Commonly used firefighting equipment is carbon dioxide fire extinguishers.

Dry powder fire extinguishers, cart fire extinguishers, smoke masks, fire hydrant boxes, water hoses, power storage signs, emergency lights, alarm bells, alarm buttons, smoke detectors, sprinkler heads, fire extinguisher boxes, fireproof clothing, oxygen self-rescue breathing apparatus, life-saving descenders, fire-resistant life-saving ropes, Taiping axes, safety helmets.

Firefighting rubber boots, walkie-talkie.

Flashlights, high-frequency whistles, etc.

Fire protection facilities refer to automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings.

and other fixed facilities. Automatic fire-fighting facilities are divided into automatic facilities for electric systems and automatic facilities for water systems. The electrical system is a device that can automatically alarm the police in the event of a fire accident. These devices are connected to a host unit by installing probes in various locations, and then connecting all probes to a single mainframe.

When the probe detects signs of fire, such as smoke and high temperature, it will pass the information to the host, which will alert the staff by sounding the alarm and displaying the cause of the alarm. The water system facilities are diverted through the water pipe in the place where there is more water and goods, and the water outlet of the fire water is blocked with a sprinkler head in the state of greater water pressure. The glass tube on the sprinkler will automatically burst when the temperature is high, and then the sprinkler head can evenly spray water to achieve the purpose of extinguishing the fire.

Summary. Performance and use of fire hydrant Performance: The fire hydrant is directly connected to the water pipe network, and there will be a pressure of about 3 kg of clean water when it is opened at any time.

It is suitable for fighting wood and cotton wool fires. How to use: Indoor fire hydrants are generally set on the walls of the public parts of the building, with obvious signs, and there are water hoses and water guns inside.

When a fire occurs: 1. Find the fire hydrant closest to the fire site, open the fire hydrant box door 2. Break the glass surface of the alarm and press the alarm. 3. Take out the hose, connect one end of the hose to the water outlet of the fire hydrant, connect the water gun at the other end, and pull it to the vicinity of the ** point before opening the fire hydrant valve.

Precautions: Only when it is confirmed that the power supply at the fire scene has been disconnected can water be used to extinguish the fire.

Performance and use of fire extinguishers Performance: Fire extinguishers are used to extinguish initial fires, and the type of fire extinguishers equipped in our school is portable fire extinguishers. How to use:

1. Bring the fire extinguisher to the upper hand of the fire near the place where the fire is burning 2, pull out the safety pin 3, hold the nozzle tightly with one hand 4, pinch the pressure handle with the other hand 5, and aim the nozzle at the root of the flame to strafe. (3) Precautions for participating in fire extinguishing The fire scene is a place with a large number of people and complex conditions. In order to quickly and effectively extinguish fires, it is necessary to have unified command, so as to ensure the integrity and coordination of firefighting battles, avoid affecting the effectiveness of firefighting, and better complete the firefighting work.

1. Obey the command in all actions; 2. Pay attention to your own safety and avoid **; 3. When using water to extinguish a live fire, the power supply must be disconnected first, and it is strictly forbidden to put out the live fire; 4. Prevent twisting and bending when using water hoses; 5. When extinguishing liquid fires (gasoline, alcohol), the liquid surface cannot be sprayed directly, and it is necessary to sweep about 10 cm on the liquid surface from near to far, covering the burning surface and cutting the flame;

How to use fire hydrants and fire extinguishers.

Hello, the following is how to use fire hydrants and fire extinguishers: Fire hydrants (1) At the fire scene, it is necessary to notify the surrounding personnel to evacuate first to ensure the safety of personnel. (2) Find a nearby fire hydrant, disassemble the protective cover, and remove the fire hydrant cover.

3) Connect the fire hose of the fire hydrant and its accessories, open the fire hydrant valve, approach the hose to the fire source, adjust the water pressure, and spray the fire extinguishing. (4) Pay attention to the water flow not to hit electrical appliances or personnel, etc., to avoid secondary accidents. (5) When the fire is extinguished, it is necessary to close the fire hydrant valve and remove the fire hose.

