Fire is a serious public safety incident that can cause loss of life and property. Even with the prevalence of modern fire protection systems, we still need to understand how to effectively fight and protect ourselves in the event of a fire. The following are the basic methods of fighting fires and how to operate them:
In the early stage of a fire, it is very important to use a fire extinguisher to effectively control the spread of the fire. However, there are some problems with the operation method you provided, and the correct operation steps are as follows:
1.First, make sure you are in a safe location, away from fire and smoke.
2.Check that the fire extinguisher is intact and that the pressure gauge pointer is within the green safety range.
3.Shake the fire extinguisher before use to loosen the dry powder.
4.Pull out the safety latch (not the safety pin) on the fire extinguisher, which is usually located on the top of the fire extinguisher or near the handle.
5.Stand upwind, about 2-3 meters away from the fire.
6.Aim the fire extinguisher nozzle at the root of the fire, not the flame.
7.Press firmly on the handle of the fire extinguisher and start spraying the dry powder.
8.Strafe left and right, completely covering the root of the fire source until the flame is extinguished.
9.After the flame is extinguished, observe for a period of time to make sure the fire source does not rekindle.
Please note that different types of fire extinguishers may be used in slightly different ways, but the basic principles are the same. When using a fire extinguisher, be sure to follow the manufacturer's operating guidelines and safety regulations.
Water is indeed a commonly used extinguishing agent when fighting general fires, as it can quickly reduce the temperature of the fire source and stop the contact of oxygen with the burning substance. However, in some special cases, such as oil and electrical fires, the use of water may cause the fire to worsen or cause other safety concerns.
In the case of oil fires, the density of water is greater than that of oil, and when water is mixed with oil, the oil floats on the surface of the water, which may cause the fire to spread. In addition, water has a low boiling point and may not be effective in lowering the temperature of an oil fire. In this case, it is recommended to use a dry chemical fire extinguisher, a carbon dioxide fire extinguisher, or use a wet towel, sand, etc. to extinguish the fire.
In the case of electrical fires, water is electrically conductive and can lead to electric shock accidents. Therefore, when dealing with electrical fires, non-conductive fire extinguishing agents such as dry chemical fire extinguishers, carbon dioxide fire extinguishers or special electrical fire extinguishers should be used. At the same time, ensure that the fire is extinguished in the event of a power outage.
Fire blankets are an effective fire extinguishing tool, especially for extinguishing initial fires, especially kitchen oil fires. The main function of the fire blanket is to prevent the contact between oxygen and the burning substance by covering the fire source, so as to achieve the purpose of extinguishing the fire. Here are the correct steps to use a fire blanket:
1.In the early stages of a fire, quickly find the fire blanket and remove it from the packaging.
2.Hold both handles of the blanket with your hands and carefully spread out the blanket.
3.Quickly cover the fire blanket over the fire source, making sure that the fire source is completely covered and leaving no gaps.
4.Press down on the fire blanket with your hand so that it fits snugly against the fire source to prevent air from entering.
5.Wait for the fire to extinguish and do not remove the blanket to avoid re-ignition.
6.After the flame is extinguished, check that the fire source is completely cooled to ensure safety.
Please noteFire blankets are not suitable for electrical, gaseous, or other fires that require the use of a specific extinguishing agent. In these cases, use an appropriate fire extinguisher or extinguishing method. At the same time, regularly check the condition of the fire blanket to ensure that it is in good condition so that it can be used normally in an emergency.
Fire extinguishing sand is a common fire extinguishing material, especially suitable for oil and metal fires. The main principle of extinguishing sand is to extinguish the fire source by covering the fire source and preventing oxygen from coming into contact with the burning substance. Here are the correct steps to use fire sand:
1.In the early stages of a fire, quickly find a place to store fire sand.
2.Use your hands or tools (e.g., shovels) to take an appropriate amount of fire extinguishing sand.
3.Throw the fire sand directly at the fire source, and try to completely cover the fire source.
4.If possible, build a firewall around the source of the fire with fire sand to slow the spread of the fire.
5.Wait for the fire to go out, and pay attention to the source of the fire to prevent it from re-igniting.
6.After the flame is extinguished, check that the fire source is completely cooled to ensure safety.
Please note that fire extinguishing sand is not suitable for electrical, gaseous, or other fires that require the use of a specific extinguishing agent. In these cases, use an appropriate fire extinguisher or extinguishing method. Regularly check the storage status of fire extinguishing sand to ensure that it is dry and free of impurities, so that it can be used normally in an emergency.
Dry chemical fire extinguishers are a very common and effective fire extinguishing tool that is suitable for many types of fires, including solid, liquid, and gas fires. The main ingredient is dry powder, a fine powder that forms a blanket layer over the ignition source, isolating oxygen and preventing combustion from proceeding. The correct procedure for using a dry chemical fire extinguisher is described above.
It should be noted that although dry chemical fire extinguishers are suitable for a variety of fires, it is still necessary to confirm the type of fire source before use to avoid aggravating the fire with unsuitable fire extinguishing agents. In addition, dry chemical fire extinguishers can contaminate electronic equipment, so special care should be taken when extinguishing such fires.
In general, being familiar with and using a dry chemical fire extinguisher correctly can effectively control the fire in the early stage of the fire and prevent the fire from expanding.
Foam fire extinguishers are a common type of fire extinguisher that is suitable for extinguishing liquid and electrical fires. The working principle of the foam fire extinguisher is to produce foam, which is covered on the surface of the fire source to form a layer of thermal insulation to prevent oxygen from coming into contact with the burning substance, so as to achieve the purpose of extinguishing the fire. The correct steps for using a foam fire extinguisher are described above.
Please note that different types of foam fire extinguishers may be used in slightly different ways, but the basic principles are the same. When using a foam fire extinguisher, it is important to follow the manufacturer's operating guidelines and safety regulations. At the same time, foam fire extinguishers are not suitable for extinguishing water-soluble liquid fires (such as alcohols, ketones, etc.) and metal fires. In these cases, use an appropriate fire extinguisher or extinguishing method.
In the event that the fire cannot be extinguished immediately, regardless of the size of the fire, you should call the police on 119 immediately. Professional firefighters have rich experience in fire fighting and advanced fire extinguishing equipment, and can take appropriate fire extinguishing measures according to the fire situation to protect people's lives and property.
While waiting for the arrival of firefighters, here are some things you can do:
1.Stay calm, quickly assess the fire and surroundings, and determine whether you have the ability to extinguish the source of the fire on your own.
2.If the fire cannot be extinguished, immediately organize the evacuation of people away from the source of fire and smoke.
3.Close doors and windows to slow the spread of the fire.
4.Use simple fire extinguishing tools such as fire extinguishers, fire blankets, and fire extinguishing sand to try to extinguish fire sources, but pay attention to safety.
5.If possible, notify the surrounding neighbors and work together to deal with the fire.
6.Do not return to the fire to collect your belongings to avoid danger.
Remember, in the event of a fire, keeping yourself and others safe is paramount. In the event that you are unable to extinguish the fire source on your own, it is wise to call the police in time and wait for professional rescue.
