What is the difference between "light hazard" and "ordinary hazard" classifications?

The distinction between "light hazard" and "ordinary hazard" classifications is important for designing appropriate fire suppression systems. In the context of fire protection systems, "light hazard" environments are characterized by having minimal combustible materials present. This typically means that the likelihood of fire occurrence is lower, and if a fire does occur, it is expected to have a lesser intensity due to the limited availability of fuels.

This understanding is crucial because fire suppression systems, such as sprinklers, are designed based on the hazards present. In light hazard areas, the sprinkler system may be designed for less water flow, as the expectation of fire development and spread is significantly lower. Conversely, "ordinary hazard" areas contain more combustible materials, and as a result, they warrant greater water flow and a more robust sprinkler system to effectively control potential fires.

The chosen answer reflects the fundamental aspect of light hazard classifications, specifying that these areas have minimal combustibles, thus requiring different considerations in fire protection system design compared to ordinary hazards.
