Light hazard environments usually contain a limited amount of combustibles of which class?

Light hazard environments are characterized by a limited amount of combustible materials that are primarily solid materials, which typically fall under Class A. This class includes ordinary combustibles such as wood, paper, cloth, and certain plastics. In light hazard scenarios, these materials are present in small quantities and are well separated from one another, reducing the potential for rapid fire spread.

Class D refers to combustible metals, which are not commonly associated with light hazard environments. Class B involves flammable liquids and gases, which would not be present in limited amounts typically classified as a light hazard. Class M does not fit within the standard fire classification framework, thus making it less relevant in this context. Therefore, the designation of Class A for light hazards accurately reflects the nature of the combustibles typically found in these environments.
