What is the risk of a fire in a residential area due to imperfect fire-fighting facilities?

No fire-fighting facilities are considered as a first-class hazard source. 1. Hazard source (point) refers to the potential accident risk factors in enterprise equipment, workplaces and posts. Once these equipment, workplaces and posts have accidents, it will lead to personal injury, building damage and equipment damage, which is the key control and management part. Specific basis for hazard classification (points): 1, places and substances with explosion, fire and burning hazards. 2. There are places and substances attached, such as collapsed, falling, falling, splashing, hurting people and tripping people. 3. Lines, equipment and places that are in danger of electric shock injury. 4. There are dangerous places such as being twisted, squeezed, bumped and pinched by machine tools. 5. There are other places and substances that are easy to cause injuries.

2. Classification of hazard sources is divided into four grades according to the degree of danger: 1. First-class hazard sources refer to dangerous posts, equipment, places and substances with high or low accident probability, but once an accident occurs, it will cause heavy casualties, major equipment accidents and major fire accidents. In this regard, we must take decisive measures to eliminate risk factors in time. 2. Secondary hazard sources refer to dangerous posts, equipment, places and substances with high accident frequency or easy to cause multiple injuries. In this regard, decisive measures must be taken to eliminate risk factors. 3. The third-level hazard source means that although it has not caused serious injuries or major equipment accidents or major fire accidents, accidents often occur or may occur, which should be eliminated or controlled. 4. The four-level hazard source refers to a kind of danger that may lead to general injury accidents.
