46. When a notable event occurred, it was standard procedure for the on-duty deputy fire safety director to make an "advisory" announcement to tenants who were affected by or might be aware of the incident, in order to acknowledge the incident and to direct tenants to stand by for further instructions. The purpose of advisory announcements, as opposed to "emergency" announcements (such as to evacuate), was to reduce panic.

88. For the callers, see Commission analysis of 911/PAPD calls.There are many variables to consider in determining whether, and to what extent, stairwell A was actually a viable exit. Knowing that the stairway was initially passable from at least the 91st floor down, we can conclude that it was likely open from top to bottom, on floors farther removed from the impact. However, in areas near the impact zone some doors leading to the stairwell may have jammed.We know that access to stairway A was possible from at least the 81st and 84th floors, and from several other floors between the 84th and 91st floor. It is likely that access was possible from floors higher up as well. It is not known, however, whether 911 callers had a clear path to the stairwell entrance from their locations. Damage caused by the impact of the plane, and the resulting smoke and heat, may have prevented some from being able to reach the entrance to the staircase; but the stated locations of at least some callers indicate that they were near stairwell A on their floor. Based on conditions described by civilians who descended stairwell A from at or above the impact zone, we conclude that stairwell A may have become effectively impassable as the morning progressed.

It is unknown whether the lobby chief ceased to communicate on the repeater channel because of technical problems or because he simply switched channels in order to be able to communicate with chiefs outside the South Tower.The FDNY strongly maintains that there must have been a technical problem resulting from the impact of one of the planes, because they do not believe this chief would have switched channels without first so advising on the repeater channel. FDNY letter to the Commission, July, 2, 2004. However, the repeater channel subsequently worked very well for FDNY personnel on the 78th floor and in an elevator on the 40th floor.

190.The Incident Command System (ICS) is a formalized management structure for command, control, and coordination during an emergency response. ICS provides a means to coordinate the efforts of individual agencies as they work toward the three main priorities of most emergencies-life safety, incident stability, and property/environment conservation.Within ICS, incident command is organized into five major components: the command function, the planning section, the operations section, the logistics section, and the finance/administra-tion section.When multiple agencies or jurisdictions are involved in a response, ICS provides for and can evolve into a unified command, with a decisionmaker from each key agency represented at the incident command level. For the system being used on 9/11, see, e.g., Arlington County,Virginia, report,Titan Systems Corp., "Arlington County: After-Action Report on the Response to the September 11 Terrorist Attack on the Pentagon," 2002, pp. 11, A-20-A-21.

200. For the estimate, see NIST report, "WTC Investigation Progress," June 22-23, 2004. For the updated death certificate information, see New York City report, "WTC Victim List," June 21, 2004.The analysis in this paragraph is based upon the following sources: CNN, "September 11: A Memorial," updated 2004 (online at www.cnn.com/SPECIALS/2001/memorial/index.html); company contacts, June 29, 2004 (online at http://worldtradeaftermath.com/wta/contacts/companies_list.asp?letter=a); CNN, WTC tenants, 2001 (online at www.cnn.com/SPECIALS/2001/trade.center/tenants1.html); September 11 personal tributes, June 19, 2004 (online at www.legacy.com/LegacyTribute/Sept11.asp); September 11 personal profiles, Oct. 11, 2003 (online at www.september11victims.com/september11Victims); New York Times, Portraits: 9/11/01:The Collected "Portraits of Grief" (Times Books, 2002). It is possible that a person who worked above the impact zone had not yet reached his or her office and was killed below the impact zone, either by falling debris, by the fireballs that exploded into the lobby, or by being trapped in an elevator. Individuals below the impact zone may have been killed for the same reasons. Individuals may also have been killed while in the process of evacuating.
201. Ironically, had the towers remained up longer, scores more first responders would have died.Twenty-six additional FDNY companies-more than 150 firefighters-were en route at the time of the South Tower's collapse, and scores more PAPD officers on Church and Vesey were preparing to enter the towers.
202.The "advisory" announcement directed by protocol (without the expanded instruction for occupants to return to their floors) would have given greater leeway to those who judged, based on a firsthand awareness of conditions on their floors (e.g., some could feel heat from North Tower explosion), that evacuation was warranted. In retrospect, occupants would only have had to reach a point below the 77th floor to be safe.
203.Appended to the directive was a list of different types of emergencies with designated Incident Comman-ders.Terrorist incidents were subdivided according to the types of attack. Conventional weapons and bomb threats were assigned to the NYPD, while chemical, biological, and nuclear attacks designated "NYPD or FDNY" as the Incident Commander.The directive noted:"The handling of a threat of a chemical or biological release or the use of conventional weapons falls to the NYPD. Dealing with the consequences of the explosion or release is the responsibility of the FDNY.The investigation that follows, once the consequences of the event have been mitigated, is the responsibility of the NYPD. Any conflicts regarding the issue of Command at these incidents will be resolved by OEM." New York City memo, Office of the Mayor, "Direction and Control of Emergencies in the City of New York," July 2001.
204. For the NYPD clearing lanes, see, e.g., FDNY interview 43, Chief (Mar. 3, 2004).
205. For the Mayor and Police Commissioner's consultation with the FDNY Chief of Department, see Rudolph Giuliani interview (Apr. 20, 2004).
206.The FDNY's lack of command and control had some unintended positive consequences. One battalion chief was dispatched to the South Tower but instead responded to the North Tower, where he was instrumental in saving many lives after the South Tower collapsed. Some FDNY units dispatched to the South Tower-where they would have perished-instead were mistakenly sent to the North Tower and in many cases survived.
207. For the FDNY addressing these issues, see generally FDNY report, McKinsey & Company, "FDNY Report," Aug. 19, 2002; Peter Hayden interview (Jan. 14, 2004). For the PAPD not changing standard operating procedures or training, see PAPD regulations,"Manual of Police Division Instructions," undated (in existence before and after 9/11); Barry Pickard interview (Nov. 24, 2003).
208. One instance in which the FDNY/NYPD rivalry may have had an impact on the total fatalities was the alleged failure of ESU officers descending past at least two firefighters after 9:59 in the North Tower to share their evacuation instructions. It should be noted, however, that at least one firefighter has conceded that he, too, descended past other stationary firefighters without telling them to evacuate. In addition, according to one of the ESU officers and one of the firefighters in the North Tower, at least some FDNY personnel were unwilling to take evacuation orders from police that morning.
209. Based on more than 100 interviews we conducted and our review of 500 internal FDNY interview transcripts, we conclude that out of these 32 companies, all on-duty members of 19 companies are likely to have known to evacuate (Engine Companies 1, 4, 7, 9, 15, 16, 21, 24, 28, 33, 39, and 65; Ladder Companies 1, 5, 6, 8, 9, 110; and Rescue 1).We also conclude that at least some members of each of five companies knew to evacuate (two firefighters from Ladder Company 10; the officer of Ladder Company 20; all but the officer of Engine Company 10; at least two firefighters from Squad 18; and at least three firefighters from Engine 6).We do not know whether members of the eight other companies knew to evacuate (Engine Companies 55, 207, and 226; Rescue 2, 3, and 4; Hazmat 1; and Squad 1) because they all died, and we have come across no on-point eyewitness accounts related to their operations. It is very possible that at least some of these firefighters did hear the evacuation order but nevertheless failed to evacuate in the only 29-minute period between the collapse of the two towers. In addition, it is possible that several of the eight companies for which we have no record of their receiving evacuation instructions were in the South Tower and thus died in its earlier collapse.
