Firefighting equipment is an important weapon for human firefighting. With the rapid development of science and technology, the mutual infiltration of various fields has brought vitality to the updating and development of fire equipment. There are many types of fire extinguishing equipment. From automatic fire alarm systems, fire extinguishers, fixed fire extinguishing systems, water pumps, vehicles and water supply equipment, personal and life-saving equipment, communication dispatch and command systems to fire extinguishers and flame retardants, it can be said to include metallurgy. Machinery, power transmission, light industry, electronic equipment, computers, chemical engineering, etc. Materials and other scientific fields. With the popularization of fire-fighting equipment such as fire prevention, firefighting, and emergency rescue, the overall level of fire prevention and fire resistance in society has significantly improved. Fire protection technology has become an important driving force and guarantee for the development of China's fire protection industry. Firefighting equipment refers to equipment used for firefighting, fire prevention, and fire accidents. Fire Equipment Common fire extinguishing equipment: fire extinguishers. According to the type of pressure driving the fire extinguisher, it can be divided into three categories. 1. Gas storage fire extinguisher. A fire extinguisher is a type of fire extinguisher that is driven by the pressure of compressed or liquefied gas released by the cylinder of the fire extinguisher. 2. Accumulated fire extinguisher. A fire extinguisher is a type of fire extinguisher that is driven by the pressure of compressed gas or extinguishing vapor within the same container. 3. Chemical reaction fire extinguisher. A fire extinguisher is a type of fire extinguisher that is driven by the gas pressure generated by a chemical reaction inside the extinguisher. Firstly, it should be placed at a fixed point rather than randomly moving. The second is to regularly inspect and reinstall fire extinguishers, and regularly check whether the fire extinguishing equipment is in good condition. The third is appointment management. Fire equipment should be regularly inspected, and if there is any loss or damage, it should be reported to the leader and supplemented in a timely manner. The fire equipment management is responsible for this.

The validity period of the fire protection product testing report is three to five years, and the validity period of the fire protection product certification certificate is usually four years. You can log in to the China Fire Protection Product Information Network to search for fire protection products. You can search by the type of fire protection product, the enterprise of the fire protection product, or type approval, or 3C certification. Fire fighting products refer to products specially used for fire prevention, fire fighting and rescue, fire protection, refuge and escape. Mandatory Product Certification Information: Fire truck (fire truck, dedicated fire truck, elevated fire truck, backup fire truck, airport fire truck, fire truck accessories) Fire hose (lined fire hose, wet fire hose) Fire alarm equipment (fire alarm triggering device, fire alarm device, fire electrical control equipment) Sprinkler fire extinguishing equipment (sprinkler alarm valve and accessory water flow indicator fire pressure switch).

The fire water gun, which is manually controlled for spraying into the building outside the first floor, can generally be used below the 18th floor or within 50 meters. There are also some special semi fixed ones with a maximum height of 160 meters.

Firefighting equipment refers to equipment used for firefighting, fire prevention, and fire accidents. Equipment used for professional firefighting. Common fire-fighting equipment includes fire extinguishers, which can be divided into three types according to the pressure type of the fire extinguisher: gas storage fire extinguishers, pressure storage fire extinguishers, and chemical reaction fire extinguishers. A fire extinguisher driven by the pressure of gas generated by chemical reactions inside the extinguisher. A fire extinguisher that is driven by the pressure of compressed gas or extinguishing vapor in the same container as the fire extinguisher. Fire extinguishers specifically include dry powder fire extinguishers, carbon dioxide fire extinguishers, household fire extinguishers, vehicle fire extinguishers, forest fire extinguishers, stainless steel fire extinguishers, water based fire extinguishers, suspended fire extinguishers, gun type fire extinguishers, fire extinguisher boxes, fire extinguisher racks, etc. Indoor fire hydrant system, including indoor fire hydrants, water hoses, and water guns. Fire extinguishers can be divided into five categories based on the filled extinguishing agents. The first category is dry powder fire extinguishers, and there are mainly two types of filled extinguishing agents, namely sodium bicarbonate and ammonium phosphate fire extinguishing agents. The second type of carbon dioxide extinguisher, the third type of foam extinguisher, the fourth type of water extinguisher, and the fifth type of halon extinguisher.

1. Check the integrity of water hoses and fasteners to prevent unnecessary harm to users and waste of firefighting time 2. Lay the water hose in the direction of the fire. As the hose will become straight after flushing, try to lay it in a straight line as much as possible. At the same time, avoid moving objects near the hose and prevent debris from causing secondary harm to rescue personnel 3. Connect the water hose and hydrant port, pay attention to the direction of the hydrant port and evacuation direction, and pay attention to the angle of the hydrant head and the length of the branch pipe (20200515) for construction and budgeting, for the convenience of rescue use 4. When opening the hand wheel of the fire hydrant head, it must be done slowly. If it is too fast, it can easily cause excessive hydraulic reaction force and cause harm to the user (due to the dependence of the fire hydrant pump on (20200608), the fire hydrant pump will automatically start after opening the hand wheel of the fire hydrant head, so there is no need to worry about starting the pump, and the situation where the water pump cannot work is not considered temporarily). Two people must operate the DC water gun, so it is not careless 5. After extinguishing the fire, organize and use items. Conclusion: The cost work is only a part of the project process. In the fire hydrant system, special attention should be paid to the calculation of the length of the branch pipes connecting the fire hydrant box, considering the convenience of water flow and personnel operation during rescue; I am for everyone, everyone is for me, and a harmonious society requires us to work together.
