Claim:
A protective helmet comprising: an outer shell comprising a generally dome-shaped section; a brim extending outwardly from the dome-shaped section by at least 2.5 inches at the rear of the helmet, the dome-shaped section and the brim consisting essentially of a thermoplastic material having a heat deflection temperature at 264 psi in the range of approximately 235° F. to approximately 400° F., and a melting point of at least 500° F.; a brim support placed adjacent the brim after formation thereof and extending adjacent at least a portion of the brim; the brim support comprising a material that is more heat resistant than the thermoplastic material and is sufficiently rigid to limit deformation of the brim upon exposure to high temperature such that the protective helmet satisfies the National Fire Protection Association 1971 standard; and an edge trim formed of a resilient material that extends around the brim support and the perimeter of the brim to encompass the brim support and retain the brim support in operative connection with the brim.
