n. A physical situation with potential for harm or damage.
Hazard refers to a physical situation with potential for harm or damage from a specified peril at a specific place and time. Hazards are generally named for their associated peril (the source of the hazard). For example, a combination of deep, unstable snow and steep slope creates an avalanche hazard -- a physical situation with potential for a harmful or damaging avalanche. Wildland fire hazard refers to a physical situation (defined by the fuel, weather, topography at a particular point in space and time) in which wildland fire can cause harm or damage. A hazard exists if the source of hazard has the potential for causing harm or damage, even if no people or property are exposed to it at that place or time.
