Modern fire fighting trucks are usually equipped with steel ladders, water guns, portable fire extinguishers, self-contained breathing apparatus, protective clothing, rescue tools, first aid tools and other equipment, and some of them are also equipped with large fire fighting equipment such as water tanks, water pumps, and foam fire extinguishing devices. Today we will take a look at how fire fighting trucks should be used correctly. Let’s take a look at it together.
Here is the content list:
How to properly use fire fighting trucks in disaster relief?
The position of parking fire fighting trucks should be conducive to the quick start later
Precautions during the use of fire fighting trucks
Maintenance instructions for fire fighting trucks
First of all, when driving fire fighting trucks to a fire crisis place, first park the vehicle in a place where it is easy to rescue, and then start the rescue deployment by the instructor. Driving faster in order to fight the fire is certainly a top priority, but the speed must be high. It is very safe. If there is a traffic police or someone who can clear the way for fire fighting trucks, then we must make good use of it. If multiple cars drive out together, the distance between cars must be controlled, including when parking. Several cars can’t be parked together at the same time.
Secondly, if several vehicles are parked together, there may be a problem that the vehicle cannot be driven out during the disaster relief, but it will bring huge trouble to the rescue and rescue. The drivers of fire fighting trucks must obey the command in all actions. If someone is instructed to do so, Follow the instructions. When the situation is critical and you have to make your own decision, you must be very calm and stable, and strive to complete the task. If the fire is really serious, then drive the fire fighting trucks to an open area and wait for support. Help rescue.
On the one hand, it is to better complete the fire fighting mission, and on the other hand, it is to maintain the fire fighting trucks. When arriving at the fire scene, the car should be parked firmly. Before officially starting to drive the fire truck, the driver of the fire fighting trucks should Receive some professional driving training, and the parking position should be conducive to the quick start later, because the fire field may expand at any time, and fire fighting trucks must be evacuated with people, and this is not like normal parking. We must keep fire fighting trucks at all times. Open state, and the use of fire fighting equipment on fire fighting trucks is also very particular.
When the water is turned on, the water pressure in the hose should also be increased. If the water pressure and the water volume are not the same, then the hose may eventually burst. Therefore, while increasing the water volume, also check whether the water pressure If it meets the requirements, there are fire hydrants that can be used. If there is no reservoir or lake, it can also be the water source for the fire fighting yard. It is best to have the same type of fire fighting trucks for the task. You can change the parts if there are any parts.
In the fire fighting process, only the correct use of fire trucks can extinguish the fire safely and effectively. Because some fires cannot be extinguished with water. Fighting a fire with water may be the reaction of most people when they see a fire. It is the most common extinguishing agent in our impression. The manufacturer of fire fighting trucks reminds: Some fire fighting with water may "add fuel to the fire."
For example, if an oil pan catches fire, it will cause the oil to splash; the electric appliance catches fire, and the water can conduct electricity, which may cause accidental electric shock. The appliance may explode due to a sudden drop in temperature. A fire broke out in a hazardous chemical location. These substances will chemically react with water to generate heat to make the fire larger, and may also generate combustible gas, which increases the risk of explosion. Only by using the fire truck correctly can the fire be extinguished quickly and safely.
When a fire such as alcohol, gasoline, edible oil, oil-based paint, and banana water burns, it cannot be extinguished with fire fighting trucks. The reason is that the specific gravity of these solvents is less than water. After watering, the water cannot cover them, but quickly Running under them will not be able to insulate oxygen. At this time, we will use foam fire trucks to put out the fire. There are also chemicals such as potassium, sodium, and magnesium that catch fire. Chemicals cannot be poured with water. These substances can chemically react with water, causing the water to burn even more. In addition, combustible gas may be generated, increasing the risk of explosion. In this case, we should choose foam fire fighting trucks or dry powder fire fighting trucks, because the foam has a lighter specific gravity and can cover their surface, which has an effective flame retardant effect.
fire fighting trucks need frequent maintenance to keep the car in normal condition. Drivers are often very concerned about maintenance, because they know that the car will be driven soon without maintenance, but they are heartbroken by the money they paid for maintenance. Under normal circumstances, the engine oil is changed every 10,000 kilometers or once a year. The brake oil is changed every two years, and the gear oil needs to be changed longer. In addition to the relatively fixed maintenance mileage of these three oils, other clutch oils, power steering oil, water tank water, etc. are all supplemented or replaced according to the situation.
The purpose of fire fighting trucks maintenance is inspection, and the purpose of inspection is prevention. In addition to the above-mentioned liquid things, there are some solid things on the car to change, the most common ones are spark plugs and air filters. Generally speaking, platinum spark plugs are replaced once every 100,000 kilometers, while air filters are generally replaced once every 40,000 kilometers. Then there is the timing belt and its idler set. Only the vehicles that use the timing belt need to be replaced, and the engine with the timing chain design probably does not need to be replaced until it is scrapped. The replacement of the timing belt is the most expensive item in normal maintenance, and it must not be saved. In fact, there are so few things that need to be replaced, because the real purpose of maintenance of fire fighting trucks is not to replace these consumables, but to check whether the fire fighting trucks are abnormal.
