WebMay 9, 2014 · The hazard rating system they created is called the NFPA 704 Diamond, and the four attributes that are evaluated are flammability, health, reactivity, and special hazards. Each attribute is rated from 0 to 4, based off of specific metrics, with the higher the number being a more dangerous hazard. It is important to understand the hazard rating ... WebThe rich flammability limit is about 4.8% by volume or partial pressure. Flammability limits are not absolute, but depend on the type and strength of the ignition source. Studies on flammability limits of hydrocarbon fuels have shown that the stronger the source of the ignition stimulus, the leaner the mixture that can be ignited.