Fire extinguisher (1) At the scene of the fire, it is necessary to notify the surrounding personnel to evacuate and determine the type of fire. (2) Find a nearby fire extinguisher and unplug the safety pin first. (3) Pick up the fire extinguisher, stand on the back of the air cleaning mold, keep a certain distance between the nozzle and the fire source when using the fire extinguisher, press the sprinkler wrench, and spray the fire extinguishing agent to the fire source.

4) Pay attention to the direction and distance of the spray to avoid the expansion of the fire. (5) When the fire is extinguished, it is necessary to check whether it is completely extinguished to ensure that the fire source will not burn again. In conclusion, the proper use of firefighting equipment can play a vital role in the event of a fire.

In actual use, it is necessary to comply with relevant fire regulations and operating procedures to ensure safe and effective use.

When the building is within 150m of the protection radius of the municipal fire hydrant, and the water consumption for fire fighting does not exceed 15L s, the outdoor fire hydrant can be omitted.

2. Outdoor fire hydrants should be evenly arranged along the perimeter of high-rise buildings, and should not be concentrated on one side of the building.

3. The distance between the outdoor fire hydrant of the civil air defense project and the entrance of the civil air defense project should not be less than 5m.

5. Outdoor fire hydrants should be set up in a place that is convenient for fire trucks.

6. Outdoor fire hydrants should be above-ground, and when underground fire hydrants are used, there should be obvious signs. The underground type is used in cold areas, the above-ground type should be used in non-cold areas, and the anti-collision type can be used in the above-ground type if conditions permit.

7. Outdoor above-ground fire hydrants should have a diameter of 150mm or 100mm and two bolt openings with a diameter of 65mm. Outdoor underground fire hydrants should have a bolt mouth with a diameter of 100 and 65mm.

8. The protection radius of outdoor fire hydrants should not exceed 150m, and the spacing should not exceed 120m.

9. The outdoor fire hydrant should not be more than 2m away from the roadside, and it should not be less than 5m away from the outer wall of the house.

Use of fire hydrants:

1. Open the fire hydrant.

2. Take out the fire hose and extend it towards the fire source.

3. Connect the water gun.

4. Connect the water source.

5. Hold the water gun head and water pipe, open the water valve, and then extinguish the fire.

Use of dry chemical fire extinguishers:

1. Drag the pressure handle with your right hand and the bottom of the fire extinguisher with your left hand, and gently remove the fire extinguisher.

2. Carry a fire extinguisher to the scene in your right hand.

3. Remove the seal.

4. Unplug the safety pin.

5. Hold the nozzle in your left hand and the pressure handle in your right hand.

6. At a distance of two meters from the flame, press down the pressure handle with your right hand, swing the nozzle from side to side with your left hand, and spray dry powder to cover the entire combustion area.

Use of other fire extinguishers:

1. Foam fire extinguisher.

When using a foam fire extinguisher, it should be noted that people should stand upwind and try to get as close to the source of the fire as possible, because its spray distance is only 2 3 meters, and it should be sprayed from the side where the fire is most dangerous, and then gradually move, being careful not to leave sparks. Hold the wooden handle of the nozzle in your hand to avoid frostbite and imitation limbs. Because the amount of carbon dioxide in the air is too much, it is also bad for the human body, so in the occasion of poor air flow, it should be ventilated immediately after spraying.

2. Carbon dioxide fire extinguisher.

There are two types of carbon dioxide fire extinguishers: on-off type and knife type. When using, first remove the safety pin, then hold the wooden handle on the jet horn with one hand, press the duck tongue switch or rotary switch with the other hand, and finally hold the body. It is important to note that:

Once the knife fire extinguisher is turned on, it can no longer be turned off. Therefore, be prepared before using it.
