What are fire hazards?

Fire hazards refer to any conditions or factors that can increase the likelihood or intensity of a fire. This includes various elements such as combustible materials, flammable liquids, human behaviors, and environmental factors that can contribute to the ignition and spread of a fire. Identifying and understanding fire hazards is critical in risk assessment and fire prevention strategies.

The other options describe different concepts related to fire safety but do not accurately define fire hazards. Conditions that prevent fires from starting pertain to fire prevention rather than the hazards themselves. Measures to extinguish fires relate to fire suppression tactics, while physical barriers that block fire spread are part of fire containment strategies. Understanding fire hazards involves recognizing the potential risks that can lead to fire incidents.
