4 | FIRE HAZARDS 4.1 | OVERVIEW Characteristics Fire is a unique hazard in that it can result both from natural processes and from the intentional or accidental actions of people. There are three main types of fire hazards: wildfires, which affect open space and development on the urban fringe; structural fires, which occur in buildings; and industrial fires, which result from the ignition of hazardous materials. While fires are not entirely preventable, it is possible to create conditions that reduce the chances of fire and that facilitate efficient response in case fire breaks out. When a fire does ignite, quick response from firefighters and an adequate supply of water are essential in minimizing damage. Key vulnerability factors General factors that affect an area’s risk from fire hazards include its location, land uses, distance from fire stations, ease of accessibility by fire-fighting equipment, and adequacy of water supply. More specifically, the extent, severity and damage of fires are determined by several key factors affecting vulnerability. For the three types of fire examined in the safety element, these vulnerabilities include: ● Wildfires: steep and rugged topography, dense and unmanaged vegetation (especially woods and brush), accessibility to human activities, exposure to wind and sun,
