Combustible Fuel Loading on Floors 11 and 12

COMMENT: This comment relates to NIST’s assumptions regarding combustible fuel loading for the 11th and 12th floors. In NCSTAR 1-9, at p. 375 (para. 1, sent. 7-9) NIST states:

NIST assumed that the combustible mass of furniture was about the same in an office as in a cubicle. Since the loading of other combustibles was reported to have been high on the 11th and 12th floors (Chapter 3), NIST assumed that the total combustible mass in an office was double that of a cubicle. Thus, the average combustible fuel load on the 11th and 12th floors was estimated as 32kg/m2.

However, Chapter 3 tells us that, contrary to NIST’s assertions in Chapter 9, the loading of other combustibles was not reported to have been high on the 11th and 12th floors. On page 55 (para. 6, sent. 1) of NCSTAR 1-9, NIST reports that the U.S. Securities and Exchange Commission occupied the 11th and 12th floors and the north side of the 13th floor. On page 56 (para. 1, sent. 1) NIST further reports that American Express occupied the southwest sector of the 13th floor. On the same page, NIST reports that the “combustible load in the offices was described as high by interviewed American Express managers.” (NCSTAR 1-9, p. 56, para. 4, sent. 3)

REASON FOR COMMENT: Recall that American Express occupied only the southwest sector of the 13th floor. How, then can NIST credibly claim that the combustible load on the entirety of the 11th and 12 floors, both occupied solely by the SEC, was reported to have been high? Were American Express managers given regular access to the SEC offices, such that they would be qualified to comment on the combustible fuel load there? Moreover, are American Express managers qualified to give an opinion on the quantity of combustible fuel load as compared to offices in the Twin Towers?

SUGGESTED REVISION: Clearly American Express personnel are competent to provide information only on the state of the American Express offices, which were confined to the southwest sector of the 13th floor. NIST must provide real support for its assertion that the combustible load on the 11th and 12th floors was high in order to merit any increase in estimated average combustible fuel load on these floors. If it cannot provide such support, it should re-run its computer models with the lower combustible fuel load on these floors and report those results to the scientific community and the American public.

Ok, even mag, als je nu maar die mening van je gaat geven.
Anders is het echt een enorme zwaktebod en zul je moeite hebben om voortaan serieus over te komen.

Als het klopt wat men hier claimt, dan heeft NIST gewoon aannames gedaan en dus niet bij legtieme bronnen gechekt of deze claims kloppen. Echter, als ik het NIST rapport er op na sla, dan kan ik het volgende niet vinden:

Op die pagina staat, voor zover ik kan zien geen enkele zin waaruit blijkt dat ze American Express Managers hebben geïnterviewd:

Weet iemand of NIST inmiddels een herziene uitgave heeft, die ik nu dus aan het lezen ben? Het lijkt hier i.i.g. om een typo te gaan.

Dus daar waar "American Express" managers zou staan volgens de claim, had moeten staan: "SEC managers" en dat staat er nu dus ook.

Iemand die ziet of ik nu een fout maak?
