The interactions of Phi mesons with other pseudoscalar and vector mesons in a hadronic gas at finite temperature are studied using the Hidden Local Symmetry Lagrangian. The small mean free path obtained implies that Phi mesons produced after hadronization in relativistic heavy ion collisions will not leave the hadronic system without scattering. The effect of these findins on the time evolution of the Phi density in the expanding hadronic fireball is investigated.
