How many levels is the fire alarm?

Fire alarm level 5 (alarm number 1), which is the first time to receive a fire alarm (except those who report the fire and those who are classified as mountain fires/garbage fires), and the scene involves wires or vehicles outside the building; Unable to understand the situation on site when receiving the report; The building where the accident happened has an automatic fire alarm system directly connected to the fire control center, and this office can be reached within six minutes. The above does not include the buildings listed by the Ministry as needing special mobilization. The second-level alarm is the first-level fire alarm (except 1 level fire), and the places involved are designated as particularly dangerous by the department and need special mobilization. It is divided into the following four categories: hotels and hospitals; Dangerous goods (such as oil depots and power stations); Places with limited water supply (such as Hezui Village and Tangren New Village); Other places (such as radar stations, government agencies, etc. ). Three-level alarm (three-level alarm) is to point out that the moving vehicles/manpower are not enough to deal with the fire effectively. A fire in which the vehicles/manpower mobilized by the level 4 alarm and the level 3 alarm are insufficient to deal with effectively. No.5 alarm level 4 fire, and the vehicles/manpower mobilized are not enough to effectively deal with the fire. 2006-12-0117: 02: 01supplement: the first-level field commander is the fire chief, the second-level field commander is the fire chief, and the third-level field commander is the fire chief. The reason is that all wooden buildings and buildings with no more than five floors have fires.

The fire alarm is spreading.

There are three reasons why the four-level on-site command level is the evaluation level of the fire chief: first,

The lives of residents at the fire site are in danger; two

The scene of the fire is very complicated.

Potentially or especially dangerous

Need to increase equipment or manpower; three

When the fire scene is above five floors, the number of fire hoses can be increased to 25, and the level of on-site commander can be rated as senior battalion chief. The reason is that the fire spread rapidly.

Out of control.

The number of fire hoses can be increased to 50, which is obviously more than the support equipment needed for a 4-level fire.

There are five levels.

There is a disaster warning in the clock, but it is a long and wild road guide for the fire department. Every level is subdivided, and every case has to go to a wild car. It takes many fields to make an ic for a team leader.

I'll tell you about each car again and I'll tell you everything.

Each floor 1 normal high-pressure lifting platform for fire alarm.

Medium pressure pump truck

Falling height of TL steel ladder or ALP ladder trolley or Snkl

There are four kinds of fires in LRU fine rescue vehicle or MRU large rescue vehicle No.2.

Every kind of car goes to the same place, and the same car talks about the hotel fire. It is necessary to go to the HP elevator.

Medium pressure pump truck

TL steel ladder 50m or TL steel ladder 52m or ALP ladder trolley 53m.

The ALP ladder or Snkl is falling high.

LRU fine rescue vehicle or MRU large rescue vehicle.

The food supply truck (dispatched 30 minutes after the time to ascend to the left third floor) has a 2-horsepower lifting platform for the No.4 fire.

4 pump trucks

Three 50-meter TL steel ladders or 52-meter TL steel ladders or 53-meter ALP ladder carts.

3. LRU fine rescue vehicle or MRU large rescue vehicle

2 throat cars

If there is a disaster alarm, the food supply truck will be dispatched at the scene (30 minutes after the time of upgrading to the left third level). Otherwise, the special service of existing vehicles will jump off a building.

water logging

Fall into the river

Save animals

Planes, large and small, crashed.

On-site command level evaluation of fire alarm series cause dispatching equipment. The first-class fire chief already knows that the wires are leaking or garbage is burning at the stairs.

Or four fire engines with unknown fire spread.

ambulance

There are zero to five fire hoses, and the fire chief encounters special danger when putting out the fire or the fire location is known to be dangerous.

Such as dangerous goods warehouse

Fire hoses in hotels and other places can be increased to five 3-level alarm fires. Fire officials are responsible for fires in all log cabin areas and buildings with no more than five floors.

The fire alarm is spreading.

The first batch of firefighters at the scene failed to effectively deal with fire hoses, which can be increased to ten fourth-degree fires. The fire chief has three situations: first,

The lives of residents at the fire site are in danger; two

The scene of the fire is very complicated.

Potentially or especially dangerous

Need to increase equipment or manpower; three

The number of fire hoses above the fifth floor can be increased to 25, and the fire spreads rapidly in the senior district.

Out of control.

The number of fire hoses required for fires that are significantly higher than level 4 can be increased to 50 (disaster warning), and the fire department deputy director or above is the most serious fire.

Large-scale disaster scene or multiple fires at the same time.

It takes a long time and the assistance of the army or other emergency services, and all firefighters are mobilized to the scene for rescue.

Reference: PE-pt/ peng /firehome/firelv

Fire alarm is divided into one to five levels, and the level can be upgraded according to the situation.

* * * is divided into five grades. Wen Zi has answered the same question before. . knowledge.yahoo/question/？ qid=7006022800032

Basically, there are five fire alarm levels, and the first-class fire scene commander level is the evaluation level of the fire chief, on the grounds that he knows that the wires are leaking or the stairwell is burning garbage.

Or the fire spread is unknown, and the equipment dispatched is 4 fire engines.

ambulance

There are zero to five firefighters, and the level of the second-class fire scene commander is rated as the fire chief. The reason is that the fire is particularly dangerous or the known fire location is dangerous.

Such as dangerous goods warehouse

Fire hoses in hotels and other places can be increased to five three-level fire scene commanders, and the rating of the fire chief is because there are fires in all log cabin areas and buildings with no more than five floors.

The fire alarm is spreading.

The first batch of firefighters failed to effectively cope with the dispatch of equipment and fire hoses, which can be increased to 10 four-level fire scene commanders for the rating of the fire warden. There are three reasons: first,

The lives of residents at the fire site are in danger; two

The scene of the fire is very complicated.

Potentially or especially dangerous

Need to increase equipment or manpower; three

When the fire site is on the fifth floor and above, the number of fire hoses can be increased to 25, and the commander level of the fire site is designated as senior battalion chief. The reason is that the fire spread rapidly.

Out of control.

The number of fire hoses can be increased to 50, which is obviously more than the support equipment required for a four-level fire. (Disaster warning) The on-site command level is above the deputy director of the Fire Department. The reason is the worst fire.

Large-scale disaster scene or multiple fires at the same time.

It takes a long time and the assistance of the army or other emergency services, and all firefighters are mobilized to the scene for rescue.

There is fire 1, fire 2, fire 3, catastrophic alarm.
