Flammability- is how easily something will burn Word Wizard synonym: inflammable Prefix in can meet not or within antonym: nonflammable FFA regulates the manufacture of highly flammable clothing. Under FFA, CPSC can issue mandatory flammability standards. Standards have been established for the clothing textiles, vinyl plastic film, carpets and rugs, children's sleepwear and mattresses and mattress pads.

Reactivity: the rate at which a substance will chemically react
