What type of hazard burns moderately fast and produces a lot of smoke?

The type of hazard that burns moderately fast and produces a lot of smoke is classified as an ordinary hazard. Ordinary hazards typically include common materials such as wood, paper, and cloth, which are known to ignite easily and burn at a moderate rate. When these materials catch fire, they can produce significant smoke due to the combustion of organic matter, which is a characteristic of ordinary combustibles.

Understanding this classification is essential for fire safety inspections, as ordinary hazards require careful attention to prevent fire incidents. In comparison, flammable hazards ignite rapidly and burn quickly, producing flames but not necessarily a lot of smoke. Explosive hazards involve materials that can cause explosive reactions rather than sustained burning, and non-combustible hazards are materials that do not burn at all, producing no smoke during a fire. Recognizing the characteristics of these different hazards is vital in identifying fire risks and implementing effective safety measures.
