Fire Evacuation by Elevators

June 1, 1993
Author(s)
J H. Klote, Scott Deal, E. A. Donoghue, Bernard M. Levin, N Groner
There is a rising concern for the safety of persons from fire who cannot travel building emergency exit routes in the same manner or as quickly as expected of able persons. One proposed solution for providing safety for these people is the use of elevators

The control of quality in a comprehensive mass spectral library

May 30, 1993
Author(s)
Anzor I. Mikaia, S G. Lias, Stephen E. Stein
Computer generated "Quality Index" for the selection of spectra for the inclusion to the NIST/EPA/NIH mass spectral library is abandoned. We have undertaken a program to manually examine all spectra in the database. Suspect spectra are first examined to

Dynamics of the Release of Alternate Halon Replacement Agents From Pressurized Bottles

May 11, 1993
Author(s)
William M. Pitts, Jiann C. Yang, B D. Breuel, W G. Cleveland, G. Gmurczyk
Halon 1301 has been widely employed on military and commercial aircraft for fire fighting purposes. Unfortunately, due to the deleterious effects of chlorine and bromine on stratospheric ozone, the manufacture of halon 1301 will be phased out by the end of

Solubilities of Nitrogen and Freon-23 in Alternative Halon Replacement Agents

May 11, 1993
Author(s)
Jiann C. Yang, B D. Breuel, William L. Grosshandler
As part of the USAF-sponsored halon replacement project, solubility measurements of nitrogen and Freon-23 in eleven potential halon replacement agents and evaluations of the thermodynamic properties of the agents are currently being conducted at NIST. The

Structure of Inhibited Counterflowing Nonpremixed Flames

May 11, 1993
Author(s)
Anthony P. Hamins, M H. Yang, I K. Puri
Recent international agreements call for a halt to the manufacture of CF3Br (Halon 1301), a commonly used halon fire suppressant, due to its high ozone-depletion potential. Ideally, the search for replacement compounds should be guided by fundamental
