Since 1969, NIST has investigated about 40 earthquakes, hurricanes, building and construction failures, tornadoes, and fires—all with the ultimate aim of identifying improvements in codes, standards, practices, and technologies.
Recommendations Resulting from Studies
- NIST Investigation of the May 22, 2011 Joplin, MO, Tornado Recommendations
- NIST Investigation of the Charleston Sofa Store Recommendations
- NIST Investigation of The Station Nightclub Fire Recommendations
- NIST Investigation of the World Trade Center Disaster Recommendations
Impacts of NIST Disaster and Failure Studies include:
The Station Nightclub Fire (2003)
- Requirements for automatic water sprinklers were changed significantly.
- The National Fire Protection Association (NFPA) changed the model building and fire code to require automatic water sprinklers in existing nightclub facilities with occupant loads greater than 100. It also required that all new nightclub facilities to be sprinklered. This was adopted in the 2006 editions of the codes.
- The International Code Council (ICC) changed the International Fire Code (IFC) to require assembly occupancies, such as nightclubs, to be sprinklered where occupant loads were greater than 100. (The previous requirement was greater than 300 occupants.)
- Adoption and enforcement of model codes.
- Strengthening of restrictions on foam plastic finish material.
- NIST is working with Underwriters Laboratories, ASTM, and National Fire Protection Association to conduct the research needed to support changes in building and fire codes and standards. This will be a long term effort as NIST works with multiple standards committees including UL 94, ASTM E84, NFPA 255 and NFPA 286.
- Strengthening of restrictions on use of pyrotechnics.
- Rhode Island strengthened restrictions to prohibit use of pyrotechnics in places of assembly including nightclubs.
- Increased factor of safety on egress.
- NFPA restricted festival seating in new and existing facilities if occupant load is greater than 250, unless life-safety evaluation is conducted (adopted in 2006).
- NFPA required trained crowd managers for existing and new assembly occupancies.
- Portable fire extinguishers requirement.
- Rhode Island now requires two 20-pound extinguishers in stage areas.
World Trade Center (2001)
- Changes to ICC Building Codes Consistent with Recommendations from NIST's WTC Towers Investigation (Approved at the Final Action Hearings of the International Code Council, May 2010)
- Changes to ICC Building and Fire Codes Consistent with Recommendations from NIST's WTC Towers Investigation (Approved at the Final Action Hearings of the International Code Council Minneapolis, Minn., September 15-21, 2008)
- Changes to the NFPA Building and Fire Codes Consistent with Recommendations from NIST's WTC Investigation (Approved at the NFPA Annual Meeting and Standards Council Action on 2009 Documents, July 2008)
