What code or guidelines (minimum size,location,etc) can I use for Fire Man's Access requirements for a high rise building.
Do you want to restate your question and add more detail.
Check 403.5.3. And 403.6.1
i do not think that answers your question.
Normally firefighters use the exit stairs
Some cities require some credit doors to be keyed on the outside and a lockbox with keys located somewhere on the building
HIGH-RISE BUILDINGS - ADDITIONAL EXIT STAIRWAY
The IBC has taken a different approach on the fire-fighter-civilian counter flow issue. In 403.5.2, the IBC now requires an additional exit stair way in high-rise buildings in excess of 420 ft (130 m) in height (over approximately 40 stories, assuming 10 ft (3 m) per story and 20 ft (6.1 m) for the ground floor), exclusive of apartment buildings. The intent is to allow one stairway to be used solely for firefighting operations, without adversely affecting the required exit capacity needed to egress the building occupants. The code intent is not to require a dedicated fire service stairway. Removal of any stair cannot reduce the required exit capacity needed to egress the building occupants, thus allowing the fire department to take control of the one stair best suited to support their operations for that particular emergency. It will be necessary for the fire department to manage evacuation flow to the remaining stairs. The apartment building exception takes into account the relatively low occupant loads associated with that occupancy, which should not significantly affect the counter flow in the stairways. The exception to the additional exit stairway is to provide occupant evacuation elevators in accordance with the new 3008, which is discussed later in this article.
