-Timber frame construction is a brick wall, wood Windows and doors, roofs, beams and columns, floors consisting of a single-layer, multi-layer housing.

I. basic features
1. variety, use is broad in scope.
(1) by purpose. ① civil buildings such as housing, offices, hospitals, schools, shops, hotels, restaurants, theaters, halls, gym, etc. ② industrial buildings such as the class factory, warehouse, etc. ③ farm structures: grain, cotton warehouse, organic farming, irrigation, greenhouses, etc.
(2) classification according to architectural layers. There is a single-layer, multi-layer. Multiple layer generally not more than 5 layer. A few brick building with basement, most of the top there is boring.
(3) classification according to architectural form. Civil architecture, most are modular residential buildings; public buildings such as offices, schools, hospitals, hotels, etc., mostly corridor type.
2. brick building is basically to brick and wood as the main body.
3. old brick building is combustible hollow wall, flooring, architectural contiguous, channel narrow, narrow and steep stairs, corridors and the personnel.

2. fire characteristics
1. burning fiercely, and spread rapidly. -Timber frame construction of doors, interior wall, stairs, floor, are used for wood and other combustible materials, fire, the fire will be in room along flammable components and the spread of the fire, once articles burn through doors, Windows and ceiling (ceiling) or the housing cover, the fire quickly spread.
2. easy to form a solid fire. Brick architecture of the building by the fire, the fire was subject to rapid spread to the horizontal, vertical spread (the top layer, to the stuffy top) prominent, easy to form a solid combustion.
3. building easy to collapse. -Timber frame construction, is to use wood as beams, columns, floors, in the event of fire, beams, columns, floors, in a certain period of time, because of the loss of load-bearing capacity building collapse; stuffy top fire of the collapse of the housing cover, particularly prominent.
4. easy to cause casualties. Brick floors of residential buildings, residential professionals, evacuation channels and steep stairs, narrow corridors, once the burn-through room or room cover collapse, pyrotechnics will rapidly enter the stairs, corridors and sealing evacuation channels trapped workers cannot escape, is easy to result in staff being burnt, smoke, toxic gases asphyxia and danger of poisoning.

Three basic requirements, fire fighting
Based on and fully exploit the existing fire-fighting equipment, evacuation and rescue personnel actively to control the fire, the eradication of fire.

Four elements, fire fighting tactics
1. the first "Save" the guiding ideology, correct handling of rescue and fire fighting. When the spread of violent and threatening trapped personnel safety, fire fighting, rescue should be taken simultaneously tactical measures.
2. stop the fire was horizontal, vertical and spread to the adjacent buildings.
3. implement in the melee attack, fast-break.

5. fire-fighting measures and calls to action
(A) fire Scout
1. external observation and ask the insiders. Quickly learn about the fire and the fire spread orientation, trapped people.
2. internal surveillance.
(1) the amount of trapped people, position, and the rescue and evacuation routes.
(2) fuel parts and its scope, the spread of fire and the main development direction.
(2) evacuation and rescue personnel
1. through the radio, and called, stable buildings are smoke and fire siege of emotions.
2. fire officers wear good personal protective equipment, when the stairs are pyrotechnics sealing when the water gun shield, fire ladder, cite high car or a window, such as forcibly assume rescue downpipes.
(3) fire-fighting measures
1. when the fire in the building of internal combustion, fire fighting attack within close quarters, the fire floor upper and lower ignition layer should be assigned to block the spread of fire vertical water gun.
2. when the fire broke through the roof and the threat of adjacent buildings, you should protect the adjacent building and architecture from the outside to shoot water fire extinguishing the fire.
(Iv) the fire water supply
Brick buildings around the fire water less, according to the nearest water occupation of water fire extinguishing, fire-fighting water occupation outlet nearby; when water farther away from the fire, the water supply for fire engines relay should be adopted for ensuring combat vehicles water needs.
(V) diffussion
Take full advantage of mist flow and movement of machinery and equipment for exhaust, or take the open doors and Windows, local breaking building exhaust.

6. considerations
1. a commitment to cutting-edge fire fighting and rescue tasks of fire detection, to wear a good personal protective equipment, water gun cover necessary application.
2. in the roof of the fire, to avoid stepping on empty fall.
3. is not available in large diameter water gun directly impact load-bearing walls and beams, columns, etc., to prevent the collapse of the housing impact while.
