Cal Fire will begin rolling out new fire-hazard severity maps, which are expected to more than double the land in jurisdictions where the state will apply stricter fire-safety building requirements.
This method is more indicative of real world fire hazards, and is preferred over NFPA 255, [4] but is more expensive. Also, test results for heat, smoke , and combustion product release from NFPA 286 are suitable for use as input into fire models for performance-based design, whereas results from NFPA 255 are not.

"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [ 1 ] and revised several times since then, it defines the " Safety Square " or " Fire Diamond " which is used to ...
Ground fires use glowing combustion to burn organic matter in the soil. Surface fires burn leaf litter, fallen branches, and ground plants. Crown fires burn through to the top layer of tree foliage. [7] Fire-line intensity is the energy released per unit of measurement per unit of time and is usually a description of flaming combustion. [4]
