into different smoke or fire compartments, or protecting stairwells. Such doors are intended to be opened as necessary to pass through. However, it would be a code violation to prop open a fire door, which would defeat the purpose of automatic closing in case of fire. Some buildings may also have other security concerns that require exterior fire doors to remain closed except in an emergency. Such doors may have alarms or delayed exit latches to discourage misuse.
