The only way I know to kill that kind of fire is by starving it of oxygen (some compounds like Halon are used in tanks for that purpose, people do not have time to suffocate since the fire is extinguished within seconds, when the system is "successful" <g>), but in a building, unless the fire is localized, it may involve suffocating people as well.

I expect a very thorough investigation will come up with some accurate answers to the structural situation on the WTC tragedy There was a PBS special awhile back looking at this very issue .. The WTC was built with a very strong exterior skin and central core, but the steel supports for the poured concrete slab floors were the weak link and could not withstand the heat generated from the burning jet fuel .. once one floor failed the slab dropped and pancaked every floor below and so forth .. There was also some examination of certain structural steel elements at the Fresh Kills Landfill in NJ where the wreckage has/is being transported, that exhibited failures attributed to the actual impacts of the hijacked jetliners .. Jim in Ct ..

Pearly Button..OT "I expect a very thorough investigation will come up with some accurate answers to the structural situation on the WTC tragedy." This man is well respected in the Fire Service in the US. He is recently retired having served in the New York City Fire Department for over 42 years.This attached link should provide some more answers. vincentdunn.com

hi PB, looks like the UK is trying to get it together in case of a nuclear attack or incident...this new document makes everything perfectly clear...just like American government documents on this subject. nrpb.org clip...This document sets out the Board's advice on intervention levels for food following a radiological accident. It replaces previous Board advice on this subject. The advice is given in the context of recent recommendations from the International Commission on Radiological Protection and of Regulations from the Council of the European Communities on intervention levels for food. The Board advises that the Council Regulations will restrict radiation doses from food to low levels. Reduction of the Council intervention levels to more restrictive levels is therefore unlikely ever to be justified on the grounds of reducing radiation risk. However, the Board advises that, following a very severe accident, it could be justified to relax the Council intervention levels by up to a factor of ten. For individual foods or radionuclides, where it could be demonstrated that individual doses would be restricted to levels of a few millisievert, a greater degree of relaxation could be justified. The Regulations do not specify levels for drinking water supplies. The Board has therefore recommended UK Action Levels for water. In circumstances where replacement of supplies is extremely difficult, relaxation of the Action Levels by factors of two or three may be justified. it is great that everything has been so well defined now... great advice...the board does not recommend you eat or drink anything exposed to high levels of radiation unless you have to...huh? or does it? i wonder what the previous board advice on this subject was? how many colors in your alert system? unclewest
