Unlike conventional tracers, STREAK rounds are NOT an incendiary, they don`t use burning metals to generate light. Replacing fire-hazard burning metals is a non-flammable phosphor material that utilizes the light emitted during the discharging of the round to make STREAK glow.  STREAK does NOT generate heat, making STREAK rounds safe to use in environments where traditional tracers are prohibited and can be a serious fire hazard.
