International Fire Service Information Center (IFSIC) was established on April 1, 1996
under direction of the Fire and Disaster Management Agency (FDMA) for gathering,classifying and pigeonholing fire service data of foreign countries and for assisting
Japanese fire service personnel in making good use of them.
IFSIC is managed by the managing committee, which is composed of the chairman,
assistant vice‐commissioner of FDMA, and seven (7) members who are representativesof non‐profit Japanese organizations concerned with fire service.
Its secretariat is located in the Fire Protection Equipment and Safety Center of Japan.
IFSIC also translates Japanese laws and ordinances concerning fire service andintroduces them to fire service personnel from foreign countries.
