In March 2024, the ISO Technical Committee (TC) 92 Fire Safety, published “ISO 6021:2024 – Firebrand generator.” The ISO firebrand generator is based on the firebrand generator developed by CI members Samuel L. Manzello (Tohoku University, Japan and Reax Engineering, USA) and Sayaka Suzuki (Tokyo Institute of Technology, Japan). The firebrand generator is a combustion device that affords the ability to develop continuous firebrand showers seen in wildland-urban interface (WUI) fires, wildland fires, and urban fires. The ISO firebrand generator is a laboratory-scale version of the full-scale firebrand generator developed for large-scale experimentation, also developed by Manzello. These technologies are colloquially known as the Dragon. Firebrand showers are a main driver of fire spread in large outdoor fires. The ISO Firebrand Generator represents the first and only internationally accepted harmonized device for generating firebrand showers.
The ISO firebrand generator, installed in a wind facility, is being used to study how firebrand showers interact with an obstacle (0.6 m high by 1.2 m wide) placed downstream. The applied wind speed is 8 m/s.
The ISO firebrand generator, installed in a wind facility, is being used to study the ignition of a Noble-fir tree (1.2 m high). The applied wind speed is 3 m/s.
The International Organization for Standardization (ISO) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. ISO was founded on 23 February 1947, and it has published numerous international standards covering almost all aspects of technology and manufacturing. As of 2024, ISO has 170 national members. In ISO, Fire Safety is handled by TC 92.
