The features of strange particle spectra originating in a fireball at central rapidity having local kinetic equilibrium are studied in detail. A comparison with recently presented experimental data suggests that the origin of the abundantly produced strange particles is a rapidly disintegrating central fireball. Critical characteristic features of the spectra, such as the shapes of rapidity distributions and the relation between the intrinsic temperature of the fireball and the observed experimental slopes of transverse mass spectra are discussed including the dependence on the experimental cuts.
