Paris Fire Brigade
Until 1999, the firefighting in France was performed according to the "Rules of instruction and maneuvers" ("Règlement d'instructions et de manoeuvres", RIM). The firefighters acted in teams of three members, called "trinomial" ("trinôme"): one chief, one deputy chief and one support; a fire engine with eight people thus had two trinom, an engine chief ("chef d'agrès") and a driver. In the 1990s, the Paris Fire Brigade started to work with teams of two people, called "binomial teams" ("équipes en binôme") or shortly "binomials" ("binômes"). This organisation was generalised to the whole France in a departmental order signed by the minister of Internal Affairs the 3 February 1999. An engine with eight people now has three binomials, an engine chief and a driver; an engine with six people has two binomials, an engine chief and a driver.
