Methods and Precautions to Extinguish Small Fires at Initial Stages
2017-10-20 14:51:00 gdemo.gov.cn

Domestic fires are always confined to indoors at the initial stage and do not spread very far. It is the best time to put out a fire when it first ignites. As long as it is detected timely,  it can be put out by just a few people with some fire-fighting equipment. Otherwise, with the extension of burning time and the increase of temperature, the surrounding combustible materials and building components can be heated rapidly. Air convection will increase, the burning speed will accelerate and the burning area will expand rapidly. As a result, the burning stage is formed and the fire becomes difficult to control. If the flame has already gotten out of the doors, windows and roofs and the partial building components are burned, gases and smoke will fill in the house. The fire will break through and extend to a violent stage and become hard to extinguish only by individuals. Therefore, considerable force and appropriate measures should be taken in the initial phase to control and extinguish the fire so that people’s life and property safety can be secured. Here are some tips from fire experts.

 

How to extinguish a fire at the initial stage:

 

When a fire ignites, it is small and controllable that you can extinguish it with simple and easy fire-fighting tools, such as yellow sands, soils, cement, slag, lime, iron plates, lids, wet quilts, wet sacks and simple water containers including buckets,  pots, basins and tanks. In addition, you can use whatever can fight the fire at the initial stage such as the brooms, mops, clothes, slippers, gloves and other objects in a dorm. When possible, you can extinguish the fire directly with a fire extinguisher or a fire hydrant.

 

Specific examples of fire fighting:

 

1. When a frying pan catches fire, quickly cover it with the lid and move away the pan. When the lid isolates the burning oil from the air, the oil will gradually die out due to a lack of  air.

 

2. Similarly, you can isolate the burning objects from the air and put out the fire by completely covering the burning objects with sands, soil, wet blanket, wet sacks and even talcum powder.

 

The priority of the fire emergency is to put out the fire at the initial stage by utilizing simple and easy tools and materials at hand to block the necessary conditions for the fire that just occurred.

 

Basic methods of fire fighting:

 

According to different situations in the fire fighting, timely measures such as intercepting, fast break, smoke evacuation, isolation and other basic methods should be taken.

 

1. Interception

Blocking the fire to prevent the spread or slow down the spreading speed and stopping fires in the interception process are the basic fire fighting methods, which combine active defense and active attack.

 

In practice, when the fire scene is inaccessible, , water guns and water curtains should be decisively set up in the direction of spread based on the burning objects and the situation of the scene. Moreover, close the fire doors and pull down fire resistance shutters and smoke screens to intercept the spread and prevent the fire from expanding.

 

2. Fast break

When the ignition source is accessible, fire extinguishing equipment around the fire should be immediately used to control the fire in the early stage of low temperature and less smoke.

 

3. Smoke evacuation

Discharging high-temperature smoke from buildings through doors, windows and broken holes is an important measure to guide the direction of the fire spread and to minimize losses.

 

4. Isolation

According to actual needs, large combustion zones and complex fire scenes should be divided into two or several battle sections to deal with respectively to put out the fire.
